NSTALLATION
The Model ICOOL should be installed away from heat sources in a well ventilated
area of an instrument rack or enclosure. REMEMBER, the Model ICOOL can only
control to 61
°
F DIFFERENTIAL from ambient temperature. Thus, at an output
temperature control of 39
°
F, the maximum ambient temperature is 100
°
F, above
which cooling control is lost. When this differential is exceeded, the controller will go
full-on, with the cooling capacity floating in relation to the ambient temperature
above 104
°
F. No damage will occur to the cooler; however, the output dew point will
also float in relation to the ambient temperature. The more stable the ambient
temperature environment around the ICOOL, the better the output dew point
stability.
The outlet tubing of all metal or Kynar heat exchangers is 1/4" compression tube
fittings; the user should always use the compression type fittings provided for that
purpose by the factory. The inlet tubing of all metal or Kynar heat exchangers is
3/8”
tube fitting
to mate with most standard 3/8” sample lines.
The condensate drain connection is a Kynar
®
straight
3/8” MNPT x 1/4” barbed tube
fitting. An automatic condensate drain, Model 3KPB-001 Peristaltic Pump, dual
head, is recommended for water removal. This pump uses size 17 tubing.
CAUTION: Do not 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.
