Maintenance

! Warning

General Maintenance

Disconnect power to the unit before performing
any service or maintenance functions.

DOOR GASKET MAINTENANCE

Door gaskets require regular cleaning to prevent mold
and mildew buildup and also to retain the elasticity of
the gasket. Gasket cleaning can be done with the use
of warm soapy water. Avoid full strength cleaning
products on gaskets as this can cause them to
become brittle and crack. Never use sharp tools or
knives to scrape or clean the gasket. Gaskets can be
easily replaced and do not require the use of tools or
an authorized service person. The gaskets are “Dart”
style and can be pulled out of the groove in the door
and new gaskets can be “pressed” back into place.

DRAIN MAINTENANCE - BASE

Each unit has a drain located inside the unit that
removes the condensation from the evaporator coil
and routes it to an external condensate evaporator
pan. Each drain can become loose or disconnected
during normal use. If you notice water accumulation on
the inside of the unit, be sure the drain tube is
connected to the evaporator drain pan. If water is
collecting underneath the unit, make sure the end of
the drain tube is in the condensate evaporator in the
machine compartment. The leveling of the unit is
important as the units are designed to drain properly
when level. Be sure all drain lines are free of
obstructions.

Part Number STH034 3/12 45

CASTER MAINTENANCE

Important

Wipe casters with a damp cloth monthly to prevent
corrosion.

NOTE: The power switch must be turned to OFF and
the unit disconnected from the power source
whenever performing service, maintenance functions
or cleaning the refrigerated area.

REFRIGERATORS

The interior and exterior can be cleaned using soap
and warm water. If this isn’t sufficient, try ammonia and
water or a nonabrasive liquid cleaner. When cleaning
the exterior, always rub with the “grain” of the stainless
steel to avoid marring the finish. Do not use an
abrasive cleaner because it will scratch the stainless
steel and can damage the breaker strips and gaskets.

STAINLESS STEEL CARE AND CLEANING

To prevent discoloration or rust on stainless steel,
several important steps need to be taken. First, we
need to understand the properties of stainless steel.
Stainless steel contains 70-80% iron, which will rust. It
also contains 12-30% chromium, which forms an
invisible passive film over the steel’s surface, which
acts as a shield against corrosion. As long as the
protective layer is intact, the metal is still stainless. If
the film is broken or contaminated, outside elements
can begin to break down the steel and begin to form
discoloration or rust. Proper cleaning of stainless steel
requires soft cloths or plastic scouring pads.

Never Use Steel Pads, Wire Brushes or
Scrapers!

46 Part Number STH034 3/12

Cleaning solutions need to be alkaline based or non-

!

Caution

chloride cleaners. Any cleaner containing chlorides will
damage the protective film of the stainless steel.
Chlorides are also commonly found in hard water,
salts, and household and industrial cleaners. If
cleaners containing chlorides are used, be sure to
rinse repeatedly and dry thoroughly. Routine cleaning
of stainless steel can be done with soap and water.
Extreme stains or grease should be cleaned with a
non-abrasive cleaner and plastic scrub pad. Always
rub with the grain of the steel. There are stainless steel
cleaners available which can restore and preserve the
finish of the steel’s protective layer. Early signs of
stainless steel breakdown are small pits and cracks. If
this has begun, clean thoroughly and start to apply
stainless steel cleaners in attempt to restore the
passivity of the steel.

Never use an acid based cleaning solution! Many
food products have an acidic content, which can
deteriorate the finish. Be sure to clean the
stainless steel surfaces of ALL food products.
Common items include: tomatoes, peppers and
other vegetables.

Part Number STH034 3/12 47

CLEANING THE CONDENSER COIL

!

Caution

In order to maintain proper refrigeration performance,
the condenser fins must be cleaned of dust, dirt and
grease regularly. It is recommended that this be done
at least every three months. If conditions are such that
the condenser is totally blocked in three months, the
frequency of cleaning should be increased. Clean the
condenser with a vacuum cleaner or stiff brush. If
extremely dirty, a commercially available condenser
cleaner may be required.

Failure to maintain a clean condenser coil can initially
cause high temperatures and excessive run times.
Continuous operation with a dirty or clogged
condenser coil can result in compressor failure.
Neglecting the condenser coil cleaning procedures will
void any warranties associated with the compressor
and cost to replace the compressor.

Never use a high-pressure water wash for this
cleaning procedure as water can damage the
electrical components located near or at the
condenser coil.

48 Part Number STH034 3/12

DOORS/HINGES

Over time and with heavy use doors and hinges may
become loose. If this happens tighten the screws that
mount the hinge brackets to the frame of the unit.
Loose or sagging doors can cause the hinges to pull
out of the frame, which may damage both the doors
and the hinges. In some cases this may require
trained & qualified service agents or maintenance
personnel to perform repairs.

NOTE: Do not place hot pans on/against the blue ABS
liner. Do not throw items into the storage area. Failure
to follow these recommendations could result in
damage to the interior of the cabinet or to the blower
coil. Overloading the storage area, restricting the
airflow, and continuous opening and closing of the
doors and drawers will hamper the unit’s ability to
maintain operational temperature.

PREVENTING BLOWER COIL CORROSION

Immediately wipe up all spills.

ANNUAL PLANNED MAINTENANCE

The following parts are recommended for annual
planned maintenance replacement to ensure optimum
unit performance and minimize downtime:

• Refrigerator door gasket (cleaning may be
sufficient)

Ice Making Sequence of Operation

VERSION 1 ICE MACHINE R404A REFRIGERANT

INITIAL START-UP

1. Placing the power switch in the “ON” position and
the flush switch in the “ICE” position, will supply
water to the reservoir.

2. The reservoir fills with water, the low water switch
closes and the gear motor starts.

FREEZE CYCLE

3. After the gear motor runs for 60 seconds the
compressor will start. The gear motor,
compressor, condenser fan motor and low water
switch remain energized as the ice machine
makes ice. The water float valve will open and
close automatically to maintain the proper water
level.

AUTOMATIC SHUT-OFF

4. The infrared bin control senses ice for 6
continuous seconds and starts a 90 second delay
period, After the 90 second delay period, the
compressor stops. 90 seconds after the
compressor stops the gear motor will stop.

RESTART AFTER AUTOMATIC SHUT-OFF

The gear and fan motor energize for 60 seconds to
clear the evaporator of any remaining ice and to
provide short cycle protection. 60 seconds later the
compressor energizes, starting a freeze cycle.

DRAIN CYCLE IN THE “ON” POSITION

After the ice machine has run for 12 hours the ice
machine will stop making ice and start a drain cycle.
The drain cycle will remove minerals that have settled
in the bottom of the evaporator. The drain cycle lasts
approximately 20 minutes, after which the ice machine
control board automatically resumes ice making and
resets the 12 hour counter to zero.

90 Part Number STH034 3/12

DRAIN CYCLE MANUAL OPERATION

Move ICE/DRAIN switch to DRAIN
If the ice machine is running:
90 seconds after the flush switch is moved to the

“Drain” position, the flush valve opens. and flushes the
reservoir and evaporator. The drain cycle continues
until the switch is moved to the “Ice” position.

If the ice machine is not running:
The drain valve opens immediately. The drain cycle

continues until the switch is moved to the “Ice”
position.

Part Number STH034 3/12 91

VERSION 2 ICE MACHINES R404A OR R290 REFRIGERANT

NOTE: Ice machines use an auger to remove ice from
the evaporator. Occasional noises (creaks, groans,
squeaks, or pops) are a normal part of the ice making
process.

Operation

The ice machine will not start until:

A. The compressor rocker switch is moved to

“ON”.

B. Ice does not contact the bin thermostat bulb.

C. The water reservoir is full of water.

With power supplied and the compressor rocker
switch in the ON position, the gear motor and
refrigeration system start. The float valve controls the
water inlet valve and water level. The freeze cycle
ends when ice contacts the bin thermostat. A
20 minute delay period initiates. The ice machine will
restart when ice no longer contacts the bin thermostat
and the 20 minute delay period expires.

Refrigerated Cabinet Operation

Default temperature setpoint = 36° F with a ±2° F
Differential

NORMAL OPERATION

The microprocessor control board controls the cabinet
temperature based on the input received from the
cabinet temperature thermistor. The thermistor value
is compared to the control board setpoint. When the
reach-in temperature is equal or greater than the
setpoint (plus half the differential) the compressor
relay closes provided the following conditions are
satisfied:

• Power has been uninterrupted to the control board
for a 3 minute period.

OR

• The 3 minute compressor time delay has expired.
The delay period starts after the compressor has
run and then cycles off.

The compressor relay opens when the reach-in
temperature is less than the setpoint (minus half the
differential).

EVAPORATOR AND CONDENSER FAN MOTOR OPERATION

The condenser fan motor and compressor share the
same relay. The evaporator fan motor relay is
energized continuously and the evaporator fan cycles
off only during cleaning cycle.

94 Part Number STH034 3/12

OPERATION IN THE CLEAN/SANITIZE CYCLE

During the weekly cleaning/sanitize cycle, the
evaporator fan motor relay and the condenser fan
motor/compressor relay are de-energized. The relays
cannot energize until the clean/sanitize cycle is
complete. Upon completion of the clean/sanitize cycle,
the relays will energize, provided the conditions listed
in normal operation are satisfied.

ADAPTIVE DEFROST

After 3 hours of cumulative compressor run time, the
compressor will be de-energized for fifteen (15)
minutes.

HIGH TEMP ALARM

High temp alarm will display when product thermistor
is above 42ºF for 30 minutes and the following
conditions are satisfied:

• 3 hours since power is applied

• 1 hour since cleaning cycle
Error display will reset when the temperature reaches

41ºF or below.

THERMISTOR FAILURE

If the microprocessor control board receives an open
or shorted cabinet thermistor signal, the following will
happen:

1. A fault is displayed on the LCD screen

- Cabinet sensor open

Or

- Cabinet sensor shorted

2. The microprocessor will initiate a default
sequence for the refrigeration system - 12
minutes on, 3 minutes off.
