C O M B I T H E R M ® I N S TA L L AT I O N RECEIVING & TRANSPORTATION Upon receipt of the Combitherm combination oven/steamer, check the exterior of the shipping carton for any physical damage that could result in damage to the contents. If the oven was not received from the carrier in an upright position, there is a stronger possibility of concealed damage. Remove the carton or uncrate the unit carefully and inspect for any transit damage. Immediately report any damage to the delivering freight carrier.
C O M B I T H E R M ® I N S TA L L AT I O N BASIC INSTALLATION SITE REQUIREMENTS H O O D I N S TA L L AT I O N I S R E Q U I R E D • Installation surface must be level. • Do not install adjacent to flammable surfaces. • Deep fat fryers or similar heat producing equipment must not be installed in the immediate vicinity of the hand shower. The oven must remain on the pallet while being moved to the installation site with fork lift or pallet lift truck. Do not tilt the oven.
C O M B I T H E R M ® I N S TA L L AT I O N POSITIONING ON SITE removing the oven from the pallet for ➤Before positioning on site, it is important to remove the drip tray to prevent damage to the tray caused by the lifting forks. The drip tray is fastened to the bottom of the oven with three sheet metal screws as illustrated. This requirement pertains to the following models. MODELS 6•10 ML 10•10 ML 7•14 ML 10•18 ML This step does not pertain to models 12•20 ML and 20•20 ML .
INSTALLATION REQUIREMENTS ■ Do not install oven adjacent to flammable 4" (102mm) surfaces. Strictly observe all local fire safety regulations. ■ In order to ensure proper ventilation, a minimum distance of at least 6-inches 18" (46cm) (152mm) must be kept from the control panel side [ LEFT ] of the oven and any adjoining surfaces. 4" (102mm) NOTE: In addition to ventilation RETRACTABLE DOOR OPTION: requirements, additional clearance 6-1/2" (165mm) is needed for service access.
C O M B I T H E R M ® I N S TA L L AT I O N ASSEMBLY REQUIREMENTS HAND SHOWER HOLDER Fasten the hand shower holder in the holes provided on the oven using the three (3) screws packaged with the holder.

C O M B I T H E R M ® I N S TA L L AT I O N WATER DRAINAGE The oven must discharge through an indirect waste pipe by means of an air gap. The drain thread is 1-1/4-inch (32mm) NPT. A union is required. Install a 1-1/4-inch (32mm) diameter drain line. The drain line must always be a positive gradient away from the Combitherm oven and not more than 12-inches (305mm) before an air gap. NOTE: In the U.S.A.
C O M B I T H E R M ® I N S TA L L AT I O N ELECTRICAL INSTALLATION ELECTRICAL CONNECTIONS MUST BE MADE BY A QUALIFIED ELECTRICIAN IN ACCORDANCE WITH APPLICABLE ELECTRICAL CODES.

C O M B I T H E R M ® I N S TA L L AT I O N INSTRUCTIONS TO BE PROVIDED TO OWNER/OPERATOR ■ INITIALS / DATE Owner/operator has been instructed on proper method of flushing the steam generator and safe procedures for handling the steam generator drain cap. ■ Owner/operator has been instructed on the importance of cleaning the oven along with proper cleaning procedures including automatic steam generator flush, daily cleaning of the interior, and monthly decalcification.
ELECTRIC COMBITHERM INSTALLATION CHECKLIST ® Use this list as a final check of oven installation conformance. Damage directly attributed to improper set up, installation, or cleaning can invalidate warranty claims. CLEARANCES: All clearances must conform with the standards set by Alto-Shaam as indicated in the installation manual. Standards include a minimum 20” (50cm) clearance from any heat-producing device such as an open burner range, flat top grille, fryer, steamer, etc.
I M P O R TA N T S A F E T Y P R E C A U T I O N S For safe release of the cooking compartment steam, initially open the door approximately 2" (50mm) only. Stand behind the door as the hot STEAM steam is released. DO NOT USE THE ATTACHED HAND-HELD HOSE TO SPRAY ANYTHING OTHER THAN THE INTERIOR OF THE COMBITHERM OVEN COMPARTMENT. AT NO TIME SHOULD THE EXTERIOR OF THE OVEN BE STEAM CLEANED, HOSED-DOWN WITH THE HAND-SPRAYER, FLOODED WITH WATER, OR FLOODED WITH LIQUID SOLUTION OF ANY KIND.
