INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
***** WARNING TO INSTALLER, SERVICE PERSONNEL AND OWNER *****
Altering the product or replacing parts with non authorized factory parts voids all warranty or implied war-
ranty and may result in adverse operational performance and/or a possible hazardous safety condition to
service personnel and occupants. Company employees and/or contractors are not authorized to waive this
warning.
GENERAL
The manufacturer assumes no responsibility for equipment
installed in violation of any code requirement.
These instructions give information relative to the installation
of these fan coil units only. For other related equipment refer to
the proper instructions.
Material in this shipment has been inspected at the factory and
released to the transportation agency in good condition. When
received, a visual inspection of all cartons should be made
immediately. Any evidence of rough handling or apparent
damage should be noted on the delivery receipt and the material
inspected in the presence of the carriers representative. If
damage is found, a claim should be filed against the carrier
immediately.
PRE-INSTALLATION CONSIDERATIONS
1) Determine location for mounting the unit to insure best air
circulation within the room.
2) Determine proper cabinet orientation. (See below.)
3) Determine routing of water lines and electrical service to
unit.
DETERMINATION OF RIGHT-HAND / LEFT-HAND REFERENCES
1) Right-hand / Left-hand determination is based on looking at
the fan coil unit from the front.
2) Right-hand units have the thermostat / control box on the
left-hand side and the coil / valve connections and drain
pan are on the right-hand side.
3) Left-hand units have the thermostat / control box on the
right-hand side and the coil / valve connections and drain
pan are on the left-hand side.
The installer must adhere strictly to all local and national code
requirements pertaining to the installation of this equipment.
These units are designed to be installed vertically with zero
clearance to combustible materials.
****** WARNING ******
Unit must not be operated during building construction due to excessive airborne dust and debris. The units must not be operated under any
circumstances without the front panel or an air
filter in place.
4) A condensate line will need to be routed to an open drain
trap.
5) Location of unit must be in an area providing adequate
access to the unit since all components must be serviced
from the front of the unit.

1) Mounting location must allow enough clearance to permit
removal of cabinet panels.
2) After selecting the location for the unit, remove the front
panel. The front panel must be removed on the VS or VF unit
to gain access to the coil, drain connections and electrical
junction box. To accomplish this, pull firmly on the lower
cabinet door (each side) (Figure 1) until the cabinet releases
from its friction fastener. Proceed to lift the door assembly
straight up and off the cabinet frame.
Figure 1
3) Position the unit in its permanent location, making sure it
is level to insure proper drainage and operation, and secure
the unit in place. Two 1/2 inch holes have been provided on
each end of the unit for securing the unit to the wall along
with two 5/16 inch holes on each end of the cabinet frame to
secure cabinet frame to wall. It is recommended that all
mounting holes be used for proper installation. (Figure 2)

4) Note the 1-1/2" x 4-1/2" indentation in the plastic drain pan
(Figure 3). This area is provided for the supply and return
runouts if they are brought up from below the pan. All piping
must be well insulated to prevent sweating. There is a 0.84"
OD condensate drain connection on the secondary drain
pan suitable to receive a standard 3/4" PVC coupling / elbow.
Remove or cover the secondary drain pan before soldering the supply and return coil connections as hot solder
or the torch flame may damage the pan.
5) Solder the 5/8" coil connections in accordance with local
codes and regulations.
6) After coil connections have been made, check for leaks and
bleed the air from the system by venting each coil. (Figure 4)
