2.
Remove the new 0.2 micron filter assembly from its
bag and insert it into the Luer fitting. Gently turn it
clockwise until it is fully seated in the the Luer fitting.
3.
Rinse at least one reservoir volume of water through
the filter to drain prior to using the product water.
Ventgard Cap Replacement
The purifying media and filter in the Ventgard filter element
have a limited capacity. Therefore, the Ventgard cap should
be replaced every 90 days. The Ventgard cap is shipped as
a complete unit; replacement involves simply removing the
new Ventgard cap from its plastic storage bag and placing
it on the reservoir. A Ventgard cap can be stored in a cool,
dry place almost indefinitely, provided its plastic storage
bag has not been opened.
General Cleaning Instructions
Wipe exterior surfaces with a lightly dampened cloth con-
taining mild soap solution.
System Sanitization
Frequency of cleaning is difficult to determine because of
variability in feedwater and usage. Cleaning is necessary
when residual deposits are evident inside the feedwater
reservoir or if a new 0.2 micron filter clogs rapidly after in-
stallation even though the cartridges were properly rinsed
before the 0.2 micron filter was installed. To sanitize the
EASYpure RF, the 0.2 micron final filter and the purification
cartridges must be removed. The purification cartridges
must be replaced with empty cartridges. These must be or-
dered separately. Contact Barnstead|Thermolyne and order
part number D7034.
1.
Drain the system.
a.
Place the filter over a sink or place a bucket or
other suitable large container under the filter and
draw off water as described under Water Draw
off in the Operation section of this manual.
Draw off water until the water level in the feed-
water reservoir is lowered to the point that the
pump protector switch disables the pump. Lift
draw-off valve to closed position.
b.
Disconnect the unit from the power supply.
CAUTION
Do not overtighten the 0.2 micron filter assem-
bly onto the Luer fitting or use excessive force
in seating it. The filter and/or Luer fitting can be
damaged by overtightening or excessive force.
NOTE
If a newly installed 0.2 micron filter clogs rapidly
after installation, the EASYpure RF may need to
be sanitized to remove bacterial contaminants.
