COMBITHERM INSTALLATION AND MAINTENANCE MANUAL #6004/18
COMBITHERM® INSTALLATION and MAINTENANCE
TRANSPORTATION
Upon receipt of the Combitherm Combination Oven-
Steamer, check the exterior of the shipping crate 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. Uncrate the unit carefully and inspect
for any transit damage. Immediately report any damage to
the delivering freight carrier.
The oven must remain on the pallet while being moved to
the installation site by fork-lift or pallet lift truck.
When removing the oven from the pallet to the
installation site, DO NOT LIFT at the condenser
housing. Care should also be used to prevent
damage to the drip-tray hanger permanently
mounted at the bottom of the oven door.
INSTALLATION SITE
HOOD INSTALLATION IS REQUIRED
In order to ensure proper ventilation, a minimum distance
of at least 6” (152mm) must be kept from the control panel
side [left] of the oven and any adjoining surfaces. In
addition to ventilation requirements, additional clearance
is needed for service access. A minimum distance of
18-inches (457mm) is strongly recommended.
Allow a minimum of 4” (102mm) from the right side of the
oven to allow the door to open to at least a 90° angle.
Fully opened, the door will extend up to a 225° angle. If
the oven is furnished with the retractable door option,
allow a minimum clearance of 6-1/2” (16cm).
Allow a minimum clearance of 4” (102mm) from the back
of the oven for plumbing connections.
Allow adequate clearance for the steam vent(s) located at
the top [right-rear] of the oven.
Do not install the oven adjacent to heat producing
equipment such as fryers, broilers, etc. Minimum
clearance recommended: 20” (50cm).
Place the Combitherm Oven on a stable, LEVEL horizontal
surface. For counter-top models, the oven stand must be
level. In addition, the overall height of the oven should
be positioned so the operating controls and shelves may be
conveniently reached from the front. Counter-top
installations must maintain 4" (102mm) minimum
clearance from surface by means of a Leg Extension
Assembly.
ALL INSTALLATION INSTRUCTIONS AND
REQUIREMENTS MUST BE STRICTLY OBSERVED.
IMPROPER CONNECTION OF THIS APPLIANCE
NULLIFIES ALL WARRANTIES.

WATER DRAINAGE
The oven must discharge through an indirect waste
pipe by means of an air gap. The drain thread is
1-1/4" NPT.
A union is required. Install a 1-1/4" (32mm)
diameter drain line. The drain line must always be a
positive gradient away from the Combitherm oven
and not more than 12" (305mm) before an air gap.
ATTENTION: In the U.S.A., this equipment is to be
installed to comply with the Basic Plumbing Code of
the Building Officials and Code Administrators
International, Inc. [BOCA], and the Food Service
Sanitation Manual of the Food & Drug
Administration [FDA]
If several units are to be connected to one drain pipe,
the dimensions of the pipe must be sufficient to allow
an unobstructed water drain system.
WATER SUPPLY
CONNECT TO POTABLE ( DRINKABLE) COLD WATER ONLY
WATER PRESSURE REQUIREMENTS: MINIMUM 45 PSI (3 BAR)
MAXIMUM 75 PSI (5 BAR)
Flush the water line at the installation site before connecting the oven to the water supply. A shut-off valve
and approved back-flow preventer must be installed when connecting the oven to the cold water intake. The
water supply line must be a minimum of 3/4-inch (19mm). A hose connector (
HO-22116) is supplied for
flexible hose connection to the cold water source. A water filtration system is recommended if the water
supply is between 7 and 9 grains of hardness. If water tests over 14 grains of hardness, the installation of a
water softener is stronly recommended.

COMBITHERM® CLEANING and MAINTENANCE
COMBITHERM INSTALLATION AND MAINTENANCE MANUAL #6004/18
PG. 16
Establishing a routine cleaning and maintenance schedule will help keep the oven running at top
operating efficiency and is an absolutely essential part of a comprehensive sanitation program.
Good equipment maintained and kept clean works better and lasts longer. PROTECT
YOUR INVESTMENT.
Daily Oven Cleaning
To be performed at the end of each production day or between production shifts.
Daily Steam Generator Flush
When operating the oven on a regular basis, the steam generator must be flushed once a day. This
procedure will prevent lime deposits and scale build-up from forming in the steam generator.
Weekly Steam Generator Back-Flush
Back-flushing the oven on a weekly basis prevents lime deposits and scale build-up from forming in the
entire steam generating system. It will flush the areas missed with the daily steam generator flushing
procedure. This procedure should be followed once a week, in place of the daily steam generator flush.
Monthly Decalcification
It is VERY important to decalcify the oven , particularly in areas with extremely hard water. This
procedure should be followed once a month, in place of the daily steam generator flush.
Daily Gasket Cleaning
It is important to prolong the life of the oven gasket by cleaning this item on a daily
basis. Routine cleaning will help protect the composition of the gasket from
deterioration caused by acidic foods. Remove pull-out gasket and wash in hot soapy
water or in the dishwasher. Always replace the gasket before cleaning the oven
interior or operating the oven.
Probe Usage and Cleaning
After each use of the CORE TEMP program mode, wipe the probe tip with a clean paper towel to remove food debris.
Follow by wiping the probe with a disposable alcohol pad. Return the probe to the proper door bracket position.
Probe Cleaning Procedures
1.
Remove all food soil from probe between loads and at the end of each production shift. Wipe
entire probe, cable assembly, and probe holding door bracket with warm detergent solution
and a clean cloth.
2. Remove detergent by wiping the probe, cable, and bracket with clean rinse water and a
cloth.
3. Wipe probe and probe bracket with disposable alcohol pad or sanitizing solution
recommended for food contact surfaces.
4. Allow probe and cable to air dry in probe holding door bracket.
5. Rewipe the probe with a disposable alcohol pad prior to inserting in a new food product.
Roll-In Cart/Food Trolley Cleaning
1. Remove food trolley to a cart wash area. Trolleys may be cleaned using any mild cleaning detergent and
warm water.
2. Hand wipe all framing, slides, drip pan, and base. Thoroughly clean debris from the casters. A spray
hose can be used for easier cart cleaning.
3. Remove detergent solution with warm water.
4. Wipe or spray with a sanitizing solution designed for use on metal and vinyl food contact surfaces.
5. Allow trolley to air dry.
