The coolant is piped through the plug via insulated standpipes terminated with quick-release
sealed connectors. Mating right-angled connectors are provided to allow the customer
’s
chilled coolant supply to be linked into the standpipe connectors .
The customer
’s
chilled coolant supply must be below 3 bar pressure. Ensure
there is a free flow of coolant through the cooling plug – do not apply coolant flow until
the outlet pipe-work has been connected and unobstructed.
The Cooling Plug should only be inserted or removed from the dry block at coolant
temperatures above 0  C , to prevent icing problems.
The controller display will provide sub-zero temperature readings when the external probe
and cooling plug are used in tandem.
WARNING!
Do not leave a disconnected cooling plug in a dry block whilst heating.
Pressure may build up inside to cooling plug from previously used coolant and
cause a rupture of boiling fluid.
