Housing
The Model 1017-05’s cast aluminum alloy housing is rated as explosion proof for Class I
Groups B, C, & D.
The housing has a screw-on cover on the front which may be removed for access to the
internal components. It also has two integral mounting feet, one on the upper right corner
and one on the lower left corner, for use with 3/8” mounting bolts or screws.
The inlet and exhaust fittings are installed on the bottom of the housing. A 3/4” NPT
conduit opening is on the right side of the housing to allow for wire entry. The subpanel
assembly is mounted to the interior of the housing.
Inlet & Exhaust Fittings
The inlet and exhaust fittings on the bottom of the housing allow the gas sample to enter
and exit the Model 1017-05. They are made of stainless steel. The inlet fitting is on the
right and the exhaust fitting is on the left. The fittings accept 1/4 inch O.D. rigid metal
tubing. See the Installation section on page 4 to connect tubing to the inlet and exhaust fit-
tings. Figure 2 below illustrates the flow path of the sample inside the Model 1017-05.
