OPERATIONS TO BE PERFORMED BEFORE UTILISING
All joinable regulators include one G3/8 or G1/2 port on one side for connection of
the regulated outlet and a G1/8 port on the opposite side for the optional
connection of a pressure gauge (port concealed by cover plate trim)
●●
●●
●
Installation with pressure gauge
- Remove regulators with G1/8 port and trim on front
- Remove the trim
- Manually install the pressure gauge
●●
●●
●
Installation without pressure gauge
- Remove the trim
- Seal the plug supplied on G1/8 port with a suitable product.
- Reinstall the trim
- Choce of installation orientation with regulated outlet on front or side
●●
●●
●
Assembly / joinable
Easily joined to all Modulair 112 range devices by means of a joining system
accessible from the front
●●
●●
●
Connection of regulated outlet ports
- Orientate the regulators as per the above mounting option, then proceed to
connect the regulated output ports
●●
●●
●
Connection to pressure supply
- Supply connection at left-hand and/or right-hand side
-
Installation recommendation: A single pressure inlet can supply a set of five
regulators. If there are more than five, supply from both ends is necessary.
- Possibility of having supplies with two different pressures, by placing a blanking
plate at the appropriate point
