Water Wizard Operating Procedure Instructions (Cont.)
10) The Heater installation is now set for operation. No further operation procedure is
necessary unless or until further temperature control adjustments may be required. If so,
repeat Steps 4, 5, 6, 7, and, if necessary, Step 8.
11) To SHUT DOWN the System:
a) Close all stop valves in the Steam inlet and Condensate outlet lines.
b) In this order, close the stop valves in
i. the hot water outlet line,
ii. the recirculation line, if any, and
iii. the cold water inlet line (see Step 11c, which follows).
c) If the system includes an accumulator or stratified storage tank, DO NOT SHUT OFF
THE COLD WATER UNTIL THE HEATER HAS COOLED DOWN. If the system is
allowed to cool while the cold water is shut off, the Heater liner may collapse
because of formation a vacuum in the Heater.
12) For DRAINING THE HEATER, see the instruction included under ROUTINE
MAINTENANCE, Chapter 6, Section 6.1.
13) To START UP again, with the shell filled per Step 1 above, open the stop valves in the
following order:
1) stop valve in the Cold Water inlet line,
2) any stop valve in the recirculation line, if any,
3) stop valve in the Hot Water outlet line, and
4) stop valves in the Steam inlet line and Condensate outlet lines.
14) After each startup, check the temperature control. If necessary, make adjustments per
Steps 4 through 9.
