INTRODUCTION

This manual contains important instructions for installing, using, and servicing a flammable refrigerant glass door

freezer merchandiser case, GFP-HG. Failure to properly install, use, or service this product could cause damage to

cabinet, explosion, fire, injuries and even death. A parts list is included with this manual. Read all these documents

carefully before installing or servicing your equipment.

STORE CONDITIONS

The GFP-HG are designed to operate in the controlled environment of an air-conditioned store. The store

temperature should be at or below 75°F and a relative humidity of 55% or less. At higher temperature or humidity

conditions, the performance of these cases may be affected and the capacity diminished.

The GFP-HG should not be positioned where it is directly exposed to rays of sun or near a direct source of radiant

heat or airflow. This will adversely affect the case and will result in poor performance.

If this case is to be located against a wall, there should be at least 6” space between the wall and the back of the

case. This space will allow for the circulation of air behind the case, which will prevent condensation on the exterior

surfaces.

DANGER

Risk of fire or explosion. Flammable refrigerant used. Consult instruction

manual/repair manual/owner’s guide before attempting to install or service this

product. All safety precautions must be followed.

DANGER

Improper or faulty hook-up of electrical components on the refrigeration units can

result in severe injury or death.

NEVER use an extension cord to power these units. All electrical wiring hook-ups must be done in

accordance with all applicable local, regional or national standards.

NOTICE

Installation and service of the refrigeration and electrical components of the cabinet

must be performed by a refrigeration mechanic and/or a licensed electrician.

The portions of this manual covering refrigeration and electrical components contain technical instructions intended

only for persons qualified to perform refrigeration and electrical work.

This manual cannot cover every installation, use or service situation. If you need additional information, call or write

our customer service Department.

PRE-INSTALLATION INSTRUCTIONS

INSPECTION FOR SHIPPING DAMAGE

You are responsible for filing all freight claims with the delivering truck line. Inspect all cartons and crates for damage

as soon as they arrive. If damage is noted to shipping crates or cartons or if a shortage is found, note this on the bill

of lading (all copies) prior to signing.

If damage is discovered when the cabinet is uncrated, immediately call the delivering truck line and follow up the call

with a written report indicating concealed damage to your shipment. Ask for an immediate inspection of your

concealed damage item. Crating material must be retained to show the inspector from the truck line.

INSTALLATION INSTRUCTIONS

CAUTION

Risk of fire or explosion due to puncture of refrigerant tubing; follow handling

instructions carefully. Flammable refrigerant used.

GENERAL INSTRUCTIONS

1. Be sure the equipment is properly installed by competent service people.

2. Keep the equipment clean and sanitary so it will meet your local sanitation codes. Clean the cabinet with a mild

detergent and water, then rinse.

3. Rotate your stock so that older stock does not accumulate. This is especially important for ice scream. A "First-

In, First-Out" rotation practice will keep the products in good salable condition.

4. Do not place product in the case when it is soft or partially thawed. Also, product should not be put in the case

for at least 6 hours after it is started.

5. Stock cases as quickly as possible, exposing only small quantities to store temperatures for short periods of

time.

6. When replacing burned out light bars, be sure that the electrical power to the lighting circuit is turned off.

NOTICE TO STORE OWNERS / MANAGERS

Moisture or liquid around or under the cabinet is a potential slip/fall hazard for persons walking by or

working in the general area of the cabinet. Any cabinet malfunction or housekeeping problem that creates a

slip/fall hazard around or under the cabinet should be corrected immediately.

If moisture or liquid is observed around or under the cabinet, an immediate investigation should be made by qualified

personnel to determine the source of the moisture or liquid. The investigation should determine if the cabinet is

malfunctioning or if there is a drainpipe leaking.

MECHANICAL

CAUTION

Risk of fire or explosion due to puncture of refrigerant tubing; follow handling

instructions carefully. Flammable refrigerant used.

CAUTION

Installation and service of the refrigeration and electrical components of the cabinet

must be performed by a refrigeration mechanic and/or a licensed electrician.

Remove front grille and check refrigeration lines to see that they are free (not touching each other or compressor).

Refrigeration system processing tubes for a cabinet possessing flammable refrigerant is painted red. Spin condenser

fan blade to see that it is free. Insulate quick connects with pipe insulation to prevent condensation and/or ice

accumulating.

Remove cabinet from crate base and slide into location. Cabinet must be level from side to side and front to back for

correct draining of coil pan and for self-closing doors to operate correctly. Allow minimum of 4” between back of

cabinet and wall and between top of cabinet and ceiling for proper condensing unit air circulation.

To comply with Sanitation requirements the cabinet must be mounted on legs (6” high min.), casters, or the base

must be sealed to the floor with an N.S.F. listed silicone sealant. When sealing to the floor, leveling bolts can be uses

to assure the cabinet is level before applying silicone sealant.

ELECTRICAL

WARNING

Before servicing electrical components in the case or the doors or door frames make sure all

power to case is off. Always use a qualified technician.

Check voltage and amps drawn on (TABLE 2) to determine proper line and fuse or circuit breaker size. Check power

supply for low voltage.

For example: If voltage reads “230” with no load, and it drops below “207” when the compressor tries to start, it is an

indication of too small supply wiring or too long to run.

It is recommended that a separate circuit be run for each cabinet to prevent another appliance blowing the fuse or

breaker, causing loss of product.

IMPORTANT

Models (3 door cabinet) are pre-wired internally with a 208-230V NEMA L14-20P plug and should only

be plugged into a NEMA L14-20P recepticle. See wiring diagrams for more details. The cabinet should

be grounded.

LEG / CASTER INSTALLATION

1. Screw legs / casters tightly into the rail

base mounting holes.

2/20 Rev. A 57-02694

DOORS

The cabinets have Anthony glass doors

that are equipped with a patented TorqueMaster

hinge system. The doors are easily adjusted using

a flathead screwdriver (Fig.3).

* The tension needs to be checked and set when

first install.
