BOWMAN EC120 - Connecting the Cooler

When tting the cooler into the pipe work, care must be taken to ensure that
no debris has been introduced into the primary or secondary circuits.
Unsupported lengths of pipework should be avoided so as not to subject the
cooler to excessive loads.
Water side pipework diameter should not reduce to less than the connection
size within a distance of 1m from the cooler.
Measures should be taken to isolate the cooler from excessive vibration. Water
pipe connections are parallel thread. Taper pipe ttings are not recommended
as they can split the end cover if over tightened.
The charge air inlet and outlet are designed to have hose connections using
hose clamps apart from the PK and RK cooler sizes which have ange
connection faces.
Please ensure that the connection ow area is maintained into the cooler and
avoid tight bends to prevent excessive pressure loss.
