2. Use the holder at the back of the unit to
prop up the unit, giving you enough room
to connect the refrigerant piping, signal cable,
and drain hose.
Use the holder at the back
of the unit against on the
mounting plate to prop up
the unit
Step 3. Connect drain hose and refrigerant
piping (refer to Refrigerant Piping Connection
section of this manual for instructions).
Step 4. Keep pipe connection point exposed to
perform the leak test (refer to Electrical Checks
and Leak Checks section of this manual).
Step 5. After the leak test, wrap the connection
point with insulation tape.
Step 6. Remove the bracket or wedge that is
propping with insulation tape.
Step 7. Using even pressure, push down on the
bottom half of the unit. Keep pushing down
until the unit snaps onto the hooks along the
bottom of the mounting plate.
If there is no refrigerant piping embedded in
the wall, do the following:
Based on the position of the wall hole relative
1.
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 figure below). 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.
If need to cut the big size plastic
panel, cut as shown above.
3. Use scissors to cut down the length of the
insulating sleeve to reveal about 40mm (1.57in)
of the refrigerant piping. This serves two purposes:
• To facilitate the Refrigerant Piping
Connection process.
• To facilitage Gas Leak Checks and enable
you to check for dents
4. Use the holder at the back of the unit to
prop up the unit, giving you enough room
to connect the refrigerant piping, signal cable,
and drain hose.
5. 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.
