Once the unit arrives . . .
A certified electrician runs power from their (the customer’s) power source to the disconnect of the PLC unit which is mounted on the rear of the unit, or side opposite the door. Once connections have been made the electrician flips the breaker on the disconnect from OFF to ON.
The unit will then begin cycling on and cool down to the desired temperature that is set on the thermostat.
It is recommended that the customer wait until the temperature reaches the set point before loading with product.
