FWE ASU-9 AIR SUPREMACY AIR SCREEN 

DELIVERY INSPECTIONS & ELECTRICAL REQUIREMENTS

PACKAGING:

Your Air Screen Refrigerator is shipped from the factory on a wooden pallet and packaged in a durable 
cardboard container. The carton is attached to the wooden skid with the use of large staples. These should
first be removed to avoid scratching the unit when lifting off the crate. Remove the wooden pallet and 
strapping material, and the unit should be rolled off the skid. Avoid laying the unit on its front, side or back 
for removal of the pallet.

NOTE: FWE does not recommend laying the unit down on its front, side or back. However, 
if you must, please be certain to allow the unit to remain in an upright position afterwards for 
48 hours before plugging the unit in or attempting to place the unit in to service, to assure 
that the compressor oils and refrigerant may settle.

FWE’S POLICY ON DAMAGED GOODS:

There are two types of damaged merchandise: VISIBLE DAMAGE AND CONCEALED DAMAGE.

A. CRATE HAS VISIBLE DAMAGE:
1. The product / crate being received is visibly damaged.
2. The receiver should 

refuse the damaged merchandise.

3. Receiver should 

sign the bill of lading indicating which merchandise 

is being "refused due to damage".

B. CONCEALED DAMAGE:
1. Merchandise is damaged and could not be externally detected.

Your receiving operation should inspect for this type of damage.

2.

Save all packing material

.

3. Contact FWE Customer Service 815-459-7500 and alert them to the situation.
4. Receiver must call the carrier to schedule an inspection of the damaged merchandise within

15 days

.

A. Check SERIAL PLATE to be sure the unit is installed on the proper NEMA plug 6-20P (on standard unit) 

electrical supply.

B. WARNING: This unit is provided with a three-pronged grounding plug. Be sure that the unit is plugged 

into a properly grounded outlet to avoid the possibility of electrical shock.

CORD & PLUG:

Your Air Screen Refrigerator is supplied with a cord & plug attached. It is shipped coiled at the bottom of 
the cabinet, secured by a nylon strip. For your safety and protection, all units supplied with a cord and plug
include a special three-prong grounding plug on the service cord. Select only a dedicated electrical outlet 
with grounding plug for power source. NOTE: Do not under any circumstances, cut or remove the round
grounding prong from the plug, or use an extension cord.

POWER SUPPLY:

The supply voltage should be checked prior to connection to be certain that proper voltage for the cabinet
wiring is available (refer to the serial tag to determine correct unit voltage). Make connections in accordance
with local electrical codes. Use qualified electricians. Use of a separate, dedicated 20 amp circuit is required.
Size wiring to handle indicated load and provide necessary overcurrent protector in circuit (see amperage
requirements on the unit’s serial tag).

WIRING DIAGRAM:

Refer to the wiring diagram for any service work performed on the unit. Should you require service, 
please contact FWE and provide the model and serial number of the unit involved.
