Note:

 When the Carbon Purge/Zero Air filter is saturated and can no longer absorb refrigerant, 

refrigerant can pass through and offset the baseline measurements of the unit which will than result in 

unit going into fault condition <0100> error will appear. Please adhere to filter maintenance intervals 

as below recommended.

The monitor is powered by a rechargeable battery pack located in a pouch on the side of the monitor’s 

soft carrying case. The battery pack can be recharged at any time, regardless of the battery’s current 

charge state.  The lithium-ion battery will likely be partially charged. However, you should fully charge 

the battery prior to operating the PGM-IR. Refer to the battery manufacturer’s instruction sheet for the 

proper charging procedure.

Before the unit can be used please connect the battery pack the unit is designed for a 16 V DC input. 

Set battery voltage output to 16 V (refer to the battery manufacturer’s instruction sheet for details).

A fully charged battery pack will power the monitor for a minimum of 8 hours.
