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.

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.

3) Connect the pipes.

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.

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

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.

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.

. Common vacuum dr① y procedure

l 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)

l 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.

l If the pump can’t achieve -755mmHg after pumping 3 hours, please check if there are some leakage

points.

l 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.

l Vacuuming from liquid pipe and gas pipe at the same time.
l Sketch map of common vacuum dry procedure.

②. Special vacuum dry procedure

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

. Vacuum destroy for the second time ······ ③ 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 placing test ······ 1h

⑥. Sketch map of special vacuum dry procedure

3. Additional Refrigerant 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

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

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

The drainpipe should be heat② -insulated to prevent atomization.

Drainpipe should be installed before installing indoor unit. Aft③ er powering on, there is some water in

water-receiver plate. Please check if the drain pump can operate correctly.
All connection should be firm.④
Wipe color on PVC pipe to note connection. ⑤
Climbing, horizontal and bending conditions are prohibited.⑥
The dimension of drainpipe can’t less than the connecting dimension of indoor drainpipe.⑦
Heat⑧ -insulation should be done well to prevent condensation.
Indoor units with different drainage type can’t share one convergent drainpipe.⑨

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.

4.5 Drainage test

4.5.1Drainage without drain pump
After finishing drainpipe installation, pour some water into the water receiver plate to check if the water flows

smoothly.

4.5.2 Drainage with drain pump
Poke the Water Level Switch, remove the cover, use water pipe to pour 2000ml water i① nto the water

receipt plate through the water inlet.

Turn on the power to Cooling operation. Check the pump’s operation and switch on the Water Level ②

Switch. Check the pump’s sound and look into the transparent hard pipe in the outlet at the same time to
check if the water can discharge normally.

Stop the air conditioner running, turn off the power, and put back the cover.③

l Stop the air conditioner. After 3 minutes, check if it has abnormity. If the collocation of drainpipes is

illogical, the water will flow back overfull, which will cause the alarm lamp flashes, even overflow from
the water receipt plate.

l Keep on pouring water until it gives an alarm signal for high water level, check if the pump drains water

at once. If the water level can’t fall below the alarmed water level after 3 minutes, the air conditioner will
stop. Turn off the power and drain the remained water, and then turn on the air conditioner.

Note: the drain stuff in the main water receipt plate is for maintenance. Stuff up the drain stuff to prevent water

leakage.

5. Insulation Work

5.1 Insulation material and thickness

5.1.1. Insulation material

Insulation material should adopt the material which is able to endure the pipe’s temperature: no less than
70 in the high℃ -pressure side, no less than 120 in the low℃ -pressure side(For the cooling type machine, no
requirements at the low-pressure side.)

u Example: Heat pump type----Heat-resistant Polyethylene foam (withstand above 120)℃

Cooling only type----Polyethylene foam (withstand above 100) ℃

5.1.2. Thickness choice for insulation material

Insulation material thickness is as follows:

Pipe diameter (mm) Adiabatic material thickness

Refrigerant pipe

Φ6.4—Φ25.4 10mm

Φ28.6—Φ38.1 15mm

Drainage pipe

Inner diameterΦ20—Φ32 6mm

5.2 Refrigerant pipe insulation

5.2.1. Work Procedure

Before laying the pipes, the non① -jointing parts and non-connection parts should be heat insulated.
When the gas proof test is eligible, the jointing area, expanding area and the flange area should be heat ②

insulated

5.2.2. Insulation for non-jointing parts and non-connection parts

wrong right

Gas pipe and liquid pipe should

not be put together to insulate

Insulate the gas pipe

(cooling only)

Insulate the gas pipe and

liquid pipe

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

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

of the pipes

Make sure there’s no clearance in the joining part of the accessorial insulati② on 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

6. Wiring

Please refer to the Wiring Diagram.

7. Test Operation

(1) The test operation must be carried out after the entire installation has been completed.

(2) Please confirm the following points before the test operation.

l The indoor unit and outdoor unit are installed properly.
l Tubing and wiring are correctly completed.
l The refrigerant pipe system is leakage-checked.
l The drainage is unimpeded.
l The ground wiring is connected correctly.
l The length of the tubing and the added stow capacity of the refrigerant have been recorded.
l The power voltage fits the rated voltage of the air conditioner.
l There is no obstacle at the outlet and inlet of the outdoor and indoor units.
l The gas-side and liquid-side stop values are both opened.
l The air conditioner is pre-heated by turning on the power.

(3) According to the user's requirement, install the remote controller when the remote controller's
signal can reach the indoor unit smoothly.
(4) Test operation

Set the air conditioner under the mode of "COOLING" with the remote controller, and check the following
points.

Indoor unit

l Whether the switch on the remote controller works well.
l Whether the buttons on the remote controller works well.
l Whether the air flow louver moves normally.
l Whether the room temperature is adjusted well.
l Whether the indicator lights normally.
l Whether the temporary buttons works well.
l Whether the drainage is normal.
l Whether there is vibration or abnormal noise during operation.

Outdoor unit

l Whether there is vibration or abnormal noise during operation.
l Whether the generated wind, noise, or condensed of by the air conditioner have influenced your

neighborhood.

l Whether any of the refrigerant is leaked.
