II Liquid Level Switch

2.4.2 What to Avoid
1. NEVER leave the switch housing cover off of the control
longer than is necessary to make routine inspections.
2. NEVER place a jumper wire across terminals to “cut-out”
the control. If a jumper is necessary for test purposes,
ensure that it is removed before placing the control into
service.
3. NEVER attempt to make adjustments to or replace switches
without reading instructions carefully. When in doubt,
consult the factory or your local representative.
4. NEVER use in systems containing iron particles. The
magnet in the float assembly can attract the particles and
become jammed.
5. NEVER put insulation over the switch housing.
2.4.3 Switch Mechanism Replacement
1. Have the proper replacement switch mechanism on hand.
See Section 2.6.1 on page 14 for replacement parts.
2. Remove housing cover.
3. Remove the four screws in the corners of the switch
mounting bracket and remove switch mechanism and
magnet assembly.
4. Place new mechanism into the housing.
NOTE: Looking into the switch housing with the conduit connection
pointing downward, the correct orientation of the switch mech-
anism is with the green head ground screw on the right hand
side of the enclosure.
5. Once it is properly placed, secure the mechanism into the
housing by replacing the four screws in the corners of the
mounting bracket.
6. By moving the level in the vessel or by moving the float by
hand, ensure that the switch actuates properly.
7. Replace housing cover.
