INSTALLATION, OPERATION & MAINTENANCE MANUAL
OPERATION
Operation of the CombiGuard Water Filtration System
is completely automatic provided adequate water
pressure is maintained. The requirements to
maintain dependable operation include outlet
pressure monitoring, filter changes at recommended
intervals, and service documentation including a log
of filter replacement.
MAINTENANCE
Routine maintenance of the CombiGuard system
includes the periodic replacement of the sump
O-rings and the replacement of filter cartridges at
recommended intervals. Filter changes are necessary
to maintain optimum performance of the
CombiGuard filter system in order to provide full
benefit to Combitherm oven operation.
NOTE: If the filter change frequency is less than 6 months due to a pressure drop, it may be necessary to
add additional pre-filtration. Contact the Alto-Shaam service department for assistance.
FILTER CARTRIDGE REPLACEMENT:
1. Turn power to the Combitherm oven to the
OFF position.
2. Turn OFF water to the CombiGuard System by
closing the inlet ball valve
3. Press the RED BUTTON

PRESSURE GAUGE MONITORING
It is important to periodically monitor the pressure
gauge located on the CombiGuard unit. If the needle
on the gauge enters the red zone, it is usually an
indication that the filters have become clogged with
sediment. Ideally, the pressure gauge should never
drop into the red zone.
FILTER CHANGE FREQUENCY
Replacement of the filter cartridge (FI-26356) must
be made whenever any of the following apply:
•Six (6) months have passed since system
installation or the previous filter change.
•PRESSURE GAUGE needle enters the red zone.
•PRESSURE GAUGE drops below the pressure
required for equipment operation.
•WATER FLOW is reduced.
7. Inspect the O-ring
distorted. Wet the O-ring with water (only) and
make certain it is properly positioned before
replacing the filter housing. The filter housing
should only be tightened by hand.
8. Slightly open the inlet ball valve
trapped air, push and hold the red pressure
relief button
until a small amount of water is
visible. After the pressure button has been
released, fully open the ball valve.
9. When the water supply inlet valve has been
