MAINTENANCE
GENERAL
The Hatco Electric Steamer ovens are designed for
maximum durability and performance, with minimum
maintenance.
CLEANING
Hatco recommends cleaning the Electric Steamer
after each days use. Allow the steam oven to cool
down to a safe temperature before cleaning.
NOTE: Do not close the door after cleaning until the
inside oven cavity is completely dry.
NOTE: Unplugging the appliance from the power
outlet will erase all menu programs and require
reprogramming of the unit.
WARNING
To ensure safe and proper operation additional
cleaning may be required depending upon
products being thawed and local codes applying
to sink thawing techniques.
WARNING
This appliance is not jet-proof construction. To
assure safe and proper operation do not use jet-
clean-spray to clean this appliance.
NOTICE
Do not use a steam cleaner to clean the outside
of this appliance. Pressurized steam could
cause permanent damage to the surface and
penetrate the electrical components causing the
appliance to short circuit.
NOTICE
Do not use harsh chemicals such as bleach or
cleaners containing bleach. Also avoid the use
of scouring pads, hard brushes, or steel wool as
they may damage the surface of the appliance.
NOTICE
Cleaning and sanitizing is recommended at the
end of each days use.
NOTICE
Use only non-abrasive cleaners with non-
abrasive sponges or cloths. Abrasive cleaners
could scratch the finish of your unit marring its
appearance and making it susceptible to soil
accumulation.
NOTICE
Do not use cleaning products containing
aliphatic compounds as these could cause the
seals to swell.
NOTICE
Ensure the water tank is empty after each days
use to prevent sediment build up in the
appliance.
NOTICE
Use only vinegar or citric acid based descaling
agents or descaling tablets to descale the
appliance.
Oven Interior
Removing the side runners from the inside of the
oven cavity will make cleaning the oven interior
easier.
1. Pull the side runner toward the steam oven
opening, and remove the side runner from the
oven wall. (See Figure 6.)
2. With a mild solution of household dish soap and
water, use a non abrasive sponge or cloth to
wipe the interior clean. Use the same solution to
wipe the side runners, roof seal, drip channel,
inside of the door, and the independent water
cavity. (Side runners may be cleaned in a
dishwasher if available.)
NOTE: If steam oven interior is discolored from bad
water quality, use a proprietary wet cloth and a citric
acid based descaling agent to remove stains.
NOTE: The water drain floating disc and cover will
require use of a periodic cleaning agent to remove
water deposits.
3. Wipe the oven interior with clean water and
thoroughly dry. Ensure no cleaning product
residue is remaining on the steam oven.
NOTE: The door seal can become porous and
cracked over time. If this happens the door
assembly will need to be replaced.
4. Install the left and right side runners. Make sure
the rear tip of each runner engages the mounting
holes in the back of the cabinet, then slide the
mounting tabs over the locating pins and push
down to secure. (See Figure 6.)
