Safety precautions for installing and relocating the unit
To ensure safety, please be mindful of the following precautions.
Warning
When installing or relocating the unit, be sure to keep the refrigerant
circuit free from air or substances other than the specified refrigerant.
Any presence of air or other foreign substance in the refrigerant circuit will cause
system pressure rise or compressor rupture, resulting in injury.
Only qualified technicians, should install, move or service this equipment.
Please follow the units nameplate and installation instruction to ensure safe
and accurate operation of product.
If there is a need to recover refrigerant during installation, ensure system is
running in cooling mode. Fully close high pressure service valve (Liquid valve)
and allow to pump-down for 30-40 seconds, then fully close the low pressure
service valve (Gas valve) and immediately remove power from unit. Do not
exceed 1 minute in pump-down otherwise system contamination or breakage
can occur.
Ensure unit is leak free by applying 500psig of dry nitrogen and check all flares
with a liquid bubble solution. Watch carefully for small bubbles indicating a leak.
Do not install unit in a area where corrosive gases or flammable gases exist.
Otherwise premature failure of product can occur, or fire.
Do not use supply (power) cords or extension cords with equipment. This
product must be installed by a certified installer. Wired per NEC codes.
Follow local and national codes for interconnection between indoor and
outdoor units.

Installation of indoor unit
Step one: choosing installation location
Provide recommendation to customer for the most ideal location to install unit.
Step two: install wall-mounting frame
1. When hanging wall mounting plate, be sure to set level, once level is set mark
all locations for mounting screws.
Drill holes and use appropriate mounting hardware. (Example: Wall Anchors,
Self Tapping Screws or other)
3. Affix wall mounting plate and ensure no flex from the wall surface to guarantee
secure mounting.
Step three: open piping hole
1. Choose the position of piping hole according to the direction of outlet pipe. The
position of piping hole should be a little lower than the wall-mounted frame,
shown as below.

installation.
● For the air conditioner without plug, an circuit break must be installed in the line.
The circuit break should be all-pole parting and the contact parting distance
should be more than 3mm.

Installation of indoor unit
Step eight: bind up pipe
1. Combine pipes, wires and drain line
in a UV rated line set covering
system.

3. Bind them evenly.
4. The liquid pipe and gas pipe should
be bound separately at the end.

2. Be sure to allow for extra line set,
wire and drain to connect to outdoor
unit.
Be sure that drain pipe is routed at
the bottom of the binded pipe. To
ensure proper drainage.
Step nine: hang the indoor unit
1. Put the bound pipes in the wall pipe and then make them pass through the wall
hole.
2. Hang the indoor unit on the wall-mounting frame.
3. Stuff the gap between pipes and wall hole with sealing gum.
4. Fix the wall pipe.

Test operation
1. Preparation of test operation
● The client approves the air conditioner.
● Specify the important notes for air conditioner to the client.
2. Method of test operation
● Put through the power, press ON/OFF button on the remote controller to start
operation.
● Press MODE button to select AUTO, COOL, DRY, FAN and HEAT to check
whether the operation is normal or not.
● If the ambient temperature is lower than 16℃(61°F) , the air conditioner can’t
start cooling.

4. Additional refrigerant may be required when extending the line-set.
● After the line-set has been extended 33ft past standard length of 25ft,
adding additional 5ml of refrigerant oil for each additional 16ft.
● The calculation method of additional refrigerant charging amount (on the basis
of liquid pipe):
Additional refrigerant charge amount = extended length of liquid line x
required additional amount per foot.
● Basing on the length of standard pipe, add refrigerant according to the
requirement as shown in the table. The additional refrigerant charging amount
per foot is different according to the diameter of liquid pipe. See the
following sheet.

Pipe expanding method
Note:
Improper pipe expanding is the main cause of refrigerant leakage. Please expand
the pipe according to the following steps:
A: Cut the pipe
E: Expand the port
● Expand the port with expander.
