INSTALLATION AND OPERATION INSTRUCTIONS

FOR

BOTTOM MOUNT REFRIGERATORS AND FREEZERS

INSPECTION

When the equipment is received, all items should be carefully checked against the Bill of Lading to insure all crates and cartons have been received. Do not sign the freight bill clear until the freight has been properly inspected for damage. All units should be inspected for damage including concealed damage by uncrating immediately. If any damage is found, it should be reported to the carrier at once, noted on the Bill of Lading and a claim should be filed with the carrier. This equipment has been inspected and tested in the manufacturing facility and has been crated in accordance with transportation rules and guidelines. The manufacture is not responsible for freight loss or damages.

INSTALLATION

The unit has been secured to the shipping base with four bolts. Remove these bolts and separate the unit from the shipping base. Locate the casters or legs found inside the unit. Attach the casters or legs to the unit base by screwing them into the threaded fittings that were used to secure the shipping base. Use the wrench provided to tighten the casters to the unit. The casters with the brakes should be installed on the front of the unit. For proper drainage of condensate, the unit should be level when placed in its permanent location. Leveling shims are in cluded in the accessories package in the cabinet. Loosen the casters and insert shims between caster and bottom of the unit. Retighten the caster.

The exterior of the cabinet and doors have been protected by a plastic covering. Peel this protective covering before installation. After removing the covering, clean the interior and exterior surfaces of the unit with soap and water and a rinse with clean water. Do not use chlorinated cleaners on the surfaces as they can cause corrosion.

If the door(s) have come out of alignment during shipping they will need to be adjusted. This can be accomplished by opening the door(s) and loosening the screws that hold both the top and bottom hinges to the cabinet. After adjusting the door so it is aligned correct, tighten the screws to securely hold the hinges and door(s) in place.

The shelves and self clips are packaged inside the unit. Install the shelf clips on the pilasters inside the unit and set the shelves on the clips. The shelves are adjustable in ½” increments.

The refrigeration system located at the bottom of the unit requires free air access for proper operation. Allow a minimum of seven inches between the back of the cabinet and the wall. Do not locate the unit next to heat generating equipment or in direct sunlight.

Confirm that the proposed electrical outlet has the correct voltage, frequency and current carrying capacity for the requirements of the unit. This information is noted on the data plate on the inside left wall of the unit. The unit should be isolated on a circuit. Do not use an extension cord to get power to the unit. Improper electrical installations will void the compressor warranty.

2. REFRIGERATION CYCLE

2. REFRIGERATION CYCLE 2. REFRIGERATION CYCLE

Mechanical refrigeration is accomplished by continuously circulating, evaporating, and condensing

a fixed supply of refrigerant in a closed system. Evaporation occurs at a low temperature and

pressure while condensation occurs at high temperature and pressure. Thus it is possible to

transfer heat from an area of low temperature(i.e., refrigerated compartment) to an area of high

temperature(i.e., surrounding of refrigerator).

CONDENSER

COMPRSSORCAPI LLARY TUBE

EVAPORATOR

THE BASE REFRIGERATION CYCLE

THE BASE REFRIGERATION CYCLETHE BASE REFRIGERATION CYCLE

Beginning the cycle at the evaporator inlet the low pressure liquid expands, absorbs heat

(so refrigerator inner-cabinet is cooled), and evaporates, changing to a low pressure gas at the

evaporator outlet.

The compressor pumps this gas from the evaporator, increases its pressure, and discharges the

high pressured- temperature gas to the condenser.

The condenser lets high pressured- temperature gas emit the heat(so surrounding of the

condenser is warmed) in order to make it condense.

The capillary tube prevents high pressured- temperature gas from entering the evaporator

in order to lower the pressure in the evaporator and control the flow of refrigerant into the

evaporator automatically.

Eventually the desired air temperature in refrigerator inner-cabinet is reached, the thermostat

(temperature controller) will break the electrical circuit to the compressor motor and stop

the compressor.

-A6 -

As the temperature of the air rises, the thermostat(or controller) remakes the electrical circuit.

SUCTION PIPE (INNER-CABINET)

The compressor starts, and cycle continues.

Sensor assembly consists of T-sensor (lead wire: orange) and D-sensor (lead wire: blue). The T-sensor is used for cabinet temperature control and the D-sensor is used for defrost control.

The resistance of the sensor varies depending on temperature.

If you Immerse the sensor in a glass containing ice water for 2 minutes and then check for the resistance between sensor leads, the normal reading is 7.88㏀ (T-sensor) / 30㏀ (D-sensor).

OPERATION

Once the unit is connected to the proper power supply, the display panel will be lit for two (2) seconds followed by a beep, and then the cabinet temperature will be displayed and the compressor will start to run. The compressor is running whenever ‘comp’ is lit on the display. If the cabinet temperature is higher than 68˚F (refrigerator) or 14˚F (freezers) the display will read <Hi> and lower than14˚F (refrigerator) or -50˚F (freezer) the display will read <Lo>. If the unit does not start immediately, check the power switch located on the bottom of the top grill. If the cabinet temperature is below 14˚F (freezer) or 50˚F (refrigerator) when the unit is plugged in there will be a three minute delay before the compressor will start.

The interior light will come on when a door is opened.

Whenever a door is opened the door open light on the display will be lit and the evaporator fans will stop. The fans will start three seconds after the door is closed. If a door is open for more than 30 seconds, the door open alarm will beep two times. If a door is open more than 60 seconds, the alarm beeps five times and if open more than five minutes the alarm will beep continuously.

The electronic control has an alarm function to remind the operator to periodically clean the condenser coil. The condenser coil will collect dust and debris during normal operation. If left unclean, this will lead to poor performance, high energy consumption and possible compressor failure. Warranties do not cover failures related to condenser cleaning. At 6 month intervals the display will blink “CL” and the buzzer will sound to remind the operator to clean the condenser coil. After one hour the buzzer will stop but the display will continue to blink “CL”. Refer to the ‘MAINTENANCE’ section of this manual to learn how to clean the condenser coil. The electronic control can be reset to normal operation by pressing the ‘Mode’ and ‘Verify’ buttons at the same time for five seconds. Depending on conditions, the condenser coil may require more frequent cleaning.

MAINTENANCE

Cleaning Beginning with the initial installation, the interior surfaces of the cabinet should be periodically cleaned with a solution of warm water and baking soda. This solution will remove any odors from spillage that has occurred. The exterior of the cabinet should also be cleaned frequently with a commercial stainless steel cleaner, glass cleaner or mild soap solution. Do not use chlorinated cleaners on the stainless steel surfaces.

The door gaskets should be cleaned in place with a mild soap solution to extend their life.

The shelving can be and cleaned in a sink with a mild soap solution and a soft bristled brush.

Condenser Coil Prior to cleaning the condenser coil disconnect the unit from power. Periodic cleaning of the condenser coil will aid the heat transfer of the refrigeration system and increase its efficiency. To accomplish this, remove the lower front grill from the cabinet. The condenser coil is located behind the grill. Use a soft bristled brush to remove any dirt particles that are on the fins of the condenser coil. Use a vacuum cleaner or compressed air to remove the loosened particles. Replace the front grill and reconnect the unit to power. Failure to clean the condenser coil can lead to performance loss and compressor failure.
