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)
NOTE: The MANUFACTURER IS NOT RESPON- SIBLE for these adjustments.
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.
