N.B.: add lubricating oil equivalent to 10 % of the weight of the gas calculated only for the refrigerant connection lines between indoor and outdoor
unit. The type of oil in use is FV50S.
The DROUD outdoor unit is pre-charged with refrigerant to meet the needs of the indoor unit, the outdoor unit and up to 5 m of interconnecting pipe
work. Longer pipe work separations may require additional refrigeration and oil.

8.4.4 Connecting refrigerating circuit
•
Connect the on-site pipe system to the liquid and suction line. The precise positions
of the connections can be determined from the order-specific dimensional drawing
of the unit.
Routing refrigerant lines
•
Pipes should always be routed with a slight slope to the flow direction.
•
This favors a return transport of the refrigerant oil to the compressor. The refrigerant
flows as a liquid through the liquid line (thinner tube) to the evaporator and then once
again as a gas through the insulated suction line back to the compressor.
•
Observe temperature-related changes in length!

Notice!
Dimensions of pipe connections on the unit are not decisive for the refrigerant lines
to be routed.
Notice!
When routing the pipes, always make sure that the pipe ends are sealed. Even if
the unit setup is incomplete, seal all pipe ends after the job is finished. Only this way
can penetration of dirt and humidity be prevented.
