10.2 Planning the Coolant Return

The coolant circuit contains a special oil to lubricate the

outdoor unit compressor. To assist the return of the oil

to the compressor the following is recommended:

- that the indoor unit is located higher than the outdoor

unit and,

- that the suction pipe (the thickest one) is assembled

with the tilt towards the compressor.

If the outdoor unit is mounted higher than the indoor

unit, the suction pipe must be mounted in a vertical

position. At heights exceeding 7.5 m:

• An additional oil deposit should be installed at each

7.5 m interval to collect the oil and suction it, returning

it to the outdoor unit and

• An elbow can be installed in front of the outdoor unit

to further assist the oil return.

10.3 Connection of the Coolant Pipes

Note!

Installation is easier if the gas suction pipe is

connected up first. The suction pipe is the

thickest one.

• Mount the outdoor unit in the designated site.

• Remove the protection hoods from the coolant joints

in the outdoor unit.

• Carefully bend the installed pipe towards the outdoor

unit.

Warning!

Danger of breakdowns or malfunction. Danger of

wear in the coolant pipes.

Bend the pipe carefully to prevent choking or

breaks.

• Cut the pipes, leaving enough extra piping hanging

over to enable the unit to be hooked up at the outdoor

unit joins.

• Flare the coolant pipe when installed.

• Join the coolant pipes to the corresponding outdoor

unit connection.

• Insulate the coolant piping correctly and separately.

To do so, cover any possible cuts with masking tape or

insulate any bare coolant piping with the

corresponding insulation material used for cooling.
