PAX Water Mixer (PWM100)
Installation/Operation Manual
8
1. Bring power (120 VAC, 60 Hz, GFCI-protected, 20 amp circuit) onsite to tank.
2. Install a safety disconnect switch and connect power.
NOTE:
Make sure that the safety disconnect switch is in the off position; follow proper lockout/
tagout procedures.
3. Penetrate the side of the tank hatch (1.025” or 26 mm hole).
4. Run conduit (3/4” or 20mm) from the safety disconnect switch to a junction box at the tank
hatch, and then from the junction box to the penetration of the hatch lip. Pull wire from safety
disconnect switch to the junction box (copper wires min. 12 AWG (3.31 mm
2
), type THHN,
rated 90 °C).
5. Bring the PAX Water Mixer to the roof of the tank.
NOTE:
Keep PAX Water Mixer inside its packaging for protection. The holes on the sides of the
packaging can be used to secure a rope.
6. Remove mixer from its packaging and tie off the power cord (halfway between mixer and end
of cord) to ensure that mixer cannot fall off the top of the tank. Then thread the end of the
power cord through a strain relief, the tank penetration and the conduit that connects to the
junction box.
7. Hold the mixer over the open hatch by gripping its power cord and slowly lower into the water.
a) Continue to lower the mixer, a few feet at a time, until it makes contact with the floor of
the tank.
b) After the mixer makes contact with the floor of the tank, allow 3-4 feet (1-1.5 m) of slack in
the cable.
c) If there is excess power cord, coil it up and secure it to the ladder above the water.
NOTE:
The PAX Water Mixer is designed to come to rest on the floor of the tank and point upwards.
On a sloped floor, the mixer will come to rest at a low point on the tank floor.
7. PAX Water Mixer Start-Up and Shut-Down Procedure
NOTE:
After the initial installation or any tank maintenance, always perform the PAX electrical
checks before placing the PAX Water Mixer in service.
Checks include:
• Measuring Motor Resistance and Ground
• Measuring AC Current
• Measuring AC Voltage
1. To turn the PAX Water Mixer ON, energize the GFCI breaker and turn ON the safety disconnect
switch.
2. To turn the PAX Water Mixer OFF, turn off the safety disconnect switch and de-energize the
GFCI breaker.
