3.3 Installation
3.3.1
The unit should be fitted in horizontal pipework with the bowl vertically downwards.
3.3.2
Adequate space should be provided around the unit to allow easy access for routine
servicing requirements (see Figures 2 and 3 for withdrawal distances).
3.3.3
Connect the unit so that the airflow is in the direction indicated by the arrow on the
body.
3.3.4
The unit should be installed as close as possible to the equipment it is serving.
3.3.5
A pressure gauge can be connected to one of the " ports. The gauge should be
selected to cover the maximum pressure range of the main control spring. The gauge
will indicate the downstream or controlled pressure.
3.3.6
Ensure that the control spring range selected for the regulator fully meets the pressure
requirements of the system.
3.3.7
Do not overload the filter cartridge (see Section 4 - Operating principals) or there will be
a reduction in its efficiency and / or life. On heavily contaminated systems, it is advisable
to fit a conventional pneumatic filter (Monnier International or Miniature) immediately
in front of the unit for maximum efficiency and life cycle.
3.3.8
The polycarbonate bowl may be fitted with a bowl guard.
