SERVICE AND CHECKOUT<br />
M3824A<br />
1. Never use oil on any part of the relay coil or contacts.<br />
2. Keep the cover on the relay during normal operation<br />
and remove only for service and checkout.<br />
3. Relay contacts require no cleaning; they are<br />
arranged so they close with a wiping action and are<br />
self-cleaning. The contacts may turn black after<br />
being in service for some time; this discoloration<br />
does not prevent proper operation.<br />
4. After installation is <strong>com</strong>plete, operate system<br />
through at least one cycle from the controller to<br />
make certain the relay controls the equipment as<br />
intended.<br />
