Installing The Refrigerant Piping - Trane 17 Series Installer's Manual

17 Series Mini-Split
If the outdoor unit is installed higher
than the indoor unit:
1. Taping should be done from the lower to the
upper part. Do not wrap too tightly to avoid
compression of the insulation, otherwise its
eff ectiveness is reduced.
2. All pipes are bound and taped together and
also should be trapped to prevent water
from returning to the room.
3. Secure all pipes to the wall with saddles.
Note: Oil traps are sometimes needed when
the outdoor unit is installed higher than the
indoor unit. An oil trap is needed for each 20 ft.
(6m) of vertical rise on the gas pipe.
