OM-HY-5E/HY-3E
Equipment Description
Your Groen HY-5E or HY-3E HyPerSteam
Convection Steamer is designed to give years of
service. It has a stainless steel cavity (cooking
chamber) which is served by an independent
atmospheric steam generator which is electricallyheated. A powerful blower circulates the steam in the
cavity to increase heating efficiency.
The cavity holds up to five (HY-5E) or three (HY-3E)
steam table pans (12" x 20" x 2½" deep). A 16 gauge
stainless steel case encloses the cavity, the steam
generator and the control compartment that houses
electrical components. Door hinges are reversible
(the door may be set to open from the left or right).
Operating Controls are on the front panel.
The HY-3E steamer holds
three standard 12" x 20 x 21/2" deep pans [old model
shown].
Newer model HY-3E steamers (manufactured since
February, 1999) and all HY-5E units are equipped
with fully electronic controls and a button-activated,
pre-programmed CLEAN cycle. These units are
readily identified by their unique control panels. The
On-Off switch on older models has been replaced by
touch pad controls, and the distinctive symbol for
steam is integrated into the panel. The new models
also have fewer panel louvers on the right side.
The new model can be identified
by its unique control panel, and
fewer side panel louvers.
From the rear the newer HY-3E and all HY-5E units
are distinguished by the addition of a fuse box, which
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.
The HY-5E holds up to five pans.
Inspection and Unpacking
The Steamer will be delivered completely assembled
in a heavy shipping carton strapped to a skid. On
receipt, inspect carton carefully for exterior damage.
CAUTION
THE HY-5E WEIGHS 205 POUNDS (93 KG). THE
THE HY-5E WEIGHS 180 POUNDS (82 KG). YOU
SHOULD GET HELP AS NEEDED TO LIFT THIS
WEIGHT SAFELY.
CAUTION
SHIPPING STRAPS ARE UNDER TENSION AND
CAN SNAP BACK WHEN CUT.
Write 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
Service Log in the back of this manual.
Carefully cut the straps and detach the sides of the
carton from the skid. Pull the carton up off the unit.
Be careful to avoid personal injury or equipment
damage from staples which might be left in the carton
walls.
When starting installation, check packing materials
to make sure loose parts such as the condensate
drip tray are not discarded with this material.

OM-HY-5E/HY-3E
Water Conditioning
It is essential to supply the steam generator with water
that will not form scale. Even though the steam
generator is engineered to minimize scale formation,
scale development depends on the hardness of your
water and the number of hours per day you operate the
equipment.
In some areas, water is low enough in mineral content
to avoid scale formation. But 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 between 10 and 30 parts per million (ppm) total
dissolved solids (TDS) and should have a pH (acidity
rating) of 7.0 or higher. Please follow these simple
precautions:
New models have a fuse box mounted on
the rear.
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 (10 - 20 ppm TDS).
Since softener systems are typically sized by total
GPH (gallons per hour), the second intake could
reduce treatment requirements by up to 80%,
resulting in significant savings.
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.
On both the HY-3E and HY-5E, the twin water
connections are side by side on the rear of the unit.
When facing the back of the unit, the treated
(softened) water intake is on the right.
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 requirements.
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.
MINIMIZE SCALE PROBLEMS, BY USING AND
MAINTAINING A SOFTENER, AND BY CLEANING
THE STEAMER REGULARLY.
Groen Steamers are also available with an option for
two separate water intakes — one for the steam
generator (soft water), the other for the spray
condenser (untreated water). The steam generator
only uses 14 to 31% of a steamer’s water.
The optional second water connection can
reduce treated water requirements.

2. Water Connection(s)
Install a check valve to prevent back flow in the
incoming cold water line, as required by local
plumbing codes. Water pressure in the line
should be between 30 and 60 PSIG (210 and
420 kPa). If pressure is above 60 PSIG, a
pressure regulator will be needed.
Install the drain line with a constant downward pitch.
IMPORTANT: Do not allow water traps in the
line. A trap can cause pressure build-up in the
cavity, which may cause the door gasket to leak.
DRAIN LINE INSTALLATION
(OLDER MODELS WITH DRAIN BOX)
OPTION ONE: Use 1½” Drain Kit (P/N 118948) to
nearby floor drain, or from Stainless Elbow (P/N
092272), use “Radiator” Hose (rated at least 212oF),
and an additional clamp (P/N 073259).
A ¾ inch NH connector (garden hose type) is
used to attach the water supply to the inlet valve.
Minimum water feed line diameter is ½ inch
(13mm). Use a washer in the hose connection.
Do not allow the connection to leak, no matter
how slowly. For the twin water connection
option, treated (softened) water goes to the right
(facing the rear of the unit), and untreated water
to the left. Connections for both are made as
described above.
OPTION TWO: Using the hose (P/N 073254) and
two hose clamps (P/N 073259), connect 1½” copper
3. Drain Connection
Level the steamer front to back, or even pitch it
slightly to the rear by adjusting the bullet feet on
the stand or cabinet base.
A 2 inch (50 mm) ID hose may be attached to
the drain pipe (supplied).
WARNING:
DO NOT CONNECT THE DRAIN DIRECTLY TO A
BUILDING DRAIN. BLOCKING THE DRAIN IS
HAZARDOUS.
tubing to the floor drain. NOTE: Drain lines must be
pitched downward approximately ¼” per foot.
No water traps are allowed in the drain line.
There must be a free air gap between the end of
the hose and the building drain. The free air gap
should be as close as possible to the unit drain.

OM-HY-5E/HY-3E
(NEW MODELS WITHOUT DRAIN BOX)
From the Muller Brass coupling-reducer (P/N W1095), connect 1½”“ copper tubing to the floor drain.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR VERY HOT WATER.
For stacked units use Drain Kit P/N 125777.
Install the line with a constant downward pitch.
4. Factory Stacked Units
This section is applicable only if you are installing
factory-mounted stacked units. If you plan to stack
steamers yourself, whether purchasing a new one for
stacking or a kit to stack two units you already own,
you will require OM-HY-3E(S), RETROFIT
SUPPLEMENT (Part Number 121014).
Installing the (2) HY-3E, (3) HY-3E AND (2)HY-5E
stacked steamers is similar to installing a single unit.
The steamers are stacked and assembled at the
factory and delivered with the water connections and
drain hoses required for a single point connection.
a. Water Connection
As the drawing on this page shows, the same
water supply connection is used. At the water
inlet valve a ¾ inch NH connector (garden hose
type) is used for the water supply. If you have
the second water connection option, there are
two connections to be made. Treated water
(softened) is connected to the right valve fitting
(facing the rear of the unit) and untreated water
to the left valve fitting.
b. Electrical Supply Connection
Separate, individual electrical connections
will be required for each steamer in the stack.
We also strongly recommend that each
Steamer have its own branch circuit
protection.
c.
Proper Drain Line Connection — Drain Line
must have a constant downward pitch of at
least ¼” per foot. (3)HY-3E shown, but
connection is the same for all units.
Drain Connection
Steamers must be leveled front to back, or
pitched slightly to the rear by adjusting the bullet
feet on the cabinet or stand base.
A 1½ inch (38.1 mm) ID hose may be attached
to the unit drain. It must be rated for very hot
water.
WARNING
DO NOT CONNECT THE UNIT DRAIN DIRECTLY
TO THE BUILDING DRAIN.
Ensure that there is a free air gap between the end
of the unit drain and the building drain. This gap
should be as close as possible to the unit drain. Do
not allow elbows or restrictions between the unit and
the free air gap.

by lifting it up and toward the center of the cavity.
n. If the steamer will no longer be used, leave it off.
Otherwise, wait 10 minutes and turn it back on.
When the READY light comes on, the steamer is
ready for operation.
e. Wipe out the cavity. Make sure the drain holes
at the back of the cavity are clear of debris.
f.
(HY-5E and New Model HY-3E) Hold down the
CLEAN button while turning the steamer on.
Continue holding it until the CLEANING indicator
light comes on. Then release the button. After
five minutes, the beeper will begin to beep
rapidly. This is the signal to add de-limer descaler as shown.
If the CLEAN light (SERVICE light on new
models) stays on:
(Old Model HY-3E) Turn on the
steamer and pour two cups of
Groen Delimer Descaler (P/N
114800), Lime-A-Way® or
equivalent into the delimer port as
shown at right. (use a measuring cup or funnel to
help prevent spilling). Do not use
any de-limer that contains
chlorine.
b. Repeat steam generator cleaning.
a. Check that the water supply is on and that the
supply hose is not kinked. With the problem
corrected, turn the steamer off or 10 seconds
and then re-start.
g. Replace fan baffle partition and
close door.
h. (HY-5E and New Model HY-3E)
The cleaning cycle consists of a boiling clean
stage, a soak stage, and a rinse stage. The full
cycle takes about 50 minutes to complete.
(Older Model HY-3E) on,Set the timer for 10
minutes. If the CLEAN light comes repeat the
procedure with double the amount of delimer. If
the CLEAN light comes on again, call the
authorized Groen Service agent in your area.
(See listing enclosed with this manual).
i.
The process for de-liming your Steamer is simple,
tool-less and quick. Adding de-limer/de-scaler is
the same for all HY-5E and HY-3E steamers.
WEAR PROTECTIVE GLOVES AND EYE
PROTECTION FOR THIS STEP. When the
steamer beeper sounds, turn off the steamer
and open the door. After the fan has stopped,

Maintenance
The HY-3E Steamer is designed for minimum
maintenance, and no user adjustments should be
necessary. Certain parts may need replacement
after prolonged use. If there is a need for service,
only Groen personnel or authorized Groen

3. Adjust the latch pin to allow for changes that
might occur as the gasket ages.
a. Loosen the lock nut at the base of the latch
pin, then turn the latch pin ¼ turn clockwise,
and tighten the lock nut.
Always supply water with a low mineral count that
meets the standards outlined in the Water
Conditioning section of this manual.
b. After adjustment, run the unit to test for
further steam leakage.
c.
If steam or condensate is seen leaking from around
the door, take the following steps:
If there is still leakage, repeat the
adjustment.
d. Continue adjusting the pin clockwise until the
door fits tightly enough to prevent leakage.
1. Check the door gasket. Replace it if it is cracked
or split.
2. Inspect the cooking chamber drain to be sure it
is not blocked.
