Honeywell Gas Detector PHD6

Warning: The PHD6 must be located in a non-hazardous location during the charging cycle. Charging the PHD6 in a hazardous location may impair intrinsic safety.

Warning: Do not charge the PHD6 with any charger other than the appropriate PHD6 charger manufactured by Honeywell Analytics. Standard versions of the PHD6 must be charged with the UL/CSA-approved charger, which is part number 54-54-001. European versions of the PHD6 must be charged with the ATEX-approved PHD6 charger.

Verify that the instrument is turned off.

Remove the two screws that hold the inlet port to the pump

Gently pull the dust filter holder free of the pump

Remove and replace the dust filter that is located in the holder

Use a small screwdriver or other object to punch through the filter and remove it. The gasket that sits between the inlet port and the filter should come out with the filter

Place the new hydrophobic filter with the filter side down in place of the one removed in step 4. The gasket should be located on top of the filter and should sit against the dust filter holder

Replace the dust filter holder (which now has a new filter in it) and secure it with the two screws removed in step 1

PID sensor removed from the PHD6

Stack removed from the top of the sensor

Stack and lamp removed from the sensor body

Used lamp, stack or both discarded and rebuilt with replacement part(s)

Spring dropped into the center of the sensor body

Access the threaded sample probe handle to reach the filters

Particulate filter held in place by clear filter cup

To replace the particulate filter, remove the old filter and cup

Insert a new filter into the cup

Slide the cup back into place in the probe handle

The hydrophobic barrier filter fits into a socket in the rear section of the probe handle

The narrow end of the hydrophobic barrier filter is inserted towards the rear of the handle

To avoid accidentally introducing particulate contaminants into the system, turn the sample probe upside-down prior to removing either the hydrophobic filter or the particulate filter
