The HY-6E has two independent cavities, each
with its own base-mounted steam generator.

Equipment Description
Your Groen HY-6E HyPerSteam Convection Steamer is
designed to give years of service. It has two stainless
steel cavities (cooking chambers) which are served by
twin, independent atmospheric steam generators which
are electrically-heated. A powerful blower circulates the
steam in each cavity to increase heating efficiency.
Each cavity holds up to three steam table pans (12" x 20"
x 2½"). An 18 gauge stainless steel cas
e encloses the
cavities, the steam generators and the control
compartment that houses electrical components. Door
hinges are reversible (the doors may be set to open from
the left or right). Operating Controls are on the front
panel.
HY-6E steamers are equipped with fully electronic
controls and a button-activated, preprogrammed CLEAN
cycle. The On-Off switch is a touch pad control, and the
distinctive symbol for steam is integrated into the panel
design.
The drain system includes a spray condenser, which
helps keep steam from escaping down the
condensate
drain.
Water Conditioning

OM-HY-6E
It is essential to supply the steam generator with water
that will not form scale or cause corrosion. Even
though the steam generator is engineered to minimize
scale formation and the effects of corrosion, their
development depends on the quality of your water and
the number of hours per day you operate the equip-
ment.
Most water supplies are full of minerals and chemicals
which are not suitable for use in a steam generator.
Water quality varies from state to state and city to city.
It is necessary that you know and understand the
quality of the water you are using. Your water utility
can tell you about the minerals and chemicals in your
water. The water going to the steam generator should
be within these guidelines
Water Pressure 30-60 psi
PH 7 to 9
Hardness less than 60 ppm
TDS 30 to 60 ppm
Chlorine and Chloramine less than 0.1 ppm
Total Chloride less than 30 ppm
Silica less than 12 ppm
Undissolved Solids less than 5 microns
1. Do not rely on unproven water treatments which are
sold for scale prevention or scale removal. They
don’t always work. The best way to prevent scale is
to supply the purest possible water (30 - 60 ppm
TDS).
2. If your water contains scale-forming minerals, as
most water does, use a well-maintained water
softener. Whether an exchangeable softener
cartridge or a regenerating system is chosen, a
regular exchange schedule is essential.
3. Installing a water meter between the softener and
the steamer will provide an accurate gauge of water
use, and will help determine when to exchange
cartridges or regenerate the softener. Using a water
softener will provide longer generator life, higher
steam capacity, and reduce maintenance require-
ments.
4. If you notice a slowdown in steam production, have
the unit checked for scale build-up. Heavy scale
reduces the unit’s ability to boil water and can even
cause heating elements in the steam generator to
overheat and burn out.
