Equipment Description

Your Groen HY-5E or HY-3E HyPerSteam
Convection Steam er is designed to give years of
servi ce. It has a stainless steel c avity ( c ook ing
chamber) whic h is served by an independent
atmospheri c steam generator which i s el ec tricall y ­heated. A powerf ul blower circul ates the steam in
the cavity to increase heating effici enc y .

The cavity holds up to five (HY-5E) or thr ee ( HY - 3E )
steam table pans (12" x 20" x 2½ " deep) . An 18
gauge stainless steel case encl oses the cavity , the
steam generator and the control compartment that
houses electrical components. Door hinges are
rever sible (the door m ay be set to open from the left
or right) . Operating Contr ols are on the front panel.

HY-3E and HY-5E steamers are equipped with f ully
electronic controls and a butt on- ac tiv ated, pre­programmed CLEAN cycle. These units are readily
identified by their unique control panels. The On­Off switch is operated by t ouc h pad c ontrols, and
the disti nc tive symbol for st eam is integrat ed into
the panel. T he new models also have fewer panel
louvers on the right side.

The HY- 3E st eamer holds three
standard 12" x 20" x 2½ ” st eamer
pans.

From t he rear HY-3E and HY-5E units are
distinguished by the addition of a fuse box, whi c h
lets operators change fuses without removing
panels.

The drain system on all models includes a spray
condenser, which helps keep steam from escaping
from the chamber and cools drain water.

Inspection and Unpacking

The Steamer will be delivered completely
assembled in a heavy shipping car ton strapped to a
skid. On receipt, inspect carton carefully for exterior
damage.

CAUTION
SHIPPING STRAPS ARE UNDER TENSION AND
CAN SNAP BACK WHEN CUT.

Caref ul ly cut the straps and detach the si des of the
car t o n f r om the ski d. P ull t he cart on up of f t he un i t .
Be careful to avoid personal injury or equipment
damage from staples which might be left in the carton
walls.

The HY-5E holds up to five pans.

CAUTION
THE HY-5E WEIGHS 230 POUNDS (104 KG).
THE THE HY-3E WEIGHS 180 POUNDS (82 KG).
YOU SHOULD GET HELP AS NEEDED TO LIFT
THIS WEIGHT SAFELY.

Wr ite down the model number, serial number and
installation date. Keep this information for reference.
Space for these entries is provided at the top of the
Serv ice Log in the back of this manual.

When starting instal lation, chec k pac k ing materi als
to make sure loose parts such as the condensate
drip tray ar e not discarded with thi s material.

Water Conditioning

It is essential to supply the steam generator with water
that will not form scale. Even though the steam
generator is engi neer ed to minimize scale formation,
scale dev elopment depends on the hardness of y our
water and the number of hours per day you operate
the equipm ent.

Most water supplies are full of minerals which form
scale. It is this scale which could lead to an early
component failure.

Your water utility can tell you about the minerals in
your water. The water going to the steam generator
should have more than 10 to 30 part s per million
(ppm) t otal dissolved solids (TDS) and should have a
pH (acidity rating) of 7.0 or higher. Please follow
these simpl e pr ec autions:

1. The best way to prevent scal e is to use a Groen
PureSteem™ Wat er Treatment S y stem which has
been specifically designed for Groen steamers
and combination ov ens. Do not rely on
unproven water treatment systems sold for
scale prevention and rem oval. They are not

specifically designed to work with Groen
steamers and combination ovens.

Models built sin ce 1998 have a fuse box
mounted on the rear.

On both the HY-3E and HY -5E, the dual water
connections are side by si de on the rear of the unit.
When seen from from the back of the unit, the
treated (softened) water intake is on the right.

2. A well-maint ained water treatm ent system and a
regular cartridge replacement schedule is
essential.

3. Using a Groen PureSteem™ Water Treatment
System will provide longer steam generator/boiler
life, higher steam capacity, and reduce
maint enanc e requirements.

4. If you notic e a sl owdown in steam production or
an increase in deliming, have the steamer
checked for scale build-up. This could be an
indicat ion that the water tr eatment cart r idges need
replacing. Heavy scal e r educ es the unit’s ability to
boil water, and c an even cause component failur e.

MINIMIZE SCALE PROBLEMS BY USING AND
MAINTAINING A SOFTENER AND BY CLEANING
(DELIMING) THE STEAMER REGULARLY.

The optional second water connection can
reduce treated water requirements.

Branch Circ uit Protection

Each Steamer, including individual units of
stacked models, should have its own branch
circuit protection and ground wire. Current

and power demands for each unit are as shown
on Page six.

IMPORTANT: Do not allow water traps in the
line. A trap can cause pressure bu ild-up i n the
cavity, which may cause the door gasket to leak.

4. Factory Stacked Units

2. Water Connection(s)

Install a c hec k valve to prevent back f low in the
incoming cold water line, as required by loc al
plumbing codes. Water pressure in the li ne
should be between 30 and 60 PSIG and must
deliver a flow rate of 1.5 to 3.0 gallons per
minut e. If pressure is above 60 PSIG, a
pressure regulator will be needed.

A ¾ inch female NH connec tor (garden hose
type) is used to attach the water supply to the
inlet valve. Minimum insi de diameter of the
water feed line is ½ inch. Use a washer in the
hose connection. Do not allow the connection to
leak, no matter how slowly. The dual water
standard connecti on, treated (soft ened) water
goes to the right ( seen from the rear of the unit ) ,
and untreated water to the left. Connections for
both are made as shown on Page Five.

3. Drain Connection

Level the steamer front to back, or pitch it
slightly to the rear (maximum ¼ inch) by
adjusting t he bullet f eet on the stand or cabinet
base.

A 2 inch [HY-5E] or 1½ inch [HY-3E] ID hose
may be att ached to the drain pi pe ( suppl ied).

WARNING:

DO NOT CONNECT T HE DRAIN DI RECT L Y T O
A BUILDING DRAIN. BLOCKING THE DRAIN IS
HAZARDOUS.

This section is applicable only if you are installing
factor y-stacked units. If you plan to stac k steamers
yourself , whether purchasing a new one for stacking
or a kit to stack two units you already own, you will
require O M-HY-3E(S), RET ROFIT SUPPLEMENT
(Part Number 121014). These instructions are also
valid for stac k ing HY-5E steamers.

Install ing stacked steamers is similar to installi ng a
single unit. The steamers are stack ed and
assembled at the factory and del ivered with the
water connections and drain hoses required for a
single point connection.

A. Water Connection

At the water inlet valve a ¾ inch female NH
connector (garden hose ty pe) is used for the
water supply. The dual water connection has
two connections to be made. Treated water
(softened) is connected to the ri ght val ve fitting
(looking from t he r ear of the unit) and untreated
water to the left fitting.

B. Electr ical Supply Connec tion

Separate, i ndividual electrical connections
will be required for each steamer in the
stack. Each St eamer must have its own
branch circuit protection.

C. Drain Connection

Steamers must be lev eled front t o back, or
pitched to the rear (maximum ¼ inch) by
adjusting t he bullet f eet on the cabinet or stand
base.

There must be a free air gap between the end of
the hose and the buil ding drain. The free air
gap should be as close as possible to the uni t
drain. T her e must also be no other elbows or
other restri c tions between the unit drain and the
free ai r gap.

CAUTION
DO NOT USE PLASTIC PIPE. DRA IN MUST BE
RATED FOR BO ILING WATER.

Install the drain line with a constant downward pitch.

For HY-3E a 1½ inch and for HY-5E a 2 inch ID
hose may be attac hed to the unit drai n. It must
be rated for boiling water.

WARNING

DO NOT CONNECT THE UNIT DRAIN DIRECTLY
TO THE BUILDING DRAIN.

Ensure that there is a free air gap bet ween the end
of the unit drain and the building drain. This gap
should be as close as possible to the uni t drain. Do
not allow el bows or restri c tions between the unit and
the free air gap.
