Preparations Before Installation - Daikin FXZQ20MVE Installation Manual

4. PREPARATIONS BEFORE INSTALLATION

(1) Relation of ceiling opening to unit and suspension bolt position.
533 (Suspension bolt pitch)
575 (indoor unit)
585-660 (Ceiling opening)
700 (Decoration panel)
NOTE
• Installation is possible with a ceiling dimension of 660 mm (marked with *). However, to achieve a ceiling-
panel overlapping dimension of 20 mm, the spacing between the ceiling and the unit should be 45 mm or
less. If the spacing between ceiling and the unit is over 45 mm, attach ceiling material to
the ceiling.
(2) Make the ceiling opening needed for installation where applicable. (For existing ceilings)
• Refer to the paper pattern for installation (5) for ceiling opening dimensions.
• Create the ceiling opening required for installation. From the side of the opening to the casing out-
let,implement the refrigerant and drain piping and wiring for remote controller (unnecessary for wire-
less type) and wiring between units. Refer to each PIPING or WIRING section.
• After making an opening in the ceiling, it may be necessary to reinforce ceiling beams to keep the ceil-
ing level and to prevent it from vibrating. Consult the builder for details.
(3) Install the suspension bolts.
~
(Use either a M8 M10 size bolt) Use a hole-in
anchor for existing ceilings, and a sunken insert,
sunken anchor or other field supplied parts for new
ceilings to reinforce the ceiling to bear the weight of
the unit.
Adjust clearance (50
before proceeding further.
NOTE
• All the above parts are field supplied.
