燃烧器板上的孔，并使用三个六角带帽螺钉（未提供）固定。安装瞄准具旋转底座上的管道。如果未使用旋转接头，将观察管末端插入孔中，
将孔对准所需的观察角度并点焊（焊接必须足以支撑所安装扫描仪的重量）。观察管应倾斜布置向下，这样灰尘和污垢就不会聚集在里面。当通过运行测试确认观测结果令人满意时，固定转环通过拧紧位于旋转接头上的三个六角头螺钉，将支座的球定位到位安装环。
8、为了便于使用，扫描仪应安装在观察管上，以便LED显示屏可以轻松显示被阅读。
DS215SLCCG1AZZ01A电气卡件注：LED显示屏的操作与位置无关。扫描仪透镜和扫描仪外壳必须无污染物（油、灰、烟尘、污垢）
温度不得超过其最大额定值150°F（65°C）。温度过高会缩短扫描仪寿命。通过在以下位置连续喷射净化空气，可满足这两项要求
3/8“壳体入口或旋转底座前的1”Y“接头，如所示图5：。
扫描器的安装可以只通过3/8英寸的开口吹扫空气，或者通过3/8“开口或1”Y“接头净化空气。在后一种安排中，通常
两个接头中只有一个配有净化空气，另一个接头堵塞。使用密封联轴器，1“Y”接头用于净化空气，3/8”开口堵塞。
在所有装置上使用密封联轴器（P/N 60-1199-x，带NPT螺纹）是一种良好的做法确保不必要的炉压不会损坏扫描仪镜头。
DS215SLCCG1AZZ01A电气卡件在正常条件下，使用清洁燃烧的燃油和中等环境温度条件，吹扫大约4 SCFM（113 l/min）的空气流量通常足够。高达15 SCFM（425升/分钟）可能需要用于产生高水平灰分或烟尘的燃料，或用于高温环境将扫描仪的内部温度保持在规定范围内。
When a satisfactory sighting has been confirmed by operational testing, secure the swivel
mount’s ball position in place by tightening the three hex head cap screws located on the swivel
mount ring.
8.
For ease of use, the scanner should be installed on the sight pipe so the LED display can easily
be read.
Note: Operation of the LED display is independent of position.
9. The scanner lens must be kept free of contaminants (oil, ash, soot, dirt) and the scanner housing
temperature must not exceed its maximum rating of 150° F (65° C). Excessive temperatures will
shorten scanner life. Both requirements will be satisfied by a continuous injection of purge air at
either the 3/8" housing inlet or the 1" “Y” connection ahead of the swivel mount as shown in
Figure 5.
The scanner mounting may be made with provision for purge air through only the 3/8" opening or for
purge air through either the 3/8" opening or the 1" “Y” connection. In the latter arrangements, normally
only one of the two connections is provided with purge air and the other connection is plugged. When a
sealing coupling is used, the 1" “Y” connection is used for the purge air and the 3/8" opening is plugged.
It is good practice to use the sealing coupling (P/N 60-1199-x with NPT threads) on all installations to
insure against unwanted furnace pressures from damaging the scanner lens.
Under normal conditions, with clean burning fuels and moderate ambient temperature conditions, purge
air flow of approximately 4 SCFM (113 l/min) is generally adequate. Up to 15 SCFM
(425 l/min) may be required for fuels that produce high levels of ash or soot, or for hot environments to
maintain the scanner’s internal temperature within specification.
