5. INDOOR UNIT INSTALLATION
As for the parts to be used for installation work, be sure to use
the provided accessories and specific Daikin parts.
(1) Level the indoor unit with the leveling screws (7). If
the floor is too uneven to level the unit, place the unit
on a flat surface and level it.
(2) If the unit is in danger of falling over, either fasten to
the wall using the holes provided, or fasten to the
floor with an optional floor fastener.
(3) The legs can be retracted if the indoor unit is to be
hung on a wall. To do so, lift the legs as shown in the
following figure.
NOTE
• Use the installation mount for installation. Check whether
the wall is strong enough to bear the weight of the unit or
not. If there is a risk, reinforce the wall before installing the
unit.
• The unit requires a minimum 2.5 inch clearance on the
underside for air intake. Ensure the unit is level when
installed so that drainage flows smoothly. If tilted or on an
incline, water can leak.
• Operating sound may be louder if installed on a more solid
wall.
(4) Perform the following procedure to mount the
optional remote controller on the unit if desired.
(FXLQ type only)
(5) Open the left side of control panel and mount the
lower case of the remote controller.
•
See the installation manual
attached to the remote control-
ler for instructions on fastening
screws and wiring the remote
controller.
NOTE
• Setting the unit at an angle opposite to the drain piping
might cause leaks.
6. REFRIGERANT PIPING WORK
For refrigerant piping of outdoor units, see the installa-
tion manual attached to the outdoor unit.
Execute heat insulation work completely on both sides of
the gas piping and the liquid piping. Otherwise, a water
leakage can result.
When using a heat pump, the temperature of the gas piping
can reach up to approximately 250°F, so use sufficiently resis-
tant insulation.
In cases where the temperature and humidity of the
refrigerant piping sections might exceed 86°F or RH80%,
reinforce the refrigerant insulation by 13/16” or thicker.
Condensate may form on the surface of the insulating
material.
Before refrigerant piping work, check which type of refrig-
erant is used. Proper operation is not possible if the types
of refrigerant are not the same.
NOTE
• Use a pipe cutter and flare suitable for the type of refrig-
erant.
• To prevent dust, moisture or other foreign matter from
infiltrating the tube, either pinch the end or cover it with
tape.
• Do not allow anything other than the designated refrig-
erant to get mixed into the refrigerant circuit, such as
air, etc.
• If any refrigerant gas leaks while working on the unit,
immediately ventilate the room.
When connecting refrigerant piping:
• Ensure that theoutdoor unit is charged with refrigerant.
• Use copper alloy seamless pipes.
• To prevent flare nut cracking and gas leaks, be sure to use
both a spanner and torque wrench together, as shown in
the drawing, when connecting or disconnecting pipes to /
from the unit.
• Refer to Table 2 for the dimensions of flare.
