the operation of the check valve to ensure proper
seating and free movement.
Final Pump Assembly
Secure the pump to the base with the previously re-
moved hardware. Be sure to reinstall any leveling
shims used under the pump mounting feet.
Install the shaft key (29) and secure the pump to
the power source with the previously removed
hardware. Be sure the pump and power source
are securely mounted to the base.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure. Open all the
valves in the suction and discharge lines.
Be sure the pump and power source have been
properly lubricated, see LUBRICATION.
Remove the fill cover assembly (76) and fill the
pump casing with clean liquid. Reinstall the fill cov-
er and tighten it.
Refer to OPERATION, Section C, before putting
the pump back into service.
LUBRICATION
Seal Assembly
Fill the bottle oiler (16) with SAE No. 30 non-deterg-
ent oil while venting the seal cavity at the air vent
(15). Check the oil level regularly and keep the
bottle oiler full.
Bearings
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauge (33) and maintain it at the
middle of the gauge. When lubrication is required,
add SAE No. 30 non-detergent oil through the hole
for the air vent (22). Do not over-lubricate. Over-lu-
brication can cause the bearings to over-heat, re-
sulting 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 pedestal once
each year and refill with clean oil to the middle of
the sight gauge. Change the oil more frequently if
the pump is operated continuously or installed 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.
