MISTING KIT OVERVIEW
The Misting Kit includes all parts necessary to convert a standard Pro-Watch dispenser to a Misting System. Use of
this kit is only recommended for Pro-Watch systems that have a transformer (internal or external) and is not intended
for use with battery-operated versions.
The kit comes with a spray nozzle, a roll of 3/8" OD poly tubing, a 3/8" ID pickup tube, 2-lobe roller block assembly,
T-50-T squeeze tube, hose clamps, and a footvalve. The larger poly tubing helps to improve the flow so the system
can effectively generate the pressure required to spray chemical through the nozzle.
MISTING KIT INSTALLATION
(1) If applicable, pull the pickup tube out of the chemical container and run the lines dry using the PRIME button.
(2) Shut off power to the dispenser.
(3) Remove the 2 outer screws and the faceplate from the pumphead.
(4) Remove the existing squeeze tube along with the 1/4" poly tubing and 1/4" pickup tube. You can discard these
parts as they will no longer be used.
(5) Remove the existing roller block assembly from the pumphead and install the 2-lobe roller provided in the kit.
(6) Install the T-50-T squeeze tube included with the kit. Pinch the tube with your fingers to help press it into place
between the rollers and pump body.
(7) Apply a light coating of Knight Tube Lube (or equivalent silicone-based lubricant) to the T-50-T squeeze tube.
Avoid getting lube near the pinch points where the bottom of the faceplate grips the tube.
(8) Put the faceplate and screws back on the pumphead. Be careful when tightening the screws to avoid cracking
the faceplate.
(9) Mount the spray nozzle assembly (horizontal or vertical) in the desired location. Do not remove the green
protective cap from the nozzle while mounting — it prevents damage to the spray tip from tools or handling.
(10) Install the provided 3/8" poly tubing between the pickup tube and the input (left) side of the pump's squeeze
tube. Use a hose clamp to secure poly tubing to the squeeze tube. Be sure to draw poly tubing through the end
of the pickup tube.
(11) Insert the footvalve (strainer) into the bottom of the poly tube.
(12) Install the provided 3/8" poly tubing between the output (right) side of the pump's squeeze tube and the elbow
fitting on the spray nozzle assembly. Push the poly tubing into the elbow fitting to secure it. Use a hose clamp to
secure poly tubing to the squeeze tube.
(13) Remove the green protective cap mentioned in step 9, then turn the power back on.
(14) To prime the pump, insert the pickup tube into the chemical container and press the "PRIME 1" button on the
front cover of the system. The pump will run as long as the button is pressed.
PROPER SPRAY NOZZLE PERFORMANCE
•
The tip projects a fixed spray pattern and does not require any adjustments.
•
Because the spray nozzle requires suitable pressure to work properly, it is very important to ensure that there are
no air leaks in the chemical line between the pump and the spray nozzle. Air leaks can hinder the line pressure
which may result in the chemical "dripping" from the nozzle rather than spraying.
