INTRODUCTION
Thank you for choosing to install the Stingl-Switch Model SR-500 on your
swimming pool, hot tub, or spa. The enclosed information is designed to give you
years of safe operation of your Stingl-Switch. Please closely review this important
product information.
The Stingl-Switch Model SR-500 works by monitoring the vacuum on the influent
side of the pool or spa pump. Whenever a blockage occurs in the pool drain or
skimmers, the sudden rise in vacuum will cause the Stingl-Switch to immediately
shut down pump operation and activate an audible alarm. The pump will remain off
and the audible alarm will sound until manually reset.
The Stingl-Switch Model SR-500 provides a 30-minute Maintenance/Cleaning
mode to allow pool vacuuming. Normally, the high vacuum generated by pool
vacuuming would cause the Stingl-Switch to sense an entrapment condition and shut
off the pump. However, in the Maintenance/Cleaning mode, the Stingl-Switch is
DEACTIV
ATED
and the pump is allowed to run under a high vacuum situation.
W
ARNING: DURING MAINTENANCE/CLEANING MODE VACUUM IS
NOT MONITORED. A BLOCKAGE WILL GO UNDETECTED DURING
THE 30-MINUTE CYCLE, INCREASING THE RISK OF ENTRAPMENT.
*No bathers should be allowed in pool/spa while Maintenance Mode is in use.
To prevent the system from being left accidentally in Maintenance/Cleaning mode,
the audible alarm will be activated whenever the switch is in this mode. The pool,
hot tub, or spa should not be used or left unattended while servicing or cleaning in
the maintenance mode.
The Stingl-Switch Model SR-500 is designed to be easily retrofitted on all existing
pools, hot tubs, and spas, and is easily installed during new pool and spa
construction.
