MAINTENANCE
WARNING: THE STEAMER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING OR SERVICING THE STEAMER.
WARNING: THE COOKING COMPARTMENTS CONTAIN LIVE STEAM. STAY CLEAR WHILE OPENING EACH DOOR.
WATER TREATMENT SYSTEM
A water treatment system is recommended for steam generators. Refer to your supplier's manual for normal maintenance procedures for proper
BOILER BLOWDOWN
At least once daily, after the steamer boiler has been in operation, press [ O ] to blow down the boiler.
BOILER PRESSURE RELIEF VALVE
At least once every day, check the pressure relief valve to verify that it is functioning properly. The valve is located on the top left side of the boiler (Fig. 3 or 4, page 17). Trip the pressure relief valve when the steam gauge shows 4 psi or above. When steam escapes, release the valve.
DOOR GASKETS — VHX24, VHL2 & VHL3 SERIES STEAMERS
If the door gasket is nicked or cut, it must be replaced. Damage to the gasket sealing surface will cause steam leakage.
If a leak occurs in one corner only and the gasket appears serviceable, turn the stainless steel screw on the gasket plate adjacent to the leaking corner
WATER LEVEL GAUGE
Check the water level gauge sight glass daily. The correct water level is approximately 1" (2.5 cm) of water visible in the water level gauge sight glass. Extremely murky water in the sight glass indicates bad water conditions. The boiler should be blown down. If conditions persist, have the boiler inspected and cleaned by your local
FLUE
Annually, when the steamer is cool, check the flue and clear any obstructions.
INSPECTION OF BOILER INTERIOR
An access plate to inspect the boiler interior is provided for the state boiler inspector and authorized service personnel. The frequency of boiler inspections may vary from state to state, but are generally required every 12 months. Each time the boiler access plate is removed, the gasket must be replaced with a new gasket to prevent leakage.
