FIGURE 4 - Installing Air Door on Wall Mounting Plate
V. ELECTRICAL CONNECTIONS
All electrical wiring and connections MUST be performed by
qualified personnel in accordance with the National Electri-
cal Code ANSI/NFPA No. 70 (latest edition) or, in Canada, the
Canadian Electrical Code, Part 1-C.S.A. Standard C22.1 and local
codes and regulations.
FIGURE 5 - Wall Mounting Plate Storage
A. Check the rating nameplate on the top of the air curtain for
supply voltage and current requirements. See Figure 7.
A separate line voltage supply with a suitable branch circuit
protection device should be run directly from the main
electrical panel to the air curtain. A disconnect switch for
each branch circuit is a required part of this installation.
B.
All field wiring must be copper with a minimum insulation
of 60° C within approved conduit. If any of the wire
supplied with the air curtain must be replaced, it must be
replaced with copper wiring with a minimum insulation of
90° C.
C. Remove the wiring tray cover; on air curtains that are
comprised of modules, remove the wiring tray cover that is
located closest to the electrical rating nameplate (if it has
not already been done).
D. Electric, steam and hot water heated air curtains are factory
equipped with a air curtain mounted solid state
temperature sensor cable (for the Intelliswitch thermostat)
located in the wiring tray. Depending where the tempera
ture is to be measured, the sensor may be left in the wiring
FIGURE 6 - Suspended Mounting
tray or it may be located outside of the air curtain. If the air
curtain is unheated, or the sensor will be left in the wiring
tray, skip to step E, otherwise continue.
1.
Remove the ½" bushing taped to the back of the
wiring tray cover and set aside.
2.
Determine mounting location of the temperature
sensor (do not mount at this time).
3.
Choose end of the wiring tray that the sensor will exit
the air curtain based on the mounting location from
Step 2.
4.
Locate the 1/8" hole on the wiring tray next to
the electrical knockout on the side determined in
Step 3.
5.
Drill out the 1/8" hole to ½".
CAUTION: DO NOT DAMAGE EXISTING WIRES IN
THE WIRING TRAY WHEN DRILLING.
6.
Maneuver the tip of the temperature sensor from
the inside of the wiring tray out through ½" hole.
7.
Thread the tip through ½" bushing from Step 1 and
snap the bushing into the wiring tray.
8.
Mount the temperature sensor. Do not put any clamps
on the rubber coated tip.
E.
The top of the air curtain has two knockouts on each side
of the air curtain, allowing for a left hand or right hand
power connection. Remove the required knockout if it has
not already been done and connect the power supply to
the air curtain. Connect all supply and control circuit wires
according to the wiring diagram provided.
NOTE: For Electric heated air curtains provided with the
optional remote thermostat, mount and wire the
thermostat according to instructions and wiring
diagram.
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.
