NOTICES

There are three different types of notices that you should be familiar with, a NOTICE, CAUTION, and WARNING.
A NOTICE is a special note used to call attention to a particularly important point. CAUTION is used to point out a
procedure or operation which may cause equipment damage. The WARNING notice is the most important of the
three because it warns of an operation that may cause personal injury. Please familiarize yourself with your new
cooker before operating it and heed the notices throughout this manual. The WARNINGS are listed below and on
the following page for your review prior to operating the unit.

INSTALLATION INSTRUCTIONS

CAUTION:

This equipment is manufactured for the use on a
particular voltage and phase which is specified on the
rating plate located on the inside of the door.

When your fryers arrive, look them over carefully
noting any damage on the freight bill. If concealed
damage is found after you have accepted the equipment,
report it to the carrier immediately as all claims must be
filled within 15 days of the receipt of the shipment.
Also, be sure to keep all packing materials as these will
be necessary to make any claim.

Follow these installation instructions carefully. A proper
installation is important for the operation of the fryers.

All installations must conform to all local and state
codes and well as the United States National Electrical
Code (ANSI/N.F.P.A. No. 70-1987). In Canada,
installations must be made in accordance to Canadian
Electrical Code Part I, CSA-C22.1.

Clearances:

Minimum clearance of 6" (15cm) must be maintained from
combustible construction on each side and the rear of the
equipment. This equipment may be installed on combustible
floors.

Maintain a minimum of 24"(61cm) clearance in front of the
fryer to provide for proper operation, maintenance and
servicing.

Wiring diagram(s) are located in the back of the ser vice
manual and inside the fryers.

The control (interlock) voltage for this equipment must be
120 VAC (US & Canada). For other countries please check
the rating plate.

Regular cleaning of this equipment, as well as the hood, is
an important part of proper maintenance. Refer to
Maintenance Requirement Cards for proper procedure and

cleaned on a regular basis and must be kept clear of any
grease build up. See the appropriate Maintenance
Requirements Cards.

Ventilation;
A proper ventilation system is also an important part of

the installation. For information on the construction and

Leveling the fryers will help ensure proper operation. To
level the fryers loosen the two set screws on the caster stem.
Rotate the collar of the caster to raise or lower the height of
the unit. Tighten set screws to lock the adjustment. Casters
should be adjusted so that the fryers are level and at the
correct height under the hood system.

Clean the fry tanks using the Boil Out procedure on
Maintenance Card 14A.
A wiring diagram is located in the back of this manual and
inside the fryers.

NOTE: When adding solid shortening to an
empty fry tank, first remove the baskets and
support racks and fill the bottom of the tank with
shortening, continue to pack the remaining
shortening into the tank. Place the basket support
rack on top of the shortening before turning the
unit ON. For liquid shortening fill to the level
lines indicated on the side of the tank.

cycle and go to normal operation. The melt cycle
cannot be overridden.
Make sure that the shortening is at the proper level
