5. As an aid to servicing, thermometers and pressure
gauges should be installed in each of the inlet and
outlet water lines. One connection piont (plugged)
is provided in each cooler nozzle. Thermometers and
gauges are not furnished with the unit and are to be
furnished by other suppliers.
6. The chilled liquid lines that are exposed to outdoor
ambients should be wrapped with a supplemental
heater cable and insulated to protect against freeze-
up during low ambient periods, and to prevent for-
mation of condensation on lines in warm humid cli-
mates.
7. A chilled water flow switch, (either by YORK or oth-
ers)
MUST
be installed in the leaving water piping
of
EACH
cooler. There should be a straight horizon-
tal run of at least 5 diameters on each side of the
switch. Adjust the flow switch paddle to the size of
pipe in which it is to be installed. (See manufactuers
instructions furnished with switch). The switches are
to be wired to terminals in the respective control
panel as shown in the WIRING DIAGRAM.
WARNING: Flow switch must not be used to stop and
start chiller. It is intended only as a safety
switch.
