ing, fingers, or tools, causing severe in-

jury to personnel.

Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.

Be sure

the pump and power source have been

properly lubricated, see

LUBRICATION

.

Remove the fill cover assembly (37) and fill the
pump casing with clean liquid. Reinstall the fill
cover and tighten it. Refer to

OPERATION

, Section

C, before putting the pump back into service.

LUBRICATION

Seal Assembly

(Figure 2)

Before starting the pump, remove the vented plug
(9) and fill the seal cavity with approximately 20
ounces (0,6 liters) of SAE No. 30 non-detergent oil,
or to a level just below the tapped vented plug hole.
Clean and reinstall the vented plug. Maintain the oil
at this level.

Bearings

(Figure 2)

The bearing housing was fully lubricated when
shipped from the factory. Check the oil level regu-
larly through the sight gauge (20)and maintain it at
the middle of the gauge. When lubrication is re-

quired, add SAE No. 30 non-detergent oil through
the hole for the air vent (10).

Do not

over-lubricate.

Over-lubrication can cause the bearings to over-
heat, resulting in premature bearing failure.

NOTE

The white reflector in the sight gauge must be posi-
tioned horizontally to provide proper drainage.

Under normal conditions, drain the bearing hous-
ing once each year and refill with approximately 28
ounces (0,8 liter) clean oil. Change the oil more fre-
quently if the pump is operated continuously or in-
stalled in an environment with rapid temperature
change.

Monitor the condition of the bearing lubri-

cant regularly for evidence of rust or mois-

ture condensation. This is especially im-

portant in areas where variable hot and

cold temperatures are common.

For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.

Power Source

Consult the literature supplied with the power
source, or contact your local power source repre-
sentative.
