Unit Preparation

Do not leave the unit unattended while

p ressurized. A cold water fill could

expand and cause excessive pre s s u re ,

resulting in severe personal injury, death

or substantial property damage.

7. Ensure constant gauge pressure has been

maintained throughout the 10 minute test.

Check for leaks at all fitting joints. Repair

if found.

Leaks must be re p a i red immediately

when detected. Failure to repair leaks

can damage the unit, resulting in sub-

stantial property damage.

8. Check continuity using a voltmeter across

the terminals of the LWCO device. The

contacts on the LWCO should be closed.

See item 6 in Figure 40 page 64 for loca-

tion of the LWCO.

Completion of Hydrostatic Test and Draining

1. Disconnect the fill hose from the fresh

water source and direct the hose to a suit-

able place of drainage.

2. Open the primary drain valve and complete-

ly drain the unit. To aid in draining open the

s h u t - o f f valve on the primary supply.

3. Remove the hose from the primary drain

valve when draining is complete.

4. Remove the plugs, nipple, shut-off valve

and any other piping unless they will

remain for use in the system piping.
