Additional Notes on Pump Operations
1. The pump is not self-priming. In order to avoid damage to the seal in the
pump, always fill the bathtub to at least 1” above the highest jet in the
system before starting the pump. This will not only ensure that the pump
will not run in a dry condition, but will also avoid water from being
discharged outside of the bathtub and causing a slipping hazard on the
floor.
2. The pump does not require periodic maintenance, or lubrication. It is
recommended that the pump and circulating piping be checked periodically
for leakage. It is also recommended that the Ground-Fault Circuit
Interrupter (GFCI) protecting the pump electrical circuit be tested per the
GFCI manufacturers instructions.
3. This pump is protected by an automatic thermal overload protection
device. The motor will automatically shut off due to low voltage, overload,
blockage, or other abnormal conditions, before heat damage can occur to
the pump. The pump will then restart when a safe operating temperature
is reached. Should this occur, the cause of overheating must be
determined by the tub manufacturer or qualified service personnel and
resolved for further proper operation.
4. The ambient temperature classification for PB-series Brush Motor pumps
is 104°F (40°C); Hercules II PX-series pumps is 122°F (50°C).
5. The pump has been designed and tested to give trouble-free operation. If
the system does not operate as described, stop the pump and contact the
bathtub manufacturer or qualified service personnel.
WARNING: All service performed on the whirlpool system must be
performed by a qualified service technician in accordance with applicable
codes. Before working on electrical equipment, be certain that all the
power feeds are off at the source.
