Equipment Description Your Groen HY-3E or HY-5E 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 (HY-3E) or five (HY-5E) standard steam table pans. A 1.
Water Conditioning 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 equipment. 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.
Installation & Start-Up WARNING THE UNIT MUST BE INSTALLED BY PERSONNEL WHO ARE QUALIFIED TO WORK WITH ELECTRICITY AND PLUMBING.

Pans should be filled to about the same levels, and be even on top. 3. Open the door and slide the pans onto the supports.
Cleaning WARNING DISCONNECT THE POWER SUPPLY BEFORE CLEANING THE OUTSIDE OF THE STEAMER. To keep your HY-3E or HY-5E Steamer in proper working condition, use the following procedure to clean the unit. This regular cleaning will reduce the effort required to clean the steam generator and cavity. KEEP WATER AND CLEANING SOLUTIONS OUT OF CONTROLS AND ELECTRICAL COMPONENTS. NEVER HOSE OR STEAM CLEAN ANY PART OF THE UNIT.
Cleaning CAUTION NEVER LEAVE A CHLORINE SANITIZER IN CONTACT WITH STAINLESS STEEL SURFACES FOR LONGER THAN 30 MINUTES. LONGER CONTACT CAN CAUSE CORROSION. DELIMING STEPS (Use Touch Pad) STEP 1 Press ON/OFF to turn steamer off. Open door. STEP 2 Let cavity cool for 5 minutes or longer. While cool, wipe out cavity. Close door.
