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.
