combitouch® 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.

water supply and drains:

Verify hook-uptotwo (2) separatecold water supply lines with a3/4" (19mm) water connection supply line. Verify inlet water pressure is at a minimum of 30 PSI (2.8 bar). Maximum water pressure is not to exceed 90 PSI (6 bar). Verify drain diameter of1-1/2"(41mm) with a positive descending slope, and with a 2" (51mm) air gap which is free of obstructions before connection to the site drain. Verify 1/8" (3.2mm) pitch to 10' (305cm) of drain line.

important: Alto-Shaamhas listed Water Quality Requirements in the installation manual for this equipment. It is the responsibility of the end user to have the water connected to this appliance tested to ensure these standards are met before putting the oven into use. Failure to meet these standards will void the warranty if damage to the oven is found to be related to water quality.

error codes

this section is provided for the assistance of qualified technicians only and is not intended for use by untrained or unauthorized service personnel. if your alto-shaam® unit is not operating properly, check the following before calling your authorized alto-shaam service agent:

check that unit is receiving power. circuit breaker turned on?

do not attempt to repair or service the oven beyond this point. contact alto-shaamfor the nearest authorized service agent. repairs made by any other service agents without prior authorization byalto-shaamwill void the warranty on the unit.

when the oven malfunctions, an error code will appear in the display.

PRESS THE START ICON TO ACKNOWLEDGE THE ERROR.

The icons that begin to flash represent operational modes that are still usable. when the oven fault is corrected, the combitherm will return to normal operation.

ventless hood option

The Ventless Hood option is factory installed directly on the top of the Alto-ShaamCombitherm oven. The hood is designed to vent clean air back into the kitchen, filtering vapors and grease. Ahigh-powerfan draws steam and fumes into the hood intake and out the top surface exhaust vent. Fumes and vapors are circulated through filters draining the condensation through a drain at the rear of the hood. An activated charcoal filter cleans the air before venting it out the top of the hood.

condensate drain

A ventless hood condensate drain line to the floor drain must be installed. The 3/4" NPT thread connection is found at the back of the hood. The drain line must always be a positive gradient away from the Combitherm.

filter door latch

Using a coin or screwdriver, turn to open; reverse procedure to close and latch.

Hood and oven will not operate unless this is closed properly.

operation

1Turn the ventless hood power knob “ON”.

2Wait five seconds, then press the “combi reset” button.

3Turn the Combitherm oven power “ON”.

1 Ventless Hood Power Knob

2 Emergency Latch Release: This release is to be usedONLY if the timed latch mechanism is not working or in the event of a power outage. Repeated use of the emergency release may damage the switching mechanism.

3 Indicator Lights: If the indicator lights do not illuminate, the filters may be missing or not properly aligned. Check them for proper positioning. Ventless hood and oven will not operate unless the hood is closed properly.

4 Combi Reset Button: The reset has to be used if the Combitherm oven is turned on before the hood or if the hood was opened. It resets the pressure switch circuit and provides power to the Combi control circuit. This switch must also be used to reset hood controls after any problem with the filters, or the improper latching of the ventless hood door.

5 Charcoal Filter: The charcoal filter should be inspected for contaminant's on a regular basis. Replacement must be made at a minimum of three month intervals — more often if heavy contaminant's are visible or if the filter no longer controls odors.

To remove the filter, pull and slide out while holding the bottom housing. When replacing the filter, make certain the air flow arrow(s)

point toward the hood fan, and that the filter is replaced in the three-sidedmetal frame provided with the hood.

FI-24114(VHes-5);FI-24102(VHes-10)

6 Timed Latching Mechanism:In order to evacuate steam and grease-laden air from the oven interior, this mechanism prevents the operator from fully opening the oven door for 25 seconds to one minute. The mechanism automatically disengages at the end of a pre-set time allowing full door extension.

7 Grease Filter: Cleaning frequency should be based on oven usage with a maximum of two weeks between cleaning if the oven is used fornon-greaseladen products or steam applications only. Grease laden products require cleaning frequency of at least once a week.

Remove the grease filter by pulling it straight out of the housing. Place the filter in the dishwasher or wash separately by placing in hot, soapy water until all grease and particles have been removed. Rinse thoroughly. Allow the filter to air dry before reinstalling.

To replace the grease filter, the air flow arrow on the filter casing should be pointing toward the hood fan.
