During periods when the pool is only going to
be used occasionally, set the pool and spa control
temperatures to 70°F (21°C) on the Legacy, see
Section 7.3.2. This prevents the pool water from
becoming chilled, and minimizes the time required
to raise the pool water back up to the desired
temperature.
If the heater is not going to be used for a long
period of time, shut it down completely. Follow the
instructions found on the inside of the heater, or refer
to Figure 21 of this manual.
In areas where freezing temperatures occur in
winter and the pool or spa will not be used, have your
service technician perform the following steps:
1. Turn off the main gas valve to the heater, outside
the heater jacket.
2. Remove heater door.
3. Shut down the heater following the shutdown
instructions found on the inside of the heater or
refer to Figure 21.
4. Remove the drain plugs from the inlet/outlet
header, and completely drain the heater before
the rst frost. See Figure 24.
5. After all water has drained from the heater, check
for mineral buildup in the openings.
6. Use compressed air to blow out any standing
water remaining in the heat exchanger.
7. Inspect the gaskets on the drain plugs and
reinstall plugs, but do not tighten.
8. Disconnect the pressure switch from the copper
tubing. See Figure 25.
To restart the heater in the spring, have a
qualied professional technician reassemble the heater
as follows:
1. Attach the copper tubing to the pressure switch.
See Figure 25.
2. Tighten the drain plug.
3. Make sure that power is supplied to the pump.
Turn on the lter pump and circulate water
through the heater for 5 minutes. Check for leaks
while circulating.
4. Turn on the main gas supply to the heater at the
gas cock outside the heater jacket.
5. Turn on the heater following the lighting instruc-
tions found on the inside of the heater, or refer to
Figure 21 of this manual.
Zodiac Pool Systems, Inc. designs and constructs
the heater to provide long performance life when
installed and operated properly under normal
conditions. Periodic inspections, especially at spring
start-up, are important to keep your heater running
safely and efciently through the years. Improper
maintenance can result in conditions where nausea
or asphyxiation from carbon monoxide or ue gases
could cause severe injury, property damage or death.
