· There must be no obstacles near the air inlet and outlet. · Install the indoor unit on a ceiling that can support its weight. · Maintain sufficient clearance around the indoor unit. · Before installing the indoor unit, be sure to check whether
the chosen location is well-drained.
· The indoor unit must be installed such that it is beyond public access and is not touchable by users.
CAUTION
Do not install the air conditioner in following places. · The place where there is mineral oil or arsenic acid. Resin
parts flame and the accessories may drop or water may leak. The capacity of the heat exchanger may reduce or the air conditioner may be out of order. · The place where corrosive gas such as sulfurous acid gas generates from the vent pipe or air outlet. The copper pipe or connection pipe may corrode and refrigerant may leak. · The place where there is a machine that generates electromagnetic waves. The air conditioner may not operate normally due to control system. · The place where there is a danger of existing combustible gas, carbon fiber or flammable dust. · The place where thinner or gasoline is handled.

CAUTION
· Connect the indoor and outdoor units using pipes with flared degreased and deoxidized copper pipe (Cu DHP type to ISO 1337 or UNI EN 12735-1), suitable for operating pressures of at least 4200kPa and for a burst pressure of at least 20700kPa. Copper pipe for hydro-sanitary applications is completely unsuitable.

Installation Procedure

2 Be sure to use insulator which is thick enough to cover the refrigerant tube to protect the condensate water on the outside of pipe falling onto the floor and the efficiency of the unit will be better.
3 Cut off any excess foam insulation.
4 Be sure that there must be no crack or wave on the bended area.
5 It would be necessary to double the insulation thickness[0.39 inch (10mm) or more] to prevent condensation even on the insulator when if the installed area is warm and humid.
6 Do not use joints or extensions for the pipes that connect the indoor and outdoor unit. The only permitted connections are those for which the units are designed.
AC***BNLDCH

Step 8 Performing the gas leak test
Pressure check the refrigerant system using high pressure nitrogen in order to detect basic refrigerant leaks. Before performing the vacuum process and releasing the factory R-410A charge into the refrigerant pipes, it is the responsibility of the installer to pressurize the whole system with nitrogen (using a cylinder with pressure reducer) at a pressure above 580.2 psi(4 Mpa) (gauge).

Step 9 Insulating the refrigerant pipes
Once you have checked that there are no leaks in the system, you can insulate the piping and hose. 1 To avoid condensation problems, place Acrylonitrile Butadien
Rubber separately around each refrigerant pipe. No gap
NBR

CAUTION
· Make sure that all refrigerant connection must be accessible for easy maintenance and detachment.
· Install the insulation not to get wider and use the adhesives on the connection part of it to prevent moisture from entering.
· Wind the refrigerant pipe with insulation tape if it is exposed to outside sunlight.

Step 10 Installing the drain hose and drain pipe
1 Push the supplied drain hose as far as possible over the drain socket.
2 Tighten the metal clamp as shown in the picture.

Without the drain pump
1 Install horizontal drainpipe with a slope of 1/100 or more and fix it by hanger space of 3.28~4.92ft(1~1.5m).
2 Install U-trap at the end of the drainpipe to prevent a nasty smell to reach the indoor unit.
3 Do not install the drainpipe to upward position. It may cause water flow back to the unit.
