5. Assembly - The rubber diaphragm has been removed

For maximum pumping efficiency it is recommended

from the pump at the factory and must be reinstalled

that the discharge line be elevated above the height

on the pump before operation. Remove preservative

capacity.

A. Suction Hose - The hose connected to the inlet

or suction side of the pump should be of the rigid

type (non-collapsible). Hose should be free of

any breaks, cuts, pin holes or have a collapsed

liner. When the pumping application permits,

the suction line should be kept as short as

possible.

B. Discharge Hose -Hose on the outlet or discharge

side of the pump may be of the collapsible type,

but the rigid type is preferrable.

On long

discharge lines, the line should be one size, and

sometimes two sizes larger than the discharge

fitting of the pump, in order to decrease frictional

loss.

9. Movement to new worksite - Disconnect the suction

and discharge hose from the pump. Drain pump body

by removing the pump drain plug, reference, Fig. 7. If

extremely hi-solid content water, mud or mucky water

has been pumped, the pump body should be flushed

out with clean water. The clean-out door may be

removed for this purpose, reference, Fig. 3 and 7.
