the remote disconnect device prior to removing the fan/motor shield. Do not use the motor speed
switch as a disconnect method. All wiring must enter the unit through designated openings and not
through the riser stub out openings.
Supply Air Grille Installation
The grille is a snap-in fit into the collar on the unit. If the unit has a ducted supply, side supply air grilles
are provided with a balancing damper. If the unit has two unit mounted grilles and is not ducted,
one of the grilles is provided with a damper. This grille is to be fitted to the opening which requires
the lesser of the two air flows (for example the bedroom).
Return Air/Access Panel Installation
Type with quarter turn fasteners:
1.
Insert the square shaft of the fastener into the recessed hole in the panel. Put the plastic
washer onto the shaft, followed by the retainer. Push the retainer as far as possible so that it
firmly holds the fastener in place.
2.
Put the pawl onto the shaft and position it so that the pawl will pull the panel tightly against
the wall. Tighten the lock screw in the pawl.
3.
Install the filter in the panel, hook the panel over the bottom collar of the fan coil unit, rotate
the panel upright so that it is against the wall and turn the head of the fastener clockwise to
the locked position.
Type with a hinged filter door in the upper half of the grille panel:
1.
If the drywall has not been installed flush with the outer edge of the collar on the unit and if a
gap exceeding ½” exists between the inner surface of the drywall and the outer edge of the
collar, the opening will have to be sleeved.
2.
Insert the grille panel into the 2” deep collar on the unit so that the grille frame is against the
drywall.
3.
Lift the hinged filter door to the horizontal position and secure the grille panel by driving two
sheet metal screws through the inside of the grille frame and into the collar on the unit. Do
not over-tighten the screws as this can distort the frame.
4.
Install the filter into the channels behind the grille and close the filter access door.
Thermostat Installation
1.
Unit mounted thermostat
– Connect the wires from the thermostat to the wire harness
usually inside the electrical box using the plug provided or wire nuts. Fit the thermostat onto
the electrical box using the machine screws provided. The electrical box is located on the
front of the unit, above the return air panel.
2.
Remote mounted thermostat
– Run low voltage wires from the 24V thermostat on the wall
back to the terminal strip inside the unit.
