Note: If a longer cable is required than was supplied,
it can be ordered from the factory or made by using
standard flat telephone cable, phone jack connectors
and the proper crimping tool.
G. Remote mounted Display Faceplate - if operation of the
Intelliswitch is desired through a remote mounted display
face plate continue, otherwise skip to step H.
NOTE: Maximum mounting distance between the Dis-
play Faceplate and the unit is 20' .
The unit MUST be factory ordered with the remote mount-
ed faceplate option.
1.
When the remote faceplate option is ordered from
the factory the air door comes equipped with the
blank faceplate and 12' ribbon attached. The Display
Faceplate is shipped loose ready for field installation.
2.
Locate the male end of the 14-conductor ribbon cable
in the wiring tray and run to the remote display loca
tion. The cable is minimum CL2 rated and should not
need to be in conduit.
3.
Connect the ribbon cable to the 14-pin socket with red
stripe positioned on the top left when facing the front
of the display board.
4.
Mount remote faceplate to the wall.
H. Reinstall the wiring tray cover.
I.
For Electric, Steam and Hot Water air doors proceed to
Section VI - Field Connections otherwise proceed to
Section VII - Operation and Controls.
VI. FIELD CONNECTIONS
A. ELECTRICALLY HEATED MODELS
The heater circuit may be controlled by a remote
thermostat or manually through the Intelliswitch located
on the discharge side of the air door. Overheating
protection is provided by auto reset thermal
cutouts built into the heater coil assembly
(see the wiring diagram).
B. STEAM OR HOT WATER HEATED MODELS
Piping should be done in accordance with local
codes, regulations and standard practices.
Connect the building system supply and return to
the ¾" MPT nipples on the heating coil. See Figure 8.
FIGURE 8 - Steam/Hot Water Connections
VII. OPERATING INSTRUCTIONS
A. GENERAL OPERATION
Air curtain operation may be divided into four areas:
control package, fan activation, fan speed selection,
and heat activation. The air curtain must be properly
installed before it is used.
1. Control packages control the unit's sequence of operation.
Unit modes/control packages are built into the unit and may
not be changed in the field.. Refer to your wiring diagram
for specifics about activation connections and sequence of
operation.
a. Basic Control Package – The unit is activated by a door
switch. The door switch may be line voltage or low
voltage (24V).
b. Deluxe Control Package – The unit is activated by a door
switch, but has a factory installed time delay allowing
the unit to keep running for a period of time after the
door closes.
c. Comfort Plus Control Package – Available only on heated
units, the unit is activated by the door switch OR by the
thermostat to provide supplemental heating.
2. Unheated units will have the fans activated by a door switch
or sensor. The unit may be single speed and require no fan
speed selector (On/Off ), or may have multiple fan speeds
which require either a unit or remote mounted switch
(Off, High, Med, Low).
3. Heated units will have fans activated by a door switch or
sensor, but may also be activated by the thermostat in
Comfort Plus Mode. The unit may be single speed and
controlled by either a unit or remote mounted switch (Fan,
Off, Heat), or may have multiple fan speeds which can be set
by either a unit or remote mounted switch (Low, Med, High,
Off, Low heat, Med Heat, High Heat).
4. Heat activation is controlled by either a unit or remote
mounted thermostat, and a unit or remote mounted switch.
B. AIR STREAM ADJUSTMENT
1. With the air curtain operating and the door in its full open
position, check to see that nothing is obstructing the airflow
at the discharge nozzle vanes.
2. Find the air stream split location. Hold a handkerchief by
its corners, approximately 12" above the floor. Gently move
the handkerchief back and forth in the doorway. Make sure
the air is being directed to both the inside and the outside.
See Figure 9. The split location is indicated where the
handkerchief is vertical with minimal or no fluttering.
3. The split location should be approximately 3" outside the
doorway. If necessary adjust the discharge nozzle vanes by
de-energizing the unit, loosening the nozzle vane locking
screws and adjusting vanes.
