Fire Fuel Shut-Off

(optional feature)

Operating Instructions

ctric

Ele

Actuation of the fire control system per the submission drawing will trip all circuit breakers and controls equipped with
the fire-fuel shut-off feature and de-energize the corresponding outlets. After the fire control system is returned to
normal operation conditions, these circuit breakers will be de-energized until the circuit breakers are reset.

Gas

Actuation of the fire control system per the submission drawing will stop the gas flow to all gas operated equipment.
After the fire control system is returned to normal operating condition, the button marked gas reset must be
depressed. This will reopen the gas solenoid valve(s) and allow gas to flow to all gas operated equipment.

IMPORTANT NOTE After the gas system has been reset, all pilot lights must be re-lit.

Remote Status Indicator Lights

These lights are located remotely from each connection plate; however, they are interconnected to each connection
plate and show circuit breaker ON or OFF status.

Ventilator Light Switch (Optional)

The ventilator light switch is located on the control panel. Be sure that the ventilator light switch circuit breaker,
which is located next to the light switch, is in the ON position.

cord and plug assembly. After the cord and plug assembly is connected, equipment may be turned ON.

2. The connection plate consists of the following:

a. Point-of-use circuit breaker
b. Outlet
c. Indicator Light

3. To energize the outlet, turn the circuit breaker to the ON position.

NOTE Upon initial start-up, the circuit breakers may occasionally require a “break in” procedure. Turn the circuit

breakers OFF and ON several times.

Plumbing Connections

Installation

1. If system has field joint(s), plumbing must be connected at the joint(s) before attaching main service.

a. Connect corresponding pipes by aligning unions and tightening securely.

2. Connect all plumbing stub-ins to the main lines. Provide all necessary nipples, couplers, unions etc. to
make neat and proper connection.

3. Connect all hose assemblies to the appropriate equipment as shown on drawing. Provide all necessary ells
and nipples to make neat and proper appearance. (See hose installation instructions Page 9).

4. Check all plumbing for leaks and tighten as required.

5. Connect hood wash system (if provided) to spray nozzles in hood.

5. Replace all access panels.

Gas Valve Operation

Normally Closed: Valve is closed when solenoid is de-energized; open when energized

Maintenance

WARNING:

To prevent the possibility of death, serious injury or property damage, turn off electrical power, depressurize
valve, extinguish all open flames and avoid any type of sparking or ignition. Vent hazardous or combustible
fluid to a safe area before servicing the valve.

NOTE: It is not necessary to remove the valve from the pipeline for repairs.

Cleaning

All solenoid valves should be cleaned periodically. The time between cleanings will vary depending on the medium
and service conditions. In general, if the voltage to the coil is correct, sluggish valve operation, excessive noise or
leakage will indicate that the cleaning is required. In the extreme case, faulty valve operation will occur and the valve
may fail to open or close.

Care and Cleaning of Stainless Steel Equipment

Contrary to popular belief, stainless steels ARE susceptible to rusting and pitting.
Corrosion on metals is everywhere. It is recognized quickly on iron and steel as unsightly yellow/orange rust.

Such metals are called “active” because they actively corrode when their atoms combine with oxygen to form
rust.

Stainless steels are passive metals because they contain other metals, like chromium, nickel and manganese
that stabilize the atoms.

Chromium provides an invisible passive film that covers the steel’s surface acting as a shield against corrosion. As
long as the film is intact and not broken or contaminated, the metal is passive and stainless. If the passive film of
stainless steel has been broken, equipment starts to corrode. At its end, it rusts.

The Enemies of Stainless Steel
There are three basic things which can break down stainless steel’s passivity layer and allow corrosion to occur.

1. Mechanical Abrasion - Steel pads, wire brushes and scrapers are prime examples of things that will
scratch a steel surface.

2. Water and Deposits - Water has varying degrees of hardness. Depending on the area you live in, you may
have hard or soft water. Hard water may leave spots, and when heated, leave deposits that will break down
the passive layer and rust stainless steel. Other deposits from food preparation and service must be
properly removed.

3. Chlorides - Chlorides are found nearly everywhere. They are in water, food and table salt. Some of the
worst chloride perpetrators come from household and industrial cleaners.

Here are a few steps that can help prevent stainless steel rust and pitting.

1. Use the proper tools.

When cleaning stainless steel products, use non-abrasive tools. Soft cloths and plastic scouring pads will
not harm steel’s passive layer. Stainless steel pads also can be used but the scrubbing motion must be in
the direction of the manufacturers’ polishing marks.

2. Clean with the polish lines

Some stainless steel comes with visible polishing lines or “grain”. When visible lines are present,
always scrub in a motion parallel to the lines. When the grain cannot be seen, play it safe and use a
soft cloth or plastic scouring pad.

3. Use alkaline, alkaline chlorinated or non-chloride containing cleaners.

While many traditional cleaners are loaded with chlorides, the industry is providing an ever-increasing
choice of non-chloride cleaners. If you are not sure of chloride content in the cleaner used, contact your
cleaner supplier. If your present cleaner contains chlorides, ask your supplier if they have an alternative.
Avoid cleaners containing quaternary salts; they can attack stainless steel and cause pitting and rusting.

4. Treat your water.

Though this is not always practical, softening hard water can do much to reduce deposits. There are certain filters
that can be installed to remove distasteful and corrosive elements. To insure proper water treatment, call a
treatment specialist.

5. Keep your food equipment clean.

Use alkaline, alkaline chlorinated or non-chloride cleaners at recommended strength. Clean frequently to
avoid build-up of hard, stubborn stains. If you boil water in stainless steel equipment, remember the single
most likely cause of damage is chlorides in the water. Heating cleaners that contain chlorides have a similar
effect.

6. Rinse, rinse, rinse.

If chlorinated cleaners are used, rinse and wipe equipment and supplies dry immediately. The sooner
you wipe off standing water, especially when it contains cleaning agents, the better. After wiping
equipment down, allow it to air dry; oxygen helps maintain the stainless steel’s passivity film.

7. Never use hydrochloric acid (muriatic acid) on stainless steel.

Review

 Stainless steels rust when passivity (film-shield) breaks down as a result of scrapes, scratches,

deposits and chlorides.

 Stainless steel rust starts with pits and cracks.
 Use the proper tools. Do not use steel pads, wire brushes or scrapers to clean stainless steel.
 Use non-chlorinated cleaners at recommended concentrations. Use only chloride-free cleaners.
 Soften your water. Use filters and softeners whenever possible.
 Wipe off cleaning agents and standing water as soon as possible. Prolonged contact eventually causes

problems.
