Owner`s manual

OHH or OHS:
Over heat protection. If a malfunction occurs and
the spa water reaches 112°F (44°C), the system
completely shuts down. In such a condition, DO
NOT ENTER THE WATER. Turn off all power to
the spa and contact your dealer for service. Sev-
eral conditions could lead to overheating, for
example, low water level, shut-off valves closed
while heater is on, dirty filter, and restriction in the
plumbing lines. After the power if turned back on,
the spa will not restart itself until the water tem-
perature within the spa drops to a lower, predeter-
mined temperature. As a double safety feature, a
secondary high-limit sensor shuts the system off if
the water temperature in the heater housing
reaches 118°F (48°C). In this case, the spa may be
restarted by pressing any panel pad after the water
has cooled to 108°F (42°C). If the switch trips
repeatedly, do not use the spa and contact your
dealer for service.
