Safety first

A few careful preventative measures will ensure the safe operation of this solar hot water

heating system.

Always wear gloves and long sleeve overalls when working with the glass tubes Mount the system to ensure people/children cannot inadvertently run/walk into

the tubes

The system should be mounted in such a way as to deter accidents

The system must be bolted down at the 4 feet position so that strong wind cannotblow it over.

We appreciate you are keen to assemble your system and no doubt have assembled it on

your front lawn full of boiling water. Do not do this - give a thought to the potential

hazard. A child running into this system would be seriously cut and burnt with scoldinghot water. Do not let this happen.

Please ensure you erect this system in a safe place such that this will never occur.

Safety tips

Wear gloves and overalls.

Erect in a suitable place out of reach of adults/children.

Do not over pressurize the system.

Read the instructions prior to assembling.

If a tube breaks, give some thought to where the 200 liters of boiling water may

end up? Into a rainwater system - not onto your head off a roof without any

spouting. Ensure that if this system is using water that is not treated, then the water is

heated to 60 degrees Celsius to avoid the risk of Legionnaires disease.

Boiling water will cause serious burns. Make sure it is plumbed in correctly and

secured.

Ensure the system is full with water during sunlight hours.

Do not fill the system with cold water if you have accidentally left it in the sun

empty.

Cover the tubes and in the evening fill slowly with cold water to prevent possiblebreakage.

Safe temperatures

Water tank storage systems are currently required to reach 80 degrees Celsius to ensurethat the water is hot enough to kill unwanted organisms that might establish in your hot

water tank. It is recommended that this temperature is reached every day, but in practice,

this is not possible in solar hot water heating systems without electric backup, typically

the case with off grid homes. The requirement for how often the temperature should beraised to 80 degrees Celsius is not currently specified in Pakistani law. A minimum of

once every week would be prudent. Many users of such systems ensure that the tank


6/13


temperature reaches 80 degrees Celsius once every as a compromise. You should buy atemperature probe so you can check this. Generally, this will not be a problem on hot

summer days but temperatures might not get above 70 degrees Celsius during poor

weather conditions.

In situations where the system is preheating swimming pools, hot tubs and as a pre heaterfor an existing house/farm hot water system then the water will be heated above 80degree Celsius and/or is being chemically/UV treated.

Intended use of this system

This system is a low cost system common in China. As such, it will generally capture

sufficient energy to pay for itself in 2-4 years (excluding all installation costs).

Spare parts are common and held in stock at local Solar Geyser distributors. Solar Geyser

has completed accelerated high temperature test for over 12 months without any leaks to

date. This is with the unit containing boiling water almost all the time.

The intended use is for:

Hot tubs

Swimming pool heating

Domestic hot water heating

Users should note that hot water heating systems normally require a buildingconsent. Such systems are normally required to be installed by a plumber. This

system does not meet all these requirements but can be legally used in certain

applications or as the user wishes to use them, accepting any liability themselves.

Solar Geysers view is that an affordable solar system is much better than no solar

system and these systems have many applications.

Please take good notice of the warnings we have given you, as Solar Geyser will not

be liable in the event of inappropriate use of this equipment.

Low-pressure systems

This is a low-pressure direct system. The water being heated by the sun is inside the glasstubes; hence the system is not able to withstand much pressure. The tanks are therefore

made from very thin stainless steel, resulting in a very cost effective product. Thewarmed water rises naturally into the tank by convection flow. These direct systems arealso very efficient as there are no heat exchangers required. As such, this low cost system

will outperform most other more expensive systems. This system is capable of boiling

water after two clear winter days.

Frost protection

The solar systems can withstand frost conditions provided minimum night time

temperatures do not go below -10 degrees Celsius.

Powder coated frame parts:

Check to make sure all components are present as detailed below.

2 vertical legs

2 diagonal legs

2 leg & tank joiner

1 tube holder4 short diagonal bars

1 short diagonal bar flat end

2 long diagonal bars2 long horizontal bar with

one flat end

1 long front bar1 bag of bolts and nuts

1 bag of bolts, nuts and

reflector fixings

You should also have a tank, 16 (15 required, 1 spare included) glass tubes, a packet of

plastic seals and plastic tube trims.

Assembly instructions:

Assemble diagonal legs withLeg & Tank joiner.



8/13

Arrange outer 2 diagonal legs so the flat side is outside, link the 2 vertical legs with the

tube holder and the long bar on the front as shown below.

Tube Holder & Diagonal Leg

Two Vertical Legs arranged with Tank Joiner and 2 horizontal bars assemble with both

vertical legs.



9/13


Assemble 4 short dioganol bars

Join 4 feet

Place Tank on the tank joiners.


10/13

Place the plastic caps in the tube

holder.

Lubricate tank seals with soap.

Lubricate tube by spreading soap

or detergent and put trim seal over

tube, flat side is pointing towards

tank.

Caution:

It is strictly prohibited to

pour cold water suddenly

into the dry vacuum tubes

exposed in the sun to avoid

blowout of the evacuatedcollector tubes. Please use

sunshade or input water

into the tubes in case of

installation under the

burning sun.

Rotate tube carefully (wear gloves)

while pushing tube upwards into

the tank. Be careful not to knock

the other end of the tube on the

fame.

Prepare the reflectors beforehand

and fit by twisting clamps 90.

The installation of reflector

panels should go in step with

the installation of vacuum

tubes.



12/13


Insert Stainless Steel pipe nipple as

hot water outlet in the upper hole.

Insert pipe nipple in the lower hole

as cold water inlet.

Top riser vent

A plastic vent is provided so that steam can vent from the system. This vent can be

extended up to 1.0m in height by gluing a suitable extension piece onto the fitting

supplied. You will need to support the extended vent with stay wires.

What to do if you break a tube.

If you should accidentally break a tube after the system has been in service for sometime, it can be difficult to remove the old broken tube, due to scale build up on the tube

surface. The best way is to spray silicon lubricant on the top of the tube with the trim

removed. Push the tube up, rotate slightly, then pull and twist the tube out. Replace with anew tube.

Spare tubes, frames and tanks are available from the local distributor or Solar

Geysers nearest office.

Warrantee:

This system has a full 12-month warrantee and Solar Geyser will hold spare partsfor as many years as possible, ensuring a good supply of spare parts and product

support.

Any defective part or parts that fail inside the warrantee period must be returned

to Solar Geyser at the customers expense. The customer may collect or arrangefor transport (at their cost) any replacement parts.

Goods are sold on a collection from site basis only. Tubes are all inspected prior

to collection and one spare tube is supplied. The buyer is invited to check all the

tubes and other parts for any defects at time of collection.

In the event of more than one tube being cracked when the system is installed, thebuyer will have to collect a replacement tube from our premises or pay for the

freight on any tubes sent. Customers wishing to have the goods freighted to them must pay for and organize

the freight themselves; any damage in freight is for the customer to resolve withthe freight company not Solar Geyser. Goods are sold for collection only to the

customer or for collection by their nominated agent.

Leaving this solar system in the sun without it being filled with water will void

this warrantee.

Do not attempt to make any new openings into the tank; this will void your

warrantee.

Do not overpressure by extend the vent pipe this will void you warrantee.
