8 / INSTALL DRAIN PORT
You need to position the port so that you have enough room to
manoeuvre to drain the coolant into a container. The container should
be placed outside of your case in case of spills.4 / INSTALL FILL PORT
Insert the fill port thread into the hole and ensure the top cap sits flush
with your case. Then secure the locking ring from the underside and
ensure it’s firmly secured.
5 / CONNECT FITTING AND TUBING
Both the fill port’s ends have G1/4in threads, so you can install a bung in
the top and a fitting underneath. Install the latter, and then run a length of
tubing down to the top port on your reservoir. You can now fill your loop.
7 / USE ROTARY ADAPTOR
If you’ll be connecting the drain port straight to a G1/4 port on another
component, you’ll need a rotary adaptor with male threads on either
end. This adaptor can connect the two components together, but
allows you to rotate the drain port, so the lever sits at the top.6 / LOCATE SUITABLE DRAIN PORT
Drain ports need to be low down and ideally near large components, so
they can drain as much coolant as possible. Reservoirs often hold a lot
of coolant, so they can be useful locations for drain ports, but you can
also install a port along a length of tubing using a three-way splitter.
9 / CONSIDER SEPARATE TUBE RUNOFF
If the port’s location makes draining into a container difficult, you can
add an additional length of tubing to make draining easier. You can
either attach a length of tube temporarily to the drain port, or even
create a swing-out port using a length of rigid tubing and a 90-degree
rotary joint, as we’ve done here.
