Installation Guideline

Installation of Outdoor Unit

• The outdoor unit must be installed in such a way, so as to prevent short circuit of the hot discharged air or obstruction to the smooth air ﬂ ow. Please follow the installation clearance shown in the ﬁ gures below. Select the coolest possible place where intake air temperature is not greater than the outside air temperature (maximum 45°C/113°F).

• Where a wall or other obstacle is in the path of outdoor unit’s intake or exhaust airﬂ ow, follow the installation guidelines below.

• For any of the below installation patterns, the wall height on the exhaust side should be 1200mm or less.

More than 100

• Before installing the piping and connecting cord, please remove the access panel and plastic valve cover for easy access. Refer to ﬁ gures shown below.

• There are 2 holes on the base of Outdoor Unit for condensed water to ﬂ ow out. Insert the drain elbow to one of the holes.

• To install the drain elbow, ﬁ rst insert one portion of the hook to the base (portion A), then pull the drain elbow in the direction shown by the arrow while inserting the other portion to the base. After installation, check to ensure that the drain elbow clings to base ﬁ rmly.

• If the unit is installed in a snowy and chilly area, condensed water may freeze in the base. In such case, please remove plug at the bottom of unit to smooth the drainage.

Caulk pipe hole gap with putty.

Cut thermal insulation pipe to an appropriate length and wrap it with tape, making sure that no gap is left in the insulation pipe's cut line.

Wrap the insulation pipe with the finishing tape from bottom to top.

• Before installing the unit, ensure that the power supply matches the power requirement of the air conditioner.

Installation of Indoor Unit

Service Space

Install the indoor unit at a location with the following requirements

• Location is suitable for wiring, piping and drainage.

• No obstruction of air ﬂ ow into and out of unit where cooler air can be evenly distributed.

• Ensure that air discharge is not short circuited with air intake.

• Ensure that wall is sufﬁ ciently strong, rigid, ﬂ at, perpendicular and vibration free.

• Where air ﬁ lter cassette can be slided in or out easily.

• Where there is no danger of ﬂ ammable gases.

• Where there is no direct sunlight on unit.

Preliminary Site Survey

• Electrical supply and installation is to conﬁ rm to local authority’s (e.g. National Electrical Board) codes and regulations.

• Voltage supply ﬂ uctuation must not exceed ± 10% of rated voltage. Electricity supply lines must be independent of welding transformers which can cause high supply ﬂ uctuation.

• Ensure that the location is convenient for wiring, piping and drainage.

• The indoor unit must be installed in such that free from any obstacles in path of cool air discharge and warm air return, and must allow spreading or air throughout the room (near the centre of the room).

• Clearance must be provided for the indoor unit from the wall and obstacles as shown in the ﬁ gure.

Beam

• The installation place must be strong enough to support a load of 4 times the indoor unit weight to avoid amplifying noise and vibration.

• The installation place (handling ceiling surface) must be level and the height in the ceiling is 350mm or more.

• The indoor unit must be away from heat and steam sources (avoid installing it near an entrance).

• Measure and mark the position for the hanging rod. Drill the hole for the angle nut on the ceiling and ﬁ x the hanging rod.

• The installation template is extended according to temperature and humidity. Check on dimensions in using.

• The dimensions of the installation template are same as those of the ceiling opening dimensions.

• Before ceiling laminating work is completed, be sure to ﬁ t the installation template to the indoor unit.

Note: Be sure to discuss the ceiling drilling work with the installers concerned.

• Conﬁ rm the pitch of the hanging rod is 770mm x 622mm sharp.

• Hold the unit and hand 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.

• Conﬁ rm with a level gauge that the unit is installed horizontally and tighten the nut and bolt to prevent unit falling and vibration.

• Open the ceiling board along the outer edge of the paper installation template.
