This cabinet is NOT a re-thermalizing or cooking appliance. Dimension: Weight: (W)x31.75 (D)x69.7 (H) 130lb/65kg Approx. UNPACKING Examine the interior and exterior to determine whether any damage has occurred during shipping. If so, notify the carrier immediately to file a damage claim. All Win-Holt equipment is carefully tested and inspected prior to shipment. When accepted for delivery by carrier, the responsibility for safe arrival at the destination is assumed by the carrier.

MAINTENANCE The equipment has been designed to require minimum maintenance and has been constructed to meet NSF and electrical safety standards. Non-toxic chemical cleaners or mild detergents are recommended for cleaning. DO NOT use steel wools of any kind. Steel wool particles will work into the grains of the metal causing corrosion.

7 Trouble Shooting Basic operation When the power switch is turned ON, the blower motor and temperature display is always on. If the Heat/Proof switch is set to Heat only, the heat thermostat is active and can be set to achieve the required temperature. When the Heat/Proof switch is set to Proof both the Heat and Proof thermostats are active and can be adjusted to achieve the required temperature and humidity. The indicator lights cycle on/off as the heat and proof thermostats cycle on and off. PROBLEM No lights or temperature display High temperature Low temperature Low humidity High humidity Cause Check power switch is ON. Check is cabinet is plugged in. Breaker might be tripped. Power switch could be bad. Thermostat is set too high. Faulty thermostat Faulty blower. Set point is too low. Door being opened too often. Door is not sealing correctly. Blower is faulty. Humidity thermostat set too low. Heat thermostat set too high. Door is not sealing properly. No water in the pan. Humidity thermostat set too high. Heat thermostat set too low. 5
