Attach Water Supply to Pumpout Condenser
Obtain water from the source (usually city water) specified in the job data. Attach water
supply and return lines to 1/2-in. FPT connections at end of pumpout condenser. Shut-off valves
or other controls are field supplied. Water must be clean and noncorrosive. Pipe the leaving
water to an open sight drain and provide for water drainage during extended shutdown. See
Figure 13
.
Install Vent Piping to Relief Devices
The 19FA chiller is factory equipped with relief devices on the cooler and storage vessels.
Refer to
Figure 2
and
Table 2
for size and location of relief devices. Vent relief devices to the
outdoors in accordance with ASHRAE 15, latest edition, and all other applicable codes. To
ensure relief valve serviceability of the storage vessel and as required in ASHRAE 15, latest
edition, 3-way valves and redundant relief valves are installed. See
Figure 14
. Only one half of
the total number of relief valves listed in
Table 2
are in service at any time.
