Hazardous area warning:

This instrument has not been designed to be intrinsically safe for use in areas classified as hazardous locations. For your safety, DO NOT use it in hazardous (classified) locations.

Do not operate this equipment in the presence of flammable liquids, vapours or aerosols.

Combustible/flammable gas warning:

This is NOT a safety device. Some gases which this instrument can detect may be combustible/ flammable. When properly configured, this instrument is designed to alarm at concentrations that are lower than the explosive limit of the gas. As such, it is the buyer’s responsibility to initiate an immediate planned response to any gas leaks as soon as they are detected. This equipment should NEVER be used to measure or sample gases at or above their respective lower explosive limits. Operation of any electrical equipment in such an environment constitutes a safety hazard.

Warning:

A gas monitor is a delicate and complex device and it is not to be used in any application that is beyond its intended purpose or beyond the scope of its specifications. For details on appropriate use, refer to the general description, application, and operation discussions in this manual. Before risking equipment damage or personal injury, contact the manufacturer if you are unsure of the validity of a particular gas monitor application.

Warning:

A potential risk exists if the operating instructions are not followed.

	Warning:
	To avoid risk of injury from electric shock, do not open the enclosure when power is applied.
	Caution:
	Except for the maintenance detailed in this manual, this product should ONLY be opened and / or
	serviced by authorized personnel. Failure to comply may void the warranty.

1. Visual inspection	When you receive the instrument, please unpack from it from shipping carton and perform visual
	check on the enclosure to ensure no damage to the external parts of the unit which might have
	occurred during shipment. Check that all the below items have been received.

Item	Qty.
Refrigerant monitor	1
Soft carrying case with shoulder strap	1
Battery pack and charger kit	1
Probe assembly	1
Coalescing filter	1
Carbon filter	1

PAGM-IR CO2 (code no. 080Z2148)

Item	Qty.
Refrigerant monitor	1
Soft carrying case with shoulder strap	1
Battery pack and charger kit	1
Probe assembly	1
Coalescing filter	1

2.Connecting gas-sample Before first power up connect all necessary accessories as described on below, this will ensure correct

	probe and exhaust and	functionality of the unit.
	zero air filter assembly

2.1	Gas-Sample Probe	To connect the gas-sample probe to the monitor, connect the probe to the gas sample port (see
		picture below).

2.2	Purge/Zero Air Carbon	A Purge/Zero Air Carbon Filter must be installed to properly use the Portable Aspirated Refrigerant/
	Filter Assembly	Gas Monitor (PAGM).

Filter installation:

1.Unfasten the Velcro on the front of the monitor soft case.

2.Slide the Purge/Zero Air Carbon Filter into the front pocket. Route the tubing through the hole in the back of the pocket, along the side of the housing.

3.Insert the connector extending from the Purge/Zero Air Carbon Filter into the Zero Air Inlet Port on the monitor.

4.Refasten the Velcro.

The Leak Detector will periodically (up to 4-minute intervals) draw clean air from an inlet port on the side of the chassis for the CO2.

The external Purge/Zero Air Carbon Filter must be connected to the intake port in order to absorb any refrigerant present in the area of operation.
