Repairing this equipment requires access to parts
which may cause electric shock or other serious injury
if work is not performed properly. Electrical trouble-
shooting must be done by a qualified electrician. Be
sure to shut off all power to the equipment and lock out
power at the source before repairing.
Flush equipment only in a well-ventilated area. Do not
spray flammable fluids. Do not turn on heaters while

Trapped air can cause the pump to cycle unexpectedly,
which could result in serious injury from splashing or
moving parts.
