5.0 MAINTENANCE
COLD WATER CONDENSER
The steamer is equipped with a cold water condenser in the rear of the cooking chamber
which helps to condense the steam prior to discharge into the drain. The steamer freely
vents itself by the negative pressure created by the condensate water drainage. This
negative pressure prevents steam leakage around the door gasket and helps draw the
steam through the cooking compartment. Steam leakage at the door may indicate a
plugged or improperly installed drain.
REMOVAL OF SCALE DEPOSITS
It is recommended that your steamer be delimed once a month, or more often if
necessary.
Should your steamer develop a heavy buildup of lime scale deposits, use CLR.
Before beginning deliming procedures, ensure that water is not overflowing into the
cooking compartment.
The generator tank has a removable sealed tank cover. The main purpose of the
removable cover is for inspection of the interior of the tank for lime build up and easy
removal of large pieces of lime that will not flush out drain. Should the tank cover have to
be removed, check condition of sealing gasket before replacing cover. The hold down
bolts are to be tightened to 160 inch pound torque each.
WARNING: Read and follow instructions on the CLR bottle. Use plastic or
rubber gloves to avoid skin contact. If CLR comes in contact with skin,
rinse with clean water.
1. Drain steam generator by setting the main power switch to OFF. Set cooking timer
to “O".
2. Set the main power switch to DELIME.
3. Delime port (A) is located on left side at rear of unit. Unscrew hex plug from elbow to
allow CLR solution to be poured in using a tube and funnel. Pour in 28 ounces of
solution into the generator (pour slowly to avoid spillage). Remove tube and funnel.
4. Screw the hex plug back into the elbow so that it is sealed.
5. Turn main power switch to ON.
6. Allow steamer to remain in READY cycle for 1-1/2 hours, then turn main power
switch OFF and allow generator to drain.
