1.0 Introduction1.0 Introduction
1.1 The pump assembly
The pump assembly is a fixed flow device used to supply sample air at the correct flow rate to all ENMET portable
instruments models.
1.2 Intrinsic Safety:
The pump is designed to be nonincendive as defined by the National Electrical Code.
WWARNINGARNING: Do not change electrical components. In particular, do not use a different battery
pack or charger than the one designed for use with the pump. Substitutions may affect the
nonincendive design of the pump; personal injury, death, and property damage may result
from an explosion.

3.0 Operation3.0 Operation
3.1 Charging:
Charge the pump assembly battery by plugging the charger into an appropriate wall socket and the charger plug into
the jack on the pump assembly. Charge for 14 - 16 hours
WWARNINGARNING: Do not charge in a hazardous atmosphere as defined by the national electrical code.
Property damage, injury, or death may result if an explosion occurs.
3.2 Fittings:
Attach the air output line fitting to the mating fitting on the instrument or associated sensor cover. Attach the input
device selected, wand assembly or hose assembly to the air input line fitting.
3.3 Mountings:
The pump assembly is equipped with a belt clip, used to attach the pump to a belt, pocket or harness strap.
To mount the pump on an instrument:
• Remove the belt clip. Note: The screws also hold the internal circuit board in place.
• Replace the screws.
• Using the four pieces of adhesive backed Velcro supplied with the kit , two with hooks and two with loops.
• Remove the protective paper, stick these to the pump and instrument, and use them to mount the pump on the
instrument.
3.4 Turn Pump On:
Supply electrical power to the pump motor by putting the POWER Switch in the on position (S /N below 1000) or by
pushing the POWER Switch. The Red LED and associated AUDIO ALARM may activate momentarily; this is
acceptable.
Observe that the green ON LED is lit, and listen for the noise made by the pump. Units with S/N 1000 and above
are very quiet.
3.5 Use:
Use the pump assembly as required to supply appropriate sample air to the instrument.
3.6 Alarms:
Audio alarm and red LED indicate either air flow interruption or low battery voltage.
CAUTION: If at anytime during use of the pump the alarms are activated, discontinue use of the pump. If in a confined
space or other potentially dangerous location leave immediately
3.7 Shutdown:
When use is no longer required, turn the pump off, remove the sensor cover from the instrument, and disassemble
the pump kit as required for storage.
CAUTION: Failure to remove sensor cover from instrument will cause the gas detector to be ineffectual for ambient air
monitoring.
