PURPOSE:
The RAPID FIRE is a spray system designed with a single knob to control OFF, RINSE and up to two chemicals
using a single chemically resistant plastic injector. There is full water flow whenever the valve is open with the
option of using a 2.1 or a 3.3 injector. A 2.7 gallon per minute injector is standard. RAPID FIRE dispensers can be
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 RAPID FIRE offers the following advantages over a traditional spray system:
●No manifold ●Polypropylene injector for chemical resistance
●No ball valves ●Large knob for easy turning. ●6 GPM Rinse Flow
●Stainless Steel cover with foam wand storage offers neat appearance
NOTE: ALL INSTALLATIONS MUST CONFORM TO LOCAL PLUMBING CODES AND USE THE APPROVED
BACKFLOW PREVENTORS.
WARNING: WATER SUPPLY PRESSURE MUST NOT EXCEED 125 PSI AND WATER TEMPERATURE MUST
NOT EXCEED 150°F (66°C). USE CARE WHEN HANDLING HAZARDOUS CHEMICALS.
CAUTION: TURN OFF WATER SUPPLY BEFORE SERVICING. WHEN SERVICING UNIT BE SURE THAT
REPLACEMENT PARTS HAVE BEEN INSTALLED ACCORDING TO DRAWING.

2. INSTALLATION:
NOTE: ALL INSTALLATIONS MUST CONFORM TO LOCAL PLUMBING CODES
AND USE THE APPROVED BACKFLOW PREVENTORS.
WARNING: WATER SUPPLY PRESSURE MUST NOT EXCEED 125 PSI AND WATER
TEMPERATURE MUST NOT EXCEED 150°F (66°C). USE CARE WHEN
HANDLING HAZARDOUS CHEMICALS.
A. MOUNTING AND WATER SUPPLY:
Mount in a convenient location using the screw and anchor kit provided
The water inlet is equipped with a female garden hose fitting. The fitting may be removed to
permit direct connection to 1/4” NPT pipe.
WARNING: WATER SUPPLY PRESSURE MUST NOT EXCEED 125 PSI AND WATER
TEMPERATURE MUST NOT EXCEED 150°F (66°C).
B. OUTLET CONNECTION:
Connect the discharge hose to the brass outlet garden hose fitting and squeeze the hose clamp
around the hose. Locate the position for the mounting screw, and mount the hose clamp to the
wall using the remaining screw and anchor. Spray guns, spray nozzles or foaming wands may be
used on the hose outlet. We recommend spray nozzles of 6 GPM or higher (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 the last page for the
various styles.

Max. Length 15 ft. 50 ft. 100 ft.
C. CHEMICAL SUPPLY:
WARNING: USE CARE WHEN HANDLING HAZARDOUS CHEMICALS.
Place the chemical container(s) in a convenient location not more than six feet below the RAPID
FIRE (greater distances will reduce injection capabilities). The top of the chemical product
container should never be higher than the RAPID FIRE. Cut vinyl tubes to any convenient length
that will allow the tubes to reach the bottom of the container(s). Remove the screw (22) and
knob (21), raise the hinged cover, and push the other tubing ends over the chemical inlet barbs
located on the sides of the injector. Place the tubing ends with the foot valves into the chemical
containers.

3. CHEMICAL INDUCTION:
The chemical induction is controlled by metering tips screwed into the hose barb(s) located on the
sides of assembly. The feed rates can be changed by using different sizes of metering tips. To select
the proper size of metering tip for the desired dilution ratio, refer to Table 2 below.

Note: Leaner dilutions are available using DEMA metering tip kit #100-15KU or capillary tip
#44-61P
4. OPERATION:
The RAPID FIRE permits the operator to select either chemical or clear water rinse by turning the
selector knob. 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.

side of the assembly to knock loose the check valve. Be careful not to lose the check ball or spring when
removing the check valve body.
4. Replace both inner and outer o-rings on check valve body and reassemble all components from all steps
listed above. Note that smaller diameter end of the spring goes against the ball. See Detail A for assembly
of the driver gear.
