Flush Valve Maintenance - Boss Water Systems 021-4PC Installation And Service Manual

This unit is fitted with a membrane-flushing valve and is normally closed. About once a
month Turn the Faucet on and drain the tank, at the same time turn the small red
or blue valve at the front of the unit to the open position and leave it on for about
10 minutes to clear any possible build-up of particles, failure to do this will
shorten membrane life. This flush valve needs to be operated when the tank is
filling, if you open the valve and nothing happens the system is in shut down
mode, release some water from the faucet to start the unit filling again and open
the flushing valve again. Drain the tank as part of the membrane flushing
process. When this valve is in the closed position it operates as a flow restrictor.

instructions, a full printed version is supplied in
