Unit overview
This simple 12 volt 75mg unit is designed to keep your
drinking water system clean from the inside of your water
reservoir. This unit can be programmed to run for 5 or 10
minutes with 3 or 8 hours off in a 24 hour period. The cycle
timing is setup simply by plugging in the EZ-500T. The EZ-500T
mounts to the back of your water cooler or water filter
cooler on the condenser so it will not take up any extra
room.

Installation instructions
- From the back of the water cooler (or where applicable),
using a 21/64 drill bit or a hole punch for soft stainless
steel, make a hole through the reservoir. Note, you
should check for clearance of the reservoir sealing
system and floats before making a hole in the reservoir.
If drilling, always make a small hole first working
your way up to the 21/64 bit for soft stainless steel.
- Attach the supplied stainless steel bulkhead fitting
to the reservoir with the O-ring on the inside of reservoir
and the threads and nut on the outside.
- Remove the baffle assembly in the reservoir. Drill
a 5/16 hole through the baffle assembly (if needed)
or use a 5/16 hole punch. The hole should be near the
outside edge of baffle.
- Cut to size the 5/16 ozone tubing from the bulkhead
fitting to the bottom of the reservoir and then push
the tubing through the baffle.
- Attach the ozone stone to the tubing so that it
sits just off the bottom of the reservoir and replace
the baffle assembly. Now attach the tubing to the bulkhead
fitting.
- Attach the EZ-500T to the upper part of the condenser.
- Cut the tubing to size from the reservoir bulkhead
fitting to EZ-500T bulkhead fitting and attach the tubing
to the EZ-500T.
- Cut the tubing six to 12 inches from the EZ-500T
and install the check valve with the arrow pointing
to the Reservoir and away from the EZ-500T.
- Fill the water cooler and connect the EZ-500T to
the 12V DC power supply.
- Very important - If your reservoir is a sealed type
with a one way check valve, the check valve will need
to be replaced with a non check valve type filter for
venting purposes. This filter can be obtained from the
manufacture of the water cooler.
