Seasonal start up
Annual start up is a good time to assess motor winding ground resistance. A semi-annual check and recording
the resistance value measured keeps track of insulation deterioration. All new units have a resistance over 100
Mega Ohm between each motor terminal and grounding.
1. Check and tighten all electrical connections.
2. The control circuit must be switched off for the entire time.
3. Replace the cooling tower pump drain plug if it was removed during previous season shutdown.
4. Install the main fuses (if removed).
5. Reconnect water lines and refill the circuit. Purge the condenser and check for leaks.
