Step 7: Wrap Piping And Cables; Step 8: Mount Indoor Unit - Mirage IVEH121A Owner's Manual

6. Feed the signal wire through this slot, from the
back of the unit to the front.
7. Facing the front of the unit, match the wire col-
ors with the labels on the terminal block, connect
the u-lug and and firmly screw each wire to its
corresponding terminal.
CAUTION
DO NOT MIX UP LIVE AND NULL WIRES
This is dangerous, and can cause the air
conditioning unit to malfunction.
8. After checking to make sure every connection
is secure, use the cable clamp to fasten the
signal cable to the unit. Screw the cable clamp
down tightly.
9. Replace the wire cover on the front of the unit,
and the plastic panel on the back.
NOTE ABOUT WIRING
THE WIRING CONNECTION PROCESS MAY
DIFFER SLIGHTLY BETWEEN UNITS

Step 7: Wrap piping and cables

Before passing the piping, drain hose, and the
signal cable through the wall hole, you must bun-
dle them together to save space, protect them,
and insulate them.
1. Bundle the drain hose, refrigerant pipes, and
signal cable according to Fig. 3.10
DRAIN HOSE MUST BE ON BOTTOM
Make sure that the drain hose is at the bot-
tom of the bundle. Putting the drain hose at
the top of the bundle can cause the drain
pan to overflow, which can lead to fire or
water damage.
DO NOT INTERTWINE SIGNAL CABLE
WITH OTHER WIRES
While bundling these items together, do not
intertwine or cross the signal cable with any
other wiring.
2. Using adhesive vinyl tape, attach the drain
hose to the underside of the refrigerant pipes.
3. Using insulation tape, wrap the signal wire,
refrigerant pipes, and drain hose tightly together.
Double-check that all items are bundled in accor-
dance with Fig. 3.10
DO NOT WRAP ENDS OF PIPING
When wrapping the bundle, keep the ends of
the piping unwrapped. You need to access
them to test for leaks at the end of the instal-
lation process (refer to Electrical Checks and
Leak Checks section of this manual).

Step 8: Mount indoor unit

If you installed new connective piping to the
outdoor unit, do the following:
1. If you have already passed the refrigerant
piping through the hole in the wall, proceed to
Step 4.
2. Otherwise, double-check that the ends of the
refrigerant pipes are sealed to prevent dirt or
foreign materials from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant
pipes, drain hose, and signal wire through the
hole in the wall.
4. Hook the top of the indoor unit on the upper
hook of the mounting plate.
5. Check that unit is hooked firmly on mount-
ing by applying slight pressure to the left and
right-hand sides of the unit. The unit should not
jiggle or shift.
6. Using even pressure, push down on the
bottom half of the unit. Keep pushing down
until the unit snaps onto the hooks along the
3.10
bottom of the mounting plate.
7. Again, check that the unit is firmly mounted
by applying slight pressure to the left and the
right-hand sides of the unit.
