Hydrocarbon Guidelines
1
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. Flammable refrigerant used. Dispose of properly in accordance with
federal or local regulations.
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
ENVIRONMENTALLY 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.

Installation Instructions

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 isdetected, 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 inthe search field to determine its caster
requirements.
5 . Do not place yourhands under the unit when
moving it to avoid injury from sharp edges,
protruding parts or weight impact.
6 . Select a location withgood 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.
7 . Select a location 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 . Select a locationwith a hard, leveled surface.
Use aleveling tool on the unit to ensure proper
alignment. Proper lid function and condensate
removal is dependent onaccurate balance.
10 . Select a location close to an electrical wall
outlet to ensure direct connection without the use
of extension cords.
11. Select a location away from severe moisture
conditions. Thismay compromise the unit’s
electrical components andlead to electrical
shocks or the risk of fire.
12 . Select a locationthat will not expose the unit
to extremely dusty conditions. Environments with
highdust and debris content will significantly
hasten condenser coil and condenser coil air
filter blockage andwill result in decreased
performance, advanced component failure and
the risk of fire.
13 . 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.
14. The unit is not intended for use in foodtrucks.
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.
15 . Theunit isintended for indoor use only.
Outdoor use will cause a decrease in performance,
advanced component failure, and the risk of fire.
4. If the unit is not equipped with casters or legs, it
must be sealed directly to the floor to prevent the
accumulation of dirt and debris. Apply sealant on the
expansion gap between the unit's edge and floor and
allow for 24 hours to air-dry before use.
8 . A distance of 6” is required for back side and
left side clearance. Thisensures proper ventilation
and prevents overheating which can lead to
advanced component failure and the riskof fire.

Installation Instructions 4
1. Some models come standard with shelves, shelf clips and
notched pilasters. Each shelf requires four clips. Attach the
shelf clips onto the pilasters by inserting its top hook into a
pilaster notch followed by the bottom hook. Do not use pliers
or other crimping tools to modify the shape of the shelf clips.
This will result in shelf mounting instability.
Shelf Installation
2. Place shelves on the shelf clips making sure all corners are
mounted securely and evenly with identical distance from the
unit’s floor and up. Always lay the back of each shelf down on
the rear clips before the front.
3. When removing a shelf, unmount the shelf from the shelf
clips. To detach the shelf clip from the pilaster, tilt up the shelf
clip until the bottom hook clears, followed by the top hook.

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 8
Everest units come as 115 volts, 60 hertz, single
phase.
Everest units in this family are equipped with a NEMA
5-15P plug. 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 with 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.
NEMA 5-15R

Operation9
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 interior light and evaporator fan motor is
controlled by a door switch for solid door models and
a rocker switch for glass door models.
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.

supply breaker may be switched off. Unplug the unit
and contact a licensed electrician for inspection and/
or repairs.
7. Troubleshooting Guide
In most cases, your Everest product may be exhibiting behavior that is typical of standard operation.
Observe the following when troubleshooting symptoms.
The compressor operates continuously or for
prolonged periods.
The condenser coil may be clogged with dust, grime or
debris. Clean it following the instructions in Chapter 6.
The door, drawer or gasket may not be sealing
properly. Check product placement in the cabinet as it
may prevent the door and drawers from fully closing. If
the gasket is loose, reattach.
The evaporator coil may be blocked with ice. Defrost it
following the instructions in Chapter 5. Normally,
evaporator coils will self-maintain with automated
defrost cycles. If the evaporator coil ices up frequently,
re-assess placement of food items in the cabinet as it
could obstruct cold air circulation. Food items must not
touch the wall or floors of the cabinet and stay within
the boundaries of the shelf to prevent blockage of air
flow.
The room’s ambient temperature may be higher than
86°F (30°C). Provide ample ventilation or additional
cooling to the room or relocate the unit to a larger
space with lower ambient temperature.
The unit may be installed in close proximity to heat
sources such as ovens, stoves, heaters or direct
sunlight. Relocate the unit away from these sources.
The unit may be installed without clearance or proper
ventilation. This forces the compressor to operate
constantly in order to maintain cabinet temperature.
Provide additional exhaust vents and observe the
clearance allowance specified in Chapter 2.
