5.2.1 Remove and replace the inlet screen
The inlet screen is supplied ed on CF pumps only. Remove the inlet screen only if
there is no possibility that debris can fall into the pump. If the inlet screen is removed,
the pumping speed will increase by up to 20%.
CAUTION
The rot
or blades on the pump are very sharp. The absence or removal of inlet screens
or strainers exposes the risk of injury from sharp edges or moving parts.
Care must be taken to avoid foreign objects from entering the pump during inst
allaon.
The pump is supplied with either an integral mesh centring O-ring seal or a pre-ed
mesh screen. This must be ed during installaon.
In the unlikely event of pump fracture, it is possible that the inlet screen may not trap all
of the debris within the pump. Ensure that the system can contain any debris that may
escape from the pump.
The screen protects the pump from contaminaon. Do not remove the inlet screen unl
the pump is about to be mounted onto the system.
1. To remove the inlet screen from a pump with CF inlet ange, use a ben
t wire hook
or small screwdriver to carefully lever the inlet screen out from the inlet ange.
