FIGURE 1 - Air Stream

The mounting hardware (supplied by others) should be capable of supporting a minimum of three (3) times the weight of the unit.

See Table 1.

NOTE: The Air curtain is weatherproof, therefore no special covering is required for outdoor mounting.

IMPORTANT: A minimum of 4” is recommended above the top of the

Air curtain for the installation and removal of the cover housing.

A. When determining the mounting location for the unit(s), make sure that nothing interferes with the curtain of air developed when the discharge vanes are directed from 0° to 20° toward the door opening.

If the air stream strikes any obstruction (the top edge of the doorway, a door opening device, etc.), the effectiveness of the unit will be greatly reduced. See Figure 1.

B. For optimum performance, the bottom of the unit (discharge nozzle) should be no more than 1” above the top of the door opening with the unit mounted flush to the wall. If the unit must be mounted higher, it must be spaced out from the wall ³/₈” for every inch the unit is above the door opening. For optimum protection, any void between the Air curtain and the wall should be sealed along the full length of the unit.

See Figure 2.

C. Electric heated units shall:

1. Have a minimum clearance of at least 4” between the sides and top of the unit and any combustible material.

2. Have a minimum clearance of at least 6’ between the bottom of the unit and the floor.

3. Be installed indoors only.

air curtain for supply voltage and current requirements.

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). See FIGURE 6.

D. 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 Electrically Heated air curtain(s) provided

with the optional remote thermostat: mount and wire

the thermostat according to instructions and wiring

diagram.

VI. MECHANICAL CONNECTIONS

A. ELECTRICALLY HEATED MODELS

The heater circuit may be controlled by a remote thermostat, or manually through a remote mounted three position - fan only/off/ fan with heat switch. Overheating protection is provided by auto reset thermal cutouts built into the blower assembly (see wiring diagram). Proceed to Section VII - OPERATING INSTRUCTIONS.

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. Depending on the type of controls ordered one or more of the following may be applicable. 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 or

selector switch. Either switch may be line voltage or

low voltage (24V).

b. Deluxe Control Package – The unit is activated by a

door or selector 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 a door or selector

switch AND a thermostat to provide supplemental

heating. NOTE: Not available with 575V motors.

2. Unheated units will have the fans activated by a door or

selector 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 or selector

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).
