Hydrocarbon Guidelines1
1. Hydrocarbon Guidelines
This section applies to R290 Hydrocarbon units only. To identify the refrigerant type, see the data plate
in the cabinet interior.
DANGER - Risk of fire or explosion. Flammable refrigerant used. Do not use mechanical devices or other
means to accelerate the defrosting process. Do not puncture refrigerant tubing.
DANGER - Risk of fire or explosion. Flammable refrigerant used. To be repaired only by trained service
personnel. Do not puncture refrigerant tubing.
CAUTION - Risk of fire or explosion. Flammable refrigerant used. Consult Service Manual or Owner’s
Manual before attempting to install or service this product. All safety precautions must be followed.
CAUTION - Risk of fire or explosion. Dispose of properly in accordance with federal or local regulations.
Flammable refrigerant used.
CAUTION - Risk of fire or explosion due to puncture of refrigerant tubing; follow handling instructions
carefully. Flammable refrigerant used.
WARNING - THIS UNIT USES R290, A HYDROCARBON, PROPANE REFRIGERANT THAT IS ENVIRON-
MENTALLY FRIENDLY BUT IS ALSO HIGHLY FLAMMABLE AND EXPLOSIVE. PLEASE READ THIS MANUAL
CAREFULLY AND FOLLOW ALL SAFETY PRECAUTIONS CONTAINED HEREIN TO AVOID THE RISK OF
FIRE OR EXPLOSION. FAILURE TO FOLLOW THE SAFETY PRECAUTIONS MAY RESULT IN SERIOUS
INJURY OR DEATH, AND/OR PROPERTY DAMAGE.

Hydrocarbon Guidelines 2
Propane (R290) is highly approved for use as a refrigerant in commercial, self-contained units in the US under
limited use conditions. It can only be used in new equipment. Backfitting or modifications of old equipment are
not allowed. It must be charged in a strictly limited volume of up to 150 grams (5.3 oz) per refrigeration circuit.
Even though this is a small amount, it still presents a fire or explosion hazard if it leaks out of parts that hold
refrigerant. When it comes in contact with air, a flammable propane-air mixture can be created and easily ignited
by electrical sparks, open flames or hot surfaces. The risk is higher in small, confined, poorly ventilated spaces.
Propane will settle at lower zones because it is heavier than air. To reduce these risks, observe the following
precautions
• Avoid installation of unit in areas with open flames or in general vicinity of open flames or high surface
temperatures.
• Avoid unit installation in small, confined spaces. Ensure ample ventilation at all times. Keep all exhaust vents
free of any blockage or obstruction.
• Do not rely on smell to detect potential leaks of propane refrigerant. Propane refrigerant is a high purity
propane gas and does not contain odourants or stenching agents. These additives are typically used in fuel-
grade propane and natural gas in order to give them a distinctive smell which makes it easier to detect leaks.
• General service and repairs must be performed in well-ventilated areas.
• General service and repairs must be performed only by professionals authorized by Everest Refrigeration.
• Component shall be replaced with Everest-issued, like components to minimize the risk of possible ignition
resulting from incompatible parts or improper repairs.
• Do not modify, re-appropriate or remove any functional part(s) from the unit.
• Handle the unit with care to avoid any damage.
• Practice safety guidelines when transporting the unit. Consult with your local Department of Transportation for
requirements in moving flammable gasses.

2. Installation Instructions
This section applies to all Everest products. Correct installation ensures proper performance and
longevity of your appliance. Professional installation by a trained refrigeration technician and
electrician is recommended. Warranty is void if the following guidelines are not met.
1. Inspect for any freight damage upon delivery
of the unit. If damage is detected, immediately
report it to an Everest representative. Everest is
not responsible for damage that occurs during
shipment.
2. Keep the unit upright at all times. The
compressor contains oil, refrigerant, lubricants,
and various chemicals. When tilted, these fluids
may shift and travel to sections where they
don’t naturally occur. This will lead to system
contamination and compressor failure.
3. Some units require caster installation for
proper performance. Visit our website at
www.everestREF.com and enter your product’s
model number in the search field to determine its
caster requirements.
4. Screw in the stainless steel corner guards that
come standard with chefbases. The corner guards
prevent cooking equipment from accidentally
sliding off the top surface.
5. Screw in the stainless steel top surface grips.
This should be used to safely maneuver the unit
for cleaning or relocation purposes.
6. Do not place your hands under the top surface
lip or on the unit chassis when moving it to avoid
injury from sharp edges, protruding parts or
weight impact.
7. Select a location with good air ventilation. Poor
ventilation rapidly increases ambient temperature.
High ambient temperatures exceeding 86°F
(30°C) promote excessive compressor activity in
order to maintain the desired cabinet temperature.
This will result in decreased performance,
advanced component failure and the risk of fire.
8. Position the unit so it’s front and right vents
are away from heat-generating equipment such as
stoves, ovens, etc. Heat sources rapidly increase
the temperature of the immediate vicinity. High
temperatures exceeding 86°F (30°C) promote
excessive compressor activity in order to maintain
the desired cabinet temperature. This will result
in decreased performance, advanced component
failure and the risk of fire.
9. A distance of 6” is required for back side
and left side clearance. This ensures proper
ventilation and prevents overheating which can
lead to advanced component failure and the risk
of fire.
10. Select a location with a hard, leveled surface.
Use a leveling tool on the unit to ensure proper
alignment. Proper door function and condensate
removal is dependent on accurate ba lance.
Install the front leg stabilizers for units that come
standard with it to ensure proper door / drawer
functions and unit stability.
11. Select a location close to an electrical wall
outlet to ensure direct connection without the use
of extension cords.

Installation Instructions 4
12. Select a location away from severe moisture conditions. This may compromise the unit’s electrical
components and lead to electrical shocks or the risk of fire.
13. Select a location that will not expose the unit to extremely dusty conditions. Environments with
high dust and debris content will significantly hasten condenser blockage and will result in decreased
performance, advanced component failure and the risk of fire.
14. Do not build an enclosure or cabinet around the unit. This will restrict air ventilation resulting in
elevated compressor activity, decreased performance, advanced component failure and the risk of fire.
15. The unit is not intended for use in food trucks. Limited space, lack of ventilation and ambient
temperatures exceeding 86°F (30°C) typical to this setting will result in elevated compressor activity,
decreased performance, advanced component failure and the risk of fire.
16. The unit is intended for indoor use only. Outdoor use will cause a decrease in performance,
advanced component failure and the risk of fire.
17. When mounting cooking equipment on the unit, ensure that the heat source is at least 6” from
the unit’s stainless steel top surface. As long as the distance requirement is observed, no other heat
protective measures are required. The top surface features dual air chambers and vents, as well as a
special layer of insulation that mitigate and disperse heat.

3. General Safety
This section applies to all Everest products. Use your appliance according to its designed function as
specified in this Owner’s Manual. Warranty is void if the following guidelines are not met.

Electrical Safety
7
Everest units come as 115 volts, 60 hertz, single
phase.
Everest units in this family are equipped with a NEMA
5-15P. A 15 amp breaker must be used for units that
come with a NEMA 5-15P plug.
The ground prong must not be removed to reduce
the risk of electric shock and related hazards. If the
grounding pin is missing, the cord must be removed
from use. If the outlet is a standard 2-prong outlet, it
must be replaced with the properly grounded 3-prong
wall outlet. Only a qualified electrician may install the
correct power source.
To guarantee electrical safety, the wall outlet and
circuit must be checked by a qualified electrician to
make sure it is properly grounded.
Remove debris from the power plug prongs using a
soft cloth or brush before connecting it to an outlet.
Assign the unit to a dedicated, undamaged electrical
circuit with a voltage rating that matches the data
plate. Check the incoming voltage with a multi-meter.
This avoids the overloading and overheating of circuit
wires which may lead to a fire.
Do not use extension cords, adapter plugs or
other third party electrical connections. Everest is
not responsible for issues resulting from improper
electrical connections, electrical power failures and
voltage fluctuations.
Everest does not recommend the use of generators in
conjunction with the unit due to voltage fluctuations
that may compromise electrical components.
Turn off the unit using the power button before
unplugging. Wait at least 5 minutes before re-
plugging to prevent damage to the compressor.
Do not unplug the unit by tugging on the power cord.
Grip the plug and pull it securely out of the outlet.
Prevent damage to the power cord by providing
sufficient clearance around and under the unit.
Do not use a power cord that shows cracks or
exposed wires. Power cords that have been severely
worn or damaged must be replaced with original
manufacturer parts and only by an authorized
technician.
4. Electrical Safety
This section applies to all Everest products. Basic safety precautions must be observed when using
electrical appliances in addition to the following. Warranty is void if these guidelines are not met.

Operation 8
Starting your Everest Product
After plugging in the unit, the current temperature
and compressor symbol will appear on the digital
temperature control’s LED display. will flash
at short intervals for 1 minute after which the
compressor(s) and condenser fan motor(s) will
initiate. At the beginning of every compressor cycle,
the condenser fan motor is automated to rotate in
reverse for 30 seconds in order to blow dust off the
condenser coil.
The evaporator fan motor(s) will initiate once the
evaporator coil reaches a specific temperature
relative to the digital temperature control setting
and for as long as the door is closed. A fan
symbol will appear on the LED display to
indicate that the evaporator fan is running.
Allow the unit to operate for 24 to 72 hours before
storing contents in the cabinet. This lets the cabinet
temperature fully stabilize. Use this time to verify
proper installation and operation.
The default temperature setting is 35.0°F (2.0°C) for
refrigerators and -4.0°F (-20.0°C) for freezers. The
factory recommended temperature range is between
33.0°F (1.0°C) to 40.0°F (4.0°C) for refrigerators and
-5.0°F (-21.0°C) to 0°F (-18.0°C) for freezers. Setting
the temperature outside of the recommended range
will cause performance issues and in some cases
may result in component failure that is outside of
warranty coverage.
The compressor, condenser and evaporator fan
motors run while the unit is on refrigeration cycle.
The compressor, condenser and evaporator fan
motors stop running while the unit is on defrost cycle.
The unit is preset to defrost every 5-6 hours with
a duration of 45 minutes or less depending on the
evaporator coil temperature. Changing the preset
outside of the default range will result in cooling issues
and advanced component failure.
The digital temperature control is intended to read and
display the cabinet’s air temperature, not actual food
product temperature. The displayed temperature may
fluctuate due to frequent or prolonged door operation.
The most conclusive method to determine a unit’s
cooling performance is to measure the food product’s
temperature using a digital food thermometer.
5. Operation
Use your Everest product according to its intended functions. Warranty is void if the following
guidelines are not met.

be obstructing circulation of refrigerated air. This
creates uneven temperature in the cabinet with
pockets of very cold air that may cause items to
frost or freeze over. Food items must not touch
the wall or floors of the cabinet and stay within the
boundaries of the food pan to prevent blockage of
air flow.
Condensation in the interior cabinet.
The drawer or gaskets may not be sealing properly.
If the gasket is loose, reattach. Check product
placement in the cabinet as it may prevent the
drawer from fully closing. Make sure the front legs
are installed and slightly tilted towards the front of
the unit.
Hot food items may have been stored in the cabinet.
The interaction between hot and cold temperatures
will promote condensation.
Mild condensation in warmer ambient temperature
conditions may occur due to frequent or prolonged
drawer operation.

Troubleshooting Guide 17
Condensation on the unit’s exterior
surfaces.
Highly humid environments will contribute to the
condensation build up on exterior panels. Providing
ample ventilation and air movement to a space will
reduce the humidity level.
The drawer or gaskets may not be sealing properly.
If the gasket is loose, reattach. Check product
placement in the cabinet as it may prevent the
drawer from fully closing. Make sure the front legs
are installed and slightly tilted towards the front of
the unit.
Noise level during unit operation.
It is normal for commercial grade compressors
and components to have a higher decibel output
compared to residential counterparts.
The unit may not be balanced evenly. Poorly leveled
units may cause components or fittings to misalign
or disengage during operation. This may produce
noise as a direct result of repeated surface friction
or impact.
The unit may not be securely mounted to the
floor. This may produce noise as a direct result of
repeated surface friction or impact.
Some sounds are normal for the refrigeration
process. A dripping sound, for example, is the result
of refrigerant circulation during the compressor rest
period.
