SAFETY ASPECTS
The Firetron 1000 portable flue gas monitor is a safety Class 2 instrument.
1.
Before switching on the apparatus make sure that the power supply is suitable for the instru-
ment.
2.
The main power plug shall only be inserted in a socket outlet provided with a protective earth
contact. The protective action must not be negated by the use of an extension cord without a pro-
tective conductor.
3.
WARNING! Any interruption of the protective conductor inside or outside the instrument
or disconnection of the protective earth terminal is likely to make the apparatus danger-
ous. Intentional interruption is prohibited.
4.
When the apparatus is connected to its supply, terminals may be live, and the opening of covers
or removal of parts (except those to which access can be gained by hand) is likely to expose live
parts.
5.
Any adjustment, maintenance and repair of the opened apparatus under voltage shall be avoided
as far as possible and, if inevitable, shall be carried out only by a skilled person who is aware of
the hazard involved.
6.
Make sure that only fuses with the required rated current and of the specified type are used for
replacement. The use of makeshift fuses and the short-circuiting of fuse holders are prohibited.
7.
Whenever it is likely that the protection has been impaired, the apparatus shall be made inopera-
tive and be secured against any unintended operation.
The protection is likely to be impaired if, for example, the apparatus:
- shows visible damage
- fails to perform the intended measurements
- has been subjected to prolonged storage under unfavorable conditions
- has been subjected to severe transport stresses.
CAUTION: Due caution should be exercised when installing, operating and servicing this
equipment. Attention is drawn to the following safety points:
POWER:
Ensure that main supplies are isolated when making access to the equipment for mainte-
nance or servicing purposes. Read the instructions carefully to ensure correct connection of all
mains, signal leads and probe connections.
EYE PROTECTION:
Eyes and face should be suitably protected by goggles when looking into hot
furnaces. Precautions should also be taken when removing instruments from pressurized ducts.
PROTECTIVE CLOTHING:
When working in the vicinity of hot boilers and furnaces protective
clothing should be worn at all times, particularly protection of the hands.
CAUTION: FAULT FINDING: The instrument must be fully isolated from the power sup-
ply before internal, electrical maintenance or servicing work, and should only be under-
taken by a suitably authorized/qualified engineer.
STATIC DISCHARGE
Under certain boiler conditions a high static charge may build up. With non conductive stack entry
points the normal procedure to avoid damage to the instrument or person, is to make a connection
from the probe extension to ground /earth before inserting into stack. With conductive (metallic)
entry points the metal surround should be grounded.
