ATTENTION:
BACKFLOW PREVENTERS ARE REQUIRED FOR EVERY SPA CHAIR. THEY MUST BE INSTALLED ON BOTH HOT
AND COLD WATER LINES TO AVOID LOSING HOT WATER FROM ONE CHAIR TO THE OTHER.
Sensor Delay Time Setting:
The sensor delay time can be adjusted by a knob located next to the blue light.
Depending on the knob position
(Fig. 4),
a valve shutoff delay time will be added after water reaches the
sensor. This delay allows the user to set the preferred water level in automatic fill mode.

How to operate the iFill 4 (
Be sure that the faucet is open)
ATTENTION:
IFILL 4 WILL RUN A SELF-CALIBRATION EVERY TIME THE SYSTEM IS POWERED UP. THIS
CALIBRATION REQUIRES THE TUB TO BE EMPTY (WITHOUT ANY WATER IN IT). BE SURE THAT THE TUB IS
EMPTY BEFORE SYSTEM IS PLUGGED TO POWER OUTLET.
