5. Installation
5.1 Notice
You cannot use at a place like below.
1) The place where the voltage of instrument power is very fluctuate,
2) The place where dusts or corrosion gases are remained
3) The place where the ambient temperature is above 60
℃
or below -20
℃
4) The place where dust or poisoning gas (VCM, Cl
2
) are existed
5) The place where the mechanical vibration or the shock are existed
6) The place near the high current circuit or where high induction interference is existed, an instrument
and a sensor circuit may keep away above 30 cm from the high current or the high voltage circuit,
because it makes induction interference and it would be an indication error and unstableness of
indication.
5.2 Installation method
1) When you install it to the wall, you may arrange the hole for fixation of detector. Please refer figure 5-1.
2) When you install it by a bracket, you may follow a special installation procedure.
3) When you install it to a outdoor, you may secure a sufficient installation area because detector need to
install with whether proof cover. Please refer to figure 5-2.
4) You may choose the installation point with due regard to following particulars.
(1) The place where a gas is accumulated
(2) You may select the installation place depend on the specific gravity of leakage gas
Detector Gas
Installation Place
Suggestions
Heavy GAS
(LPG, I-C4H10)
Below 20 cm from the
ground
You might avoid too low place for
calibration or repair operations.
Equal GAS
(Carbon monoxide)
Between 75 ~ 150 cm from
the ground
You may consider the specific gravity
and installation.
Light GAS
(CH4, LNG)
Close to roof as close as
possible
You may install in due consideration
of a step for repair operation.
