Application Information
Drain Test
• Connect the main drain pipe to the flexible drain.
• Feed water from flexible drain hose to check the piping for leakage.
• When the test is completed, connect the flexible drain hose to the drain connector on the indoor unit.
NOTE
This Indoor Unit uses a drain pump for condensed water drainage. Install the unit horizontally to prevent
water leakage or condensation around the air outlet.
Model: FWE05/06/07E
Standard Mounting
• Ensure that the overhead supports are strong enough to hold the weight of the unit.
• Position the hanger rods (wall mounting bracket for floor standing), and check for its alignment with the
unit.
• Also, check that the hangers are secured and the base of the fan coil unit is leveled in both horizontal
directions, taking into account the gradient for drainage flow as recommended in Figure A.
Please ensure that the following steps are taken:
• Check the gradient for drainage flow as recommended in Figure A.
• Provide clearance for easy servicing and optimal air flow as shown in Figure B.
• The indoor unit must be installed such that there is no short circuit of the cool discharge air with the warm
return air.
• Do not install the indoor unit where there is direct sunlight shining on the unit. The location should be
suitable for piping and drainage installation. The unit must be a large distance away from the door.
