INITIAL TEST PROCEDURE - MODEL 24-CGA-10

Before starting this procedure, review the Introduction and perform the General
Preparations.

WARNING

Death, severe electrical shock or equipment damage
can result from touching any component inside the unit
when the main disconnect switch is in the on position.
Use extreme caution during testing with an access
cover removed.

Set Up The Initial Test Conditions.

1. Turn off the control panel ON/OFF power switch.

2. Turn off the Main Disconnect Switch.

3. Make sure water is supplied to the unit and is on.

4. Make sure gas is supplied to the unit and is on.

5. Remove the right side and front access panels. The float assembly, relays and

contractors should be clearly visible.

PHASE 1 TESTING

This phase of testing pertains to components associated with the water fill, drain, and
blowdown functions. The panel ON/OFF switch is OFF throughout this phase. The
TIMED/MANUAL switch and TIMER settings are not significant while the
ON/OFF switch is in the OFF position.

IT:1-1. Is there water standing in the float cylinder?

NOTE:

The drain valve is normally open. With power off at both the ON/OFF

switch and Main Disconnect, the drain valve is open. The steam generator and float
cylinder is empty.

Water in the float cylinder indicates that during the last shutdown sequence, water
did not drain from the steam generator.

1. Check for blockage in the plumbing between the float cylinder and the steam

generator.

2. Check the drain solenoid valve and adjoining plumbing for blockage.

3. Check the drain line and air gap between the line and floor drain.

4. If the plumbing, drain lines, and drain valve are not blocked, refer to component

test

CT:1 and test the drain (3-Way) solenoid valve.
