WATER CONNECTIONS OF PRESOSTATIC VALVE OPTIONAL

*For TH-TUNE maneuver

NOTES

The pressure tap of the presostatic valve must be connected to the high pressure outlet of the unit.

The graphs show connections for heat pump units. In the case of cooling only units, do not mount the solenoid valve.

While mounting the presostatic valve, the performance of the flow switch on the compressor start-up must be time during one minute, to let the valve act.

WPHA / WPHBA

START UP

At first, start up the water pump for a few minutes.

Stop the water pump and notice if the auto purge is working. Repeat this operation 10 times.

If we proceed in this way, all the existing air will go out in the system and the water system will be filled.

The next step is to disconnect the mesh filter and clean it. The performance of the system will improve, because the mesh filter valve has a high pressure drop.

The start-up must be performed by qualified technical personnel in air conditioners.

It is necessary to make a start-up check list: Note inlet and outlet temperatures, voltage, amperage of the compressor and fan motor, as well as, discharge pressure of the compressor.

Remember to clean the air-filters after the first 4 hours of performance.

Closely supervise at least 3 cooling cycle operations.

It is very important to evacuate air from the system and clean dirt particles of the water circuit. The two

operations must be done at the same time.

ATTENTION!

Ensure that all electrical connections are well tightened.

Check if all panels are firmly secured with screws.

Verify if there is no refrigerant or oil leakage.

Verify if the unit is installed on level.

Verify is there is enough space for service and maintenance.

Check if the drain holes in the unit are not blocked. Verify that the valves work correctly.

Check if the water pipe system allows drainage to repair or stop.

Check if the crankcase heater of each compressor has been energized at least 24 hours before unit start up.

Check if the air filters are clean and correctly mounted.

Check grills, diffusers, air ducts and tarpaulins.

Ensure that the power supply is in accordance with what is stated on the serial plate.

Verify that fans are rotating in the correct direction.

The electrical power supply of the unit should agree with data on the plate.

Unit start-up at incorrect voltage and damages resulting from that are not covered by Hitecsa guarantee.

When making electrical connections always use the unit’s wiring diagram.

Verify that the compressor crankcase heater can be energized before unit start up.

Unit current supply should be within ±10% of Voltage and Amperes indicated on the unit nameplate.

Do not operate unit at different current from the one shown on unit plate.

The installer has to install line protection elements according to local laws and regulations.

The interconnecting wires have to be in protection tube or inside groove channel.

DRAINAGE

The indoor drainage isfitted with 3/4" gas connections, male (MPT).

Condensate evacuation line diameter should be equal or larger than unit drain connection depending on line length and general building configuration.

The condensate line should be pitched a minimum 2% for proper water evacuation.

If the drain line is at below 0 temperatures, then is necessary to install thermal insulation or an electric wire heater to prevent freezing which would damage the tube

It is convenient to install a trap with proper dimensions.

Disconnect the main power switch before any intervention.

ATTENTION!

Before access inside the unit through the electric box, it is MANDATORY to unplug the

electrical supply hose that MUST BE FREE of voltage for this operation.

AIR DUCTWORK

Air ducts dimensions are determined in relation to air flow and the unit’s available static pressure.

Qualified technician should make air duct design.

Use air ducts made of non-flammable material, which in case of fire will not emit toxic gases.

Use flexible connections between air ducts and the unit to avoid vibrations and noise transmission.

Indoor fan transmission adjustment

Adjust transmission in such a way that indoor motor consumption comes to nominal value.

If consumption is below nominal value it means unit air flow is too low.

To change fan speed:

1. In order to remove belt, move motor along its track. 2. Loose pulley set screws and, if necessary, move flange. 3. Tighten set screws. 4. Place belt in pulley channel. 5. Tighten belt using tensor screw.

To align fan and motor pulleys:

1. Loose fan pulley set screw. 2. Slide fan pulley along the shaft and align with motor using a ruler. Make sure that is parallel to the belt. 3. Tighten fan pulley setscrews.

To adjust belt tension

1. Loose motor mounting plate bolts and slide it. 2. Belt flexion in millimeters is estimated by dividing S by 40.

REFRIGERANT LOAD

The unit is shipped with a full charge of refrigerant 410A for operation.

If it is necessary to add or recover 410A refrigerant, always do it in LIQUID state. Charging by mistake refrigerant in gas or vapor form will result in wrong mixture conditions.

Due to the high pressure and rapid evaporation of R410A, the refrigerant cannot be maintained in the liquid phase within the filling cylinder when this method is used, generating bubbles in the glass scale and difficulty to read.

Repair immediately all refigerant leaks.

Never overcharge the system

Never use the compressor as a vacuum pump

In the event that during the operation, refrigerant loss symptoms appear, is necessary to do the leak test. The leak detectors are usually used with CFC and HCFC, they don’t work with R4104, since there is no chlorine in its composition. The leak detector for R134A may be used, but the detector sensitivity will be less (Adjusting the sensivity to 1 for R134A, the level for R410A will drop to 0,6).

To detect small leaks, it is necessary a leak detector for HCF. R410A sensitivity is about 23 g / year.

If a gas leak is found, it will be necessary to extract and completely recover the refrigerant charge. Pressurize the system with dry nitrogen. If no leakage is detected, then do the vacuum and charge again with refrigerant.

Never use oxygen for pressurizing in leaking test. Oxygen reacts violently with oil and

can cause explosion and damage, injury or even death.

If it is necessary to weld, first fill the circuit with dry nitrogen. The 410A refrigerant

burning turns out in toxic gas emission.

MAINTENANCE

It is advisable to make periodic maintenances of system operation and installation depending on the use, as well as annual revisions.

Coils: At least once a year clean condenser coils with water and detergent and later dry with air at a low pressure. Never clean coil with wire brush.

Indoor fans: Check the direction of rotation of the fans, verify their carriers. Check the transmission elements and the operating status.

Drainage system: Check if openings in the unit base for rain and defrost water evacuation are not blocked.

Refrigeration circuit: Check for oil or refrigerant leakage, noise, various system elements vibrations. Take temperature and pressure readings and record it on the maintenance form.

Electrical circuit: Make sure that all electrical cables are properly tightened. Be sure that there are not faulty terminals, conctactors, etc. Take the measurements of the volts and amperes of each phase of every compressor and fan motor. Verify the starting current. Check the operation of all relays, pressostats, phase sequence relay (of scroll compressor).

Air filters: Clean air filters after 4 hours of system operation and every 3 months (Or more depending on application) Filters can be cleaned by immersion in warm water with soap, later washed in clean water and dry.

Heat exchanger: It is necessary, at least once a year, clean the heat exchanger. The heat exchanger is cleaned by circulating the cleaning liquid inside and if possible in the opposite direction. An acid mixture at 5% is used (5% oxalic acid). Introduce the cleaning fluid through the exchanger. After this, the circuit should be cleaned with plenty of water to remove traces of acid. Refill with new water and start up the unit.

Before performing service or maintenance operations of unit, turn off main power switch to avoid personal injury and put lock on power switch to avoid that any person other than the maintenance technician can switch on electrical supply.

Conveyance of abrasive or adhesive media.

Conveyance of liquid media.

Use of the fan and add-on parts (e.g. safety grille) as a resting surface or climbing aid.

Fans with an additional diffuser (rear mounting kit) are not designed to walk on them! The ascent should be done with

auxiliary resources.

Unauthorised constructional modifications to the fan.

Operation of the fan as a safety component or for the performance of safetyrelevant functions in the sense of EN ISO 13849-

1.

Blocking or braking of the fan by inserting objects.

Loosening of fan blade, impeller and balancing weight.

All applications not listed in the intended use.

Any use of another type or that exceeds this scope will be considered an unplanned use, unless it has been contractually agreed. The manufacturer is not responsible for any damage resulting from unintended uses. In that case, the risk lies exclusively with the company or the user.

Do not connect the built-in fans to outlet pipes of gas equipment or other heating equipment.

Built-in fans with VDE approval (see rating plate) are designed to be mounted inside equipment and are not suitable for direct connection to the mains.

Reading these document and complying with all contained instructions –especially the safety notifications contained therein -are considered part of intended use.

Working on Device

Information

Danger due to electric current

Waiting period at least 3 minutes!

Attention, automatic restart!

Mounting, electrical connection, and start-up operation may only be carried out by an electrical specialist in accordance with electrotechnical regulations (e.g. EN 50110 or EN 60204)!

It is generally forbidden to carry out work on electrical live parts. Protection class of the device when open is IP00! It is possible to touch hazardous voltages directly!

The rotor is not protected against indirect contact neither by supplementary or reinforced insulation nor by connection to safety-earth in accordance with EN 60204-1, therefore the system constructor must provide protection by enclosure in accordance with EN 61140 before the motor is connected to a power source. This protection can be achieved for example by a guard grille (Product overview: Application operational area and Installation: General).

When the motor runs independently due to air flowing through or if it continues to run down after being turned off, dangerous voltages of over 50 V can arise on the motor internal connections through operation of the generator.

The safe isolation from the supply must be checked using a two-pole voltage detector.

Even after disconnecting the mains voltage, life-threatening charges can appear between the protective earth “PE” and the mains connection.

The protective earth is conducting high discharge currents (dependent on the switching frequency, current-source voltage and motor capacity). Earthing in compliance with EN specifications shall therefore be observed even for testing and trial conditions (EN 50 178, Art. 5.2.11). Without earthing, dangerous voltages can be present on the motor housing.

Maintenance work may only be carried out by suitably qualified personnel.

Through use of capacitors, danger of death exists even after switching off the device through directly touching the energized parts or due to parts that have become energized due to faults. The controller housing may only be removed or opened when the power line has been switched off and a period of three minutes has elapsed since switching it off.

The fan / motor may switch on and off automatically for functional reasons.

After power failure or mains disconnection an automatic restart of the fan takes place after voltage return!

Wait for the fan to come to a complete standstill before approaching it!

In the external rotor motor the external rotor turns during operation!

ANNEX: SAFETY FILE R410A

Causes Safety data for R410A

Toxicity Low

Skin Contact

Splashes of liquid may cause frostbite.. It is unlikely that skin absortion dangerous; It can be irritating and the liquid has a degreasing effect. Thaw affected areas with water. Remove contaminated clothing carefully because it may stick to the skin in the case of burns caused by freezing. Wash the affected areas with warm water. If irritation or blistering symptoms appears then get medical attention.

Eyes contact

Vapors cause harmful effects. Splashes of liquid may cause frostbite. Wash immediately with an ophthalmic solution or clean running water for at least 10 minutes and get medical attention immediately.

Ingestion

Very unlikely to happen, but if it happened would occur freeze burns. Do not force the patient to vomit. If the patient is conscious, wash out mouth with water and give to drink 250 ml of water; Get medical attention immediately.

Inhalation

R410A: remarkable concentrations in the air may have an anesthetic effect, unconsciousness. Exposure to extremely high doses may be suddenly fatal. At higher concentrations there is a danger of suffocation due to the reduction of oxygen content in the atmosphere. Remove patient to fresh air and keep warm and at rest. Administer oxygen if necessary. Apply artificial respiration if the patient has stopped breathing or shows signs of it. In the case of cardiac arrest apply external cardiac massage. Get immediate medical attention.

Medical Advice

This is a semiotics and supportive therapy. We observed a cardiac sensitization that can, in the presence of circulating catecholamines such as adrenaline, cause cardiac arrhythmias and subsequent arrest of the heart after exposure to high concentrations.

Prolonged exposure

R410A: An inhalation lifelong study on rats showed that exposure to 50,000 ppm resulted in benign tumors of the testis. This is not considered important for humans who have been exposed to at or below the occupational exposure limit concentrations.

Occupational exposure limits

R410A: Recommended limits: 1,000 ppm v / v - 8 hours Weighted Average.

Stability

R410A: No specification

Avoiding Conditions

Do not use in the presence of outdoor flames, hot surfaces and high humidity levels.

Dangerouse reactions

It can produce a violent reaction with sodium, potassium, barium and other alkali metals. Incompatible substances: magnesium and alloys containing more than 2% magnesium.

Harmful decomposition products

R410A: Halogen acids by thermal decomposition and hydrolysis.

Generals precautions

Avoid inhalation of high concentrations of vapour. Atmospheric concentrations should be minimized and kept as low as reasonably practicable below the occupational exposure limit. The vapour is heavier than air and collects at low level in confined spaces. Exhaust wind at the lowest levels.

Respiratory Protection

When a question about the atmospheric concentration appears, breathing apparatus approved by the Board of Health and Safety, of the independent type or the type of feeding tube should be used.
