Installation

Drywall Installation

The fan coil model series “FSG” has a cabinet  which  is  

designed  to be furred-in. Drywall can be directly attached to 

the cabinet or the unit can be framed.

Direct Application

 – The hinged air panel must be used. It 

is designed to fit the ½" drywall flange around the return air / 

access opening on the unit. Use drywall screws no longer than 

1¼" and follow the instructions on the page in the submittals 

which shows where the screws can be located to avoid 

damaging internal components. When using the hinged panel, 

drywall must be attached to the front. The sides and back can 

be framed.

Framing 

– Frame the unit using metal studs. The flange 

around the return air/access opening is 2" deep. The type of 

return air panel which has a hinged filter door in its upper half 

is used with this type of installation. It is preferable that the stud 

does not touch the fan coil cabinet so that any slight vibration 

which may exist is not transferred to the stud.
Before installing the thermostat and grilles, the walls must 

be painted. Instruct the  painter not to spray over the labels 

on the unit. After installation, dust must be vacuumed from 

the coil surfaces, the drain pan, the motor windings and the 

cabinet insulation.

Ducted Units

Remove the supply air opening knock-out in the top panel of 

the fan coil. Cut out the cabinet insulation from the opening 

and butter the cut edge if it is glass fiber insulation. Attach the 

supply air duct.

NOTE: 

Supply air duct flanges are not provided by the 

factory.

Electrical Connection

The unit has a single point connection at the junction box 

inside the unit. It might also have a disconnect switch 

and/or a fuse. All electrical wiring must be in accordance 

with the current version of the national and local codes. A 

qualified electrician must carry out the work. The junction 

box is located behind the fan/motor shield. Electrical power 

to the unit should be disconnected by opening the remote 

disconnect device prior to removing the fan/motor shield. 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

Remove the hinged door by raising to the horizontal position 

and gently pull out past the hinge pins. Place the return air 

panel in place and align the pre-drilled holes and secure using 

4 sheet metal screws. Re-install the hinged filter access door 

using the same technique used to remove it. 

Thermostat Installation

 CAUTION

Adjusting fan RPM to a higher speed may result in excessive air flow noise. 

Unit mounted thermostat

 – Connect the wires from the 

thermostat to the wire harness usually inside the electrical box 

using the plug provided. 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.

Remote mounted thermostat

 – Run low voltage wires from 

the 24V thermostat on the wall back to the terminal strip 

inside the unit.
The thermostat must have a 0-10VDC fan speed control signal 

to control the fan. A motor speed board model SPDM will allow 

the contractor to adjust the maximum fan speed if the factory 

set point is not suitable. If the thermostat has a 3 speed fan 

control, the digital to analog interface board, EVO board model 

EVO/10Y-4Spd must be used. This board has max RPM 

adjustment pots where the CFM can be adjusted for each spd 

if factory settings are not suitable.
