SHELTER INSTALLATION WITH ROOF PENETRATION

08354A DCN7303
The T640 can be installed in an indoor or outdoor shelter with roof penetration or
in an outdoor enclosure.
1. Determine the location of where the T640 will operate in the shelter.
•
The instrument should be in a location where the top of the ASC will be
no less than two feet from the top of the ceiling/roof line or,
•
The instrument should be placed at a height within the shelter so that
after the ASC and 8' extension sample line are installed, the inlet (on top
of the 8' extension sample line) is 2-m above the roof and equal height
with any other PM instrument inlets.
2. Drill a hole in the roof to accommodate the diameter of the 8' extension
sample line (5/8" OD).
3. Install the provided roof flange over the hole.
•
Make sure to use good quality roof sealant for the base of the roof flange
to ensure weather tightness and to prevent any leaks into the shelter
4. Without locking it down, setup the sample line tripod so that its sample line
hole aligns with the hole in the roof.
•
The tripod should be setup at such a height to properly support the
sample line with the inlet on top.
5. Without the inlet installed on the top of the ASC, line up the instrument so
that the opening at the top of the ASC is in-line with the sample line hole/roof
flange on the shelter roof.
6. Slide the 8' sample line extension down through the tripod and the roof
penetration until it meets the opening at the top of the ASC.
•
The sample line should be plumb to prevent any strain on the instrument
and to prevent pneumatic leaks.
•
The sample line should slide into the top of the ASC (about 2") and
bottom out when in completely.
7. Lightly tighten the tripod cord grip and the roof flange cord grip around the
sample line to hold it in place.
8. At the top of the sample line (on the roof), place the provided inlet collar so
that its top is 3" from the top of the sample line.
•
This is for proper clearance from the base of the inlet and to prevent any
instrument flooding if the inlet were to ever get water inside of it.
9. Lock down the collar once it is determined to be at the proper spot 3" from
the top of the sample line.
10. Place the inlet on top of the sample line.
•
Make sure the inlet is secure. i.e. that the collar holding it is not sliding.
•
Proper installation should have the inlet 2-m above the roof.
11. Plug the ASC connector into the proper fitting on the rear panel of the T640.
