Charging
Ensure that you use the correct charger. This unit uses a 9V DC
regulated charger.
Ensure that the batteries are fitted in the correct manner, and then
charge for at least 16 hours. Subsequent charges should be overnight.
NiMH batteries may be charged at any time, even for short periods to
conduct testing.
WARNING!
Under
NO
c i rcumstance should you expose batteries to ex t reme heat or
f i re as they may explode and cause injury. Always dispose of old batteries
p romptly in a manner consistent with local disposal re gu l a t i o n s .
Emptying and Cleaning the In-line Water Trap
The in-line water trap should be checked and emptied on a regular
basis. Water vapor will condense in the probe line, which may cause the
water trap to fill suddenly if the probe is moved. Care should be taken
at all times.
Carefully remove the rubber plug from the bottom of the water-trap
housing. Dispose of the condensate in a suitable drain, care must be
taken as it could be acidic.
If condensate spills onto the skin or clothing, clean off immediately
using fresh water, seek medical advice if problems occur. Ensure plug is
replaced before performing combustion tests.
Changing the Particle Filter
This is a very important part of the analyzer and should be changed
regularly. It prevents dust and dirt particles from entering the pump
and sensors that will cause damage. The filter MUST be changed when
it appears discolored.
Remove water-trap assembly from the analyzer as shown above.
Remove the filter and plastic holder from the housing. Discard the filter
element but keep the holder to fit to the new filter. Clean the inside of
the filter housing with a suitable soft cloth. Fit the holder onto the new
filter element and then insert into the housing. Refit the housing onto
the analyzer.
