11. Installation Instruction

s

11.1 Select the Best Location

11.1.1 Indoor Unit

 Do not install the unit in excessive oil fume area

such as kitchen, workshop and etc.

 There should not be any heat source or steam

near the unit.

 There should not be any obstacles blocking the air

circulation.

 A place where air circulation in the room is good.
 A place where drainage can be easily done.
 A place where noise prevention is taken into

consideration.

 Do not install the unit near the door way.
 Ensure the spaces indicated by arrows from the

wall, ceiling, fence or other obstacles.

 Mount with the lowest moving parts at least 8ft

(2.4 m) above floor or grade level.

11.1.2 Outdoor Unit

 If an awning is built over the unit to prevent direct

sunlight or rain, be careful that heat radiation from
the condenser is not obstructed.

 There should not be any animal or plant which

could be affected by hot air discharged.

 Keep the spaces indicated by arrows from wall,

ceiling, fence or other obstacles.

 Do not place any obstacles which may cause a

short circuit of the discharged air.

 If piping length is over the [piping length for

additional gas], additional refrigerant should be
added as shown in the table.

 Recommended installation height for outdoor unit

should be above the seasonal snow level.

 Be careful not to locate outdoor unit directly under

a roof line where falling snow or ice can cause
damage or dripping water can increase ice
accumulation and defrost cycles.

The center of installation plate should be at more than 1 at right and left of the wall.
The distance from installation plate edge to ceiling should more than 2.
From installation plate left edge to unit’s left side is 3.
From installation plate right edge to unit’s right is 4.

B : For left side piping, piping connection for liquid should be about 5 from this line.

ƻ

: For left side piping, piping connection for gas should be about 6 from this line.

1 Mount the installation plate on the wall with 5 screws or more (at least 5 screws).

(If mounting the unit on the concrete wall, consider using anchor bolts.)
o Always mount the installation plate horizontally by aligning the marking-off line with the thread and using

a level gauge.

2 Drill the piping plate hole with ø2-3/4" (ø70 mm) hole-core drill.

o Line according to the left and right side of the installation plate. The meeting point of the extended line is

the center of the hole. Another method is by putting measuring tape at position as shown in the diagram
above. The hole center is obtained by measuring the distance namely 5-1/16" (128 mm) for left and right
hole respectively.

o Drill the piping hole at either the right or the left and the hole should be slightly slanting to the outdoor

side.

11.2.1 To Drill a Hole in the Wall and
Install a Sleeve of Piping

1 Insert the piping sleeve to the hole.
2 Fix the bushing to the sleeve.
3 Cut the sleeve until it extrudes about 19/32"

(15 mm) from the wall.

CAUTION

When the wall is hollow, please be sure to use the
sleeve for tube assembly to prevent dangers
caused by mice biting the connection cable.

4 Finish by sealing the sleeve with putty or

caulking compound at the final stage.

1 Connect a charging hose with a push pin to the Low side of a charging set and the service port of the 3-way

valve.
2 Connect the micron gauge between vacuum pump and service port of outdoor units.
3 Turn on the power switch of the vacuum pump and make sure that connect digital micron gauge and to pull

down to a value of 500 microns.
4 To make sure micron gauge a value 500 microns and close the low side valve of the charging set and turn off

the vacuum pump.
5 Disconnect the vacuum pump house from the service port of the 3-way valve.
6 Tighten the service port caps of the 3-way valve at a torque of 13.3 Ibf.ft (18 N•m) with a torque wrench.
7 Remove the valve caps of both of the 2-way valve and 3-way valve. Position both of the valves to “Open”

using a hexagonal wrench (5/32" (4 mm)).
8 Mount valve caps onto the 2-way valve and the 3-way valve.

o Be sure to check for gas leakage.

 If micron gauge value does not descend 500 microns, take the following measures:

- If the leak stops when the piping connections are tightened further, continue working from step e.

- If the leak does not stop when the connections are retightened, repair location of leak.

- Do not release refrigerant during piping work for installation and reinstallation.

- Be careful with the liquid refrigerant, it may cause frostbite.

11.3.5 Piping Insulation

1 Please carry out insulation at pipe connection portion as mentioned in Indoor/Outdoor Unit Installation

Diagram. Please wrap the insulated piping end to prevent water from going inside the piping.

2 If drain hose or connecting piping is in the room (where dew may form), please increase the insulation by

using POLY-E FOAM with thickness 1/4" (6 mm) or above.

11.3.5.1 Cutting and flaring the piping

1 Please cut using pipe cutter and then remove the burrs.
2 Remove the burrs by using reamer. If burrs are not removed, gas leakage may be caused. Turn the piping

end down to avoid the metal powder entering the pipe.

11.3.6 Disposal of Outdoor Unit Drain Water

R

The unit should be mounted on a stand that suits to a local environmental requirement.
 When the Drain elbow being used, please ensure to:-

o Provide a minimum clearance of 2" (50mm) to access the bottom of base pan.
o Seal the four 25/32" (20mm) diameter holes with Rubber caps (refer to illustration below).
o Use a rigid or flexible PVC pipe (local supply) to dispose drained water from the elbow or use a stainless

steel tray (local supplied) to collect and dispose water.

Drain
elbow

ubber cap

x4

 If the unit is used in an area where temperature falls below 32°F (0°C) for 2 or 3 consecutive days, it is

recommended not to use the Drain elbow and Rubber caps, water from defrost process will trap, freeze up and
obstruct fan rotation. Water may drip from the basepan hole area during defrost function, do not stand or place
objects underneath.
