Installation
WARNING: INSTALLATION OF DEMA PRODUCTS MUST MEET ALL APPLICABLE
ELECTRICAL CODES AND REGULATIONS ESTABLISHED BY NATIONAL, CITY,
COUNTY, PARISH, PROVINCIAL OR OTHER AGENCIES. IT IS POSSIBLE THAT
ELECTRICAL CODES AND REGULATIONS REQUIRE THAT A CERTIFIED
ELECTRICAL CONTRACTOR OR ENGINEER PERFORM THE ELECTRICAL
INSTALLATION. FOR QUESTIONS, CONTACT A CERTIFIED ELECTRICIAN.
1. Determine a suitable location to mount Trapper. The following should be considered:
a. tubing going to and from the pump
b. chemical location
c. drain pipe injection point
d. Electrical wall outlet when using the plug in AC version.
2. Attach the mounting bracket (included) for the Trapper using appropriate screws and wall anchors.
a. When using the battery operated version, mount the battery enclosure mounting bracket next to the
Trapper mounting bracket. The Trapper and battery mounting brackets can be meshed together to
create a single mounting bracket installation.
3. If using a battery version, install 8 “D” cell heavy duty batteries in the battery holder.
4. Mount the Trapper pump and battery enclosures on the mounting bracket.
5. Install injection fitting (drain application) or spray nozzle (deodorizing application).
a. Drain Application: Install the ¼” compression fitting to the desired drain pipe.
i. Note: Alternative saddle or pipe fittings can be used; Trapper is setup to use ¼” LDPE
tubing.
b. Deodorizing Application: Install the spray nozzle so that it will mist over the desired area to be
treated.
6. Install the ¼” LDPE tubing from the chemical to the pump and from the pump to the drain pipe fitting or spray
nozzle fitting.
a. Note: The Trapper pump is setup with ¼” push on fittings for easy connection.
7. Apply power to the Trapper by plugging the 115/230VAC wall power plug or the battery module to the round
electrical power connector on the bottom of the Trapper.
a. There is a plastic clip near the power connector to retain the power cable to secure the power line
from coming disconnected.
8. Program the Trapper (see programming section in this instruction manual).
9. Prime the pump.
a. Press any button 1 time to wake up the control.
b. With the display on, press and hold the right arrow for 2 seconds to start prime.
