Step 10
Replacing the Housing
After verifying the UV Lamp is working, turn chiller off and
unplug power cord. Lower housing over chiller.
It is important to line up housing with the control panel. If
the control panel does not fit the slot designed for the con-
trol panel, housing is not seated correctly.
Press down firmly an on the rear of the housing. You will
feel the housing snap into place.
Replace plastic nuts over threaded inlet and outlet ports.
Tighten with channel lock pliers. Replace shut off valves.
Chiller is now ready for operation. Once water is flowing
through chiller, check carefully for any leaks.
You may now operate your UV sterilizer.
