General Maintenance
Pentair recommends that you inspect your heater on a
continual basis and especially after abnormal weather
conditions. The following basic guidelines are suggested
for your inspection:
1. Make sure the front of the unit is accessible for future
service.
2. Ensure the top and surrounding areas of the heater
are clear of all debris.
3. Ensure all plants and shrubs are trimmed and away
from the heater.
4. Keep lawn sprinkler heads from spraying on the
heater to prevent corrosion and damage.
5. Do not use this heater if any part has been under
water. Immediately call a qualified professional
technician to inspect the heater and replace any part
of the control system which has been submerged.
Every six months and start of every pool season:
6. Test the operation of the pressure relief valve by lifting
the valve lever (if installed).
7. Test for proper operation of the water pressure switch.
See Water Pressure Switch Adjustment on page 23
for testing instructions.
Every year and start of every pool season:
8. A qualified service technician should inspect and
clean the TitanTough™ Titanium Heat Exchanger
assembly (see Figure 24).
9. A qualified service technician should inspect the
burner, spark electrode, electrode wiring (not shown),
flame sensor rod and thermal insulation for signs of
damage or deterioration. (see Figure 24).

Condensate Drainage
The UltraTemp ETi™ Hybrid Heater will produce
condensation (water) while the heat pump is in operation.
The heater base is designed to allow the condensation to
exit through the bottom drain port when the unit is running.
The condensation will increase as the outdoor air humidity
level increases. Check the following at regular intervals to
ensure proper condensate drainage:
1. Visually inspect and clear the drainage connection and
hose of any debris that could clog the ports. Refer to
page 7, Heat Pump Drainage Connection to ensure the
drain barb and hose are installed correctly.
2. Keep the top air flow discharge and air flow intake area
clear of debris so the air flow though the heater is not
restricted. The cooler discharge air from the top should
not accumulate and be drawn into the side air intake
coils.
3. Be sure the condensate run-off is properly directed
away from the equipment pad to keep it from
undermining the pad.
4. Be sure the condensate water does not puddle inside
the heater. To be sure it is condensate water, check for
the absence of chlorine.
During normal operation, the heat pump produces three to
five gallons of condensate per hour. If condensate drainage
is above this range during operation or if water continues
to drain from the base when the heater is not in operation
for more than an hour, a leak in the internal plumbing
may have occurred. Call a qualified heater technician to
investigate the problem.
