VL SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS

THERMAL SWITCH - PREVENT

AND AUTOMATIC MODELS

The load compensator is a thermal switch in a stainless steel housing that screws into a 3/8 NPT fitting (newer models) on the left side wall of the compartment. The switch contacts should close when the compartment temperature reaches 180￿F, supplying power to the steam exhaust solenoid valve, pilot light and cooking timer motor.

1.Newer Models

A.This switch is NON-ADJUSTABLE. Check to see if the switch is operating properly as described below. If the switch is suspected to be malfunctioning, replace it and check for proper operation.

2.Older Models

D.If the cooking cycle is started normally, but the red light and timer do not come on or an abnormal amount of time elapses before they come on, then the load compensator is set too high. Also, if the timer stops, the red light goes out, and the buzzer does not sound after the compartment has exhausted the steam or if the time is set as usual for the product and the product is overcooked or if the time is set as usual for the product and the product is overcooked.

E.If there is too short a time between starting and the red light coming on, or if it comes on immediately, the load compensator is set too low. Also, if the time is set as usual for the product and the product is undercooked.

A.The switch can be adjusted by turning the slotted screw. Turn the screw clockwise to lower the closing temperature and counterclockwise to raise the closing temperature. Check the operation of the switch as described below. These models are ½ NPT.

The correct adjustment or verification of the load compensator can best be made by using a digital thermometer and thermocouple to sense the compartment temperature.

1.Position the thermocouple near the exposed bulb of the load compensator inside the compartment.

2.Close and seal the compartment. Pull the steam control arm handle forward, set the timer and turn the compartment power switch ON.

3.Monitor the thermocouple temperature, and adjust or verify (as applicable) the load compensator temperature.

A.The red light of the compartment switch should light when the thermocouple reads 185 ±7 ￿F.

B.After the cooking cycle ends and the compartment temperature lowers, the thermal switch should then re-open at 165 ±7 °F.

C.If the load compensator can not be adjusted correctly or the temperature is out side the allowable limits, then replace thermal switch and check for proper operation.

WATER LEVEL GAUGE

ASSEMBLY

1.Close the valve at the top and at the bottom of the gauge assembly.

2.Unscrew the packing nuts at the top and bottom of the glass tube.

3.Slide the glass tube upwards, until the bottom of the tube is clear of the fitting and lift it out.

4.Reinstall the tube and use new sealing washers. Do not over tighten the packing nuts, it could break the gauge glass.

5.Open the top and bottom valves fully.

6.Check for proper operation.
