For 3 Cabinet Units: 108”, 120”, 132” and 144” See Figure 6
NOTE: All installation should be done to meet local building codes.
1. Determine mounting location of center cabinet (See Figure 6).
2. Using template provided, determine mounting location for
Cabinet A (left side), left of center cabinet.
3. Drill holes and attach mounting hardware (not included) for
Cabinet A.
4. Mount Cabinet A on wall and securely tighten hardware.
5. Repeat steps 1, 2, 3 and 4 for mounting Cabinet B (center).
6. Repeat steps 1, 2, 3 and 4 for mounting Cabinet C (right),
right of center cabinet.
7. Secure Cabinet A to Cabinet B to Cabinet C using parts pro-
vided in installation kit. After alignment of cabinets is com-
pleted, carefully secure all assembly mounting hardware.
8. Install motor/blower assembly (A) in Cabinet A. Pass pres-
sure switch hose through proper hole on blower base.
Attach hose to right blower. Secure two wing nuts on blower
base. Reconnect motor (A) electric cord plug assembly.
9. Install motor/blower assembly (B) in Cabinet B. Pass pres-
sure switch hose through proper hole on blower base.
Attach hose to right blower. Secure two wing nuts on blower
base. Reconnect motor (B) electric cord plug assembly.
10. Install motor/blower assembly (C) in Cabinet C. Pass pres-
sure switch hose through proper hole on blower base.
Attach hose to right blower. Secure two wing nuts on blower
base. Reconnect motor (C) electric cord plug assembly.
11. Replace intake grilles with louvers facing down and fasten
knurled nuts.
12. Refer to “Field Power Wiring” and “Field Control Wiring”
sections, page 5 for single cabinet installation in this manual.
All instruction and safety warning and notes also apply to
electrical connections of multiple cabinets. Additional steps
are necessary only for harness connection of Cabinet A to
Cabinet B and Cabinet B to Cabinet C and/or to the Main
control Box.
13. Refer to wiring diagram on the inside of the hinged cover of
the Main control Box and to applicable wiring diagrams in
this manual. Harness wires are provided with the right ends
of the harness wires already connected to the unit and the
installer has to connect the left ends of the harness wires to
the correct terminal points as shown in the diagram. The
cabinet wiring compartment covers will have to be opened.
These covers are also hinged to the cabinets. Route and
locate wiring and wire strap the wires as shown in
Figure 9 and allow for the movement of the wires as the
hinged covers are opened and closed.
14. Replace all hinged covers.
15. Unit is ready for operation.
16. Restore power to the unit. Call for heat through the thermo-
stat or through the door switch if supplied. Unit should run.
Check for correct air flow.
17. Inspect unit for excessive vibration during operation. If
excessive vibration is noticeable, disconnect power supply.
Inspect mounting installation and refer to “Trouble Shooting
Chart” page 7 for probable cause.
OPERATION
1. After power has been connected to unit, unit is ready to
respond to its control devices such as the thermostat or door
switches.
2. Air direction at outlet can be controlled by adjustable vanes
at the nozzle which compensates for possible draft condi-
tions.
NOTE: Air direction settings shown in Figures 7 & 8.
NOTE: Cold air will try to escape near top of doorway. Air flow
can be controlled by direction of nozzle louvers.
NOTE: Each unit is supplied with an air flow probing switch which
is located in each cabinet compartment and this is supplied with a
hose located in the suction side of the blower. A blower turning in
the wrong direction may be prevented from turning the heat on by
this switch.
MAINTENANCE
NOTE: Ball bearings are permanently lubricated and require no
further lubrication.
Cleaning:
1. The air curtain cabinet(s) may be wiped off with a damp
cloth. Do not allow motor to get wet. Do not use solvents or
harsh detergents.
NOTE: Keep air intake louvers clear of dirt and dust accumula-
tion which could affect performance.
2. Check blower wheels for accumulated dirt twice a year and
clean. If disassembly is required, see “General Servicing”
section.
