The Mikrofill 3 is connected to the system by way of the 15mm outlet isolation valve. The pipework from the unit
should be made in 15mm copper or similarly approved plastic pipework. A suitable sized expansion vessel
should be incorporated into the system at this point (please refer to the typical installation diagram on
page

for more information).
Please contact our technical department on

if you require any assistance regarding vessel
sizing.
The final connection into the system should be sized accordingly, recommendations are shown below:
• Vessel size up to
½”
• Vessel size up to
¾”
• Vessel size up to
1”
For vessel sizes in excess of 1000L capacity please contact our technical department.

the unit is supplied fitted with a ¾” BSP tundish, which must be connected to a suitable drain.
