ThIS CONTROL BOX IS FOR CONTROL PURPOSES ONLY
AND IS NOT TO BE USED AS A DISCONNECT. A SEPARATE
ELECTRICAL DISCONNECT IS TO BE SUPPLIED AS REQUIRED
BY NATIONAL ELECTRIC CODE.
1. Keyhole slots are provided for the mounting of the box.
Figure 1 shows the mounting pattern.

Mounting hardware may be preinstalled leaving clearance for
the box to engage the keyhole slot.
After mounting, tighten mounting hardware using access holes
provided in the inner base.
Fuses for the control transformer are optional but may be
required if the branch circuit is not fused. If fuses are required,
use:
208V 1/2A Fast Acting (Bussman KTK-1/2)
240V 0.4A Fast Acting (Bussman KTK-4/10)
480V 1/4A Fast Acting (Bussman KTK-1/4)
If the branch circuit is fused, the red and yellow cables on the
fuse block may be swapped with the red and yellow cables on
the control transformer. See Fig. 2.

not requiring fuses.
6.
Set up the control transformer for the appropriate voltage.
For 208V 1-phase operation make connections as shown
in Fig. 3. For 240V 1-phase operation make connections as
shown in Fig. 4. For 480V 3-phase operation make connections
as shown in Fig. 5.
Fig. 5 – Transformer Connections for 480V/3o.
7.
Connect the Air Door motor cables to terminals number 1 and 2
for 208V or 240V operation and to terminals 1, 2 and 3 for 480V
3-phase. Connect grounding conductor to terminal no. 4 (refer
to Fig. 6 – see also wiring diagram – next page).
installation
10. Make connection of the ground to the “GRD” terminal.
Fig. 6 – Air Door Blower Motor Terminal Block.
8.
For door switch operation (Ruskin Models: P-plunger switch or
R-roller switch) make switch connections to the switch terminal
block terminal No. 1 and 3.
Fig. 7 – Connect Door Switch “P-Plunger Switch” or
“R-Roller Switch” to terminals 1 and 3.
9.
Make supply connections to the terminal block shown in Fig.
8. If connection is being made to single-phase power 208V or
240V, then make these connections at “L1” and “L2”. If connecting to 480V 3-phase, make connections at “L1”, “L2” and
“L3” (see wiring diagram).
Fig. 8 – Supply Power Connections.
11. Test the Air Door operation. If a door switch is used, test (with
switch in “Auto” position) to make sure the Air Door starts when
the door is just starting to be opened. If the Air Door is 3-phase,
check for proper fan rotation. If the fan direction is incorrect,
switch any two of the power leads (Fig. 8.) L1, L2 or L3.

WARNING – TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND UNJURY TO PERSONS,
OBSERVE THE FOLLOWING:
1 Use this unit only in the manner intended by the manufacturer.
If you have questions contact the manufacturer.
2. Before servicing or cleaning unit, switch power off at service
panel and lock the service disconnecting means to prevent
power from being switched on accidentally. When the service
disconnecting means cannot be locked, securely fasten
a prominent warning device, such as a tag, to the service
panel.
3. Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable codes
and standards, including fire rated construction.
4. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.
5. Special attention must be given to any grounding information
pertaining to this product. To prevent the risk of electrocution,
the unit must be securely and adequately grounded. This
should be accomplished by connecting a grounded conductor
between the service panel and the grounding ring terminal
or green lead wire provided. To ensure a proper ground, a
qualified electrician must test the grounding means.
6. This product must NOT be used in potentially dangerous
locations such as flammable, explosive chemical laden, or
wet atmosphere.
WARNING: THIS FAN HAS AN INTERNAL SELF RESETTING THERMAL OVERLOAD PROTECTOR. ALWAYS
DISCONNECT FROM POWER SUPPLY BEFORE
SERVICING
WARNING: TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT USE THIS AIR CURTAIN
WITH ANY SOLID STATE SPEED CONTROL DEVICE.

Operation
There are three switch positions available on the Ruskin Control
Box. These are:
- Hand (Manual “Always On” )
- Off (Manual “Always Off”)
- Auto (Door Switch Operation)
maintenance
WARNING – ALWAYS DISCONNECT POWER SUPPLY BEFORE
SERVICING.
Cleaning:
The control box may be cleaned using a damp cloth. DO NOT USE
SOLVENTS OR HARSH DETERGENTS.
A typical air door installation will have varying needs:
1. When traffic through an entry is high it may be desirable to switch
to the “Hand”position so wear and tear on contactors and motors
can be minimized.
2. When the weather is mild and air conditioning, heat, and insect
control are not required, the air door can be turned “Off”.
3. When door traffic is lower and air conditioning, heat, and insect
control are desired, use “Auto” for door switch operation.
1. After disconnecting power supply, open the electrical box or
enclosure to gain access to the electrical connections.
2. If it is necessary to disconnect wiring during maintenance, label
wires as necessary to aid reassembly. Refer to Wiring Diagram.
General Servicing:
3. After servicing is complete, reinstall all component and electrical
connections.
