INSTALLING OR REPLACING HEAT EXCHANGERS
REMOVING THE HEAT EXCHANGER
1.
Remove the inlet and outlet tubes by loosening the compression fittings. Always use a backup wrench on the fitting
body to ensure no damage to the heat exchanger occurs.
2.
Remove the drain fitting using the same procedure as the inlet/ outlet. Remove the drain fittings from the exchanger.
Use a backup wrench on the lower heat exchanger hex to prevent damage to the exchanger.
REPLACING THE HEAT EXCHANGER
1.
Dry and clean the heat exchanger opening in the heat transfer block using a dry, lint-free cloth (If reusing the heat
exchanger, clean the outside as well.) Dried heat transfer paste can be removed by using a very fine abrasive pad
wrapped around a drill bit.
2. Smear the outer diameter of the heat exchanger with heat transfer paste.
3.
Gently push the heat exchanger into the heat transfer block until the head is fully seated against the insulation on top.
4.
Reinstall the drain fitting. Ensure pipe tape is used on the pipe threads before installation. Use a backup wrench on
the heat exchanger lower hex to prevent damage to the exchanger.
5.
Reconnect the drain, inlet and outlet tubes.
