INTRODUCTION
Model FV4C Fan Coil units are designed for flexibility and can be
used for upflow, horizontal, or downflow (kits required on
manufactured and mobile home) applications. These units are
designed specifically for Puron
r
refrigerant (R--410A) and must be
used only with Puron air conditioners and heat pumps as shipped.
These units are designed to meet the low air leak requirements
currently in effect. Because of this, the units need special attention
in the condensate pan and drain connection area and when brazing
tubing.
These units are available for application in systems of 18,000
through
60,000
Btuh
nominal
cooling
capacities.
Factory--authorized, field--installed electric heater packages are
available in 5 through 30 kW. See Product Data for available
accessory kits.
INSTALLATION
Procedure 1 — CHECK EQUIPMENT
Unpack unit and move to final location. Remove carton taking care
not to damage unit.
Inspect equipment for damage prior to installation. File claim with
shipping company if shipment is damaged or incomplete. Locate
unit rating plate which contains proper installation information.
Check rating plate to be sure unit matches job specifications.
Procedure 2 — MOUNT FAN COIL
Unit can stand or lie on floor, or hang from ceiling or wall. Allow
space for wiring, piping, and servicing unit.
IMPORTANT
: When unit is installed over a finished ceiling
and/or living area, building codes may require a field--supplied
secondary condensate pan to be installed under the entire unit.
Some localities may allow the alternative of running a separate,
secondary condensate line. Consult local codes for additional
restrictions or precautions.
When installing any fan coil over a finished ceiling and/or living
area, installation of a secondary drain pan under entire unit to avoid
damage to ceiling is recommended.
FV4C Fan Coils can be installed for upflow and horizontal--left
applications as factory shipped. Units can be installed for
horizontal--right applications with field modifications. Units may
be converted for downflow applications using factory--authorized
accessory kits.
NOTE
: To ensure proper drainage for horizontal installations, unit
must be installed so it is within 1/8 in. (3.2mm) level of the length
and width of unit.
A. Upflow Installation
If return air is to be ducted, install duct flush with floor. Set unit on
floor over opening. Only use return--air opening provided. All
return air must pass through the coil. (See Fig. 2.)
