Installation
Step 2.7 Optional: Changing the
direction of the drain hose
CAUTION
•
Make sure that the indoor unit is in upright
position when you pour water to check for leakage.
Make sure that the water does not overflow onto
the electrical part.
Step 2.8 Installing and connecting
the assembly pipes to the refrigerant
pipes (assembly pipe)
Connect indoor and outdoor units with field-supplied
copper pipes by means of flare connections. Use
insulated seamless refrigeration grade pipe only,
(Cu DHP type according to ISO1337), degreased and
deoxidized, suitable for operating pressures of at
least 4200 kPa and for burst pressure of at least
20700 kPa. Under no circumstances must sanitary
type copper pipe be used.
There are 2 refrigerant pipes of different diameters:
•
The smaller one is for the liquid refrigerant
•
The larger one is for the gas refrigerant
A short liquid refrigerant pipe and a short gas
refrigerant pipe are already fitted to the air
conditioner. The connection procedure for the
refrigerant pipes varies according to the exit position
of each pipe when facing the wall:
1
Cut out the appropriate knock-out piece (A, B, C)
on the rear of the indoor unit unless you connect
the pipe directly from the rear.
2
Smooth the cut edges.
