ANNUAL INSPECTION

1.Flush tank as follows

a.Shut off power supply.

b.Close valve on hot water outlet piping.

c.Open valve on drain piping.

d.Cold water inlet line pressure will be strong enough to flush sediment from the bottom of the tank out through the drain. Let water run for 3-4 minutes.

e.Close drain valve.

f.Open hot water valve.

g.Turn power supply ON.

2.Units subject to exterior fouling or scaling should be cleaned periodically. A marked increase in pressure drop and/or reduction in performance usually indicates cleaning is necessary.

3.To clean the outside of the tubes, remove the heating coil and use either of the following methods.

a.Spray heating coil with water hose.

b.Consult with manufacturers of cleaning compounds and chemicals. They will check the nature of the deposit, recommend the right cleaning compound, and in many cases provide equipment and personnel for a complete cleaning job.

4.Do not tighten bolts until gasket is properly seated.

5.When tightening bolts in the element head, tighten the bolts in a criss-cross pattern. This will evenly distribute pressure around the flange, and help prevent warping.
