INPUT SYSTEM

The PK II tester features an input filter located within the 1/4

”

male tube fitting on the outside

of the PK II tester case. As this filter becomes dirty, the tester may react by not supporting
the weights. To correct, remove the filter and examine the NPT opening for any contamina-
tion.

CLEANING THE INPUT FILTER

Remove the input filter fitting and clean it by
backflushing from the downstream end with
clean compressed air. If an ultrasonic
cleaner is available, AMETEK recommends
that the filter fitting be cleaned using the ul-
trasonic cleaner for 10 to 15 minutes in a
residue-free solvent.

CAUTION

Do NOT attempt to remove the filter

element from the fitting.

Filters should be replaced periodically.
