Cassette Indoor Unit Installation; Indoor Unit Main Body Installation - Carrier 38MGQ Installation Instructions Manual

CASSETTE INDOOR UNIT INSTALLATION

Select install location of the indoor unit
1. Obstructions should be removed from the indoor unit's intake
or outlet vents so the air can flow throughout the room.
2. Make sure the installation is in accordance with the
requirements of the required clearances on the schematic
diagram.
3. Select a location that can withstand 4 times the weight of
the indoor unit and would not increase the operating noise.
4. Ensure the unit is level.
5. Select a location where condensated coagulated water can
drain easy connect easy with the outdoor unit.
6. Ensure there is enough space for care and maintenance.
Ensure the height between the indoor unit and ground is

3ft. (1mt) or 16ft (5mt).
7. When installing the steeve bolt, check if the install place can
withstand a weight 4 times of the unit's. If not, reinforce
before installation. Refer to the install cardboard to
determine where the location should be reinforced.
IMPORTANT: To guarantee the good performance, the unit must
be installed by professional personnel according to this instruction.

NOTE: Installation is possible with a ceiling dimension of 23.62
in. (600m) (marked with *). However to achieve a ceiling- -panel
overlapping dimension of 0.59in (15mm), the spacing between the
ceiling and the unit should be 0.79 in. (20mm) or less. If the
spacing between the ceiling and the unit is over 0.79 in. (20mm),
attach sealing material in the part or recover the ceiling.

INDOOR UNIT MAIN BODY INSTALLATION

Installation is possible with a ceiling dimension of 23.62 in.
(600mm) (marked with *). However, to achieve a ceiling- -panel
overlapping dimension of 0.59 in. (15 mm), the spacing between
the ceiling and the unit should be 0.79 in. (20mm or less). If the
spacing between ceiling and the unit is over 0.79 in. (20mm),
attach sealing material in the part or recover the ceiling.
1. Prepare the ceiling opening needed for installation where
applicable (for existing ceilings).
a. Create the ceiling opening required for installation. From
the side of the opening to the casing outlet, implement the
refrigerant and drain piping and wiring for the remote
controller (unnecessary for wireless type). Refer to each
piping or wiring section.
b. After creating an opening in the ceiling, it may be necessary
to reinforce the ceiling beams to keep the ceiling level and
to prevent it from vibrating. Consult the builder for details.
2. Install the installation hooks. Use either a M8 or M10 size
bolt.
a. Use expansible hooks, sunken anchors or other field
supplied parts to reinforce the ceiling in order to bear the
weight of the unit.
b. Adjust the clearance from the ceiling before proceeding
further. Installation example see Fig. 27.
