DEMA SPRAY STATION II ASSEMBLY MODEL 606T-2 INSTALLATION INSTRUCTIONS

Transcription

1 MODEL 0T-2 The 0T-2 Spray Station II Dispensers are used in any application where a chemical product must be sprayed or foamed without the use of compressed air or a high pressure pump. City water pressure and optional spray gun and foam wand attachments create the correct amount of pressure and foam for cleaning in food service applications such as supermarket meat rooms, deli areas and seafood departments. The 0T-2 is a two chemical product system that include an additional station for clear water rinsing. PVC manifold for hard water resistance Polypropylene injector for chemical resistance Polypropylene cover offers neat appearance Stainless steel back plate offers secure mounting and durability Large ball valve knobs for easy on/off action 1. PARTS CHECKLIST: ITEM DESCRIPTION QTY. A. Spray Station II Assembly 1 B. ¼ ID Tubing & Foot Strainer 2 C. Ceramic Weight 2 D. Metering Tip Kit 1 E. #10 Screw & Anchor Kit Set (Total: Screws & Anchors) 1 F. Label Card 1 2. INSTALLATION: Note: All installations must conform to local plumbing codes and use the approved backflow preventers. WARNING: Water supply should not exceed 12 psi and water temperature must not exceed 10 F. A. Mounting and Water Supply: Locate mounting holes on permanent vertical wall. Drill all holes into the drywall using a ¼ diameter bit for use with the included #10 screw and anchor set. (If mounting unit to wood and you do not plan to use the included anchors, drill 1/ holes.) Insert anchors into drilled holes and hammer them into the wall until they are flush with face of wall. Assemble the #10 screws with a phillip screwdriver into the anchors for the keyhole slots so the screw heads are sticking out of the wall approximately ½. Mount the unit by inserting the screw heads through the keyhole slots and tightening the screws. Secure the unit by inserting screws into the lower 2 holes and tightening the screws. The water inlet is equipped with a female garden hose fitting. The fitting may be removed to permit direct connection to / NPT pipe. B. Outlet Connection: Connect the discharge hose to the outlet garden hose fitting. NOTE: Be sure to clamp garden hose onto wall approximately 1 ft below the unit. (Clamp, Screws, & Anchors are supplied.) Spray guns, spray nozzles or foaming wands may be used on the hose outlet, note that the Spray Station II is designed to operate with nozzle flow rates not less than GPM total at 0 PSI. When a spray gun or nozzle is used, hose lengths must not exceed those shown in Table 1. Hoses, spray guns and foam wands are available through Dema. See the parts list on page under Optional Accessories for various styles. TABLE 1 Hose I.D. /" 1/2" /" Max. Length 1 ft. 0 ft. 100 ft. C. Chemical Supply: WARNING: USE CARE WHEN HANDLING HAZARDOUS CHEMICALS. Place the chemical container in a convenient location not more than six feet below the Spray Station II. (Greater lifts will reduce injection capabilities). The top of the container should not be above the Spray Station II. Cut the vinyl tubes to any convenient length that will allow the tubing to reach the bottom of the container. Drop the tubing ends with the strainers into the chemical containers. Push the other tubing ends over the chemical inlet barbs located on the sides of the unit. I-0 Pg. 1 of

2 MODEL 0T-2. FEED RATE ADJUSTMENT: The chemical feed rate is controlled by metering tips screwed into the hose barbs of the injectors on each side of the unit. The feed rates can be changed by using different sized metering tips. To select the proper sized metering tip for the desired dilution ratio, refer to Table 2. TABLE 2 METERING TIP SELECTION CHART FLUID DILUTION RATIOS WITH METERING TIP KIT (100-1K) Injection Rate for Viscosities Shown Metering Tip Color 1 cps cps 200 cps Oz/Gal Ratio Oz/Gal Ratio Oz/Gal Ratio Tan Orange Turquoise Pink Clear Brown Red White Green Blue Yellow Black Purple Gray No Tip All injection ratios are based on 0 PSI inlet water pressure and a water flow rate of 2. GPM. Note: Leaner dilutions are available using DEMA metering tip kit #100-1KU or capillary tip #-1P. OPERATION: The Spray Station II permits the operator to select one of two chemicals or clear water rinse by opening and closing the appropriate valve. Only one valve should be opened at any time. If two valves are opened simultaneously, the injector will not induct chemical. When using a spray gun or foaming wand make sure that the gun on the end of the hose is in the full open position when inducting chemical.. SERVICING: CAUTION: TURN OFF WATER SUPPLY BEFORE SERVICING. A. If unit fails to draw chemical: 1. Is more than one valve open? 2. Is the hose too long? (See Table 1). Is the gun or nozzle(s) sized properly? (Refer to Section 2 B). Remove gun and/or nozzle(s) and turn on water. If the injector inducts chemical, the gun and nozzle(s) are improperly sized.. Is the metering tip blocked? Remove tip and clear blockage.. Is the hose kinked or otherwise obstructed?. Is the spray gun fully open? I-0 Pg. 2 of

3 B. If unit stops drawing chemical: DEMA SPRAY STATION II ASSEMBLY MODEL 0T-2 1. Is the foot strainer clogged? Lift from drum and clean. 2. Are the spray nozzle(s) partially clogged? Remove and clean.. Is the metering tip blocked? Remove and clean.. Is the injector check valve clogged? Unscrew the four cover screws to take the Spray Station II unit off the wall. Remove the three ball valve handles to separate the cover from the manifold. Remove the square, plastic metering knobs to inspect the check valve ball, spring and O-ring. CAUTION: WHEN SERVICING UNIT BE SURE THAT REPLACEMENT PARTS HAVE BEEN INSTALLED ACCORDING TO DRAWING. BE CERTAIN CHECK VALVE PARTS ARE IN PLACE.
