NSTALLATION
The Model M225 should be installed away from heat sources in a well ventilated
area of an instrument rack or enclosure. The more stable the ambient temperature
environment around the Model M225, the better the output dew point stability.
Sample tubing connections to the Model M225 depend on the heat exchanger
material of construction. A cooler with a stainless steel heat exchanger uses a
stainless steel inlet fitting. The outlet is Kynar
®
standard compression type tube
fitting with Teflon
®
ferrules. A PVDF (Kynar
®
) heat exchanger uses Kynar
®
standard
compression type tube fittings with Teflon
®
ferrules. Perma Pure cannot warrantee
against damage to the Peltier element or heat exchanger if our supplied Kynar
®
tube
fittings are not used.
The inlet and outlet tubing for all metal or Kynar heat exchangers is 1/4" NPT; the
user should always use the compression type fittings provided for that purpose by
the factory. The inlet of the Channel 1 heat exchanger uses a 3/8” tube x ¼” MNPT
fitting to mate with most standard 3/8” sample lines.
The condensate drain connection is a Kynar
®
elbow (or straight), 3/8” MNPT x 1/4”
barbed tube fitting. An automatic condensate drain, Perma Pure Model 3KPB-003
Peristaltic Pump, dual head, is recommended for water removal. This pump uses
size 17 tubing.
CAUTION: Do no reduce the size of the condensate tubing since doing so restricts
water flow resulting in water slip (moisture carryover) in the sample.
CAUTION: If using a stainless steel sample line, place 2 inches of Teflon
®
tubing in
between the exchanger inlet fitting and the heated line. This prevents the sample
cooler from heat sinking the incoming heated line, which adds undue load to the
cooler.
