VL SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS

7.Once the correct pressure has been set, turn the power switch OFF, replace the adjustment screw cap and 1/8 inch NPT plug (pressure tap) on the outlet side of the valve.

8.Check for proper operation.

DIRECT STEAM MODELS

These models consist of a pressure regulator and gauge that run off a buildings potable steam supply. The regulator used will be of the adjustable type and should be set for a discharge pressure of 10 psi. The maximum input pressure to the regulator should be 15 psi. Incoming power (120VAC) for the compartment controls is supplied from a junction box in the base.

HEATER CONTACTORS

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.

The contactor can be serviced by removing the cover of the contactor box.

A noisy contactor (hum or chatter) is generally due to excessive dust or dirt on the armature pole faces or around the armature core preventing the magnet coil from pulling the armature into a completely sealed position. This can usually be corrected by blowing or wiping the pole faces clean. To inspect electrical contacts, remove cover at top of contactor by removing two screws which hold it in place. Replace contactor if the electrical contacts appear to be severely pitted or burned.

HEATING ELEMENTS

The steam coils on a regenerated type steamer are intended for use at a steam supply pressure of 15 psi maximum. A pressure regulating valve is available as optional equipment for steamers where a buildings steam supply pressure exceeds 15 psi. The regulator used will be of the adjustable type and should be set for a discharge pressure high enough for good steam generation. This pressure can be monitored by the supplied pressure gauge. The regulator should be set, only when steam is flowing (steam solenoid valve is open). If steam is heavy with condensate, install a ball float trap in the steam line before the pressure regulating valve.

WARNING: SHUT OFF THE STEAM SUPPLY BEFORE SERVICING THE UNIT.

To remove a steam coil, disconnect union in steam supply line to the coils and in the condensate discharge line from the coils. Remove header that supplies steam to coils by disconnecting union at each coil. In same way, remove coil condensate collection header. Remove four bolts clamping each coil flange in place and pull coil forward. Use a new flange gasket when replacing coil. The faces that mate with gasket must be clean.

Turn steamer power switch ON, allowing steam generation and, consequently, pressure to rise to normal operating level and then turn power switch OFF for a final purging of boiler and steam supply lines. Steamer is now ready for use.

WARNING: THE FOLLOWING STEPS REQUIRE POWER TO BE APPLIED TO THE UNIT DURING THE TEST. USE EXTREME CAUTION AT ALL TIMES.

1.Measure the voltage at the heating element terminals and verify it against the data plate voltage.

A.If voltage is incorrect, find the source of the problem.

B.If voltage is correct, check current draw (amps) through the heating element lead wires. See table below for proper values.

C.If current draw is correct then heating element is ok.

D.If current draw is not correct then replace the element and proceed to step 3.

NOTE: When replacing an element, always use a new gasket and ensure that the flange and tube surfaces which contact the gasket are clean. If removed element shows a pronounced scale build-up on its heating tubes, the other elements should be removed and mechanically cleaned to remove the scale. This will prolong their life. DO NOT immerse elements in a chemical solution to descale.

2. Check for proper operation.
