6.2 Service Technician Maintenance
wARNING
This pump must be serviced by a professional
service technician qualified in pool/spa installation.
The following procedures must be followed exactly.
Improper installation and/or operation can create
dangerous electrical hazards, which can cause
high voltages to run through the electrical system.
This can cause property damage, serious personal
injury, and/or death. Improper installation and/or
operation will void the warranty.
