NOTE: Install the drain pipe.
Install be drain pipe with downward gradient (1/50 to 1/100) and so there are no rises or traps in the pipe.
Use general hard polyvinyl chloride pipe (VP25) [outside diameter 1-1/4” (32mm)] and connect it with adhesive
(polyvinyl chloride) so that there is no leakage.
When the pipe is long, install supporters.
Always heat insulate the indoor side of the drain pipe.
When desiring a high drain pipe height, raise it up to 15” (400 mm) or less from the ceiling within a range of 6”

Connecting the pipes
Besure to use both a spanner and wrench together as shown in the drawing during connecting or disconnecting pipes
to/from the unit.
The pipe of water-in/out is pipe thread G3/4.The surface of thread should be enlaced by the two or three-circles trap.
After the water-in pipe and water-out pipe is connecting tightly,starting the water pump,then checking it’s airproof
performance.
Insulate it as shown in the drawing below.

How to connect wiring to the terminals
A. For solid core wiring (or F-cable)
(1) Cut the wire end with a wire cutter or wire-cutting pkiers, then stuip the insulation to about 15/16” (25mm) of
expose thn solid wire.
(2) Using a screwdriver,remove the terminal screw (s) on the terminal board.
(3) Using pliers, bend the solid wire to form a loop suitable for the terminal screw.
(4) Shape the loop wire properly, place it on the terminal board and tighten securely with the terminal screw using a
screw driver.
B. For strand wiring
(1) Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation to about 3/8” (10mm) of expose
the solid wire.
(3) Using a round terminal fastener or pliers, securely clamp a round terminal to each stripped wire end.
(4) Position the round terminal wire, and replace and tighten the terminal screw using a screwdriver.

Caution:
(1)the louver angle cannot be changed if the power is not no, (It moved by hand,ir may be damaged.)
(2) The grille assembly is directional relative to the air condirioner body.
(3) Install so that there is no gap between the grille assembly and the air conditioner body.

Connection of refrigerant pipe
Besure to use both a spanner and torque wrench together as shown in the drawing,connecting or disconnecting pipes
to/from the unit.
Refer to table 1 to determine the proper tightening torque (over tightening may damage the flare and cause leaks.)
When conecting the flare nut,coat the flare both inside and outside with refrigerating machine oil and initially
tighten by hand 3 or 4 turns.
Check the pipe connector for gas leaks,then insulate it as shown in the drawing below.

Outdoor unit installation
Selecting installation site
Select an installation site where the folliwing conditions are satisfied and that meets with your customer’s approval.
Places which are well-ventilated.
Safe places which can withstand the unit’s weight and vibration and where the unit can be installed level.
Places where the unit does not bother next-door neighbors.
Places where there is no possibility of flammable gas leak.
Places where things distressed in water do not exist because water drains off the outdoor unit.
Places where servicing space can be well ensured.
Places where strong wind can not blow directly to outdoor unit.
Outdoor unit installation
1.Install the unit firmly with combination of
M10 or more bolts and nuts on the
foundation that can fully support the weight
of the unit.and make sure the unit stand
vertically.

3.If there is noise caused by vibration add
rubber between the unit and the foundation,
Please.
4.When the air conditioner is heating or
defrosting,drain water of the outdoor unit
to an appropriate place with the drain hose.

Connecting the pipe.
1. Remove the flare nuts of the valves.
2. Match the piping center,tighten the flare
nuts with hand.
3. Tightening the flare nuts with a driver.
4. Romove the nuts of one-way valve.
5. Loosen the valve spindle with a hexogen
wrench and press the needle to let gas out.
6. Affter 15 seconds when refrigerant gas
leaks out, turn off the valve and fighten the
nuts.
7. Fully open valves.(Fig.9)
8. Tighten the nuts, then check whether there
is gas leaking out.
* If possible, evacuate from the one-way
valve with a vaccum pump. (Fig. 10)

Outdoor unit installation
Electric wiring
(1) Read the name plate carefully,then arrange wiring according to the “WIRING DIAGRAM”.
(2) A circuit breaker capable of shutting down power supply to the entire system must be installed.
(3) Earth properly.
(4) All wiring must be perfomed by a skilled electrican according to the “WIRING DIAGRAM”. Wrong wiring may
cause fire of electric shock.
Connect the power connecting wires
(1) Remove the front side plate (Fig.11)
(2) Break through the hole for wires and put on rubber bush.
(3) Pull all wires through the rubber bush.
(4) Connect the outdoor unit according to the “WIRING DIAGAM” of outdoor unit.Make sure to wire firmly.
(5) Tighten the wires with clamp and clasp.

Test and check item after installation
1. Prepare for test
(1) Do not turn on the power switch before all installation is finsihed.
(2) Connect wires corectly and firmly.
(3) Open the check valve.
(4) Remove all dust.
2. Testing
(1) Turn on the power switch and press “1/0” button.
(2) Press “MODE” button select COOL,HEAT,FAN,etc to test whether it
operates mormally.
3.Emergency operation.
When the batteries fail or when the remote controller is missing,operate as
shown below.
