INSTALLATION INSTRUCTIONS
Apartment Fan Coil: FSA
664 01 5001 00
5
Refrigerant Lines
NOTE
: Do not remove seals from coil until tubing
connections are ready to be made. See instructions
packaged with outdoor unit for connecting refrigerant
tubes.
Move Fan Coil into place and install refrigerant tubing as
follows:
1. Route tubing to connection points.
2. Remove plugs from liquid and suction tubes.
3. Clean tubing and braze in place.
4. Pressurize system and leak test. Repeat
procedure until leak free.
ELECTRICAL CONNECTIONS
!
WARNING
ELECTRICAL SHOCK HAZARD
Failure to turn off the main (remote) disconnect
device before working on incoming (field) wiring
could result in personal injury or death.
Incoming (field) wires on the line side of the dis-
connect found in the fan coil unit remain live, even
when the pull--out is removed. Service and main-
tenance to incoming (field) wiring cannot be safely
performed until the main disconnect switch (re-
mote to the unit) is turned off.
NOTE:
Before proceeding with electrical connections,
make certain that voltage, frequency, and phase
correspond to that specified on rating plate. Also, check to
be sure that the service provided by utility is sufficient to
handle additional load imposed by this equipment. Refer
to unit wiring label for proper field high--voltage and
low--voltage wiring. Make all electrical connections in
accordance with NEC and any local codes or ordinances
that might apply. Fan Coil must have a separate branch
electrical circuit. The Cooling Control Kit and the heater
packages provide a disconnect switch located within sight
and readily accessible to the unit.
NOTE:
All control kits are shipped from factory wired for
230V transformer operation. When 208V transformer
operation is required, move the black primary lead from
the 230V terminal to the 208V terminal.
Refer to Figure 1 for location of the electrical inlets. Refer
to unit rating plate for minimum circuit ampacity (MCA)
and maximum fuse or circuit breaker (maximum
over--current protection -- MOCP).
1. Provide power supply for Fan Coil in accordance
with unit wiring diagram and rating plate.
2. Connect line--voltage leads to field lugs. Use
copper wire only.
3. Use UL listed conduit and conduit connector for
connecting line--voltage leads to unit and obtaining
proper
ground.
Grounding
can
also
be
accomplished by using the ground lug provided in
the control box.
4. Install rubber grommet packed with unit in hole for
low--voltage wires.
5. Connect low--voltage leads to thermostat and
outdoor unit. Refer to Figures 4 and 5 and the
outdoor unit wiring label.
Use No. 18 AWG color--coded, insulated (35
˚
C
minimum) wire to make low--voltage connections
between thermostat and Fan Coil. If thermostat is located
more than 100 feet from Fan Coil as measured along
low--voltage wire, use No. 16 AWG color--coded,
insulated (35
˚
C minimum) wire. All control kits from the
factory utilize a printed--circuit board (PCB) which has a
low voltage circuit protective fuse (5 amp), fan motor
speed tap selection terminal (SPT), and time delay relay
(TDR) jumper. To disable the TDR feature, sever the
jumper wire JW1.

WARNING
ELECTRICAL SHOCK HAZARD
Failure to establish uninterrupted or unbroken
ground could result in personal injury or death.
According to NEC, ANSI/NFPA 70, and local
codes, the cabinet must have an uninterrupted or
unbroken ground in order to minimize potential
for personal injury or death if an electrical fault
should occur. The ground may consist of electri-
cal wire or metal conduit when installed in accor-
dance with existing electrical codes. If conduit
connection uses reducing washers, a separate
ground wire must be used.
