Installation Of The Indoor Unit - Daikin FWC07AATNMV1 Installationsaleitung

1. Preliminary Site Survey
Obstacle
• Electrical supply and installation is to conform to local authority's (e.g. National Electrical Board) codes and regulations.
• Voltage supply fluctuation must not exceed ±10% of rated voltage. Electricity supply lines must be independent of welding
transformers which can cause high supply fluctuation.
• Ensure that the location is convenient for wiring, piping and drainage.
• The indoor unit must be installed in such that is 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)
• Provide clearance for the indoor unit from the wall and obstacles as shown in the figure.
• The installation place must be strong enough to support a load 4 times the indoor unit weight to avoid amplifying noise and
vibration.
• The installation place (hanging ceiling surface) must be levelled 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).
2. Unit Installation
890.0 mm (Ceiling Board Opening)
790.0 mm (Hanging Rod)
• Measure and mark the position for the hanging rod. Drill the
hole for the angle nut on the ceiling and fix 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 fit
the installation template to the indoor unit.
Note: Be sure to discuss the ceiling drilling work with the
installers concerned.

water flow.
• 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 flexible 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

• Confirm the pitch of the hanging rod.
• 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.
• Confirm 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
