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 pipe flaring and
flare torque requirements, technique, etc.
1.
Based on the position of the wall hole relative to the
mounting plate, choose the side from which the piping
will exit the unit.
2. If the wall hole is behind the unit, keep the knock-out
panel in place. If the wall hole is to the side of the
indoor unit, remove the plastic knock-out panel from
that side of the unit. (See Fig. 3.3 ). This will create a
slot through which your piping can exit the unit. Use
needle nose pliers if the plastic panel is too difficult to
remove by hand.
3. Groove has been made in the knock-out panel in order
to cut it conveniently. The size of the slot is determined
by the diameter of piping.
4. Use scissors to cut down the length of the insulating
sleeve to reveal about 15cm (6in) of the refrigerant
piping. This serves two purposes:
• To facilitate the
Refrigerant Piping Connection
process
• To facilitate Gas Leak Checks and enable you to check
for dents
5. If existing connective piping is already embedded in
the wall, proceed directly to the
Connect Drain Hose
step. If there is no embedded piping, connect the
indoor unit’s refrigerant piping to the connective piping
that will join the indoor and outdoor units. Refer to the
Refrigerant Piping Connection
section of this manual
for detailed instructions.
6. Based on the position of the wall hole relative to the
mounting plate, determine the necessary angle of your
piping.
7. Grip the refrigerant piping at the base of the bend.
8. Slowly, with even pressure, bend the piping towards
the hole.
Do not
dent or damage the piping during the
process.
STEP 4: PREPARE REFRIGERANT PIPING
Be extremely careful not to dent or damage the piping while
bending them away from the unit. Any dents in the piping will
affect the unit’s performance.
CAUTION
NOTE ON PIPING ANGLE:
Refrigerant piping can exit the indoor
unit from four different angles:
• Left-hand side
• Left rear
• Right-hand side
• Right rear
