Preparations Before Installation - Daikin FXMQ07PVJU Installation Manual

CAUTION
• Install the indoor and outdoor units, power supply wiring and
connecting wires at least 3.3 ft away from televisions or radios
in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.3 ft may not
be sufficient enough to eliminate the noise.)
• In the case of the installation of a wireless remote controller, the
transmission distance of the wireless remote controller may be
shortened if the room has a fluorescent light of electronic light-
ing type (i.e., an inverter or rapid-start fluorescent light).
Keep the distance between the receiver and the fluorescent
light as far as possible.
(2) Use hanging bolts to install the indoor unit. Check that the
place of installation withstands the weight of the indoor unit.
Secure the hanging bolts with proper beams if necessary.

PREPARATIONS BEFORE INSTALLATION

(1) Check the positional relationship between the ceiling open-
ing hole and the hanging bolt of the unit.

purposes of the control box and drain pump, prepare one
of the following service spaces.
1. Inspection hatch 1 (17-3/4 × 17-3/4) for the control
box and a minimum space of 12 in. for the lower part
of the product. (Refer to Fig. 2-2)
2. Inspection hatch 1 (17-3/4 × 17-3/4) for the control
