OM-HY-3E
Equipment Description
Your Groen 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 electrically-heated. A powerful blower circulates the steam In the cavity to increase heating efficiency.
The cavity holds up to three steam table pans (12" x 20" x 2½"). 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 drain system includes a spray condenser, which helps keep steam from escaping from the chamber.
Inspection and Unpacking
The HY-3E steamer holds three standard 12"x 20"x 2-½" pans .
The HY3-E will be delivered completely assembled in a heavy shipping carton attached to a skid. On receipt, inspect the carton carefully for exterior damage.
CAUTION
SHIPPING STRAPS ARE UNDER TENSION AND CAN SNAP BACK WHEN CUT.
Carefully cut the straps around the carton 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.
Write down the model number, serial number and installation date and keep this information for future reference. Space for these entries is provided at the top of the Service Log in the back of this manual.
CAUTION
THIS UNIT WEIGHS 180 POUNDS (82 KG). YOU SHOULD GET HELP AS NEEDED TO LIFT THIS WEIGHT SAFELY.
When starting installation, lift the unit straight up off the skid. Check packing materials to make sure loose parts are not discarded with the material.
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 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:
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).
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.
4
OM-HY-3E
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.
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.
On the HY-3E, 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.
Installation and Start-Up
WARNING
THE UNIT MUST BE INSTALLED BY PERSONNEL WHO ARE QUALIFIED TO WORK WITH ELECTRICITY AND PLUMBING. IMPROPER INSTALLATION CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE TO THE EQUIPMENT. THE UNIT MUST BE INSTALLED IN ACCORDANCE WITH APPLICABLE CODES.
CAUTION
DO NOT INSTALL THE UNIT WITH THE RIGHT SIDE VENTS BLOCKED OR WITHIN 12 INCHES OF A HEAT SOURCE (SUCH AS A BRAISING PAN, DEEP FRYER, CHAR BROILER OR KETTLE).
TO AVOID DRAINAGE PROBLEMS, LEVEL THE UNIT FRONT TO BACK.
1. Electrical Supply Connection
A.Panel Removal
Open the wiring and control panel by removing two screws on the right side panel. Slide the panel forward, and set it aside.
B.Supply Voltage
The unit must be operated at the rated nameplate voltage, plus or minus 10 percent.
C.Phase Selection
Refer to the heater schematic (Pages 15 and 16) for wiring information.
CAUTION
THE UNIT MUST HAVE A SEPARATE GROUND WIRE FOR SAFE OPERATION.
D.Terminal Block
The terminal block for incoming power is located at the back of the control compartment.
5
OM-HY-3E
The ground terminal is located in the wiring compartment above the terminal block. Minimum size for the ground wire is 10 AWG.
E.Supply wire
To determine the type of wire you need for the power supply, find the operating voltage and phase on the unit data plate. Refer to the table provided on the next page or to the label on the unit’s back for the correct wire size and insulation temperature rating. The “Electrical Supply Connection” label on back right side of the unit gives directions for proper connection of the terminal block jumpers.
The wire specified has to be used, or the unit will not meet Underwriters Laboratories and National Electric Code requirements.
The knockout hole is sized for a 3/4 inch conduit fitting.
WARNING
TO AVOID DAMAGE OR PERSONAL INJURY, FOLLOW THE ELECTRICAL SCHEMATIC EXACTLY WHEN CONNECTING THE UNIT

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.
A ¾ inch R connector (garden hose type) is used to attach the water supply to the water inlet valve. The 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.
If you have the twin water connection option, put the treated water (softened) to the right intake (facing the rear of the unit), and untreated water to the left. Connections for both are made as described above.
3. Drain Connection
The HY-3E Steamer must be leveled front to back, or even pitched slightly to the rear by adjustment of the bulllet feet on the cabinet base.
A 1½ inch (38mm) ID hose may be attached to the drain pipe (supplied).
WARNING:
DO NOT CONNECT THE DRAIN DIRECTLY TO A BUILDING DRAIN.
There must be at least one-half inch 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. There must also be no other elbows or other restrictions between the unit drain and the two inch free air gap.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE RATED FOR BOILING WATER.
