３．INSTALLATION
To install the Dust Monitor, use the one-inch socket that is provided.
Weld the socket onto the pipe. Install the Dust Monitor so it is horizontal or vertical.
Weld around the entire circumference of the pipe to prevent gas from leaking.
(
Attention in installation)
The Dust Monitor may malfunction under the following environmental conditions.
Do not install the Dust Monitor under such conditions.
4-1.In a location too close to the pipe flue or near the inflections.
4-2.In a location within a distance 1.5 times longer than the diameter or the length
of the duct measured vertically from the inflections.
4-3.Near the fan.
4-4.A pipe, short pipe, or duct that is nonconductive.
4-5.Any environment or conditions other than those in the specifications.
4-6.In a place where dust may accumulate between the short pipe and the probe if the short pipe
is used.
4-7.In a location where the gap between the end of probe and the pipe is 20 mm or less.
Importance:
The cap attached to lead outlet is for the transportation protection.
(The drip-proofness is not effective in the cap.)
Attention : When only one side of the cable gland is used , replace the unused side of the cable gland
and plug in order to maintain the protective structure.
Securely close the lead outlet to prevent outside air from entering in the main unit.
Do not remove the accessory silica gel. (for dehumidification)
Separately wire a power supply line and a signal line.
Where using conduit piping and so on instead of cable grand, be sure to apply putty
or like at cable entry so that ambient air does not come into the unit.
Importance: For installation of main unit, place Rc1 Attachment screw, then insert Probe and tighten
M5 bolt and nut on the side of Rc1 Attachment screw.
