GROUNDING – Equipment must be grounded in ac-
cordance with Table 250–95 of the National Electrical
Code.
Failure to properly ground the com-
pressor package could result in con-
troller malfunction.
MOTOR LUBRICATION – Long time satisfactory op-
eration of an electric motor depends in large measure
on proper lubrication of the bearings. The following
charts show recommended grease qualities and re-
greasing intervals for ball bearing motors. For addition-
al information refer to the motor manufacturer’s
instructions. The following procedure should be used
in regreasing:
1.
Stop the unit.
2.
Disconnect, tag and lockout the unit from the pow-
er supply.
3.
Remove the relief plug and free hole of hardened
grease.
4.
Wipe lubrication fitting clean and add grease with
a hand–operated grease gun.
5.
Leave the relief plug temporarily off. Reconnect
the unit and run for about 20 minutes to expell the
excess grease.
6.
Stop the unit. Replace the relief plug.
7.
Restart the unit.
Rotating machinery can cause injury
or death. Open main disconnect, tag
and lockout power supply to the start-
er before working on the electric mo-
tor.
