START-UP
This product has been assembled and tested at the
factory prior to shipping. The following procedures
should be performed to assure its performance. Before
continuing with the start-up, it is important to recognize
the safety controls furnished with the unit.
NOTE
For accessory installation, reference Accessory
Installation Supplement.
For heated products, reference Heated Products
Supplement.
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. 3).
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.
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.
WARNING
Prevent hazard of electrical shock. More than one
disconnect switch may be required to de-energize this
product.
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 secured and not touching each other on any
metal surface.
C. Verify proper voltage prior to powering the
product. (See product label for reference).
