2. Provide openings in water piping for required pressure gages and thermometers. For
thorough mixing and temperature stabilization, wells in the leaving water pipe should
extend inside pipe at least 2 in. (50 mm).
3. Install air vents at all high points in piping to remove air and prevent water hammer.
4. Install pipe hangers where needed. Make sure no weight or stress is placed on waterbox
nozzles or flanges.
5. Water flow direction must be as specified in
Figure 7
,
Figure 8
,
Figure 9
,
Figure 10
and
Figure 11
.
Note: On 2-pass machines, entering water is always the lower of the 2 nozzles. Leaving water
is always the upper nozzle for cooler or condenser.
6. Water flow switches must be of vapor-tight construction and must be installed on top of pipe
in a horizontal run and at least 5 pipe diameters from any bend.
7. Install waterbox vent and drain piping in accordance with individual job data. All
connections are 3/4-in. FPT.
8. Install waterbox drain plugs in the unused waterbox drains and vent openings.
9. Install optional pumpout system or pumpout system and storage tank.
