OPERATION
Switch the Dual VSD Pump System on and allow pump to
prime. Turn each faucet and fixture off as flow becomes steady
and free of air. Pump should shut off shortly after last faucet
is closed. If pump does not turn off automatically, check for
plumbing leaks and/or continue to bleed air from plumbing sys-
tem.
Pump is now ready for automatic operation. It will start when
faucet(s) open and stop when faucet(s) close. If pump will be
inoperative for an extended length of time, turn pump circuit
off and open a faucet momentarily to relieve system pressure.
WARNING
Remove electrical power from pump
before servicing equipment.
