by the use of sampling adaptors installed in place of or in
combination with the differential pressure device. For more
information consult Pall or your local Pall Distributor.

Warranty, Limitation of Liability and
Remedies
THERE IS NO WARRANTY OF MERCHANTABILITY OR
FITNESS FOR ANY PARTICULAR PURPOSE WITH RESPECT
TO ANY OF THE PRODUCTS, NOR IS THERE ANY OTHER
WARRANTY EXPRESS OR IMPLIED, EXCEPT AS PROVIDED
FOR HEREIN.
For a period of twelve months from the date of delivery
from Seller or three thousand hours of use, whichever
occurs first (the “Warranty Period”), Seller warrants that
products manufactured by Seller when properly installed and
maintained, and operated at ratings, specifications and
design conditions, will be free from defects in material and
workmanship. By way of explanation and not limitation,
the Seller does not warrant the service life of the filter element
as this is beyond the Seller’s control and depends upon the
condition of the system into which the filter is installed.
Seller’s liability under any warranty is limited solely (in Seller’s
discretion) to replacing (FOB original ship point), repairing
or issuing credit for products that become defective during
the Warranty Period. Purchaser shall notify Seller promptly in
writing of any claims and provide Seller with an opportunity
to inspect and test the product claimed to be defective. Buyer
shall provide Seller with a copy of the original invoice for the
product, and prepay all freight charges to return any products
to Seller’s factory, or other facility designated by Seller. All
claims must be accompanied by full particulars, including
system operating conditions, if applicable.
Seller shall not be liable for any product altered outside of
the Seller’s factory except by Seller or Seller’s authorized
distributor, and then, as to the latter, only for products which
have been assembled by the distributor in accordance with
Seller’s written instructions. Nor shall Seller be liable for a
product subjected to misuse, abuse, improper installation,
application, operation, maintenance or repair, alteration,
accident or negligence in use, storage transportation or
handling. In no event will Seller be liable for any damages,
incidental, consequential or otherwise, whether arising out of

Filter element installation / servicing
During servicing the external surfaces of the filter assembly
must be cleaned to remove any dust deposits.
Servicing must be conducted using suitable tools that do not
present a hazard. Servicing must also not be carried out when
a potentially explosive atmosphere is present.
Refer to product data sheet for item numbers for applicable
replacement element series. Remove and replace element
as follows:
7.1 Turn off and depressurize the system.
7.2 Unscrew and remove the filter bowl assembly (2) from
head (1) counter-clockwise when viewed from below.
7.3 Element replacement (G300 Series): Remove filter
element (5) by turning clockwise ¼ turn and pulling
down. Carefully inspect the surface (flow through the
element is out-to-in) for visible contamination. Normally
no dirt should show, but visible dirt or particles can be
an early warning of system component failure. Discard
both the filter element and its O-ring. The filter element
is NOT CLEANABLE. Any attempt to clean the filter
element can cause degradation of the filter medium
and allow contaminated fluid to pass through the
filter element.
7.4 To replace the filter element, lubricate element O-ring
with clean system fluid, align arrows on filter element
end cap to arrows on the filter head. Push up and
rotate anti-clockwise through ¼ turn to a stop. Use the
replacement filter as indicated by the part number on
the element end cap.
7.5 DO NOT run the system without a filter element installed.
Check that the O-ring between the bowl (2) and head (1)
is not damaged. Replace if damaged. It is recommended
that the o-ring head to bowl seal is changed at each
element service.
7.6 Lightly lubricate head-to-bowl O-ring with clean system
fluid. Lubricate the threads of the filter bowl with a
suitable anti-galling compound and reassemble the
housing until thread bottoms. The bowl should be torque
tightened to 18 ft/lb or 25 Nm.
Caution: do not over
torque the bowl.
O-ring sealing is not improved by
over tightening
7.7 Bleed the system and check for leaks as per section 4.8.
7.8 After element change ENSURE DIFFERENTIAL
PRESSURE DEVICE IS RESET; both visual and electrical
switches reset automatically. When system reaches
normal operating conditions, check that the electrical
switch has not actuated and/or the visual warning button
has returned to white.
WARNING:
FAILURE TO DEPRESSURISE THE FILTER BEFORE
SERVICING ELEMENT COULD RESULT IN EXPLOSIVE
LOSS OF FLUID, DAMAGE TO EQUIPMENT AND
POSSIBLE PERSONAL INJURY.
WARNING:
DO NOT ATTEMPT TO CLEAN OR RE-USE THE
ELEMENT.
CAUTION:
Filter elements should be replaced upon indication
or at specified intervals, six months maximum is
recommended. Failure to change the element will cause
the filter to go on bypass.
