Power Off
To extend your boiler’s serviceable life, when the
machine is expected to sit idle for a couple of days, turn
power OFF and open the steam output to discharge
steam pressure in the boiler. Continue until the pressure
gauge reading falls to zero and steam discharge ends.
Once complete, empty and clean the water tray.
NOTICE:
Leave the steam output setting open when
steam discharges. Steam output should remain open
until the machine is turned on and hot water begins
dripping from the steam tube.

All sanitizing agents in the food zone must
comply with 21 CFR 178.1010. Sanitize all food
dispensing units periodically. All parts to be sanitized
must be cleaned first. Cleaning and sanitizing frequency
must follow state and local health department
regulations.
