GAS CABINET BASE CONVECTION STEAMER, GCX-16, GCX-24
7.0 PERIODIC MAINTENANCE (Continued)
CAUTION: If burner does not shut off during blowdown,
immediately discontinue use of appliance and call for service.
Continue draining water for about fifteen (15) seconds, from control until water is clean.
Manually close valve. Recheck gauge glass. If water level has dropped significantly, wait for
the boiler to restore water level and pressure and repeat if necessary.
1. Observe that the water in gauge glass is clean and clear. Extreme murkiness in water
indicates inadequate water quality.
2. Safety valve should be tripped during operation once a week to assure that it functions
properly.
3. Keep all exposed cleanable areas of unit clean at all times
CAUTION: Take extra caution when blowing down water level
control or tripping safety valve as extreme hot water and live steam
are present.
REMOVAL OF SCALE DEPOSITS
This equipment should be installed with the Middleby TruH20 water treatment system which,
when properly maintained can provide a scale-free environment for your steamer. However,
because water quality can vary it is recommended that the steamer be checked every 90 to 120
days for scale build up. Regular maintenance should be carried out at this time.
DESCALING BOILER
If the boiler has been descaled, a new Anode should be installed in the boiler.
1. With boiler empty, close manual blowdown valve. If appliance is equipped with automatic
blowdown, turn water supply OFF to appliance. Turn power switch ON. This will energize
and close blowdown valve.
2. Remove 3/4" pipe plug from fitting on left front of boiler.
3. Insert appropriate hose or tube through fitting and pour in (½) half gallon (U.S.) of CLR
Descaling Solution or use the Optional Deliming Assembly DPA-1 available from your
dealer.
