9. Piping Size
If it is expected that the secondary air flow velocity will be more than 30 m/s,
install a diffuser in order to keep the flow velocity below 30 m/s.

Straight-run Piping Lengths: Upstream = 10 d or more; Downstream = 15 d or more
(d = pipe diameter)
10. Accessories
Always install a shut-off valve, pressure gauge and bypass lines at both inlet and
outlet.
Ball valves, which will not retain condensate, are recommended for inlet and
outlet shut-off valves. The bypass pipe should be at least ½ of the size of the inlet
(primary side) pipe.
COSPECT has a built-in strainer, however in case an external strainer is installed,
it should be installed ahead of COSPECT and the strainer should be installed
horizontally with the basket at the 3 or 9 o’clock position in order to prevent
condensate accumulation.
