Installation

Mount the unit no higher than 6 feet from the chemical container. Take into account the proximity to the chemical,
drain, and power for the unit. Use the included screw and anchor kit to secure the mounting bracket to the wall and
then mount the unit on the wall. Then cut the tubing to the proper length to reach from the chemical container to the
unit and the unit to the drain where the chemical is being dispensed.

Squeeze Tube Installation

Install the squeeze tube by
removing the pump cover by
depressing the tab on the
front of the unit. (1) Place
one end of the squeeze tube
on the left side of the pump
in the slot provided. (2)
Wrap the squeeze tube
around the rollers of the
pump. (3) Then stretch the
squeeze tube so that the end
of the tube goes into the slot
provided. (4) Replace the

cover on the pump.

Retaining Clip

There is a clip on the bottom of the unit. This is to help relieve strain on
the power cord. Place the power cord through this strain relief to help the
power cord from coming unplugged from the unit.

Clasp Close Pump Heads

The pump heads have an added feature which will
help to ensure the pump head is installed properly.
When pushing the pump head on be sure to see the
clip is fully covering the notch as seen in the first
picture. If the tab is not fully engaged, there is a
possibility of it popping off the pump head as seen in
the second picture.

If the unit loses power, it will not lose the program for 200 hours, but it will not run the pump from the rechargeable
display back up battery and will not dispense chemical. If the unit becomes unplugged from the wall for a short
amount of time, plugging the unit back in will not affect the programming done to the unit.
