OM/SM-HY-3E & HY-5E(CE)
Equipment Description
Your Groen HY-3E and HY-5E HyPerSteam Convection Steamers are 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 three (HY-3E) or five (HY-5E) standard steam table pans. A 1.5 mm thick 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.
Newer model HY-3E steamers and all HY-5E steamers, are equipped with fully electronic controls and a button-activated, pre-programmed CLEAN cycle. These units are readily identified by their unique control panels, with touch pad controls, and the distinctive symbol for steam is integrated into the panel.
Both units are distinguished by the addition of a “fuse box” which allows the operator to 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 steamer holds five standard 305 mm x 508 mm x 64 mm deep pans.
The HY-3E steamer holds three standard 305 mm x 508 mm x 64 mm deep pans.
Inspection and Unpacking
The HY-3E or HY5E 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.
CAUTION
THIS UNIT WEIGHS 82 KG (HY-3E) OR 105 KG (HY-5E). YOU SHOULD GET HELP AS NEEDED TO LIFT THIS WEIGHT SAFELY.
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.
When starting installation, lift the unit straight up off the skid. Check packing materials to make sure loose parts such as the condensate drip tray are not discarded with this 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 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:
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. 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.
A BSPT connection is provided at the rear of the steamer.

Operation
WARNING
ANY POTENTIAL USER OF THE EQUIPMENT SHOULD BE TRAINED IN SAFE AND CORRECT OPERATING PROCEDURES.
A. Controls
Operator controls are on the front right of the unit. The control panel has the following touch pads and indicator lights. (Your controls may have either words or the symbols shown below):
The ON/OFF touch pad gets the HyPerSteam ready for use, or shuts it off.
The READY indicator light shows that the steam generator is at standby temperature and the cavity is hot enough to begin steaming.
The CLEANING indicator lights when the unit is operating in the cleaning mode.
The SERVICE indicator light shows when the water level probes have stopped working, and need to be cleaned (normally an indication of lime deposits).
When one probe is not working, the SERVICE light flashes briefly every few seconds. When both probes fail, the light will flash continuously and the beeper will sound.
The HI TEMP indicator light comes on when the steam generator is too hot.
The unit will automatically shut off, and cannot be turned on again until it has been serviced.
The TIMING indicator light stays on when the timer is running.
The CLEAN touch pad is used to start the automatic 50 minute cleaning cycle.
The timer is used in three ways:
1In the OFF position the steam generator stays at a low boil or “holding” temperature.
2When a cook time is set, the unit steams until the timer reaches OFF. The steaming stops, a red light comes on and a beeper sounds.
3With the timer turned to the ON position, the unit steams continuously. The green light stays lit. The steamer will not time down.
B. Operating Procedure
1.Press the ON switch/pad for the steamer. The steam generator will fill, and heat until the READY light comes on. (About 10 minutes.)
2.Load food into pans in uniform layers. Pans should be filled to about the same levels, and be even on top. The maximum allowable weight of food is 9.8 Kilograms (21.6 lbs.) Per pan.
3.Open the door and slide the pans onto the supports. If you will only be steaming one pan, put it in the middle position.
4.Close the door. With the READY indicator lit, take one of the following steps:
!If you want to steam the food for a certain length of time, set the timer for that period. The timer will automatically run the steamer for the set time and then turn it off. A red light will come on and a beeper will sound. Steam production stops.
!To steam continuously, turn the timer to the manual ON position. A green light will come on. The unit will continue steaming until you stop it by turning the timer to OFF. When steaming continuously YOU MUST CONTROL STEAMING TIME.
