Service Call Verification
Before you make a service call, first determine if the
problem is:
• Warranty Service
• Unit operation (power supply, water flow, or time
clock adjustment)
Power Supply
• Verify that all circuit breakers are reset and work-
ing properly.
• If the temperature display or the Power lamp on
the control panel still does not light, contact the
installing dealer, since it may be a power problem
requiring an electrician.
Water Flow
• Verify that the pool filter is clean to provide good
flow.
• Verify that valves are properly positioned to allow
adequate water flow through the unit.
• If the Water Flow lamp (analog models) on the
control panel still does not light, and water is circu-
lating in the pool, verify that all valves are
positioned correctly.
Time Clock Adjustment
Verify that the time clock is set to permit the unit to run
long enough to heat properly.
