CONNECTING THE FURNACE TO A LIQUID COOLANT SUPPLY (NOT
REQUIRED FOR MODEL 17702W)
This furnace has a cooling coil installed on the top panel, this is to allow a cooler top panel working surface
that will prevent a hazard to the user when the furnace is at high temperatures and will also minimise any
distortion to the top panel that may lead to damage caused as a consequence of this. Temperatures in
excess of 700°C require the cooling coil to be used, for temperatures below this value it is optional.
The cooling coil is accessed from the rear panel and this will need to be removed to make any connections
or service of the connections.
The cooling medium can be any number of substances, but in most cases water will suffice. Isotech would
recommend a cooled re-circulation system for environmental reasons, however, a simple connection to a
water tap will produce the same results. Please seek advice from your local environmental agency before
cooling from a tap supply.
The requirement will be up to 2 litres of liquid/minute. Connections require a tube or pipe with 3/8” internal
diameter for both the input and output. The exiting liquid will never rise above 50°C so a simple PVC piping
can be used.
There is no directional flow and the liquid can be flowed in either direction.
