Propane is approved for use as a refrigerant in commercial, self-contained units in Canada
and USA under limited use conditions. It can be used in new equipment only, retrofitting is
not allowed, with a limited charge of up to 150 grams (5.3 oz) per refrigeration circuit. Even
though this is a small amount, it still presents a fire/explosion hazard if it leaks out of refrig-
erant containing parts. When mixed with air, a flammable propane-air mixture can be created
and easily ignited by sparks, open flames, or hot surfaces. This is particularly true in confined
zones. Propane is heavier than air and tends to settle at lower points.
To mitigate the risk, please follow the precautionary measures as follows:
• Avoid unit installation in areas with open flames (kitchens, repair garages or the like), or
in vicinity of open flames or high surface temperatures.
• Avoid unit installation in confined spaces. Well ventilated areas are preferred. Keep clear
all ventilation openings of obstructions.
• Do not rely on smell to detect potential leaks of propane refrigerant. Propane refrigerant is
a high purity propane gas and does not contain any stenching agent(s). Stenching agents
are typically used in fuel-grade propane and natural gas to detect their presence in air by
relying on smell.
• All repairs must be performed in well ventilated areas.
• To minimize the risk of possible ignition due to incorrect parts or improper service, compo-
nent parts shall be replaced with like components and servicing shall be done by service
personnel authorized by Minus Forty Technologies Corp.
• Do not attempt to modify the unit or remove any functional part(s) from the unit.
• Handle the unit with care to avoid any damage.
• When transporting the unit, all appropriate safety considerations must be considered.
Check with local Department of Transportation for detailed requirements pertaining to
transportation of flammable gasses.

CABINET LOCATION: An air space of at least 1” (2.5 cm) must be maintained on all sides of the freezer.
Do not locate the freezer in a warm unventilated room exceeding 86ºF (30ºC) and 55%RH; do not place
freezer in direct sunlight; do not place freezer under or near heat range or heating vent.
CABINET LEVELING: The freezer must be completely leveled side to side and front to back or slightly
tilted front to back but never tilted forward. Once the freezer is placed in its final location, use a car-
penter level to level the freezer. Proper leveling of the freezer is important for the door closing and
water drainage during the defrost cycle. There are two leg levelers in the front that can be adjusted. First,
loosen the nuts using an adjustable wrench. Second, turn levelers counter-clockwise to raise the freezer,
or clockwise to lower, until they reach the leveled position. Lastly, tighten the nuts again to lock the legs.
INSTALLATION INSTRUCTIONS
• DO NOT USE AN EXTENSION CORD
• DO NOT CUT, REMOVE OR BYPASS THE GROUNDING PRONG FROM THE PLUG
• DO NOT PLUG FREEZER INTO AN OUTLET CONTROLLED BY A WALL SWITCH
• ENSURE POWER CORD IS NOT CUT OR DAMAGED FROM PINCHING, KNOTTING, OR MISHANDLING
NOTICE:
Failure to follow these instructions may void the warranty and/or cause loss of product.
All models require a 15 Amp dedicated and properly grounded 115V/60Hz/1Ph circuit
with a NEMA 5-15P receptacle. Wiring should be sized according to the amperage
rating stated on the serial plate. Failure to use a dedicated circuit may cause the circuit
breaker to trip off and/or cause voltage drops. As a result, power to the freezer may be
interrupted and freezing performance can be adversely affected which may cause equip-
ment damage and/or product loss.
Voltage supply to the freezer must not vary more than ±10% of the nominal 115V, or performance may
be affected. The warranty and liability does not cover damage resulting from excessive voltage
variations.
The anti-fog glass door has a protective film on the inner side. After the
unit has been installed, peel and remove the protective film covering
the inner glass surface.
WARNING
These freezers MUST be installed on a dedicated grounded circuit protected with a 15 Amp circuit breaker
or a 15 Amp time delay fuse. Do not remove ground prong. If the cord or plug is damaged, replace with the
same type. Refrigeration and electrical work must be performed by a qualified technician. Failure to follow
these instructions can result in death, fire, or electrical shock.

This freezer is designed for automatic defrost. Every eight hours the refrigeration system is turned OFF and
the defrost/drain heaters are activated to melt the ice from the evaporator coil and drain pan. If the freezer
is not leveled properly, the water may not drain out of the freezer, it will re-freeze and ice gradually builds
up. Excessive ice buildup reduces cooling performance and may cause the failure of refrigeration system
and product loss. Ice buildup may be noticed through the evaporator fan grill on the coil fins.
To perform a manual defrost, follow these steps:
1. Press the UP arrow button and hold it for 6 seconds.
2. Wait until the electronic control stops defrost (the Def LED dot flashes)
3. If ice is still noticeable on the evaporator, press the freezer switch to the “Off” position then
disconnect the freezer from the power supply.
4. Take down the evaporator shroud and use a hair dryer to quickly melt the ice.
5. Make sure the freezer is leveled side to side, and front to back or slightly tilted front to back.
6. Replace the evaporator shroud.

NOTE:
The cleaning of the condenser is a service not covered under the warranty
The freezer is designed for minimal condenser cleaning. With the “lint free” condenser design, most
dust and dirt will pass right through the condenser. To insure the proper operation, we recommend
scheduled check-ups and cleaning every three to four months. This period may be shorter or longer
depending on the location in which the freezer was installed. A dirty condenser can result in a voided
warranty, part failure, product loss, and higher electrical cost. The steps to clean the condenser are as
follows:
CONDENSER CLEANING
1. Remove the front bottom grill (see page 9)
2. Switch off power at freezer switch on control panel.
3. Unplug power cord from electrical receptacle.
4. Brush the dirt, dust and paper off the condenser coil plate, all the way to the fan. Use either a
vacuum or blow with a compressed air supply if available.
5. When finished with cleaning, plug power cord back into receptacle.
6. Switch power back on at switch on control panel.
7. Replace bottom grill (see page 9)
CABINET CLEANING
To clean the exterior whether it has the original finish or a decal package, use only a mild non-abrasive
liquid cleaner, water and a soft cloth. For stainless steel parts, a commercial stainless steel polish and
cleaner can be used. Always apply the cleaner to the soft cloth and then clean the freezer. Never apply
the cleaner directly to the freezer. Excess liquid applied to the surface may seep into the electronic con-
trol and switches which can cause an electrical hazard or a malfunction.
DO NOT USE abrasive or caustic cleaners, scouring pads, solvents or flammable liquids.
CAUTION
Do not apply hot water on cold glass components. Allow glass to warm sufficiently to prevent
shattering.
CAUTION
Do not use ammonia or bleach based cleaners or abrasive type cleaners.
Do not use abrasive cleaning pads.
WARNING
To reduce the risk of fire, electrical shock or personal injury, disconnect the freezer from the power
source before cleaning. Press the freezer switch to the “Off” position, then unplug the power cord
from the receptacle. Keep liquids away from electrical and electronic components.
GENERAL
The freezer should be cleaned at regular intervals to meet a good standard of hygiene and
to keep the freezer attractive as an effective point of purchase display.
INTERIOR CLEANING
Use only mild non-abrasive liquid cleaner, water and a soft cloth for the entire freezer
interior. Make sure to wipe off all residue.
EXTERIOR CLEANING
Use only mild non-abrasive liquid cleaner, water and a soft cloth for the painted surfaces and
a stainless steel polish and cleaner for the stainless steel surfaces if desired.
CLEANING GLASS DOOR EXTERIOR
Due to the special coating on the glass, use only a mild, non-abrasive liquid cleaner, water,
and a soft cloth. The same applies to the plastic door frame.
ANTI FOG GLASS DOOR INTERIOR
The anti-fog glass door has a protective film on the inner side. After the unit has been
installed, peel and remove the protective film covering the inner glass surface.
The Anti-Fog coating is a scratch resistant, permanent coating applied on the inner surface
of the door glass. It prevents fogging and icing of cold glass surface after door opening and
closing.
Cleaning can be performed using common household glass cleaners (Sidolin®, Windex®,
Mr. Muscle ®) and a tissue or paper towel. However, on very cold surfaces these cleaners may
freeze. In these cases a mixture with 30% pure alcohol and water may be used.
At temperatures above 0°C, warm hand temperature water with a mild detergent can be
applied.
Do not use abrasive cleaners or materials like Ajax®, Scotch Brite® or Steel Wool.
Do not contaminate the door with silicone.
Do not use tape, glue, stickers, attachments, magic markers or similar products on the
coating.
Do not use razor blades or any other mechanical device to remove foreign residues or
objects directly from the coating.
