Winter Operation - Waterco Turbotemp 200HD Installation And Operation Manual

WINTER OPERATION

!
CAUTION
Operating this heater continuously at water temperatures below 20° C (68° F.) will
cause harmful condensation and will damage the heater and void the warranty.
• If the heater has been drained for freezing condition, do NOT turn "ON" until the
system is circulating water.
• Water trapped in the heat exchanger can result in freeze damage to the exchanger
or headers. Freeze damage is specifically not covered by the warranty.
• When starting the heater for the swimming season with a water temperature below
10° C (50° F), the heater may be used to heat the water; however, make sure that
the heater operates continuously until the water temperature reaches the heater's
minimum setting of 20° C (68° F). During cold weather, if there is no danger of
freezing, operate the filter pump continuously even if the heater is not operating.
If air temperatures are expected to drop below freezing 0° C (32° F), shut down the
heater and winterize it.
For outdoor heaters in freezing climates, shut the heater down and drain it for winter as follows:
1. Turn off electrical supply to the heater and pump.
2. Close the external manual shut-off gas valve (located outside the heater).
3. In colder climates where they may be required, open drain cock located on the bottom of
the manifold adapter, and drain the heat exchanger and manifold adapter completely. If
heater is below pool water level, be sure to close isolation valves to prevent draining the
pool (isolation valves are not required and should not be used on heaters installed above
pool water level except when needed for winterizing valves). Assist the draining by blowing
out the heat exchanger through the pressure switch fitting with low pressure compressed air
(less than 35 kPa or 5 PSI).

WARNING
Explosion hazard. Purging the system with compressed air can cause components to
explode, with risk of severe injury or death to anyone nearby. Use only a low pressure (below
35 kPa or 5 PSI), high volume blower when air purging the heater, pump, filter, or piping.
4. Remove the Water Pressure Switch. Plug the port in the manifold to prevent bugs and dirt
from getting into the manifold.
5. Drain the plastic inlet/outlet manifold through the outlet pipe. If the pipe does not drain
naturally to the pool, install a drain cock in the outlet pipe to drain the manifold.
6. Cover air inlet grate with a plastic bag to prevent bugs, leaves, etc., from getting into the heater.
NOTICE: Water trapped in the heater can cause freeze damage. Allowing the heater to
freeze voids the warranty.
To return the heater to service after winterizing:
1. Close drain cock and fittings.
2. Before starting the heater, circulate water through the heater for several minutes until all air
noises stop. See also "BEFORE START-UP" (page 34) and "CARE AND MAINTENANCE"
(page 48).
