Pumping Cabinet Control Power Checks
There will be 3 phase power brought into the control power cabinet and
jumpered to the pumping control cabinet. This determines the direction of
rotation of the pumps. There will be arrows on the pump showing the proper
direction of rotation, and it can be visually verified by looking at the non-drive
end shaft. Manually activate the pump control relays and verify the rotation.
Manually activate the fan control relays and ensure each of the fans on the heat
exchanger is rotating. Also ensure that the fans have been wired to the correct
relays (as specified by factory).
