Installation, Operation, and Maintenance Instructions
FAN COIL UNIT
The installer must adhere strictly to all local and national code requirements
pertaining to the installation of this equipment. These units are designed for
installation in a horizontal position above a dropped ceiling. All units are
designed for indoor use only, and are agency listed for installation with zero
clearance to combustible materials. This includes the fan coil cabinet,
discharge plenum and connecting ducts.
Free return installation (non-ducted return air): The furred down area must be
completely sealed (except return air grille) to ensure that all return air is pulled
from the conditioned space and not from other areas of the building structure.
Access must be provided for servicing the unit. If this access is provided by a
removable ceiling panel, ample space must be allowed for removal of the
blower panels and to provide access to electrical and plumbing controls.
When required, the unit can be tilted toward the drain nipple to ensure proper
drainage.
NOTES:
•
A field-fabricated secondary drain pan, with a drain pipe routed to the
outside of the building, may be required in installations over a finished
living space or in any area that may be damaged by water overflow from
the main drain pan. In some localities local codes may require a secondary
drain pan for any horizontal installation.
•
If a condensate overflow shut off switch, that is designed to be installed in
the drain line, is used in place of a secondary drain line then place it in the
primary drain line between the fan coil and the P-trap.
MOUNTING
It is important to ensure fan coils are securely mounted and the structure is
sufficient to support the weight of the equipment. All anchors for mounting
equipment must be placed and sized to ensure a safe and durable installation.
These units are provided with six (6) mounting slots. Metal washers and nuts of
the proper size are to be provided by the installer. When necessary, use shims
to obtain the proper level to ensure condensate will drain from the unit.
If mounting to wooden joists, use as a minimum 1/4” x 2” wood screws fully
engaged with fender washers for securing this unit to the structure.
