Service and Checkout
1. Never use oil on any part of the relay coil or contacts.
2. Keep the cover on the relay during normal operation
and remove only for service and checkout.
3. Relay contacts require no cleaning; contacts close
with a wiping action and are self-cleaning. They may turn
black after being in service for some time; however, this
discoloration does not prevent proper operation.
4. After installation is complete, operate system through
at least one cycle from the controller to make certain the
relay controls the equipment as intended.
