*Available on pan heaters for “H” and “P” defrost options only.
** PSC motors are not allowed for DOE/NRCan regulated applications.
DOE/NRCan applications will require Dual Speed or Variable Speed EC fans.
*** N Stock Units are for non-glide or glide refrigerants
**** G Stock Units are for glide refrigerants only
Additional refrigerants are shown
in the TABLE classied as Glide
and Non- Glide for selection of dual
speed or variable speed motors to
meet DOE/NRCan regulations.

1 RECEIPT OF EQUIPMENT
1.1 INSPECTION
All equipment should be carefully checked for damage or shortages as soon as it is received. Each shipment should
be carefully checked against the bill of lading. If any damage or shortage is evident, a notation must be made on the
delivery receipt before it is signed, and a claim should then be led against the freight carrier.
1.2 LOSS OF GAS HOLDING CHARGE
Each unit cooler is leak tested, evacuated to remove moisture and then shipped with a gas holding charge. Absence
of this charge may indicate a leak has developed in transit. The system should not be charged with refrigerant until it
is veried that there is no leak, or the source of the leak is located.
2 LOCATION RECOMMENDATIONS
For all defrost types (Air, Electric and Hot gas defrost) unit coolers must have proper airow to maintain a uniform
room temperature and have a complete defrost.
These units are draw thru design thus drawing air thru the cooling coil and discharging it into the room via the unit
fans. For best performance it is desirable to arrange the air discharge toward the door of the cooler to minimize
the entrance of warm moist air when the door is open. The unit must be at least 12 inches from the wall to assure
proper air intake.
