General Sequence of Operation — Refrigerators & Freezers
USER ACTION!
For more information regarding an appliance's temperature control adjustment or general sequence of operation,
please see our Commercial Refrigeration General Control Guide in our resource library at
truemfg.com/support/manuals/#panel4 or scan the QR code.
When the appliance is plugged in…
1. The interior lights illuminate on glass door models (if not, see “Light Switch Location” (pg. 21).
2. The electronic temperature control display illuminates (if installed).
When the appliance is in refrigeration mode
1. There may be a short delay before the compressor and/or evaporator fan(s) start. This delay may be determined by time
or by temperature. This delay may also be the result of an initial defrost event that will be a minimum of six (6) min.
2. The temperature control/thermostat may cycle the compressor and evaporator fan(s) on and off together.
EXCEPTION: models TSID, TDBD, TCGG, and TMW do not have evaporator fan(s).
3.
The temperature control cycles the compressor by sensing either an evaporator coil temperature or air temperature, not a
product temperature.
a. Mechanical Temperature Control or Electronic Temperature Control with a Knob
i. The temperature control cycles the compressor on and off as determined by the cut-in and cut-out temperatures.
1. #9 is the coldest position
2. #1 is the warmest position
3. #0 or Off is the compressor off position
b. Electronic Temperature Control with a Display
i. The temperature control cycles the compressor on and off as determined by the set point and differential temperatures.
1. The set point is the adjustable preprogrammed temperature designed to be either the cut-out temperature or it will
match the average appliance holding temperature (only when used with a high and low differential).
2. The differential temperature(s) is the non-adjustable preprogrammed temperature used to determine when the
compressor turns on and off (only when the set point is the average holding temperature).
4. An analog thermometer, a digital thermometer, or an electronic control display may reflect the refrigeration cycle swings of up
and down temperatures, not a product temperature. The most accurate method to determine an appliance’s operation
is to verify the product temperature.
5. There may be times during refrigeration mode or defrost mode that the condenser fan motor will reverse to blow dirt off the
condenser coil.

General Sequence of Operation — Refrigerators & Freezers (cont.)
When the appliance is in defrost mode…
1. Every appliance requires a defrost event to ensure the evaporator coil remains clear of frost and ice buildup.
2. Defrost is initiated either by the temperature control or a defrost timer.
EXCEPTION: Models TDC, TFM, THDC, and TMW require a manual defrost. The frequency of this manual defrost depends on
the appliance’s usage and ambient conditions.
a. Mechanical Temperature Control
i. The temperature control cycles the compressor on and off as determined by the cut-in and cut-out temperatures.
1. During this time, only the evaporator fan runs.
EXCEPTION: Models TCGG, TDBD, and TSID do not have an evaporator fan(s).
ii. A freezer with a mechanical temperature control will defrost by time initiation as determined by a defrost timer
1. During this time, only the defrost coil heater and drain tube heater are energized.
2. Defrost terminates when a specific evaporator coil temperature is reached or by a time duration.
iii. Models with an analog or digital thermometer may show higher-than-normal temperatures during defrost.
b. Electronic Temperature Control
i. The temperature control is preprogrammed to initiate defrost by a time interval but may also be initiated by
temperature demand.
1. During defrost, a refrigerator turns off the compressor to use the evaporator fans to clear the evaporator coil.
2. During defrost, a freezer turns off the compressor and evaporator fan to use electric heater to clear the evaporator coil.
ii. The temperature with a digital display (if installed) shows dEF during defrost.
iii. Models with an analog or digital thermometer may show higher than normal temperatures during defrost.
iv. After defrost, there is a display delay until temperature is shown.
NOTICE ›
The display may have a short delay before showing a temperature after defrost has expired and may show
dEF during a refrigeration cycle.
When the appliance sounds an audible and visual alarm…
1. Please reference the appliance’s specific temperature control information in Commercial Refrigeration General Control Guide
for any alarm codes.

Stainless Steel Opponents
There are three basic things which can break down your stainless
steel’s passivity layer and allow corrosion to form.
• Scratches from wire brushes, scrapers, steel pads, and other
items that can be abrasive to stainless steel’s surface.
• Deposits left on your stainless steel can leave spots. You
may have hard or soft water depending on what part of the
country you live in. Hard water can leave spots. Hard water
that is heated can leave deposits if left to sit too long. These
deposits can cause the passive layer to break down and rust
your stainless steel. All deposits left from food prep or service
should be removed as soon as possible.
• Chlorides which are present in table salt, food and water, as
well as in household and industrial cleaners. These are the
worst type of chlorides to use on stainless steel.

8 Tips to Help Prevent Rust on Stainless Steel8 Tips to Help Prevent Rust on Stainless Steel
Maintain the Cleanliness of Your Equipment
Avoid build-up of hard stains by cleaning frequently. Use
cleaners at the recommended strength (alkaline chlorinated or
non-chloride).
Use the Correct Cleaning Tools
Use non-abrasive tools when cleaning your stainless steel products.
The stainless steel’s passive layer will not be harmed by soft cloths
and plastic scouring pads.
Clean Along Polishing Lines
Polishing lines ("grain") are visible on some stainless steels. Always
scrub parallel to polishing lines when visible. Use a plastic scouring
pad or soft cloth when you cannot see the grain.
Use Alkaline, Alkaline-Chlorinated or Non-Chloride Cleaners
While many traditional cleaners are loaded with chlorides, the
industry is providing an ever increasing choice of non-chloride
cleaners. If you are not sure of your cleaner’s chloride content,
contact your cleaner supplier. If they tell you that your present
cleaner contains chlorides, ask if they have an alternative.
Avoid cleaners containing quaternary salts, as they can attack
stainless steel, causing pitting and rusting.
Rinse
When using chlorinated cleaners, you must rinse and wipe dry
immediately. It is better to wipe standing cleaning agents and
water as soon as possible. Allow the stainless steel equipment to
air dry. Oxygen helps maintain the passivity film on stainless steel.
Never Use Hydrochloric Acid (Muriatic Acid) on Stainless Steel
Even diluted, hydrochloric acid can cause corrosion, pitting and
stress corrosion cracking of stainless steel.
Water Treatment
To reduce deposits, soften hard water when possible. Installation
of certain filters can remove corrosive and distasteful elements.
Salts in a properly maintained water softener can also be to your
advantage. Contact a treatment specialist if you are not sure of the
proper water treatment.
Regularly Restore & Passivate Stainless Steel
Stainless steel gets its stainless properties from the protective
chromium oxides on its surface. If these oxides are removed by
scouring, or by reaction with harmful chemicals, then the iron in
the steel is exposed and can begin to oxidize, or rust. Passivation is
a chemical process that removes free iron and other contaminants
from the surface of stainless steel, allowing the protective
chromium oxides to re-form.

Lid Maintenance
The lid pin screws are designed to be removed for cleaning.
Remember to periodically check the screws and ensure they are
tight. See lid pin screw locations below (figs. 1-4).
Composite Cutting Board Maintenance
Please see the message from Richlite® regarding composite cutting
boards material and preventing warping.
To prevent warping on cutting boards manufactured by
Richlite® material, simply turn the board over on a regularly
scheduled basis. Warping is caused by continued moisture and
temperature differences on the top and bottom of the boards.
By turning the board over, this will allow both sides of the
board to receive the same exposure.
There is a chance that larger sized boards may warp as a
characteristic of the material.
