Refrigerating connections
Keep sealed all open extremities of the
pipes with a cap until the connection is
completed. Be sure not to let anything in
the pipes or in the system, such as dirt,
water, etc.
The piping connected to the indoor and
outdoor unit must be new. Required
thickness of pipes is 0.8 mm or more.
Only use R32 refrigerant in line woith the
one already loaded in the outdoor unit to
fill the refrigerant in the system.
Additional charge of refrigerant and oil
If the length of the connecting pipe is
increased by 10 m compared to the
standard length, add 5 ml of refrigerant
oil for every 5 m of pipe added.
Method for calculating the amount of
additional refrigerant charge (liquid pipe):
amount of additional refrigerant charge =
additional length of pipe liquid x amount
of additional refrigerant charge per meter.
Use equipment and connecting pipes
suitable for R32 refrigerator.
