Manual Fan Override Switch - SPAL FAN-PWM-V3 Instructions For Use Manual

Manual Fan Override Switch

This will allow your cooling fan to run anytime the override switch is ON.
WARNING: There is a 15 second delay after you flip the switch ON and a 30 sec-
ond delay after you flip the switch OFF. After you turn the switch ON the FAN(s)
will go to Full speed after the 15 second delay. The FAN(s) will stay on high until
the 30 second delay is complete. If the switch is turned ON and OFF repeatedly
the delay will restart after the last time the switch was turned ON or OFF.
**SPAL USA suggests this override switch also trigger the electric water pump
relay. This will allow a single override switch to control both the fan and elec-
tric water pump.**
Note: 1. The fan will continue to run indefinitely if the switch is not shut off.
2. When running for extended periods of time, the voltage should be
MANUAL FAN OVERRIDE
