    (Reference Accessory Installation Supplement)
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.
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 secured and not
     touching each other on any metal surface.
C. Verify proper voltage prior to powering the product.
     (See product label for reference).
D. Check all field wired components “if supplied” are
     wired correctly.
E. Check that the inlet air supply and the discharge air
     supply are free of obstructions.
F. Check that all air filter(s) and/or air intake grille(s) are
     in place and installed properly, as originally shipped.
G. Verify voltage to the product once more and turn
      power on.
H. Regardless of whether the product is mounted on the
     inside or outside of the door opening, set the air
     directional vanes in the discharge nozzle slightly
     outward to approximately 10-15° towards the outside,
     or the wind load. (FIG. 5).

I. For products with control panels, turn the HOA
   (Hand-On-Auto) selector switch to “On” position and
   open the door to energize the product. For products
   without a control panel or an On/Off switch, open the
   door to energize the product.
FIG. 4
MAINTENANCE J. If heated products are installed, reference Heated
   Products Supplement.
K. For three phase units, verify direction of rotation of
     blower wheels (note direction arrows on the blower
     wheel housing). Correct if needed by changing polarity
     of three phase power.
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.
      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.
