Reduction in capacity VS increase in pipe length
NOTES
1. The copper pipes must be installed level in both the horizontal and vertical
plane.
2. If actual distance above or below condenser exceeds 3 meters make a loop.
3. If actual piping length exceeds 5 meters add refrigerant 25 grams per meter
for sizes 9, 12, or until system pressures are balanced.
4. Performance reduction data is based on 10 meters height difference between
indoor and outdoor unit at standard test temperature conditions.

Piping
Outdoor unit piping is connected after the indoor unit has been
installed.
1. For indoor unit piping, please use 2 spanners. The small
connection should not be overly tightened as it will result in
deformation. Always use spanners with torque limitation.
2. First place the tapered side onto the tapered connection, use
your hand to turn the tapered pipe to the end, then using the
spanner to secure tightly.
3. Refer to table below for recommended details.
Torques for tapered washers
