Xylem Heat Exchanger 08036-SSCF-C

Ensure all pressure is off equipment and the unit is drained before opening heads

Inspect all tubes for erosion, corrosion, or foreign material

Inspect all anodes for excessive corrosion or scale insulation

Scrape anodes to a bright surface if necessary

Inspect filters to prevent foreign matter from entering the exchanger

Ensure not to blow out heat exchangers with air when operating fluids are flammable or hazardous

Select cleaning method for heat exchangers

Inspect the anodes for scale or surface coatings

Clean the anodes if scale or coatings are present

Check if pipe plugs are used instead of anodes

Verify the material of the pipe plugs is softer than the base part

Renewable anodes or pipe plugs used

Ensure the heat exchanger is operating within the design pressure and temperature on the nameplate.

Shut off the flow of hot medium first.

If circulation of cooling medium is stopped, ensure circulation of hot medium is also stopped by by-passing or other methods.

Verify equipment is not operated under conditions in excess of those specified on the nameplate.

Drain all fluids to eliminate the possibility of freezing and corrosion.

Drain condensate from steam heaters and similar apparatus to guard against water hammer when shutting down.

Ensure there is no pulsation of fluids to prevent vibration, strain, and resulting leaks.

Open the vent connections and start to circulate the cold medium only.

Are the passages in the exchanger entirely filled with the cold fluid before closing the vents?

Introduce the hot medium gradually until all passages are filled with liquid, then close vents.

Slowly bring the unit up to temperature.

Was the operation started gradually?

Was hot fluid admitted to the unit gradually and not suddenly when empty or cold?

Was the unit shocked with cold fluid when hot?

Inspect for shipping damage and contamination

Is the heat exchanger placed in immediate service?

Take precautions to prevent rusting or contamination if not in immediate service

Describe preservation methods for interior surfaces during storage

Remove accumulations of dirt, water, ice or snow and wipe dry before indoor storage

Was the unit filled with oil or other preservative?

Open drain plugs to remove accumulated moisture if not filled with preservative

Store under cover in a heated area, if possible
