Air Cooling Connection Kit
Compressed Air Cooling Kit (60038416), installation
The optional air cooling kit for high ambient temperatures over 45 °C includes quick-connect fittings
that are placed in the two plugged holes. Tubing is also supplied, along with an air filter set with
regulator to remove water and oil from the compressed air supply.
Adjust the air supply volume until the temperature is below this value
This kit includes three Air Fittings, a 30 cm (11.8 inch) piece of air tubing, and 20 m (65 feet) of extra
tubing.
Preparation for Installation:
1.
Loosen the tri clamp and pull out the round plate with the
two blind plugs.
2.
Remove the two blind plugs and mount the air fittings
instead.
3.
Mount the third air fitting on the inside of the plate. Use the
hole closest to the bottom of the cabinet. This is now the air
input.
4.
Some of the first kits included a Silencer (Ceramic cylinder
on a short brass tube) for the exhaust. This must NOT be
mounted; it may cause a too high pressure inside the box.
Mounting the air tubing:
5.
Cut the tube to length with a clean cut.
6.
Push the end of the tube into the fitting until it makes a
tight seal.
7.
To remove the tube, press down the collar of the fitting
while gently pulling the tube.
Connecting the units:
8.
Mount the 30 cm tube in the air input fitting on the inside of the round plate. Lead it into the
instrument, under the Mounting Tray so that the outlet is close to the opposite wall. If
needed, adjust the length of the tube.
9.
Mount the plate on the instrument again, and tighten the Tri-clamp.
10.
Mount a suitable length of tubing to the air out (exhaust) air fitting on the Analyzer PRO. Lead
the tube to terminate at a point where the exhaust flow of air is not objectionable to nearby
personnel.
11.
ATEX rated areas may require termination of the exhaust tube to another room or outside.
Check with the customer’s Safety personnel, or the on-site ATEX-responsible person.
12.
Mount a tube from the regulator to the air input on the Analyzer PRO.
