6. To stop manual mode ste aming, press the TIMED (top) end of the TIMED/MANUAL rocker

• If the steamer will be used again in a few m inutes shut the door to maintain the cooking
compartment temperature.
• If another use is not planned for more than half an hour, l eave the cooking compartment
door slightly open to reduce interna l pressure while the steam is condens ing and
cooling.

Down and Cleaning Procedures.
SECTION 5: SHUTDOWN AND CLEANING PROCEDURES
A. STEAM GENERATOR BLOWDOWN
(1) Power Off (Automatic Blowdown)
Blowdown occurs automatically when the steamer is turn ed off at its ON/OFF switch. During
blowdown, the steam generator drain s olenoid is rinsed with fresh water, and the boiler is
drained. Blowdown at frequent intervals helps decrease mineral buildup in the steam generat ors,
and reduces the frequency of descaling and other maintenance.
(2) Blowdown Frequency
The supply water quality determines how oft en blowdown must be performed. The higher the
feed water, total dissolved solids, and particula te, the more frequently blowdown must be
performed. A determination should be made at the time of installation whether additional
blowdown frequency will be required as part of the daily maintenance based on the water quality
analysis done as part of the installat ion. This information should be not ed in the daily
maintenance program developed for the equipm ent. If the local water supply meets the minimum
supply water quality standards, observe the fol lowing guidelines to establish proper blowdown
scheduling.
• For units without a water treatment system , blowdown must be performed after every 4
hours of operation and at the end of e ach shift.
• For units with a water treatment system, b lowdown must be performed at the end of each
shift.
WARNING
SEVERE BURNS may result from exposur e to steam.
