IMPORTANT
• Confirm that the ambient temperatures are within the tolerances allowed.
• Do not locate next to heat generating devices.
• Confirm the unit is level.
• Do not use an extension cord to connect the unit to power. Use of an extension cord will void all warranties.
• Do not tamper with the ground pin on the power cord.
• Confirm that the power receptacle has a properly wired ground connection.
• The unit must be isolated on a power circuit.
• Confirm the power supply matches the require power supply noted on the serial plate.
START-UP AND OPERATION
Once the set-up and installations requirements are complete the Capsule Pak ECO is ready to start-up. Once
the power cord is connected to a live power outlet and the power switch on the unit is in the on position the unit
will start running. The display will light up immediately but the unit may not start running for 1 minute. On a Low
Temperature Capsule Pak ECO the evaporator fans will not run until the evaporator coil has pulled down to 40°F.
Allow the unit to run for a minimum of two (2) hours and verify the walk-in is down to temperature prior to loading
with product.
TEMPERATURE CONTROL
Note: It is the installing contractors responsibility to check the operation upon start-up and make any
necessary temperature adjustments as required for proper operation.
Capsule Pak ECO systems come equipped with an electronic control. The temperature control display and user
interface are located on the side of the system. The control comes pre-set to give walk-in air temperatures of
approximately 37°F for coolers and -10°F for freezers. Refer to the accompanying electronic control manual for
detailed instructions on adjusting the control parameters.
On dual compressor systems, there is a programmed delay from the start of the first compressor and the second
to reduce the start-up power surge on the power supply.
COOLER OPERATION
There is a programmed one-minute delay to start the system upon start-up. As noted, coolers come set at 37°F.
The control will shut the cooling off when it reaches the set temperature and re-start when the set temperature
plus the set differential (4) are reached. There is a minimum set point for the control of 30°F and a maximum set
point of 55°F. The control is pre-set to have a timed off cycle defrost every 6 hours. The defrost duration is 20
minutes. The evaporator fans will operate at high speed when the compressors are running and low speed when
the compressors are off.
FREEZER OPERATION
There is a programmed one-minute delay to start the system upon start-up. As noted, freezers come set at -10°F.
The control will shut the cooling off when it reaches this temperature and re-start when the set temperature plus the
set differential (5) are reached. There is a minimum set point of -20°F and a maximum set point of 10°F. The control
is pre-set to have a timed electric defrost cycles every 6 hours. The maximum defrost duration is 30 minutes.
The defrost is terminated by evaporator temperature first or time if the coil does not teach the temperature. The
evaporator fans are off during defrost and start when the evaporator reaches 40°F. After defrost the evaporator
fans will operate at high speed when the compressors are running and low speed when the compressors are off.
