MAINTENANCE
NOTE: Auto boiler drain occurs when the power is
switched off. The drain valve will be turned on for 1
minute to drain all the water/descaling agent in the
boiler to the drip pan and drain hose. There may be
some “noise” from the drain valve when the boiler
runs out of water and is empty.
Oven Exterior
1. With a mild solution of household dish soap and
water, use a non abrasive sponge or cloth to
wipe the exterior clean.
2. Wipe the oven exterior with clean water and
thoroughly dry.

Boiler Cleaning
NOTE: Hatco recommends connecting a hose to the
drip pan for drainage.
NOTE: The amount of mineral content in the water
and how often the unit is operated will dictate how
often the boiler requires cleaning. It is
recommended that home users perform this
procedure monthly and commercial users perform
this procedure weekly. Hard water usage will require
that the boiler be cleaned more frequently.
1. Leave power cord connected to the power supply
and turn the unit off and allow to cool. The boiler
will now begin draining.
2. Remove any pans or racks from the inside.
3. Fill the water tank with proper mixture of citric
acid based descaling agents, or descaling tablets
and water or vinegar to descale appliance.
4. Turn unit On. Start the steam cycle for one
minute at 50°C.
5. When steam starts coming out, immediately
press the Start/Stop button to stop the cycle and
open the door to cool the unit. Descaling agent
will now stay inside the boiler tank. Allow
descaling agent to soak for 15 minutes.
6. Turn the power Off and the boiler will now drain
the descaling agent.
7. Repeat this procedure with water only, until
discharge is clear.
