Vantage 6000™ Series and Glass Door Merchandisers Reach-Ins Service and Installation Manual

Operation Information

Do not place hot pans on the white ABS liner. Do not throw items into the storage area. Failure

to heed these recommendations could result in

damage to the interior of the cabinet or the blower CAUTION coil.

After plugging the unit in, the unit will operate immediately.

Temperature Control Instruction

Refrigerators: A thermostat, located at the top of the refrigera- tor evaporator housing, controls the temperature in the box. The factory setting for the control is “4” and maintains about 38°F (3°C) in the box. Set toward “1” for higher temperature and toward “7” for lower temperatures.

Freezers: A thermostat, located at the top of the freezer on the right hand side of the evaporator housing, controls the temperature in the box. The factory setting for the control is “4” and maintains about -3°F (-19°C) in the box. Set toward “1” for higher temperature and toward “7” for lower temperatures.

Refrigeration cycle

During the refrigeration cycle, for a freezer, the timer supplies power to the temperature control, evaporator fan motors and activates the condensing unit as needed. The fan operates only during the refrigeration cycle. Any door being opened turns off the fan motors and turns on the interior light.

1)The temperature control allows for the coil clearing after each off cycle and before the compressor runs again.

2)Evaporator fan motors run continually on refrigerators only.

3)Interior lights are activated by the jamswitch when any door is opened.

4)The anti-sweat heater around each door opening cycles with the compressor.

Defrost Cycle

When defrost control goes into defrost, power to the condensing unit and evaporator fans is interrupted and the defrost heater is energized. The defrost heater warms the evaporator coil thereby melting all frost accumulated during the previous refrig- eration cycle. Once all frost is eliminated, the temperature of the coil continues to rise until it reaches 70°F (13°C). When this temperature is sensed by the defrost limit control, the defrost control switches to refrigeration mode.

If for any reason the timer remains in defrost for a period of time greater than 40 minutes, a back-up defrost termination is also provided. It can be changed by adjusting the electric control switches as shown on page 7.

Freezer Defrost Control

All freezers are equipped with an Air-o-tronics defrost timer for automatic defrosting of the evaporator coil. See page 7. The defrost timer cannot be adjusted to the time of day.

Operation

The electric defrost controller is preset at the factory to provide a defrost cycle every 6 hours (4 defrosts per day). If it is neces- sary to change the number of defrosts due to unusual operating conditions, it can be accomplished by adjusting switches as shown on page 7.

Even under the most severe operating conditions it should not be necessary to set the back-time greater than 60 minutes. Consult the factory if complete de-icing of the coil is not accomplished.

Unit loading

When loading the top shelf, maintain 4” of space between the fan guard and product. Do not allow product to pass stop bar on the back of the shelf. No product should be placed between the back shelf supports and center ribs in order to maintain good airflow. Failure to keep this space can cause inconsistent food temperature from top to bottom.
