Sequence of Operation

A. Manual Inputs

Manual Inputs refer to the operator interface on the front of the control panel. The five lower buttons are used for manual operation of the fans, and to initiate the wash cycle(s). The five upper buttons are used to program the PAWS control panel for automatic operation. See Figure III and III.A.

1. Fan Off/Wash Off button

This button Cancels either fan or wash operation. A Fire Condition initiated by the hood Fire System, optional Fire Pull Switch, or the exhaust damper switch will override this input. This button will

Figure III.A

Page 13

also cancel the Fire Delay Cycle that occurs after a Fire Condition has cleared.

2. Fan On/Wash Off button

This button turns the fans cancels the wash operation. A Fire Condition will override this input.

3. Fan Off/Wash On button

This button cancels the fan operation and initiates the hood wash cycle. The PAWS panel will wash the hood for an adjustable period of time (2-10 minutes) and automatically shut off. This button is typically used at the end of the day to shut off the fans and clean the hood.

PAWS models P30* through P33* have a single wash output. This single output will control up to a 1-1/2” solenoid valve that will provide sufficient water flow for up to 50 linear feet of hood. PAWS models P34* through P47* have multiple wash sequences that range from 2 to 8 outputs, depending on the model. When a wash cycle is initiated the outputs operate sequentially, one after the next. The total time required to complete all wash sequences is equal to the length of the wash (adjustable 2-10 minutes) times the number of wash outputs. For example if you have a 4output PAWS panel and have adjusted the wash duration for Wash cycle will operate for 16 minutes (4 minutes for each output).

4. Fuel Reset button (optional feature)

This button will restore power to the gas solenoids that control the flow of gas to the cooking equipment, served by the hood that is controlled by the panel.

The electrical power to the cooking equipment may also be restored after pressing the fuel reset button. A main service breaker that is equipped with a shut off device controls the electrical power.

The fuel-reset feature is provided to integrate the PAWS panel with the Hood Fire Suppression system to shut off fuel to the cooking equipment during a kitchen fire. There are two types of fuel reset, one with battery back-up and one without.

5. Alarm Silence button

This button will silence the horn that sounds intermittently when the PAWS panel is in a TROUBLE mode.

A TROUBLE mode may be initiated by a LOW DETEGENT condition, PAWS Water Supply Valve Closed (optional), or, PAWS Water Pressure Low condition (optional).

If additional trouble conditions occur after the horn silence button is used; the horn will not re-sound until all trouble conditions are cleared and another trouble condition is initiated.

B. Programmed Events

The PAWS panel can automatically control the Fan and Wash operation by a user defined operation schedule. This feature may or may not be used. It is not required for the panel to function. There are three programmable functions:

 FAN ON {FAN ON #1 & #2}  FAN OFF {FAN OFF #1 & #2}

 WASH ON {WASH ON #1 & #2}

Each of the three functions may be set to occur twice on a given day (example FAN ON #1 and FAN ON #2).

Whether a function is initiated manually or by a programmed event, the last event to occur takes precedence, with exception to Fire Conditions. Fire Conditions always take precedence

1. Fan Off Event

{Fan Off #1 & #2}

This event cancels fan operation. The Fan Off function is programmed when the user wishes to cancel fan operation without initiating a wash, typically used for daytime fan shut down.

A Fire Condition initiated by the hood Fire System, optional Fire Pull Switch,

120

Page 14

or the exhaust damper switch will override this input.

Power to the Electric Shunt trip Output is turned “ON”.

2. Fan On Event

{Fan On #1 & #2}

This event turns the fans “ON”. A Fire Condition will override this input.

3. Wash On Event

{Wash On #1 & #2}

This event cancels the fan operation and initiates the hood wash cycle.

The Wash On function is programmed when the user wishes to cancel fan operation and initiate the hood wash cycle. It is best to wash the hood immediately after the cooking equipment is shut down, the grease in the hood is still warm and more easily cleaned. If the hood is washed after cool down, an extended wash period may be required. Typically the user will program this event as the last function of the work day, since the fans are shut down and one wash cycle per day is usually adequate.

The user may elect to program this function to occur in the middle of the night when hot water demand is low. The fan does not have to be on in order to program this event.

Please refer to the Programming section of this manual to ensure the Wash event does not conflict with other programmed events.

C. Device Inputs

There are peripheral devices that are connected to the PAWS panel for purposes of monitoring operation and causing variances in panel operation due to external events. The following is a list of devices and their effect on panel operation.

1. Hood Mounted Exhaust Damper Duct Switch (optional hood feature)

Closure of the duct switch indicates that the exhaust damper on the connected hood has closed.

Both exhaust and supply fans are turned “OFF”. The wash spray in the exhaust plenum is turned interior of the hood and prevent flame spread.

“ON” to cool the

In order to return the panel to Normal operation the Duct Switch must be open.

When the Duct Switch opens a Fire Delay Cycle will maintain the plenum wash spray and fan off condition for a period of Delay may be cancelled by pushing the Fan Off/ Wash Off button.

A Duct Fire Condition takes precedence over all other events.

A pulsed tone will emanate from the Alarm Horn while the fire condition is active.

Following Actions apply to MODELS P31*, P32*, P35*, P36*, P45* and P46* ONLY.

Power to the Gas Solenoid output is turned “Off “

After the Duct Fire Condition and Fire Delay Cycle are cleared: press the Fuel Reset button to reset the Gas Solenoid and Electric Shunt trip outputs.

After the fire condition is cleared the horn sounds a constant tone until the Fuel Reset Button is activated.

2. Hood Fire Suppression System Switch (N.C.) (optional connection)

Normally Closed dry contacts on the Hood Fire Suppression System (Ansul R-102, for example) are connected to the PAWS panel. Upon discharge of the Fire Suppression system:

The exhaust fan is turned “ON” and the supply fan is turned “OFF”. The wash spray in the exhaust plenum is turned “ON” to cool the interior of the hood and prevent flame spread.

Power to the Electric Shunt trip Output is turned “ON”.

In order to return the panel to Normal operation the Fire Suppression System must be reset.

When the Fire Suppression System is reset a Fire Delay Cycle will maintain the plenum wash spray and fan condition for a period of 5 minutes. The

5 minutes. The Fire Cycle

Fire Cycle Delay may be cancelled by pushing the Fan Off/ Wash Off button.

A Fire System Condition takes precedence over all events other than a Duct Switch Event.

Following Actions apply to MODELS P31*, P32*, P35*, P36*, P45* and P46* ONLY

Power to the Gas Solenoid output is turned “Off “.

A pulsed tone will sound from the Alarm Horn while the fire condition is active.

The following actions apply to MODELS P31*, P32*, P35*, P36*, P45* and P46* ONLY

Power to the Gas Solenoid output is turned “Off “.

After the Fire System Condition and Fire Delay Cycle are cleared, pressing the Fuel Reset button will reset the Gas Solenoid and Electric Shunt trip outputs.

After the fire condition is cleared a constant tone is delivered until the Fuel Reset Button is activated.

3. Fire Pull Switch (N.C.) (Panel option)

The optional Fire Pull switch may be mounted on the PAWS panel or in a remote location, such as at the point of egress. When the Fire Pull Switch is activated:

The exhaust fan is turned “ON” and the supply fan is turned “OFF”. The wash spray in the exhaust plenum is turned “ON” to cool the interior of the hood and prevent flame spread.

Power to the Electric Shunt trip Output is turned “ON”.

In order to return the panel to Normal operation the Fire Pull Switch must be reset.

When the Fire Pull Switch is reset a Fire Delay Cycle will maintain the plenum wash spray and fan condition for a period of 5 minutes. The Fire Cycle Delay may be cancelled by pushing the Fan Off/ Wash Off button.

A Fire Pull Switch Condition is equal to a Fire System Condition and takes precedence over all events other than a Duct Switch Event.

A pulsed tone will emanate from the Alarm Horn while the fire condition is active.

After the Fire Pull Switch condition and Fire Delay Cycle are cleared, the Gas Solenoid and Electric Shunt trip outputs can be reset by pushing the Fuel reset button.

After the fire condition is cleared a constant tone is delivered until the Fuel Reset Button is activated.

4. AC Power Loss (N.C.) (Panel option)

Loss of AC power will disable the outputs of the panel with exception of the Gas Solenoid circuit (when provided).

The Fire Pull Switch, Fire System Switch, Duct Switch, or Kill Switch will override the AC power loss condition and cause the actions listed for each input.

Models P32*, P36*, and P46 ONLY!

After a 2-minute delay, power to the Gas Solenoid output is turned “OFF”. When AC Power is restored the “Fuel Reset” button must be pushed to close the circuit to the gas solenoid valve output and open the circuit to the shunt trip output.

5. Detergent Probe (N.C.)

The detergent probe is provided with the PAWS panel detergent tank. When the detergent in the tank is low, the probe initiates a Low Detergent Condition (PAWS Trouble Condition).

The Detergent Pump Output is turned “OFF”.

The Probe is set to disable the pump prior to losing fluid in the pump body. The pump will not need to be primed once the detergent supply is replenished.

The horn will sound intermittently and may be silenced with the Alarm Silence button.

Page 16

6. PAWS Supervised Water Supply Valve (N.O.) (Panel option)

The PAWS panel water supply valve may be equipped with a switch to monitor the status of the valve. If the valve is closed a PAWS Trouble Condition is initiated. The horn will sound intermittently and may be silenced with the Alarm Silence button.

7. PAWS Water Supply Pressure Switch (N.O.) (Panel option)

The PAWS panel may be equipped with a pressure switch to monitor adequate water supply. If the pressure switch is activated due to low water pressure a PAWS Trouble Condition is initiated. The horn will sound intermittently and may be silenced with the Alarm Silence button.

The PAWS panel can automatically control the Fan and Wash operation by a user defined operation schedule.

This feature may or may not be used. It is not required for the panel to function. There are three programmable functions:

1. FAN ON {FAN ON #1 & FAN

2. FAN OFF {FAN OFF #1 & FAN

3. WASH ON {WASH ON #1 &

Each of the three functions may be set to occur twice on a given day (example FAN ON #1 and FAN ON #2).

Please refer to the PAWS Programmed Events Worksheet included in the Appendix of this manual for an outline of the Event Schedule.

Plan the Programmed Event Schedule.

Determine your operation schedule by completing a copy PAWS Programmed Event Schedule Worksheet installation package).

When planning the event schedule you must account for the time required by the wash cycle.

In the previous section Duration” the length of the wash cycle was determined. Do not schedule fan operation until sufficient time has passed for the wash cycle to run to completion.

If your panel includes sequential wash operation determine the wash output quantity.

(

bottom display line will read “PROGRAM WASH QTY. X

the “X” is shown, is the wash quantity value. Multiply the quantity of wash outputs by the

wash duration to determine the total wash time required.

EXAMPLE: If DURATION

output quantity is 4, total wash time is 16 minutes (4 min. wash duration x 4 wash outputs = 16 minutes).

To stop the operation of the fans a “ OFF” event OR a “WASH ON” event may be scheduled. While both functions turn the fans off, the WASH ON function will also run the hood(s) through a wash cycle.

You may schedule any function independent of relative functions. For example, if you normally operate the fans manually, but want to ensure that the fans are shut off each night, you could program a “FAN OFF” event at the end of the day. operations cook past midnight, so you may want to program a “ start of the cooking operation, and schedule a “

A. Detergent Dispensing System (pump)

1. Detergent Tank

The detergent tank should be replenished at least weekly. The Low Detergent Probe will monitor the need for more frequent refills.

After an extended period of time the tank may require cleaning. The probe and pick up tube may be removed, but ensure they are reinstalled as shown in Figure II.C.1.

2. Detergent

AVTEC EVAC is a biodegradable detergent specifically formulated for use with water wash hoods.

AVTEC will provide a Lifetime Warrantee for the PAWS Detergent Dispensing System when AVTEC EVAC is used exclusively.

EVAC can be obtained through Authorized AVTEC Service Agents. Refer to the EVAC spec sheet in the Appendix of this manual.

3. Detergent Pump

Every six months:

Check the Foot Strainer Pick-Up to ensure the screen is not clogged. Refer to Figure II.C.1.

Check all tubing fittings to ensure they are tight.

For additional information refer to the pump manufacturer's manual that is included in the AVTEC Ventilator manual.

B. Plumbing

A Wye (line) strainer is included in the PAWS water manifold to protect the water solenoid(s) and hood spray nozzles. If you experience a loss in water pressure it is frequently due to a clogged wye strainer.

Before opening the cleanout on the wye strainer make sure the water is “OFF” and the water manifold is not under pressure.

A bucket should be placed under the cleanout prior to removing the cleanout plug. Some water spill will occur.

Thoroughly clean the strainer screen and make sure additional debris is not lodged in the wye strainer body. Refer to Figure VI.B.
