5.4.2.2 Connecting BUM64F to coolant circulation
The BUM64F unit has a pre-mounted heatsink at its back. The topmost and the lowest
threaded hole (G1/8") in the heatsink are destined for the intake and outlet of a coolant
circulation system. For the connection to the customer side of the coolant circulation use
connectors with an outside thread G1/8". Onto these connectors the customers hoses for
intake and outlet can be fitted.
The BUM64F is mounted in a switching cabinet. The heatsink connections are then situ-
ated on the back side of the unit.
Mounting the heatsink connections:
1 supply suitable connectors (material: brass, G1/8“ outside thread)
2 clean the threaded holes and connectors
3 apply silicone sealant, e.g. Loctite 5331 onto a least one (clean!) thread winding.
The silicone sealant prevents either corrosion between the different construction ma-
terials and improves also the security/tightness.
4 turn the connectors by hand into the threaded holes of the heatsink and tighten them
with the maximum admissible torque.
5 connect the intake with one of the connectors.
6 connect the outlet with the other connector.
7 check the tightness of the coolant circulation.
8 perform a leak test with the required pressure (12 bar).
CAUTION
The following may occur , if you do not observe this caution information:
m property damage.
The hazard is: damage of the connectors thread.
do not exceed the maximum torque (6 Nm) when you tighten the connectors.
NOTE
You can choose any direction of flow.
