• Replace all electrical box covers, housings, etc.

• File a copy of this manual for future reference.

11

Section 3

Operation

• The Drop-In refrigeration systems are of the draw through design. The walk-in air is drawn into the supply air grill,

through the evaporator coil, and discharged out the return air grill into the walk-in. Any interruption or obstruction of

the supply or return air streams will result in unsatisfactory operation of the system.

• Coolers: When powered on, the evaporator fan(s) run continuously, even during defrost cycles, and the

• condensing unit will cycle on/off to maintain the walk-in temperature.

• Freezers: When powered on, the evaporator fan(s) run continuously except when the system is in defrost and for a

short period after the defrost cycle is complete. The condensing unit will cycle on/off to maintain walk-in

temperature.

NOTE: Walk-in temperatures will elevate above the set point during defrost cycles (approximately 30 – 45 minutes, 4 times

per day) but will return to the set point once the defrost cycle is complete.

Thermostat

•

The body of the thermostat is mounted inside the condenser compartment on both Top Mount and Side Mount

models.

•

The sensing bulb is placed in the return air stream inside the evaporator compartment.

•

The thermostat on Top Mount models can be accessed by removing the louvered front panel.

•

The thermostat on Side Mount models can be accessed by removing the left side panel on the condensing unit

assembly.

Air Defrost Thermostat Electric Defrost Thermostat

Do not block the supply and return air grills or the air space around the air grills. Keep plastic wrappings, paper, labels, etc.

from being airborne and lodging in the grills. Failure to keep the air grills clear will result in unsatisfactory operation of the

system.

• Access Setpoint mode by pressing and holding the button until tS (Temperature setpoint) displays on the

screen.

• Use the up and down arrows to scroll through the available setpoints.

• Press to view the current setting.

• Use the up and down arrows to change the setpoint.

• Press and hold the button to confirm each setpoint change.

• Press the button to escape.

13

Electric Defrost Timer (Freezers)

Defrost Time Clock

•

The defrost timer clock must be set to the correct time at initial start-up and after any power interruptions.

•

Set the clock by rotating the clock face until the correct time is at the arrow on the face of the timer.

•

The switch is programmed by pushing the captive trippers to the inner ring for the entire period the load is to be

turned “ON”.

•

When a tripper is pushed to the outside, the switch is in the “DEFROST” position.

•

Each defrost tripper represents 15 minutes of defrost time.

•

The timer is factory set for four defrost cycles daily at the following times: 4:00AM, 10:00AM, 4:00PM, and

10:00PM. Each defrost cycle is programmed for 30 minutes duration.

•

The defrost times can be changed to initiate at periods of low activity.

•

A setting of two to four defrost cycles per day is typical. For heavier frost loads, additional cycles may be required.

•

The timer starts the defrost cycle automatically at the predetermined times.

NOTE: If the defrost termination thermostat fails to close, the fail safe setting on the timer will terminate the defrost cycle.

When the defrost cycle begins:

• The compressor and evaporator fan motors will stop.

• The evaporator coil heaters will activate and increase the coil temperatures above 32°F/0°C, melting the frost and ice.

• NOTE: Walk-in temperatures will elevate above the set point during defrost cycles (30 minutes, 4 times per day)

but will return to the set point once the defrost cycle is complete.

• When the defrost time is complete or the evaporator coil warms to approximately 55°F/13°C, the compressor will

start the refrigeration cycle but the evaporator fan(s) will remain idle until the evaporator coil temperature is at or

below freezing.

• Once the evaporator coil temperature reaches approximately 30°F/-1°C, the evaporator fan(s) will activate.

• The system operates in the refrigeration cycle until another defrost cycle is initiated by the timer.

14

Air Defrost Timer (Coolers)

•

The defrost timer is incorporated into the Air Defrost Thermostat. There is no separate Air Defrost Timer.

•

The defrost timer is factory set for four defrost cycles daily at the following times: 4:00AM, 10:00AM, 4:00PM, and

10:00PM. Each defrost cycle is programmed for 30 minutes duration.

•

The defrost times can be changed to initiate at periods of low activity.

•

The timer starts the defrost cycle automatically at the predetermined times.

•

A setting of two to four defrost cycles per day is typical. For heavier frost loads, additional cycles may be required.

When the defrost cycle begins:

• The compressor will stop but the evaporator fan(s) will continue to run.

• Air is pulled across the evaporator coil without refrigerant running through the system. The coil temperature to

increases above 32°F/0°C melting the frost and ice.

• The system remains in defrost through the duration programmed on the timer. Once the duration is complete,

the compressor activates and refrigerant starts cycling through the system.

• The system operates in the refrigeration cycle until the next defrost cycle is initiated by the timer.
