RELEASING AIR TRAPPED IN FILTER...
• When the pump starts circulating, it will be necessary to
release trapped air in the filter. Carefully loosen the air vent
valve counter-clockwise until there is the hissing sound of air
escaping. Once there is a steady stream of water, close the
vent valve, ensuring that the o-ring does not become
pinched.
• Turn the Hydrotherapy pump(s) on and re-check for leaks.
The control system will automatically return the pump(s) off
after 15 minutes.
• Adjust the hot tub heat control at the topside panel to the
desired water temperature.
• Adjust water balance (pH, TA, calcium hardness) to recom-
mended levels and add sanitizer once the water temperature
reaches 20
o
C (68
o
F).
See section SWIM SPA WATER BALANCE
• Keep insulated safety hard cover on the hot tub, and the
air controls closed during the entire heat up process.
