Application Information
Unit Installation
• 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.
FWKE
Unit Hanging
• 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 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 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 dripping inside the room.
