a. Receiving Inspection

Upon receipt, check all packages and accessories or optional components including legs, casters,
and shelves.

b. Legs & Casters

Legs screw directly into the base. Caster are plate-mounted. To install casters, tip or raise the
cabinet one side at a time and remove the four hex head screws in each corner of the bottom.
Use these same screws to attach the mounting plate. Screw-on type legs simply screw into the
adapter nut provided in each corner of the bottom.

c. Leveling

To provide adequate condensate drainage and proper door alignment and operation. It is
necessary that the cabinet be level. Level cabinet from front to rear and from side to side with
leveling bolts, or leg inserts. This should be done after cabinet has been set in its final operating
position. The leveling bolts are the same bolts used to attach the wood base to the cabinet. BE
SURE THAT DRAIN HOSE IS ATTACHED AND DRAINING PROPERLY INTO EXTERIOR
CONDENSATE PAN LOCATED BEHIND BOTTOM GRILLE ASS’Y. THE HOSE COULD
POSSIBLE BE KNOCKED LOOSE IN TRANSIT.

d. Door Handles

Door handles with mounting screws are packed inside each cooler.
To mount handle, lift door gasket behind two holes in front and insert screws through the holes.
Attach handle, with offset away from cabinet corner, and tighten screws. (NOTE: It may be
necessary to adjust position of handle end mounts on handle bar to match hole spacing in door
frame.)

2. Operation

a. Electrical Supply and Connections:

Plug all standard models into 115 volts A.C. 60 cycle outlet. Low line voltage is often the cause
of service complaints. Check to see that the line voltage is 110 volts or more with the unit
running. Other motors or heavy appliances should not be used on the same circuit with the
cooler. When working on the inside of the cooler disconnect from electrical circuit for safety
reasons. CAUTION: If an extension cord is necessary, use only a three wire grounding type of
wire size 16 AWG or larger; do not exceed 20 ft. in length. The use of ungrounded cords or
overloaded circuits voids compressor warranty.

b. Initial Start-Up:

Turn Power on and check to verify that the condenser fan is running. On all Models, except
RI18, the defog fan and light switches are located on the blower housing front inside the
cabinet, the Defog Switch in “ON” position permits the Condenser Fan to run continuously for
maximum Door Defoging in high humidity locations.

c. Temperature Control:

Factory setting of temperature control is at No. 5 position (normal) which will maintain the
product at about 36°F.* For colder temperatures, turn knob clockwise one number at a time.
Excessive tampering with temperature control could lead to service difficulties. For operation
about 3000 ft. altitude, have thermostat adjusted by a qualified serviceman.

d. Condensate Disposal:

The evaporator blower housing serves as a pan to collect and direct the condensate to the
evaporator pan located behind the front grille. Air flow over the pan hastens condensate
evaporation so that external drain plumbing is not required.

3. Maintenance

a. Cleaning Cabinet Exterior:

Cabinets should be cleaned with a solution of mild soap and water. Do not use caustic soap or
abrasive cleaners, since these might damage the cabinet finish. If stainless steel surface becomes
discolored, scrub by rubbing only in the direction of the finish grain. Do not use steel wool.

b. Cleaning Interior Surfaces:

The inside of the cabinet is coated with baked-on vinyl (except stainless steel cooler). To clean,
use mild soapy water and cloth or sponge.

c. Condenser:

For efficient operation, it is recommended that the condenser coil and fans be cleaned every
3 to 6 months. Remove front grille for access. Vacuum clean front surface of coil thoroughly or
direct forced air through condenser fins. Failure to clean condenser can cause compressor
malfunction and will void warranty.

d. Evaporator Fan:

Evaporator pan should be cleaned periodically to prevent odors and maintain evaporating
efficiency. The pan contains wicks to assist evaporation and should be replaced periodically.

e. Evaporator Housing:

If internal parts (e.g. fans, control) are to be serviced, lower housing as shown in (Fig 5). Make
certain to remove drain tube before lowering housing.

Bi-pin Fluorescent Lamp Installation /Verification

Prior to applying power to the unit, verify that all lamps are properly installed and fully engaged in
the lamp holders.

Proper lamp engagement is achieved by rotating the la mp 90° from its inserti on position until it
"snaps" or "clicks" into place.

Visual verification can be made on units without safety shields by using the identification mark on the
end of the bulb. Properly installed bulbs will have the m ark centered between the "hal ves" of the
lamp holder.

On units with shields, the identification mark cannot be seen. Physically verify that the lamp has been
rotated and locked into place.

See pictures below.

Caution: Improperly installed lamps may cause damage to the lighting circuit.
Beverage-Air shall have no liability whatsoever for equipment or component failures or other
damages or losses which arise as a result of improper install ation.

REFRIGERATION SYSTEM SERVICE AND ANALYSIS

CHART

!! REFRIGERATION SYSTEM

The Refrigeration System consists of a hermetically sealed compressor and

finned evaporator and condenser.

!! CONDENSER

The condenser has wide finned spaces, which allow more air passage with less dirt or dust accumulation. The condenser still
requires periodic cleaning for maximum efficiency.

!! CONDENSER FAN MOTOR

The condenser fan motor assembly is mounted between the condenser and the compressor. Air is drawn through the condenser,
over the body of the compressor and out the rear of the unit compartment.
The motor is wired to cycle with the compressor but will continue to operate should the compressor cut out on the overload. (The
motor is permanently lubricated; therefore, oiling is not required).

!! DRIER

The drier is installed in the system just before the capillary tube. Its purpose is to trap minute particles of foreign material and
absorb any moisture in the system.

!! LI!UID CONTROL AND HEAT EXCHANGE

Liquid refrigerant control to the evaporator of the system is accomplished by the use of a capillary tube. This capillary tube is
soldered to the suction line to form a heat exchanger which subcools the liquid refrigerant to maintain high efficiency within the system.

REFRIGERATION SERVICE

!! EVACUATION

Moisture in a refrigeration system is directly or indirectly the cause of more problems and complaints than all other factors
combined.
When large amounts of moisture are present, system freeze ups will occur. Even in minute amounts, moisture will combine with
refrigerants to form an acid. The corrosive action of this acid forms sludge, which will plug the lines and drier.
Since most field type vacuum pumps cannot pull a low enough vacuum to remove all moisture from the system, it is recommended
that the system be triple evacuated, breaking each time with dry refrigerant nitrogen. Use care to purge air from the charging hose when
breaking the vacuum.

!! CHARGING REFRIGERATION SYSTEM

Since capillary tube systems have small critical refrigerant charges, we recommend that a field charge either be weighed in or put in
from a portable charging cylinder. After maximum vacuum has been obtained as detailed above, attach charging cylinder to the system
line making sure to purge air from hose with refrigerant. With the unit running, allow refrigerant to run slowly into the system until the
desired charge is reached. When using Refrigerant Blends it is recommended to liquid charge into the high side of the system with the
initial charge and then any remaining charge can be put into the suction side; however, care must be taken to meter the remaining
amount into the low side so as not to cause excess liquid to go into the compressor.

OVERCHARGE
When the cabinet has pulled down to operating temperature,
an indication of an overcharge is that the suction line will be
cooler that normal with the compressor running. Running
time will be higher than normal. Suction line will sweat or
frost.
Reclaim excessive refrigerant from the system very carefully
in small amounts waiting several minutes for the system to
balance.

UNDERCHARGE
An undercharge or shortage of refrigerant will result in any of
the following:

1.! Lower than normal head pressure.

2.! Lower than normal suction pressure.

3.! Excessive or continuous operation of compressor.

4.! Higher than normal cabinet temperature.
