THE POTASSIUM HEAT-PIPE FURNACE, MODEL 17706
FINAL PART OF THE COMMISSIONING INSTRUCTIONS
The initial slow temperature ramp is maintained until the temperature reaches 400°C.
Impose a heat-pipe set-point of 420°C and set the over-temperature controller to 450°C. Allow 1 to 2 hours for the
furnace to stabilise and then reduce the over-temperature cut-out setting until the relay trips, thus switching off the
furnace.
Allow the furnace to cool and isolate it from the electricity supply.
At the rear are two water connections; these should be connected to a controllable supply and a flow of 1 to 2 litres
of water per minute established - this prevents the top of the cabinet being over-heated at high furnace
temperatures. Run the water for 1 hour to check the furnace for absence of leaks (the floor underneath the cabinet
should be inspected).
The 17706 furnace is now ready for use.
