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.

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. 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.
5. Do not place your hands under the unit when
moving it to avoid injury from sharp edges,
protruding parts or weight impact.
6. 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.
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.
8. 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.
9. 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 balance.
Install the front leg stabilizers for units that come
standard with it to ensure proper door / drawer
functions and unit stability.
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. This may compromise the unit’s
electrical components and lead to electrical
shocks or the risk of fire.
12. Select a location that will not expose the
unit to extremely dusty conditions. Environments
with high dust and debris content will significantly
hasten condenser coil and condenser coil air
filter blockage and will 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 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.
15. The unit is intended for indoor use only.
Outdoor use will cause a decrease in performance,
advanced component failure, and the risk of fire.
16. Ensure that the draft assembly is installed
before turning on the equipment. Refer to Chapter 2
for proper installation guidelines.

Keg Installation
1) Choosing the Nitrogen tank location
A) Cabinet Exterior: For Nitrogen tanks placed outside of the unit, it is necessary to drill a hole for
the Nitrogen port anywhere in the safe areas indicated in Chapter 2. Drilling outside of these areas will
cause irreparable damage to the refrigeration components and/or wiring.
B) Cabinet Interior: For Nitrogen tanks placed inside the unit, it is not necessary to drill a hole for the
Nitrogen port. This set up is possible depending on the model of the Direct Draw Keg Refrigerator and
the size of the Nitrogen tanks and coffee kegs.
2) Connecting the Nitrogen Line to the Nitrogen Regulator
A) Before proceeding, ensure that the shut off valve of the Nitrogen regulator is closed. The lever must
be perpendicular to the Nitrogen line if it is in the closed position.
B) Take one end of the Nitrogen line and push it up the Nitrogen regulator’s barb connector as tightly
as possible. Secure the hose to the fitting with the use of a clamp. The clamp must be positioned well
above the hose and fitting junction so as not to interfere with the valve operation.
C) If the Nitrogen tank is located outside the cabinet, feed the hose through the Nitrogen port that was
drilled into the wall of the unit.
3) Connecting the Nitrogen Regulator to the Nitrogen Tank
A) Before proceeding, ensure that the Nitrogen tank is filled and in the closed position.
B) Connect the Nitrogen regulator nut to the Nitrogen tank.
4) Connecting the Keg Coupler
A) Before proceeding, it is critical that the keg pull handle is closed in the up position.
B) Install the keg coupler on the keg’s neck junction. Turn clockwise to lock it in place.
5) Connecting the Nitrogen Line to the Keg Coupler
A) Take the open end of the Nitrogen line and push it up the keg coupler’s barb connector as tightly
as possible. Secure the hose to the fitting with the use of a clamp. The clamp must be positioned well
above the hose and fitting junction so as not to interfere with the valve operation.
The Nitrogen distributor can be used to share the single Nitrogen tank between multiple kegs.

Keg Installation ( continued )
6) Connecting the Coffee Line to the Keg Coupler
A) Before proceeding, remove any protective film or wrap from the keg coupler.
B) Attach the rubber washer to the coffee line hex fitting.
C) Connect the coffee line from the tower to the screw fitting on top of the keg coupler.
7) Tapping the Keg
A) Pull on the top handle of the keg coupler and push down until it locks in place.
8) Calibrating the Nitrogen Regulator
A) Keep the shut-off valve of the Nitrogen regulator closed while you open the valve on the Nitrogen tank.
B) Loosen the Nitrogen regulator adjustment nut with a pair of pliers. Twist the adjustment screw
counterclockwise all the way.
C) Slowly turn the Nitrogen regulator adjustment screw until the desired pressure is shown on the
output pressure gauge.12 PSI is the recommended pressure for most situations. Some conditions
such as site altitude or coffee variety will dictate specific pressure settings. Some regulators
designed for coffee are turned clockwise to increase output pressure and counterclockwise to
decrease output pressure.
D) Open the shut-off valve on the Nitrogen regulator while keeping the main switch parallel to the
tubing. The keg will audibly pressurize as gas flows through the regulator to the keg coupler. The output
needle will momentarily drop as the pressure equalizes before returning to the original position it was
set to.
E) Pull on the ring of the keg coupler’s pressure relief valve to allow gas to vent. This will help achieve
a more accurate reading on the output pressure gauge.
F) Recheck the output pressure on the regulator. If necessary, readjust following step 8C until the
desired pressure is achieved. Finish any adjustment to the regulator with a brief pull on the pressure
relief valve to ensure an accurate reading on the output pressure gauge.
9) Placing the Keg
A) Position the keg in the cabinet interior. Ensure that no hoses are pinched or crushed.
The Nitrogen distributor can be
used to share the single Nitrogen
tank between multiple kegs.

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 14
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 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

Operation15
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.
