All standard units are equipped with an adjustable thermostat located on the lower right-hand side of the evaporator coil, on the inside of the walk-in. All walk-in cooler freezer units are set at the factory to the temperature requested by the customer. Minor adjustments in operating temperature may be made to suit your needs. Polar King recommends that you do not set the temperature colder than required, as this will cause unnecessary power consumption.
Recommended temperature for a cooler ranges from +34°F to +37°F, unless specified otherwise, for special applications.
