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.
All units are safety agency listed (see unit label) for installation with zero inches
clearance to combustible materials. This includes the unit cabinet, discharge
plenum and connecting ducts.
The unit is designed for free return installation (non-ducted return air),
therefore 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 panel and to provide access to electrical and plumbing controls.
NOTE: 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 that the fan coils are securely mounted and the
structure is sufficient to support the weight of the equipment. All anchors for
mounting the equipment must be placed and sized to ensure a safe and
durable installation.
