INSTALLATION

 

Step

 

Five

 

The

 

basic

 

operating

 

principle

 

of

 

the

 

sump

 

float

 

is

 

very

 

simple.

   

As

 

fluid

 

level

 

rises

 

the

 

float

 

will

 

also

 

rise,

 

resulting

 

in

 

a

 

tilt

 

of

 

the

 

micro

switch

 

located

 

inside

 

the

 

housing.

   

This

 

tilt

 

will

 

generate

 

a

 

signal

 

that

 

can

 

be

 

used

 

to

 

actuate

 

a

 

motor

 

or

 

signal

 

an

 

indicator

 

alarm.

  

To

 

ensure

 

the

 

proper

 

function

 

of

 

the

 

sump

 

float,

 

it

 

is

 

necessary

 

to

 

secure

 

the

 

electric

 

cable

 

inside

 

the

 

tank

 

or

 

well.

  

The

 

length

 

of

 

the

 

cable

 

measured

 

between

 

the

 

fixture

 

point

 

(see

 

below)

 

and

 

the

 

body

 

of

 

the

 

float

 

determines

 

the

 

total

 

extension

 

of

 

the

 

float.

  

This

 

results

 

in

 

the

 

distance

 

between

 

the

 

pump

 

stopping

 

and

 

starting

 

level.

  

This

 

distance

 

should

 

be

 

no

 

less

 

than

 

6

 

in

 

(15

 

cm).

  

It

 

is

 

essential

 

to

 

ensure

 

that

 

there

 

are

 

no

 

obstructions

 

in

 

the

 

sump

 

floats

 

operational

 

area

 

before

 

operation.

   

 

Warning:

   

During

 

operation,

 

adjustments

 

to

 

the

 

sump

 

float

 

cable

 

must

 

not

 

be

 

made

 

under

 

any

 

circumstances

 

due

 

to

 

the

 

fact

 

that

 

any

 

unwanted

 

cable

 

connections

 

made

 

while

 

the

 

sump

 

float

 

is

 

immersed

 

in

 

water

 

can

 

lead

 

to

 

electric

 

shock.

   

There

 

are

 

two

 

installation

 

options

 

for

 

this

 

sump

 

float.

   

One

 

method

 

is

 

to

 

fix

 

the

 

cable

 

of

 

the

 

float

 

to

 

the

 

reservoir

 

or

 

container

 

with

 

the

 

use

 

of

 

a

 

small

 

clamp.

  

Another

 

technique

 

would

 

be

 

to

 

attach

 

the

 

LV49

7000

 

counter

 

weight

 

to

 

the

 

float’s

 

cable

 

a

 

desired

 

distance

 

between

 

the

 

highest

 

and

 

lowest

 

level

 

desired.

   

 

Note:

 

 

With

 

the

 

use

 

of

 

the

 

counterweight,

 

the

 

length

 

of

 

cable

 

between

 

the

 

float

 

and

 

fixed

 

point

 

(starting

 

and

 

stopping

 

indication)

 

can

 

be

 

freely

 

adjusted.

 

 

Note:

 

The

 

LV42

 

series

 

is

 

self

 

counterweighted

 

and

 

can

 

be

 

used

 

without

 

the

 

need

 

of

 

additional

 

counterweight,

 

clamp,

 

or

 

bracket.

  

The

 

previous

 

are

 

means

 

to

 

simplify

 

installation

 

and

 

aid

 

in

 

organizing

 

the

 

use

 

of

 

multiple

 

float

 

switches.

INSTALLATION

 

OF

 

COUNTERWEIGHT

 

For

 

correct

 

counterweight

 

installation,

 

refer

 

to

 

the

 

following

 

procedure

 

as

 

well

 

as

 

the

 

illustration.

 

1.

 

Insert

 

the

 

cable

 

into

 

the

 

counterweight,

 

turning

 

it.

   

This

 

will

 

result

 

in

 

the

 

detachment

 

of

 

the

 

plastic

 

ring

 

inserted

 

in

 

the

 

mouth

 

(if

 

necessary

 

use

 

a

 

screwdriver

 

to

 

aid

 

in

 

the

 

detachment

 

of

 

the

 

ring).

   

Place

 

the

 

ring

 

at

 

the

 

point

 

on

 

the

 

cable

 

where

 

the

 

counterweight

 

is

 

to

 

be

 

attached.

 

2.

 

Attach

 

the

 

counterweight

 

on

 

the

 

ring

 

by

 

turning

 

it

 

and

 

using

 

moderate

 

pressure.

  

(Counterweight

 

sold

 

separately).
