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.
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.
Before first power up connect all necessary accessories as described on below, this will ensure correct
functionality of the unit.
To connect the gas-sample probe to the monitor, connect the probe to the gas sample port (see
picture below).
A Purge/Zero Air Carbon Filter must be installed to properly use the Portable Aspirated Refrigerant
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.
