Equipment Condition:
TWPS in Standby Shutdown with or without draining down as required
Replace a hose that is clamped onto a fitting as follows (see Figure 1):
1. When replacing a clamped-on drain hose, make sure the TWPS is in Standby Shutdown without
Draining Down. Refer to WP 0017.
2. For all clamped-on hoses other than a drain hose, make sure the TWPS is in Standby Shutdown
with Drain-Down. Refer to WP 0017.
3. Turn the screw on the hose clamp to loosen the clamp and pull the clamp back down the hose
from the fitting.
4. Pull or cut the hose off the fitting.
5. Remove the hose from the fitting at the other end in the same manner.
NOTE
When measuring the length of a hose to be replaced, remember to include any
portions of the old hose that you cut off in the total length for the replacement
hose.
The black product tubing must be cut to a length so that, when installed, it does
not drop below the end connection on the 3-way valve.
6. Measure the hose length.
7. Cut new hose to length from bulk.
8. Obtain replacement clamps if the existing clamps are rusted, corroded, or need replacement for
any other reason.
9. Slide a clamp over one end of the replacement hose.
10. Push the hose all the way onto its fitting.
