Application Information
Indoor Installation
Model: AWM-JW
The indoor unit must be installed in such a way so as to prevent short circuit of the cool discharged air with
the hot return air. Please follow the installation clearance shown in the gure. Do not place the indoor unit
where there could be direct sunlight shining on it. Also, this location must be suitable for piping and drainage,
and be away from doors or windows.

Air Purging
To prevent pump damage, the fan coil unit should not be energized until the coil and all water lines have
been purged of air.
The Air Vent located inside the casing. Removed the casing and connect hose to the air vent while doing
purging.
Ensure there is no water droplets go into the control box during purging process.
The water piping can be routed to the unit in a number of ways (left or right from the back of the unit), by
using the cut-out holes on the casing of the unit (see gure). Bend the pipes carefully to the required position
in order to align it with the holes. For the side and bottom, hold the bottom of the piping and then position it to
the required direction (see gure). The condensation drain hose can be taped to the pipes.

Application Information
Mounting Installation Plate
Ensure that the wall is strong enough to withstand the weight of the unit. Otherwise, it is necessary to
reinforce the wall with plates, beams or pillars.
Use the level gauge for horizontal mounting, and x it with 5 suitable screws for AWM07/10/15JW and 7
suitable screws for AWM20/25JW.
In case the rear piping draws out, drill a hole 65mm in diameter with a cone drill, slightly lower on the outside
wall (see gure).

1. Preliminary Site Survey
Be sure to read this manual before installing the air-conditioner indoor unit.
• Voltage supply uctuation must not exceed +10% of rated voltage. Electricity supply lines must be
independent of welding transformers which can cause high supply uctuation.
• Ensure that the location is convenient for wiring, piping and drainage.
• Do not exert pressure on the resin parts when opening the unit or when moving it after opening.
• Do not move the unit from packaging while moving, until it reaches the installation site. Use safe material
or protection plates when unpacking it or lifting it to avoid damage or scratches to the unit.

• Ensure a location where:
a) Drainage can be done easily.
b) Convenient for wiring and piping.
c) Which have enough space for installation and service work.
d) Where no risk of ammable gas leakage.
e) When free from any obstacles in path of cool air discharge and warm air return and must allow
spreading of air throughout the room (near the center of the room).
f) Must be provided clearance for indoor unit from the wall and obstacles as shown in gure below.
g) The installation place must be strong enough to support a load 4 times the indoor unit weight to avoid
amplifying noise and vibration.
h) The installation place (hanging ceiling surface) must be assuring levelness and the height in the ceiling
is 350mm or more.
i) The indoor unit must be away from heat and steam sources (avoid installing it near an entrance).

Application Information
Unit Installation
• Measure and mark the position for the hanging rod. Drill the hole for the angle nut on the ceiling and x the
hanging rod.
• The installation template is extended according to temperature and humidity. Check on dimensions in use.
• The dimensions of the installation template are the same as those of the ceiling opening dimensions.
• Before ceiling laminating work is completed, be sure to t the installation template to the indoor unit.
NOTE
Be sure to discuss the ceiling drilling work with the installers concerned.

• Hold the unit and hang it on the hanging rod with the nut and washer.
• Adjust the unit height to 35.0mm between the indoor unit bottom surface and the ceiling surface.
• Conrm with a level gauge that the unit is installed horizontally and tighten the nut and bolt to prevent unit
failing and vibration.
• Open the ceiling board along the outer edge of the paper installation template.

Drain Piping Work
• Drain pipe must be in downward gradient for smooth drainage.
• Avoid installing the drain pipe in up and down slope to prevent reversed water ow.
• During the drain pipe connection, be careful not to exert extra force on the drain connector at indoor unit.
• The outside diameter of the drain connection at the exible drain hose is 20mm.
• Be sure to execute heat insulation (polyethylene foam with thickness more than 8.0mm) on the drain
piping to avoid the condensed water dripping inside the room.
