VL SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS

Two slotted and square headed adjustment screws extend through the top of the switch case. A pressure scale and indicating pointers are visible through the sight glass window to indicate the approximate pressure setting. The adjustment screw directly above the right side pointer changes the cut-out (off) set point and the adjustment screw directly above the left side pointer changes cut-in (on) set point. Adjust the screw to obtain the proper cut-out (off) setting first, then adjust the other screw to obtain the proper cut-in (on) setting. Turn the screw clockwise to increase the pressure setting and counterclockwise to decrease the pressure setting. The pressure settings for each switch are listed below.

FILL AND COLD WATER

SOLENOID VALVES

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.

Check to assure the solenoid valve is receiving power. If the solenoid valve is receiving power but the valve is not opening, the coil may be malfunctioning. Replace the solenoid valve and check for proper operation. If the solenoid valve is receiving power and the valve appears to be opening but little or no water is flowing through it, then the valve ports may be clogged with debris or a valve component malfunctioning. To check solenoid valve further, follow the procedure outlined below.

Disassembly

NOTE: It is recommended that the valve be removed for cleaning as outlined in this procedure. This will prevent damage to the lines and fittings when the stem is removed from the body.

1.Remove the coil assembly from the valve stem by lifting up on the retaining cap at the top of the solenoid valve and sliding the metal cover plate off.

2.Clamp the body of the valve in a vise.

3.Mark a scribe line on the stem nut to the valve body for proper retightening.

4.Remove the stem locking nut to remove the stem from the valve body.

5.All parts are now accessible for inspection and cleaning.

NOTE: If internal solenoid parts appear to be damaged or worn, then replace the solenoid valve. Do not reuse damaged or worn parts. No internal solenoid parts are available as a service replacement.

A.Check rubber seal on bottom of plunger.

B.Check plunger spring.

C.Check O-ring in valve body.

D.Check ports in valve body.

6.Reverse procedure to install.

COMPARTMENT PRESSURE

ADJUSTMENT

Remove the left side panel from the boiler base to access the compartment pressure regulating valve. If the steamer is equipped with the compartment pressure regulating valve and the steamer is operating, set the pressure regulating valve to read 6 psi on the compartment gauge. Turn the hex head screw at the top clockwise to increase the pressure and counterclockwise to decrease. If the steamer is not equipped with the compartment pressure regulating valve, then the compartment will cycle at the same pressures of the boiler. A mechanical pressure relief valve serves as a safety backup control and is pre-set for a maximum of 8 psi.
