1. Features 1.1. New design, more modern and elegant appearance.

1.2. Convenient installation

--The ceiling type can be easily installed into a corner of the ceiling even if the ceiling is very narrow --It is especially useful when installation of an air conditioner in the center of the ceiling is impossible due to a structure such as one lighting

1.3. Two direction auto swing (vertical & horizontal) and wide angle air flow

--Air flow directional control minimizes the air resistance and produces wilder air flow to vertical direction. --The range of horizontal air discharge is widened which secures wider air flow distribution to provide more comfortable air circulation no matter where the unit is set up

1.4. Three level fan speed, more humanism design, meets different air-supply requirement. 1.5. Water proof by utilizing the absorbing plastic film on water collector. 1.6. Easy operation. Auto-restart function, remote control and optional wire control method. 1.7. Low noise level plus compact size

--Shape of the blades has been improved to prevent noise caused by turbulence.

Precaution on Installation MCAC-UTSM-2008-11

200 Installation

1. Precaution on Installation 1.1. Measure the necessary length of the connecting pipe, and make it by the following way. a. Connect the indoor unit at first, then the outdoor unit.

Bend the tubing in proper way. Do not harm them.

CAUTIONS: Daub the surfaces of the flare pipe and the joint nuts with frozen oil, and wrench it for 3~4 rounds With hands before fasten the flare nuts. Be sure to use two wrenches simultaneously when you connect or disconnect the pipes.

Pipe gauge Tightening torque Flare dimension A Min (mm) Max Flare shape

Φ6.4 15～16N.m (153～163 kgf.cm) 8.3 8.7

Φ9.5 25～26N.m (255～265kgf.cm) 12.0 12.4

Φ12.7 35～36N.m (357～367kgf.cm) 15.4 15.8

Φ15.9 45～47N.m (459～480 kgf.cm) 18.6 19.1

Φ19.1 65～67N.m (663～684kgf.cm) 22.9 23.3

b. The stop value of the outdoor unit should be closed absolutely (as original state). Every time you

connect it, first loosen the nuts at the part of stop value, then connect the flare pipe immediately (in 5 minutes). If the nuts have been loosened for a long time, dusts and other impurities may enter the pipe system and may cause malfunction later. So please expel the air out of the pipe with refrigerant before connection.

c. Expel the air after connecting the refrigerant pipe with the indoor unit and the outdoor unit. Then fasten the nuts at the repair-points.

1.2. Locate The Pipe a. Drill a hole in the wall (suitable just for the size of the wall conduit), then set on the fittings such as the

wall conduit and its cover. b. Bind the connecting pipe and the cables together tightly with binding tapes. Do not let air in, which will

cause water leakage by condensation. c. Pass the bound connecting pipe through the wall conduit from outside. Be careful of the pipe allocation

to do no damage to the tubing.

1.3. Connect the pipes.

1.4. Then, open the stem of stop values of the outdoor unit to make the refrigerant pipe connecting the indoor unit with the outdoor unit in fluent flow.

1.5. Be sure of no leakage by checking it with leak detector or soap water.

1.6. Cover the joint of the connecting pipe to the indoor unit with the soundproof / insulating sheath (fittings), and bind it well with the tapes to prevent leakage.

MCAC-UTSM-2008-11 Vacuum Dry and Leakage Checking

Installation 201

2. Vacuum Dry and Leakage Checking 2.1. Vacuum Dry: use vacuum pump to change the moisture (liquid) into steam (gas) in the pipe and

discharge it out of the pipe to make the pipe dry. Under one atmospheric pressure, the boiling point of water(steam temperature) is 100℃. Use vacuum pump to make the pressure in the pipe near vacuum state, the boiling point of water falls relatively. When it falls under outdoor temperature, the moisture in the pipe will be vaporized.

2.2. Vacuum dry procedure

There are two methods of vacuum dry due to different construction environment: common vacuum dry, special vacuum dry.

①. Common vacuum dry procedure Vacuum dry (for the first time)---connect the all-purpose detector to the inlet of liquid pipe and gas pipe,

and run the vacuum pump more than two hours (the vacuum pump should be below -755mmHg) If the pump can’t achieve below -755mmHg after pumping 2 hours, moisture or leakage point will still

exist in the pipe. At this time, it should be pumped 1 hour more. If the pump can’t achieve -755mmHg after pumping 3 hours, please check if there are some leakage

points. Vacuum placement test: place 1 hour when it achieves -755mmHg, pass if the vacuum watch shows no

rising. If it rises, it shows there’s moisture or leakage point. Vacuuming from liquid pipe and gas pipe at the same time. Sketch map of common vacuum dry procedure.

Additional Charge MCAC-UTSM-2008-11

202 Installation

② Special vacuum dry procedure This vacuum dry method is used in the following conditions: There’s moisture when flushing the refrigerant pipe. Rainwater may enter into the pipe. Vacuum dry for the first time ······ 2h pumping

③. Vacuum destroy for the second time ······ Fill nitrogen to 0.5Kgf/cm2 Because nitrogen is for drying gas, it has vacuum drying effect during vacuum destroy. But if the moisture is too much, this method can’t dry thoroughly. So, please pay more attention to prevent water entering and forming condensation water.

④. Vacuum dry for the second time· · · · · · 1h pumping Determinant: Pass if achieving below -755mmHg. If -755mmHg can’t be achieved in 2h, repeat procedure ③ and ④.

⑤. Vacuum plac ing test · · · · · · 1h

⑥. Sketch map of special vacuum dry procedure

3. Additional Charge Caution ● Refrigerant cannot be charged until field wiring has been completed.

● Refrigerant may only be charged after performing the leak test and the vacuum pumping.

● When charging a system, care shall be taken that its maximum permissible charge is never exceeded, in view of the danger of liquid hammer.

● Charging with an unsuitable substance may cause explosions and accidents, so always ensure that the appropriate refrigerant is charged.

● Refrigerant containers shall be opened slowly.

● Always use protective gloves and protect your eyes when charging refrigerant.

The outdoor unit is factory charged with refrigerant. Calculate the added refrigerant according to the diameter and the length of the liquid side pipe of the outdoor unit/indoor unit R(g) D(mm) L(m)

Installation 203

4. Water Drainage 4.1. Gradient and Supporting 4.1.1 Keep the drainpipe sloping downwards at a gradient of at least 1/100. Keep the drainpipe as short as possible and eliminate the air bubble.

4.1.2 The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to keep the gradient of 1/100 and prevent bending. Refer to the following table for the specification of the prop stand.

Diameter Distance between the prop stands

Hard PVC pipe 25~40mm 1.5~2m

4.1.3. Precautions

① The diameter of drainpipe should meet the drainage requirement at least.

② The drainpipe should be heat-insulated to prevent atomization.

③ Drainpipe should be installed before installing indoor unit. After powering on, there is some water in water-receiver plate. Please check if the drain pump can operate correctly.

④ All connection should be firm.

⑤ W ipe color on PVC pipe to note connection.

⑥ Climbing, horizontal and bending conditions are prohibited.

⑦ The dimension of drainpipe can’t less than the connecting dimension of indoor drainpipe.

⑧ Heat-insulation should be done well to prevent condensation.

⑨ Indoor units with different drainage type can’t share one convergent drainpipe.

4.2 Drainpipe Trap

4.2.1. If the pressure at the connection of the drainpipe is negative, it needs to design drainpipe trap. 4.2.2. Every indoor unit needs one drainpipe trap. 4.2.3. A plug should be designed to do cleaning.

206 Installation

For construction convenience, before laying pipes, use insulation material to insulate the pipes to be deal with, at the same time, at two ends of the pipe, remain some length not to be insulated, in order to be welded and check the leakage after laying the pipes.

5.2.3. Insulate for the jointing area, expanding area and the flange area ① Insulate for the jointing area, expanding area and the flange area should be done after checking leakage

of the pipes ② Make sure there’s no clearance in the joining part of the accessorial insulation material and local

preparative insulation material.

5.3 Drainage pipe insulation The connection part should be insulated, or else water will be condensing at the non-insulation part.

5.4 Note 5.4.1 The jointing area, expanding area and the flange area should be heat insulated after passing the pressure test 5.4.2 The gas and liquid pipe should be heat insulated individually, the connecting part should be heat insulated individually. 5.4.3 Use the attached heat-insulation material to insulate the pipe connections (pipes’ tie-in ,expand nut ) of the indoor unit
