Any earthing straps disconnected to carry out work on the pump unit must be replaced before
pump is restarted.
Maple pumps: Fitting or removing the stroke counter requires handling magnets
with intense field strengths - not to be carried out by those wearing a pacemaker or
similar device. Unrestrained magnets may move suddenly resulting in impact
damage or attract debris.
Use appropriate PPE when handling fluids such as grease.
The stroke counter unit must not be exposed to long term sunlight or other sources of ultra-
violet radiation to reduce risk of damage to plastic parts.
Turn off switching isolation barrier power before connecting or disconnecting cable plug from
sensor.
PRODUCT SPECIFIC WARNINGS
Maximum operating pressure (Bar): 7
8.2
The sensor must only be connected via the supplied cable to a suitable switching
isolation barrier unit located outside the hazardous zone designed to operate
NAMUR type sensors.
The sensor must not be subjected to any applied mechanical forces (examples: impacts, cable
pulling).
Cable plug and sensor connector attach in one angular location only - do not force: align
locating lug in sensor with notch in cable plug before pushing together and tightening threaded
collar to secure.
Some stroke counter components are plastic - do not use aggressive chemicals to clean. Use a
cloth damped with water for wiping unit clean if required.
Ensure pump is stopped and isolated from air and fluid systems before dismantling any part of
the pump.
During operation some surfaces of the pump may become very cold - be aware of a risk of skin
burn if dismantling pump parts immediately after shutting down.
Route sensor cable away from power cables and in a manner to avoid it becoming a trip
hazard.
Do not coil or heap excess cable inside the hazardous zone.
The stroke counter does not contain serviceable parts - if output from sensor fails, the complete
unit containing the sensor must be replaced.
