Honeywell Gas Detector PHD6

CAUTION! Always turn the PHD6 off prior to removing the battery pack. Removal of the battery pack with the instrument turned on may cause corruption of stored data in the PHD6.

WARNING! The PHD6 must be located in a non-hazardous location whenever alkaline batteries are removed from the alkaline battery pack. Removal of the alkaline batteries from the battery pack in a hazardous area may impair intrinsic safety.

WARNING! Use only Duracell MN1500 or Ultra MX1500, Eveready Energizer E91-LR6, Eveready EN91 batteries. Substitution of batteries may impair intrinsic safety.

PHD6 located in a non-hazardous location?

Are you using the correct batteries?

Loosen the top center screw on the back of the instrument

Gently pull the top of the battery away from the instrument

Remove the battery once the top clears the upper housing by pulling up and away

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.

Power supply plugged in and red LED labeled “Power” is lit.

PHD6 inserted into the charging cradle bottom side down with the display facing forward.

Green LED on the charger labeled “Charge” is blinking while the battery is charging.

When the battery is fully charged, the green “Charge” LED is lit and not blinking.

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

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

Sign off on the pump filters replacement

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
