ICE CFA1012A I&O Manual 01/2021 New
2.7 Mounting the Unit
1. Using an appropriate and safe lifting device, set the CFA1012A on the bottom support bracket
mounted on the wall. You must stabilize the unit on the bracket with the lifting device or by some
other means - the bracket alone is not sufficient.
2. Make sure that the duct flanges are properly aligned with the wall opening. Adjust as necessary.
3. Apply silicone sealer to the perimeter of the unit, around the supply and return flanges, and over
the unused mounting holes.
4. Bolt the top and bottom of the unit to the shelter wall.
5. Apply a silicone bead to the top and perimeter where the unit meets the cabinet.
6. Pull the power and control wires through the conduit into the cabinet.
2.8 Electrical Connections
WARNING ELECTRICAL SHOCK HAZARD
Failure to follow safety warnings exactly could result in serious injury, death, and/or
property damage.
Turn off electrical power at fuse box or service panel BEFORE making any electrical
connections and ensure a proper ground connection is made before connecting line
voltage.
Important
All electrical work must meet the requirements of local codes and ordinances.
Work should be
done
only
by qualified persons.
The CFA1012A units are provided with labeled power leads and an eight-conductor thermostat cable.
High Voltage Wiring
The high voltage wire provided with the CFA1012A can be replaced to eliminate wire nut connec-
tions. L1, L2 and ground wires can be replaced at the circuit breaker.
The power supply(s) should have the proper voltage, phase, and ampacity for the selected models.
Low Voltage (Control) Wiring
1. Mount the sub-base on a level plane. Use a line and surface level. Connect the thermostat wire as
shown in Figure 4.
2. Attach the thermostat assembly to the sub-base. Check stage one anticipator settings - should read
.40.
Note:
Black and blue wires on the CFA1012A terminal block are dry contacts which can be used
for remote signaling in the event of equipment shut-off on low or high pressure limits.
3. Unit shut down is available from a field provided alarm device; i.e., smoke alarm, fire stat. Install
a normally closed device between red wire and the "R" terminal on the thermostat. This will
disable the 24V control voltage. See Figure 4.
NOTE:
THE INTERNAL TRANSFORMER IS NOT DESIGNED TO POWER OTHER EXTERNAL
DEVICES.
