Water Shut Off Valves: There are two water shut-off valves on both the hot and cold water* lines, so that the components in both hot and cold water lines can be isolated for easy removal.

Pressure Reducing Valves: These valves are located in the hot and cold water* lines to reduce the operating pressure to 25 PSI (172 kPa).

Solenoid Valves: There is a solenoid valve in both the hot and cold water* lines to automatically control the water flow.

Detergent Pump: This pump is used to inject a controlled amount of detergent into the hot water line when in wash mode.

Timer Relay: This relay energizes both the hot water solenoid and the detergent pump for the wash cycle; it determines the length of the wash cycle.

Fuse Block & Terminal Strip: To provide a 5 amp fuse to protect the electrical components in the control panel.

Selector Switch:

a) To activate the exhaust fan and cold water* spray. for the Cyclo Maze

ventilation, turn switch to the ‘RUN’ position.

V E N T I L A T O R C O M P O N E N T

F U N C T I O N S

Adjustable Baffle and Removable Access Door: To allow CFM varia-

tions over the length of the ventilator. They are also removable to provide access to the chamber.

Water Spray Nozzles: There are both hot and cold water* spray nozzles.

Fire Damper: To prevent fire from going up the duct; the damper is held open by one 286°F (141°C) fusible link.

Volume Control Damper: A n a d j u s t a bl e, hori zontal bl a d e - t y p e damper is provided at the exhaust collar allowing for velocity changes in the field (after hood installations).

b) To activate the hot water wash cycle for the Cyclo Maze ventilator, turn

switch to the “WASH‘ position.

Cold Water Pressure Gauge: This gauge is used to check the cold water* pressure on the outlet side of the pressure reducing valve. Should read 25 PSI (138 kPa) while in operation.

Plug-Hot Water Line: This plug can be removed and a pressure gauge or thermometer screwed into the hole for field temperature and pressure reading.

Cold Water* and Hot Water Strainers: The strainers located in the PRV valve are used to strain out dirt from the water flow and to protect the solenoid valves and water nozzles from plugging up.

Detergent Pump CheckValves: This valve stops the detergent in the pump and tube from draining back down into the detergent tank when the pump is not in operation, eliminating the need to continually prime the pump.

*H4-25 models are not provided with the cold water feature.

During the day grease accumulates in the interior chamber of the extractor unit in the water wash hood, therefore, a cleaning cycle is provided to properly clean all interior surfaces.

When the selector switch is turned to the ‘WASH’ position at the control panel, the exhaust fan and cold water solenoid* are de-energized.After a 60 second delay (to allow the exhaust fan wheel to stop rotating), a pre-set wash timer energizes the hot water solenoid and detergent pump system for a short cleaning cycle. The hot water and detergent mixture is sprayed through a series of s t rategically placed nozzles to scour the interior of the unit.

CAUTION: If the cleaning cycle is not maintained, accumulated grease can constitute a fire hazard and impair the overall performance of the unit(s) and nozzles.

Hot and cold* water supply to the panel requires a minimum pressure of 40 PSI (276 kPa). Hot water requires a minimum temperature of 140°F (60°C). The pressure reducing valves are factory set for an outlet pressure of 25 PSI (172 kPa).The resulting pressure at the hood nozzle should be 20 PSI (138 kPa).If necessary, adjust the factory preset pressure reducing valve until the required pressure is obtained.

W A S H C Y C L E

Turn selector switch to the ‘WASH’position which will initiate the wash cycle and shut down fan and cold water spray. Check ventilator to see if hot water nozzles are functioning properly. After wash cycle has been completed, remove access door(s) and visually check to see if upper wash nozzles have a uniform spray pattern by observing water droplets on surface of upper chamber.

Remove and clean nozzle orifice if not spraying properly. Remove strainer enclosure on the pressure reducing valve in hot water line.Inspect and clean if necessary.

W A S H T I M E R

N OT E : After control panel and ventilator units have been installed, all hot and cold water* and drain connections made and electric connections completed and system has received factory authorized startup, the system is ready to be put into operation.Refer to start-up check list.

R U N C Y C L E

Tu rn selector switch to the ‘ RU N ’ position, exhaust fan will start and cold water solenoid* will open. Check ventilators to see if cold water spray is functioning properl y. Place hand through slot opening in front of ventilator. There should be an even flat, overlapping spray across the entire length of the ventilator.If nozzles are not spraying properly, remove and clean the ori f i c e. R e m ove access door in order to reach cold water n o z z l e. (See drawing 3). R e m ove strainer (enclosed on the pressure reducing va l ve in cold water line. Inspect and clean, if necessary.

*H4-25 models are not provided with the cold water feature.

A wash cycle of two minutes is preset at the factory. Under extreme conditions such as charcoal broiling or if hot water supply is located some distance from ventilators, it may be necessary to increase time cycle. It is suggested that this be done in one minute increments until proper time cycle is established.

OPERATION: To prime and operate the pump for the first time, it is recommended to use water instead of chemical in case of leaks at tube joints.

1. Place water in container, one inch above the foot valve.

2.Turn on electricity and start pump motor.

3. If liquid does not rise in suction tubing after a minute of operation, loosen discharge tubing from top of pump head.

4.When liquid reaches top of pump reattach tubing.

5. Should pump still not prime, remove suction tube from bottom of pump head and fill it with water. Then attach back to bottom fitting and raise tubing higher than pump. Check all fitting connections for tightness. Excessive tightening may crack head block.

PUMP ADJUSTMENT — Pump adjustment is made by aligning the numbers on the dial with the set point.Loosen the wing nut and rotate dial to set point, then tighten wing nut.

Drawing 5

PUMP ADJUSTMENT CONTROL

1. Electrical Connection: USE CARE, ensure the power supply corresponds to that of the pump. If you connect a 115 volt to a 230 or 240 volt line it will burn out the winding. A 230 volt winding will not operate on low voltage. Do not be a l a rmed if the motor seems to become excessively hot as shaded pole motors operate at 50 degree temperature rise.

2. NOTE: Keep tubing and connections away from heaters as it becomes soft at high temperatures.

3. CAUTION: Hand tighten the tube nuts.Do not use a wrench or pliers to tighten the tube nuts or adapters in the head block. This may cause the head block to crack and would void the warranty.

4. After your pump is in operation, a reasonable amount of care must be taken to keep it clean. Do not spill chemicals on ex t e rior of pump. C h l o rine hy p o c h l o rite leave deposits in the pump, pump lines and valves. In a separate container, mix a weak solution of muriatic acid (1/2 pint to a gallon of water), run this through the pump to clean out d e p o s i t . C h e ck antisyphon va l ve occasionally to make sure this is clean of deposits.Pumping materi a l s that are completely, or very nearly, soluble require little or no flushing.

5. Once every 6 months, open the oil plug at top left of motor cover and apply 4 drops of high temperature oil.

NOTE:Refer to Drawing 6 for pump assembly and part numbers.
