Step 7 Installing oil traps

Check the following list and install an oil trap.

ŷ Based on cooling operation, install it on the gas side

pipe only.

ŷ Install the oil trap only in between the outdoor unit

and the first branch joint and it should be installed at

every 10 m.

ŷ Radius of curvature (R) on the oil trap are as follows;

Step 8 Connecting up and removing air

in the circuit

CAUTION

ŷ When installing, make sure there is no leakage. When

recovering the refrigerant, ground the compressor

first before removing the connection pipe. If the

refrigerant pipe is not properly connected and the

compressor works with the service valve open, the

pipe inhales the air and it makes the pressure inside

of the refrigerant cycle abnormally high. It may cause

explosion and injury.

The air in the indoor unit and in the pipe must be

evacuated. If air remains in the refrigerant pipes, it will

affect the compressor either reduce cooling/heating

capacity or lead to a malfunction. Refrigerant for air

purging is not charged in the outdoor unit. Use Vacuum

Pump as shown at the right figure.

1 Connect each assembly pipe to the appropriate valve

on the outdoor unit and tighten the flare nut.

2 Referring to the illustration below, tighten the flare

nut on section D first manually and then with a

torque wrench, applying the following torque.

B (Liquid)

3 Connect the charging hose of low pressure side of

manifold gauge to the packed valve having a service

port as shown at the figure.

(-76 cmHg) after about 10 minutes. This procedure

is very important to avoid a gas leak.

ŷ Turn off the vacuum pump.

ŷ Remove the hose of the low pressure side of

manifold gauge.

6 Open the stop valve of both liquid and gas sides.

7 Mount the valve stem nuts and the service port

cap to the valve, and tighten them at the torque of

NJIŷFPZLWKDWRUTXHZUHQFK

8 Check for gas leakage.

ŷ At this time, especially check for gas leakage from

the 3-way valve’s stem nuts(A port), and from the

service port cap.

CAUTION

ŷ Connect the indoor and outdoor units using pipes

with flared connections (not supplied). For the lines,

use insulated, unwelded, degreased and deoxidized

copper pipe, (Cu DHP type to ISO 1337 or UNI EN

12735-1), suitable for operating pressures of at least

4200 kPa and for a burst pressure of at least 20700

kPa. Copper pipe for hydro-sanitary applications is

completely unsuitable.

ŷ For sizing and limits (height difference, line length,

max. bends, refrigerant charge, etc.) see “Connecting

refrigerant pipe section”.

Step 9 Adding refrigerant (R-410A)

ŷ The outdoor unit is loaded with sufficient refrigerant

for the standard piping. Thus, refrigerant must be

added if the piping is lengthened. This operation

can only be performed by a qualified refrigeration

specialist. To determine the quantity of refrigerant

charge, see Calculating the quantity of refrigerant to

add on page 20.

1 Check if the stop valve is closed completely.

2 Charge the refrigerant through the service port of the

liquid stop valve.

NOTE

ŷ Do not charge the refrigerant through the service

port of the gas stop valve.

3 If you have any difficulty charging the refrigerant as

described in the steps above, take the following steps:

a Open the liquid stop valve and gas stop valve.

b Operate the air conditioner by pressing the K2

key on the outdoor unit PCB.

c After about 30 minutes, charge the refrigerant

through the service port of the gas stop valve.
