4. Connect power leads to main disconnect (refer to
Figure 14, p. 29 for power connection location). Wiring
should
match power requirements on the assembly
nameplate in accordance with local codes (refer to
Table 10).

5. Wire the customer remote contact connection to the
pump control relay in the drive enclosure. This
connection gives the drive control of the cooling
assembly (refer to “Standard Control Wiring,” p. 38,
for AFDK term
ination location and requirements).
6. Fill the reservoir tank through the
manual fill port to a
level between the two black indicators on the sight
glass. The process fluid in the primary cooling loop
should be distilled water treated with an inhibitor
solution. The secondary water loop may be filled with
condenser water. For a more detailed description of
process fluids including addition of inhibitor solution,
refer to “Corrosion,” p. 33.
7. Turn the control switch to “on” position. The
ci
rculating pump should begin rotation.
8. Continue circulating pump for
five minutes to
allow air
in system to be vented.
9. Ensure all process fluid lines and shutoff valves are
open and the
system is able to flow freely. Re-check the
fluid level in the system before continuing with the
startup and note start-up pressure on fluid ports as a
baseline.
