5. Disconnect the copper tubing from the pressure
switch fitting (see Figure 24).
6. Cover the vent grille so that snow will not
accumulate in the combustion blower, where it may
freeze.
To reactivate the heater in the spring, have a
qualified professional technician reassemble the heater as
follows:
1.
Attach the pressure switch fitting to the copper tubing
(see Figure 24).
2. Tighten the drain plugs in the headers.
3. Uncover the vent grille.
4. Turn on the main supply gas cock outside the heater
jacket.
5. Turn on the heater according to the lighting and
shutdown instructions on the back of the heater door.
6. During the winter shut down the heater by following
the lighting and shutdown instructions in Section 3A.
When on vacation for longer than a week, make sure
the heater is shut off at the temperature control panel.
7. Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other
landscaping, cabanas, or fencing.
8. Always use a pool cover when practical. Besides
providing a valuable safety feature, a pool cover will
reduce heat loss, conserve chemicals, and reduce the
load on filter systems.
3G. Seasonal Care
3G-1. Spring and Fall Operation
During periods when the pool is only going to be
used once in a while, set the thermostat control to the
lowest temperature for both modes. This prevents the pool
from becoming "chilled," yet still requires the least amount
of time to raise the water back up to swimming
temperature.
If the heater is not going to be used for a long period
of time, shut it down completely, following the
instructions in Section 3C-2 'Shutdown', or the lighting
and shutdown instructions posted inside the heater.
3G-2. Winterizing
If you don't plan to use the pool or spa over the
winter and your area is subject to freezing temperatures,
have a qualified professional technician perform the
following steps to protect the heater:
1.
Shut off the heater's gas valve according to the
lighting and shutdown instructions.
2. Shut off the main supply gas cock outside the heater
jacket.
3. Completely drain the heater before the first frost. To
drain the heater, remove the drain plug from the right
side of the inlet/outlet header (see Figure 23).
4. Return the drain plug to the manifold, but do not
tighten.

3H. Periodic Inspection
Improper installation or maintenance can
cause nausea or asphyxiation from carbon
monoxide or flue gases which could result in
severe injury, property damage, or death.
3H-1. Owner Inspection
Waterpik Technologies has designed and constructed
the LX heater to provide long performance life when
installed and operated properly under normal conditions.
The following basic guidelines should be maintained:
1.
Keep the top of the heater clear of all debris, and
make sure there is no collecting of flammable
materials, leaves, paper, etc., around or beneath the
heater.
2. Keep the pool heater area clean and free of all
combustible materials, gasoline and other liquids,
and vapors.
