Operation

AUTOMATIC SYSTEM ACTIVATION HAZARD
Unexpected activation of the system could result in
serious injury, including skin injection and amputa-
tion.
This device has an automatic timer that activates the
pump injection system when power is connected or
when exiting the programming function. Before you
install, service, or remove the pump from the system,
pull the motor fuse (see pump manual) and discon-
nect and isolate all power supplies.

Cool Down Mode

When the controller detects that it is too hot, it will turn
the pump off and display "HOT". Once it has cooled
down, the controller will automatically resume running.
