Frequently Asked Questions - WVU96 Wells

Can the Wells WVU96 hood be used with gas cooking appliances?

No, this ventilator is designed exclusively for electric cooking appliances. Using it with gas units poses a suffocation hazard as it does not remove combustion products.

How often should the baffle filters be cleaned?

Baffle filters should be cleaned at least weekly. They are reusable and can be washed in a sink or dishwasher with mild detergent.

What does the 'Check Filters' light indicate?

The 'Check Filters' light means one or more filters (baffle, pre-filter, or filter pack) are not properly installed. Ensure all filters are correctly seated.

What does the 'Replace Filter' light mean?

This light indicates the filter pack is nearing the end of its service life. Replace it promptly to avoid a clogged filter shutdown.

Can the filter pack be cleaned and reused?

No, the HEPA/carbon filter pack is disposable and cannot be cleaned. Washing will ruin it. Only genuine Wells replacement parts should be used.

How do I reset the hood after a 'Service Required' shutdown?

Turn the VENTILATOR POWER SWITCH to OFF, then back to ON. If the condition persists, contact an authorized Wells service agent.

What maintenance is required for the fire suppression system?

The Ansul® system must be inspected every 6 months by an authorized Ansul distributor. The agent tank requires hydrostatic testing and agent replacement every 12 years.

Can I install a remote pull station for the fire suppression?

Yes, a remote manual pull station can be installed by an authorized Ansul distributor if required by local codes or accessibility needs.

What is the recommended fresh air exchange rate for the installation site?

A minimum of 1600 CFM fresh air into the area is recommended to ensure adequate dilution of cooking odors.

How do I change the exhaust discharge from horizontal to vertical?

Remove the front discharge vent panel and damper, then install the top discharge scoop assembly and damper. Detailed steps are in the manual under 'Discharge Direction Change'.

INSTALLATION continued

DANGER FIRE HAZARD

Fire suppression system must be charged and certified by an authorized Ansul® distributor.

DO NOT attempt to modify or bypass the fire suppression system.

An uncontrolled fire can cause serious injury or death.

NOTE:

If the fire suppression system is discharged, a buzzer will sound continuously. The unit will remain inoperable until the fire suppression system is serviced, recharged and reset by an authorized Ansul® distributor.

Charging of the Ansul® Fire Suppression system must be in accordance with Ansul® Design, Installation, Recharge and Maintenance Manual, #418087.

NOTE:

If a REMOTE MANUAL PULL STATION is installed, moving the ventilator for any reason may cause the Ansul® system to discharge.

IMPORTANT:

Should the fire suppression system discharge: all nozzles must be replaced, and all lines thoroughly cleaned, prior to recharging the system.

Residual fire suppression media may compromise the flow and dispersion of fire suppression media in any subsequent activation.

The alarm relay is activated by the Ansul® fire detection system. If the installation includes a building alarm system, connect to terminals T7 & T8 of the terminal block in supply connection box. These terminals are configured from the factory for normally open operation.

The ventilator will operate properly, and the appliance control relay will be energized, only when:

1. The VENTILATOR POWER SWITCH is "ON".
2. The Ansul® Fire Suppression System is charged and armed.
3. All filters are in position and serviceable, and the ventilator air flow system is satisfied.

FIRE SUPPRESSION SYSTEM INSTALLATION

EACH 4' FOOT SECTION OF THE FIRE SUPPRESSION SYSTEM is comprised of two containers of Ansulex® Low pH liquid fire suppression media and a system pressurization canister, plus associated plumbing. Actuation controls are contained in the Automan enclosure.

The hood is supplied with a field installed MANUAL PULL STATION, which must be set-up at the time of installation by an authorized Ansul® distributor.

The MANUAL PULL STATION allows for for manual emergency shutdown of cooking appliance power, and actuation of the fire suppression system.

Six (WVU48) or twelve (WVU96) NOZZLES disperse the fire suppression media. Two inner nozzles protect the fan and plenum. The appliance nozzles are swivel mounted, and must be directed toward the cooking surface of the installed cooking appliance.

If the ventilator is situated such that the supplied manual pull station cannot be installed or is not readily accessible, a REMOTE MANUAL PULL STATION may be required by local codes. Any such remote manual pull station must be installed by an authorized Ansul® distributor in accordance with the AUTHORITY HAVING JURISDICTION.

The fire detection system utilizes six (WVU48) or twelve (WVU96) electronic thermal detectors with an actuation set point of 225^ F ( 107^ C) in the upper hood locations and 275^ F ( 135^ C) detectors in the lower wall locations. The signaling from any of these detection devices will automatically discharge the fire suppression media through all nozzles, disable the cooking appliances and cause the alarm to sound.

Fire suppression media will form an emulsion designed to both smother and cool the fuels in/on the cooking appliance.

INSTALLATION

FIRE SUPPRESSION SYSTEM INSTALLATION (continued)

The MANUAL PULL STATION and any similar REMOTE MANUAL PULL STATION will activate the fire suppression system when the ring on the pull station is pulled to its full extent.

DANGER BURN HAZARD

Any additional remote pull station must NOT be installed on the front of the cooking appliances,

Discharge of the fire extinguishing system into hot grease or oil may cause hot foam to spill over from the cooking surface or frypot.

Serious burns and other injuries can result from contact with hot oil and from slipping in spilled oil.

The manual pull station is installed on the right side (facing the unit. It may, however, be relocated to the left side of the ventilator hood by an authorized Ansul® agent.

INSTALLATION

NOTE:

The BAFFLE FILTERS, PRE-FILTERS and FILTER PACK actuate position switches when they are properly positioned. They must be properly installed for the under hood cooking appliance contactor to be energized.

WARNING SLIP AND FALL HAZARD

DO NOT operate any grease-producing cooking appliance

(e.g. fryer or griddle) unless the grease cup is properly installed. Oil will drip onto floor creating a slipping hazard.

CAUTION BURN HAZARD

DO NOT operate any cooking appliance unless the grease cup is installed.

Moisture dripping onto hot surfaces, oil or grease can cause splattering.

FILTER INSTALLATION

Note air flow direction arrow on filter pack. Remove old filter pack and slide new filter pack fully into the appropriate slot. Verify that the airflow arrow points toward the fan.

Baffle filters are reusable and should be cleaned at least weekly. Change pre-filters and smoke/odor filter pack as indicated on the front panel. These filters are disposable and cannot be reused. The smoke / odor filter pack is accessed thru the front service door.

Pre-filters are located behind the baffle filters, when installing pre-filters engage top retaining flange prior to seating pre-filter housing in lower chamber.

Use only genuine Wells replacement parts and filters, call [phone] or your authorized Wells service agent. Parts supplied by others will void your warranty and may not provide safe operation.

BAFFLE FILTER and GREASE CUP INSTALLATION

1. Install baffle filter from front. Engage the baffle filter in the retainer slot. Push up until the baffle filter bottom clears the lower lip of the retainer, then lower the baffle filter into the bottom retainer
2. Install GREASE CUP into brackets below the baffle filter.

Note: Failure to install the GREASE CUP will allow grease and moisture from the BAFFLE FILTER to drop into hot cooking surfaces, creating both a SAFETY HAZARD (hot oil splatter) and a HEALTH HAZARD (contamination of the cooking surface or cooking oil).

OPERATION

Control Panel

NOTE: Cooking appliances must be operated in accordance with the manufacturer's instructions.

During normal operation, the illuminated power switch will be the only light on the control panel that will be ON.

If the CHECK FILTERS light illuminates, check BAFFLE FILTERS, PREFILTERS, and the HEPA AIR FILTERS for proper installation.

If the REPLACE PRE-FILTERS light illuminates .. Replace the Pre-filters.

If the REPLACE FILTER light illuminates, replace the FILTER PACK.

NOTE: the REPLACE FILTERS light is a warning that filter pack is nearing the end of its service life. The ventilator will continue to operate for a period of time after the REPLACE FILTER LIGHT turns ON to allow continued operation through a peak period. However, filter pack must be replaced within a short time period or it will clog, disabling the ventilator and appliances.

If the SERVICE REQUIRED light illuminates, the filter pack is restricted to the point of insufficient airflow for proper operation and the Ventilator will shut down until the underlying clogged filter situation has been corrected. Replace clogged item with a fresh filter to correct the condition. Reset the unit by turning VENTILATOR POWER SWITCH to OFF, then back to ON.

If the air curtain service required lights illuminate, there is insufficient airflow for proper operation. Call an authorized Wells Service Agent.

A failure of incoming electric power will cause a shut down of the unit. Reset the unit by turning VENTILATOR POWER SWITCH to OFF, then back to ON.

Operation Lights

There are three (WVU48) equipment lights and six on the (WVU96) that provide illumination of the working area. These lights are controlled by the main power switch.
