II. INSTALLATION:
A. Mounting and Water Supply.
Mount the unit on a vertical surface using the 4 screws provided through the mounting holes in the cover. The water inlet is
equipped with a female garden hose fitting. The fitting may be removed to permit direct connection to 1/2" NPT pipe.
Water supply pressure should not exceed 125 PSI. Water temperature must not exceed 160 degrees Fahrenheit.
B. Outlet Connection.
Connect the discharge hoses to the outlet garden hose fitting. Spray guns, spray nozzles or foaming wands may be used on
the hose outlets, note that the Select-O-Spray is designed to operate with nozzle flow rates not less than 4 GPM total at 40
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 5, under Optional Accessories for various styles.
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 Select-O-Spray. (Greater lifts will
reduce injection capabilities). The top of the container should not be above the Select-O-Spray. 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.
III. FEED RATE ADJUSTMENT:
Model 606T:
The chemical feed rate is controlled by a metering tip screwed into the metering barb on the side of the unit. The feedrates can be
changed by using a different size metering tip, which is available through Dema (See parts list on page 5). To select a proper size
metering tip for the desired dilution ratio refer to Table 2.
IV. OPERATION:
A. Select-O-Spray 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.
This product is designed only to be used as described in this instruction sheet. Adhere to all warnings and
cautions identified in this document.
WARNING: Installations must conform to all local and national plumbing codes and use
approved backflow prevention and pressure relief devices where required.
ALWAYS DISCONNECT DISPENSER FROM WATER SOURCE WHEN DISPENSER
IS NOT IN USE.
Always read SDS for all chemicals used and follow personal protective guidelines.

V. 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)
3. Is the gun or nozzle(s) sized properly? (Refer to Section II B). Remove gun and/or nozzle(s) and turn on water. If the
injector inducts chemical, the gun and nozzle(s) are improperly sized.
4. Is the metering tip blocked? Remove tip and clear blockage.
5. Is the hose kinked or otherwise obstructed?
6. Is the spray gun fully open?
B. If unit stops drawing chemical.
1. Is the foot strainer clogged? Lift from drum and clean.
2. Are the spray nozzle(s) partially clogged? Remove and clean.
3. Is the metering tip blocked? Remove and clean.
4. Is the injector check valve clogged? Unscrew the four cover screws to take the Select-O-Spray 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.
