Section 1 – Model Overview & Specifications:
Model HCMF Series – High Capacity Meat Freezers
The HCMF is a compact, custom freezer designed for short-term grill-side storage of frozen
hamburger patties and secondary grilled product, providing quick and easy access at point-of-use.
Designed to be positioned immediately adjacent to the Grill Station, the HCMF is available in two
sizes, 18-inches wide and 30-inches wide, with a front case-loading door and an insulated, automatic
roll-back top lid that provides quick access, with minimum exposure of frozen product.
Unlike previous grill-side freezers (GSF & FRGSF), HCMF Models have a top mounted condenser
package that provides easy access for regular PM and service access from five sides. HCMF Models
are more energy efficient, provide more storage space, cost less to operate and have the following
specifications and utility requirements:
*NOTE: P/N: 18005519 has the condenser mounted top-right. P/N 18005056 has the
condenser factory-mounted top-left.

Check temperature controller circuit for defrost
heater. Does relay close when manual defrost is
initiated? If not, replace temperature controller.
(See Tips T-2)
Check high temperature cutoff switch for proper
function. If needed, replace.
Check the defrost heater integrity. If needed,
replace defrost heater. (See Tips T-9)
Refrigerant charge is
not correct or system

Inspect service valves, lines, joints and
components for signs of leaks, kinks or restrictions.
Check system pressure and check for leaks. If
leak is found, repair leak.
Condensing unit is not
starting properly or is
tripping on overload.
Ensure condenser coil is clean, unobstructed and
being cleaned every three months (or more
frequently, if needed) per HCMF PMM Page
instructions. If dirty or obstructed, vacuum or brush

Section 7 – Operator Preventive Maintenance:
NOTE: Before attempting service, failure diagnosis or component
repairs, verify basic operator maintenance has been done.
PROBLEM: Freezer is running but will not reach 0F [-18C] or
lower. High temperatures caused by a dirty condenser coil,
blocking the front or side louvered panels or direct contact with
the Grill Station may cause the freezer to function improperly, not
maintain temperature or cease operating.
1) FIRST- Perform a Manual Defrost: Push and HOLD (for
five seconds) the lower button to the left of temperature
display. Display will read: dEF.
2) Open the front compartment door and verify that freezer has
been defrosted. If significant ice buildup is still present, turn
OFF rear power switch, open the freezer compartment door
and allow the ice to melt.
3) Check to see if freezer is overloaded or if plastic carton
liners are obstructing evaporator fan openings.
4) Check freezer door gasket for damage. If damage is found,
replace the door gasket.
5) Check rear and side clearance around unit. To operate
efficiently, the following clearances are recommended:
Model
Min.
Side Clearance
Min.
Rear Clearance
HCMF-18 0” (2” recommended) 1” (2” recommended)
HCMF-30 0” (2” recommended) 1” (2” recommended)
6) Pull off front louvered access panel. Inspect the condenser
coil to ensure it is clean and free of dust and debris. If it is
dirty, clean it with a soft bristle brush or portable vacuum.
7) Test unit for operation within the 0to -10F [-18 to -23C]
normal operating temperature range.
8) If these steps correct problem, notify unit manager of
problems noted with crew cleaning, operator preventive
maintenance or location of unit. If problem persists, see
Troubleshooting Guide.
[Photo 1]
If freezer needs defrosting, push
and hold lower button for five
seconds. Display will read: dEF.
[Photo 2]
To inspect condenser coil, pull off
the front access panel. It has right
& left magnetic catches.
[Photo 3]
If condenser coil is dirty, clean with
soft brush or portable vacuum.

Condenser Package Replacement Tips:
P/N: 19004507 or 19004310
1. Rear, left side and right side access panels can be removed to
provide easy access to the condenser package.
2. Slit insulation on refrigeration lines 6” [15-18 cm] above enclosure
bottom. Push back or remove enough insulation to expose sweat
joints. Sweat those joints to separate compressor from evaporator.
3. IMPORTANT: Recover any residual refrigerant and ensure line
pressure is equalized to zero, before opening the refrigeration
system.
4. NOTE: When resealing the system, use a continuous Nitrogen
charge to assure no contaminants enter the system, especially
when brazing.
