Section 2.2: Component Failure by Conditions
CONDITION COMPONENT FAILURE
If steam is coming out of the drain line while at
idle. ** Note: Some water vapor/condensate is
normal.
Confirm V3 is in closed position. Remove brass
pipe plug from reducing tee directly above the V3
diaphragm valve. Slowly open the steam supply
valve to see if steam flows past the V3 seat seal
into the reducing tee. If steam is present, V3 and
the valve body seal need to be repaired or re
-
placed (
Section 4.3
). If steam is not present the
TV/HAT 155 needs to be replaced. (
Section 4.7
)
If the outlet temperature remains above the
normal range for long periods of time without
fluctuation in the outlet temperature.
Follow Section 4.1 to check or replace V1 mixing
valve. Check V4 control valve and replace if not
functioning correctly.
If the outlet temperature fluctuates, rising above
dropping below the normal range.
Follow Section 4.1 to check and/or adjust V1
mixing valve. If it cannot be adjusted, replace V1.
If the eyewash is running in the normal range,
but the shower runs below the normal range.
The V2 Capillary Valve needs to be adjusted.
(
See Section 4.2
)
If the eyewash runs above the normal range, but
the shower runs in the normal range.
**Note: Steam will probably be coming out of the
drain line while running the eyewash.
The V2 Capillary Valve needs to be adjusted
(
See Section 4.2
). If the valve cannot be ad
-
justed correctly a replacement V2 Capillary is
required.
If there is a constant flow of warm water flowing
through drain line.
V-6 has failed open. (
See Section 4.6
)
If there is an momentary temperature spike over
100 °F when flow begins.
V-6 has failed closed. (
See Section 4.6
)
Cold
Water
Only
If the V3 does not open allowing
steam to pass to the heat exchanger.
**Note: Check to see if the V3 indica
-
tor does not move.
Inspect V3 to make sure it is not jammed (
See
Section 4.3
). Remove the V4 Control valve for
testing. (
See section 4.4
)
V3 opens approximately .300in., V1
is properly adjusted (
See Section
4.1
), V2 is open
Verify that steam is present at the Heater.
Remove the Y-strainer cap and check the screen
for debris. If the Heater is still not producing tepid
water the heat exchanger may be clogged with
minerals. The Heater can be flushed in place or
removed and flushed with the proper equipment.
If the proper equipment is not available the unit
can be returned to the factory for flushing and
recalibration.
V5 does not allow water to pass
through V1
Verify that the hot water line above V5 is hot
and hot side inlet to V1 is cold during operation.
Either the actuator has failed or cold water is
blocked.
