Fig. 14 - Fan Coil Unit Mounting Methods

(hardware is field-supplied)

c.Drill holes for routing refrigerant lines, condensate line and electrical and control connections.

d.Lift the unit into place, and fit the hex-head bolts on sides of indoor unit into mounting slots of mounting brackets. Ensure unit is mounted with a slight tilt to the rear side for proper drainage.

e.Tighten indoor unit hex-head bolts securely.

INSTALL OUTDOOR UNIT

The outdoor units can be installed on the ground, on the roof, or mounted on a wall.

NOTE: Install the unit so that the coil does not face into prevailing winds. If this is not possible and constant wind winds above 25 mph are expected, use accessory wind baffle. See installation instructions provided with accessory kit. Wind baffles should also be used on all units with accessory low ambient temperature control.

Mounting on Ground

1.Mount unit on a solid level concrete pad.

2.If a heat pump is being installed, use a field- provided snow stand or ice rack where prolonged subfreezing temperatures or heavy snow occurs.

3.Position unit so water or ice from roof does not fall directly onto unit.

4.On cooling only units, an accessory stacking kit can be used when units are to be stacked. See installation instructions provided with the accessory kit.
