Notes
Contact Dealer
Only if Booster Pump is not
installed.
Contact Dealer
Only if Beverage Booster
System is not installed
Feed Water Pressure,
Temperature, RO
Membrane Flow Rate
should be checked before
replacing Membrane
Unscrew Blue Cap to
Access Schrader Air Valve
A more frequent pre-filter
change-out schedule may
be needed or use
HF60-CL or HF90-CL for
high sediment load area
The unit produces water
slowly. A dripping leak
can prevent the tank from
filling
High levels of hardness
minerals may be present
in feed water, monitor
reject flow for plugging,
contact dealer to add a
water softener
Reject Water flow to drain
should stop when the feed
water valve is off.
