WINTERIZING
Option 1: If you are going to continually run water through your unit and it will be exposed to
freezing temperatures be sure to install winterizing caps (sold separately) on the unit and take all
the internal parts inside (Quartz Sleeve, EZ-Twist Top, Quartz Cap, Lamps, Rubber Seals, and
Small Transformers). NEMA Transformer Boxes may be left outside.
Option 2: If you are not flowing water through your system, use two winterizing caps with EZ Twist
O-Ring, drain the unit completely and take the internal parts inside. If the unit is not completely
drained, the water will freeze and crack the housing. This is not covered under warranty. Check
with the venturi manufacturer for winterization instructions.
Option 3: If you don't have a winterizing cap and are not going to run water through the
system, remove the Lamp, disconnect unions and take the entire unit inside.
Store the Lamp separately to avoid breakage.

CAUTION: Always turn off the pump and disconnect electricity from the unit prior to
