heat pump's long life. Be sure to keep your chemical and mineral concentration levels within the
values indicated in the table below. Failure to maintain proper water chemistry may cause damage
to the UltraTemp® Heat Pump and may void the warranty.

Inspection and Service

Pentair Heat Pumps are designed and constructed to provide long performance life when installed
and operated properly under normal conditions. Periodic inspections are important to keep your
heat pump running safely and efficiently through the years. Failure to properly maintain your unit
can void the warranty.

Owner Inspection

Pentair recommends that you inspect your heat pump 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. Keep the top and surrounding areas of the heat pump clear of all debris.
3. Keep all plants and shrubs trimmed and away from the heat pump.
4. Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage.
5. If the unit is installed under a roof edge, install a gutter or diverter to prevent excessive water
and debris from pouring down into the unit.
6. Do not use this heat pump if any part has been under water. Immediately call a qualified pro-
fessional technician to inspect the heat pump and replace any part of the control system which
has been submerged.
