5. Determine the exact mounting locations to suspend
the unit above the ceiling so that the unit is centered
and parallel with the door opening. Use (4) threaded
rods to suspend the enclosure to the ceiling.
Note: When installed in the ceiling above the door, the
air curtain must be moved 3/8” away from the wall for
every 1" above the door height.
6. If applicable, extended wall mounting brackets are
available for attaching the unit to a wall.
7. If applicable, for tandem installation (units longer than
72”) of products mounted side by side, allow no more
than 6” between the two units. Note that (4) sets of
threaded rods are used to suspend each unit to the
ceiling or center mounting brackets are to be used for
joining and top mounting tandem units.
8. Mount the product such that the discharge is flush with
the ceiling.
9. All wires must be connected internal of the unit and
some knockouts are provided. However, it may be
necessary to create your own knockout, as required.
10. The unit must be wired per NEC and local codes.
FIG. 1
FIG. 2
Electrical Field Wiring
1. For electric models, reference the Heated Products
Supplement.
2. The unit and any optional accessories must be wired
with the proper voltage to the junction box per the
wiring diagram. (FIG. 3, unheated products only)
Page 3
3. All 3 phase motors are bi-directional, which means
they can rotate in either direction. Follow directional
arrows on the blower wheel housings for proper
rotation. If the motor is rotating incorrectly, switch two
of the 3 phase power or motor leads and the motor will
rotate the opposite direction. Make sure all motors are
turning in the same and proper direction. (FIG. 3)
FIG. 3
WARNING
The following items must all be completed by a qualified
installer and checked off when completed
A. Re-check that the product has been installed
properly and is level and secure.
B. Check all terminal screws are tight and field wiring is
connected in accordance to National Electrical Code
and wired per the enclosed wiring diagram. For
electric heated models, ensure that the coils are

L. VERY IMPORTANT Using a clamp meter, measure
the amperage to each motor and ensure that they do
not exceed the amperage listed on the product label.
M. If applicable, adjust the air intake grille(s) such that
the output air stream reaches the floor. For
temperature control and environmental separation
applications, the air stream should reach the floor
with sufficient strength to create an air seal around
the door opening without creating turbulent mixing of
the inside and outside air. If applicable, adjust the air
intake grille(s) such that the output air stream
reaches the floor. For flying insect control
applications, the air stream should reach the floor
with maximum strength. If after proper installation
and adjustment, the product appears to be producing
too little or too much air for the application, contact
the manufacturer.
MAINTENANCE
To reduce the risk of fire, electrical shock or injury to
persons, observe the following:
A. Maintenance is to be performed only by qualified
personnel who are familiar with local codes and
regulations and are experienced with this type of
product.
B. Before servicing or cleaning the product switch power
off at service panel and lock service panel to prevent
power from being switched “ON” accidentally.
Routine maintenance is required to keep this product
operating at its peak performance and efficiency. Over
time, the housing, air intake grille, air intake filter,
blower wheels and motor(s) will accumulate a build up
of dust, debris and other residue. It is imperative to
keep these components clean. Failure to do so will not
only lower operational efficiency and performance, but
also reduce the useful life of the product. The time
between cleanings depends on the application, location
and daily hours of use. On average, under normal use
conditions, the product should require a thorough
cleaning once every six (6) months.
To clean the product, perform the following:
1. Verify the product has been disconnected from the
power source.
2. Use a damp cloth and either a warm mild soapy water
solution or bio-degradable degreaser, to wipe down
the exterior components of the housing.
3. To access the interior of the product, remove the air
intake grille(s) and/or air intake filter(s). This is
accomplished by removing the screws on the face of
the air intake grille(s)/filter(s) and releasing the grille by
pulling on the spring hinge.
4. Thoroughly clean the air intake grille(s) and clean or
replace the intake filter(s).
WARNING
5. Thoroughly wipe down the motor, blower wheels and
blower wheel housings. Be careful not to spray the
motor with a water hose.
6. The motor(s) require no additional lubrication. They
are permanently lubricated and feature double sealed
