During and after installation, special care must be taken
to prevent foreign material such as paint, plaster, and
drywall dust from being deposited in the drain pan or
on the motor or blower wheels. Failure to do so may
have serious adverse effects on unit operation and in
the case of the motor and blower assembly, may result
in immediate or premature failure. All manufacturers’
warranties are void if foreign material is allowed to be
deposited on the motor or blower wheels of any unit.
Some units and/or job conditions may require some form
of temporary covering during construction.
While the manufacturer does not become involved
in the design and selection of support methods and
components, it should be noted that unacceptable
system operating characteristics and/or performance
might result from improper or inadequate unit structural
support. In addition, adequate clearance must be
provided for service and removal of the equipment and
its accessory components. Anchoring the equipment in
place is accomplished by using the mounting points
provided and positioning the unit to maintain the unit
on a LEVEL plane. The drain pan is internally sloped
toward the outlet connection. Care must be taken to
insure that the unit drain pan does not slope away from
the outlet connection. All units are supplied with hanger
brackets with rubber grommet isolators and brass inserts
for use with 3/8” all thread hanger rod.
The unit’s drain pan is factory sloped
toward the drain connection when the
unit is installed level and plumb.
Drain Pan
Standard drain pans are externally insulated, single wall
galvanized steel and can be equipped with a secondary
drain connection. The HL drain pan is easily removable
for cleaning or reversing connections. Auxiliary drip
pan to catch condensed moisture from valves and piping
must be sloped toward the drain pan.
Coils
All fan coils are available in 2 or 4 pipe configurations.
Heating coils are available in reheat or preheat position.
Heating and cooling coils are available with right, left
or opposite side connections.
Verify that the proper types of service are actually
provided to the unit. On units with steam heating
coils, the maximum steam pressure applied to the unit
should never exceed 15 PSIG. The drain piping and
steam trap should be sized and routed to allow for
proper condensate flow. The electrical service to the
unit should be compared to the unit nameplate to verify
compatibility. The routing and sizing of all piping, and
the type and sizing of all wiring and other electrical
components such as circuit breakers, disconnect
switches, etc. should be determined by the individual
job requirements and should not be based on the size
and/or type of connection provided on the equipment.
All installations should be made in compliance with all
governing codes and ordinances. Compliance with all
codes is the responsibility of the installing contractor.
