DANGER

Use an approved level controller with

a current rating that matches the

4.1 Pipe connection

Threaded steel or rigid plastic pipes can be

screwed directly into the 1.5" NPT outlet port.

For permanent installation, we recommend that

you fit a union, a non-return valve and an

isolating valve in the outlet pipe.

Other recommendations:

•

For portable or temporary installations, a

plastic outlet pipe can be used in conjunction

with a suitable, screwed connection or a

hose coupling.

•

Threads must be sealed using Teflon

Do not install the pump hanging from

the outlet pipe or hose.

Do not lift the pump by its power

cable. Lower and lift it by means of a

wire or chain fastened to the pump

handle.

4.2 Minimum space

When the pump is installed in a permanent

installation with a float switch, and the cable

length is set to the minimum length of at least

4 in. (100 mm), the minimum dimensions of the

sump pit, basin or tank must be as shown in

fig. 2.

In addition, the sump pit, basin or tank must be

sized according to the relation between the

water flow to the sump pit, basin or tank and the

pump performance.

tape.

When the pipe or hose has been connected,

place the pump in its operating position.

Position the pump so that the inlet strainer will

not be blocked by sludge, mud or similar

materials.

In a permanent installation, the installation site

must be cleared of sludge, pebbles, etc. before

the pump is installed.

We recommend that you place the pump on a

solid base. See fig. 4.
