Installation Manual
• If the pool is only going to be used on weekends,
reduce the heater temperature control setting by 4
or 6 degrees during the week. Reset it to the 26°C
(79°F) level a day or so before you plan to use the
pool.
• During the winter or when on vacation for longer
than a week, shut down the heater by following
the shutdown instructions found in
Section 9.8 and
Figure 24
. and on the inside of the heater.
• Where possible, shelter the pool from prevailing
winds with well-trimmed hedges or other
landscaping, cabanas, or fencing.
• The greatest source of heat loss in a swimming
pool is through evaporation. It can accounts for
50% of pool systems total heat loss. The use of
solar blankets, automatic covers or anything that
limits the air’s access to the surface of the water
will help reduce this heat loss and minimize
evaporation.
10.4 Winterizing
In areas where freezing temperatures occur in winter
and the pool or spa will not be used, the pool should
be winterized by a qualified pool service technician:
• Turn off the electrical supply and the main gas
supply to the heater.
• Remove the heater access panel.
• Turn off gas supply to the heater following the
shut-down instructions.
See
Section 9.8 and Figure 24
.
• Remove the drain plug from the inlet/outlet
header and completely drain the heater before the
first frost.
• Inspect the gasket on the drain plug. Store the
drain plug in a safe place for winter.
• Cover the exhaust vent grill with plastic so that
snow will not accumulate and freeze on top of the
combustion chamber.
• Remove and drain the copper tubing for the water
pressure switch.
