2.5 Maintenance
2.5.1 Keep Control Clean
Periodic inspections are a necessary means to keep your
level control in good working order. This control is a safety
device to protect the valuable equipment it serves.
If the process liquid is clean (no solids or deposits), the
MLI should require minimum maintenance. If the process
liquid is dirty (solids and deposits), it is recommended the
external cage be isolated from the process and flushed peri-
odically. For complete cleaning, drain the unit, remove the
bottom flange and float, inspect cage and float for build-
up and clean if required.
2.4.2 Agency Specifications – Explosion Proof Installation
Factory Sealed:
This product has been approved by Factory Mutual Research
(FM) and Canadian Standards Association (CSA) as a Factory
Sealed device.
NOTE: Factory Sealed: No Explosion Proof conduit fitting (EY seal) is
required within 18" of the transmitter. However, an Explosion
Proof conduit fitting (EY seal) is required between the haz-
ardous and safe areas.
Caution: Grounding (+) will cause faulty operation, but will not
cause permanent damage.
Caution: Do not rotate the Jupiter electronics enclosure or any
threaded fittings. Rotating the electronics enclosure will
void warranty and could cause damage to sensor cables.
