Handling & Installation
Even though the Nailor fan coil unit is a sturdily constructed unit,
great care should be taken when handling it. Care should be taken
to protect the blower assembly, coil, piping, and drain stub outs
during handling. The piping and blower assemblies should not be
used as handles for lifting or moving the unit. Units may also have
delicate internal components that could be damaged by improper
handling. Care should be taken to prevent impact forces on the unit
that may cause internal damage.
The units covered in this manual are not suitable for outdoor
installation and should never be used for that purpose. The units
should never be stored or installed where they may be subjected to
a harsh environment such as rain, snow, or extreme temperatures.
Care should be taken to prevent any materials such as paint,
plaster, drywall dust, and other construction materials from being
deposited in the drain pan, heater, coils, or on the motor or blower
wheels. Failure to do so may have negative effects on unit operation
and may result in premature failure. To prevent contamination, the
units should have some form of temporary covering placed over
them during construction.
For model series 35FH & 37FH; suspend the unit from the building
structure in a horizontal plane. Be careful not to obstruct the bottom
access panels with support channels or straps. When requested,
unit is supplied with field mounted hanger brackets for use with
hanger rod up to 3/8" (9.5) diameter. Hanger brackets or straps
should be screwed to the top corner posts, unit casing sides, or
alternatively onto the inlet and outlet ends of the unit. Fan coil
units are too heavy to suspend with the ductwork they must be
independently supported. For the 35FH Size 30 & 40 it is advised
that these units are mounted by a trapeze suspension. The unit
must be mounted level. The drain pan has a built-in slope to ensure
proper drainage. Field-furnished and installed accessories such
as ductwork, mixing boxes, economizers, dampers, and valve
packages must be independently supported and must not rely on
the unit for support.
After unit is mounted, the service connections such as water, drain
and electrical can be made. At this time it should be confirmed that
the proper types of service have been provided to the unit. The
water connections should be checked for line size, temperature,
and location. Electrical service to the unit should be compared to
the unit nameplate to verify compatibility. The routing, and sizing
of all piping, the type and sizing of all wiring and other electrical
components such as circuit breakers, disconnects switches, etc.
should be determined by the individual job requirements and should
not be based on the size or type connections provided with the
equipment. All installations should be made in compliance with all
governing codes and ordinances. This compliance to all codes is
the responsibility of the installing contractor.
