INSTALLATION INSTRUCTIONS:

Vertical Basic Fan Coil Series

VBC, VBF, VBA, VBL

INSTALLER MUST BE A TRAINED, EXPERIENCED SERVICE

TECHNICIAN

1. PRESSURE CHECK

The complete unit including coil, valve package and associated piping is shipped

pressurized. Use the air valve to release the pressure. Should there be no pressure,
inspect the unit for possible shipping damage. The unit must be pressure tested again
prior to installation.

2. MOUNTING

2.1 The unit is to be located on a leveled surface at the designated location against a wall
or a solid partition. When leveling legs (optional) are supplied, these are located
under the unit’s legs (2 per leg). Turn the bolts as required until the unit is perfectly
level to ensure proper condensate drainage.

2.2 Once leveled and connected, the unit should be bolted to the back wall in such a
manner that will prevent tip-over. Exception: Due to its wider base, the VBC does not
have to be bolted to the back wall.

3. PIPING

3.1 All piping leading to the unit must be adequately supported to prevent excessive stress
on the unit’s piping. However, sufficient free movement is required for thermal
expansion/contraction.

3.2 Do NOT over-tighten threaded connections.

3.3 Do NOT overheat sweat connection. Use solder (95/5) with a m elting temperature
below 600oF.

3.4 When the valve package is supplied separately for field installation, carefully follow
the schematic piping diagram and installation instructions provided with the package.

3.5 All pipes and fittings that extend beyond the drain pan MUST be insulated.

3.6 The inlet and outlet points are clearly marked on the unit’s piping. Depending upon
the field piping layout, the connecting inlet, outlet and condensate piping could be
routed from the back of the unit or from the bottom.

4. OUTSIDE AIR DAMPER (OPTIONAL) – VBC, VBF, VBA ONLY

4.1 Outside Air Duct Connection

The unit is provided with an outside air intake opening at the back which leads to the

built-in outside air damper. The installing contractor should build a duct to match the
size of the opening. This duct should be connected via a duct collar to the unit, on one
side, and to an outside weather louver on the outside wall. This installation does not
form part of the unit supply.

4.2 Damper Setting

The factory setting is for the damper to fully open when energized. However, should a

smaller quantity of outside air be required, the degree of opening of the damper blade

can be adjusted as follows:

4.2.1 Remove the front panel of the unit and remove the filter.

4.2.2 Open the Wing-nuts securing the outside air damper assembly and slide it out to gain
the better access.

4.2.3 Energize the motor until damper is in the fully open position.

4.2.4 While in the fully open position, loosen the set screw holding the damper shaft to

the damper motor.

4.2.5 Adjust the position of the blade to the desired angle and tighten the set screw.

4.2.6 Reassemble the unit.
