CAUTION
Dents in the piping will affect performance. If you dent or damage the piping, cease
manipulation immediately and contact MRCOOL technical support at [phone].
Be extremely careful not to dent or damage the piping while bending them away from the unit.

Keep in mind that the hooks on the mounting
plate are smaller than the holes on the back
of the unit. If you find that you don’t have
ample room to connect embedded pipes to
the indoor unit, the unit can be adjusted left
or right by about 30-50mm (1.25-1.95in),
depending on the model.

Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating sleeve
attached to the back of the unit. You must prepare
the piping before passing it through the hole in the
wall. Refer to the Refrigerant Piping Connection
section of this manual for detailed instructions on
torque requirements, technique, etc.
1. The piping will exit the unit from the right size of
the air handler.
2. Connect the indoor refrigerant piping to the
connective piping that will join the indoor and
outdoor units.
3. Based on the position of the wall hole relative to
the mounting plate, determine the necessary angle
of your piping.
4. Grip the refrigerant piping at the base of the bend.
5. Slowly, with even pressure, bend the piping
towards the hole. DO NOT dent or damage the
piping during the process.
NOTE ON PIPING ANGLE
Refrigerant piping should exit the indoor
unit from the right-hand side:
