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 (72) 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
Bearings
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauge (29) 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 (18). Do not over‐lubricate. Over‐lu­
brication can cause the bearings to over‐heat, re­
sulting in premature bearing failure.
Under normal conditions, drain the pedestal once
each year and refill with approximately 5 ounces
(148 ml) of clean oil to the middle of the sight
gauge. Change the oil more frequently if the pump
is operated continuously or installed in an environ­
ment 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.
Seal Assembly
Fill the bottle oiler (12) with SAE No. 30 non‐deterg­
ent oil. Check the oil level regularly and keep the
bottle oiler full.
Power Source
Consult the literature supplied with the power
source, or contact your local power source repre­
sentative.
