GENERAL
CAUTION: Handle GRTF Teflon® coils with extreme care. Contact with sharp or blunt objects may cause tubes to rupture.
1.Inspect the product for any damage during shipment. Consult factory if any damage is evident.
2.Insure the equipment is correct dimensionally as ordered. Be certain the unit is set up for the proper heat transfer mode (steam or fluid).
3.It is ultimately up to the customer to choose the proper materi- al of construction based upon their knowledge of the chemical composition of the solution being heated/cooled. Chromalox will aid in the selection process, but cannot warrant any prod- uct due to failure by corrosion that is the result of operating conditions beyond our control.
INSTALLATION
1.Care should be used when handling Teflon® products.
2.When installing coils, insure all threaded fittings are held securely in place by a wrench.
3.Use approved sealant material when installing piping.
4.For Teflon® products, make certain line pressure does not exceed 25 PSI or 450˚F. Metal products should not exceed 100 psi.
5.If
MAINTENANCE
1.Check coils periodically for coatings and corrosion buildup. Cleaning of coils is most effectively done chemically. Insure that the chemical agent is compatible with the coil material. A wire brush can be used on metal heat exchangers. Never use wire
brush on Teflon® coils. Follow all safety precautions as recom- mended by the cleaning agent manufacturer, including goggles, gloves, aprons, etc.
