WINTERIzATION OF YOUR ULTRA UV UNIT
If you are in a climate where you run your pool, spa, water feature, pond year
round, be sure that the flow to the unit continues during any periods of below
freezing temperatures. Failure to do so will cause damage to the unit.
Option #1 - Removing the unit for the winter. Turn off the power to the unit.
Remove the drain plug and allow all
of the water to drain from the unit
(Fig. 28). Disconnect the unions on
the plumbing to ensure that the unit
is completely drained. Now, with
the power off, disconnect the unit
from its power source and place
the drained unit in a safe place
that has a sustained temperature
above freezing. Reinstall after the
temperatures are considerably
above freezing.
Option #2 - Leaving the unit
in place for the winter. Turn off
the power to the unit. Remove
the drain plug and allow all of
the water to drain from the unit.
Disconnect the unions on the
plumbing to ensure that the unit
is completely drained. There is a
cup in the bottom of your unit that
the quartz tube nests in. This cup
does not drain completely (Fig.
28). To remove the water from
this cup you must first remove
the lamp array and quartz tube
(See page 11). Turn the unit on its
side with the unions facing down
until all of the water has drained.
Reconnect the unit, replace the
drain plug, quartz tube, lamps, and
cover. You may store the lamps
and quartz tube in a safe place.
Another way to remove the water
from the unit is to insert a wet dry
vac into the unit and suck out the
water from the cup in the bottom of
the unit.
