SWIM SPA - CONTROLS: GENERAL MESSAGES
PRIMING MODE
Each time the swim spa is powered up, it will enter Priming Mode. The purpose of Priming
Mode is to allow the user to run each pump and manually verify that the pumps are primed
(air is purged) and water is flowing. This typically requires observing the output of each pump
separately, and is generally not possible in normal operation. Priming Mode lasts 4 minutes,
but you can exit it earlier by pressing any Temp button. The heater is not allowed to run dur-
ing Priming Mode.
NOTE: If your swim spa has a Circ Pump, it will turn on with Jets 1 in Priming Mode. The Circ
Pump will run by itself when Priming Mode is exited.
WATER TEMPERATURE IS UNKNOWN
After the pump has been running for 1 minute, the temperature will be displayed.
TOO COLD - FREEZE PROTECTION
A potential freeze condition has been detected, or the Aux Freeze Switch has closed, and all
pumps are activated. All pumps are ON for at least 4 minutes after the potential freeze con-
dition has ended, or when the aux freeze switch opens.
In some cases, pumps may turn on and off and the heater may operate during Freeze
Protection.
This is an operational message, not an error indication.
WATER IS TOO HOT - (OHS)
One of the water temp sensors has detected swim spa water temp 110°F (43.3°C) and swim
spa functions are disabled. System will auto reset when the swim spa water temp is below
108°F (42.2°C). Check for extended pump operation or high ambient temp.
DO NOT DIVE.
