Use only 10mm (3/8”) copper tube when connecting the discharge stub to the condensate pump.
The discharge line from the pump should rise no more than 6 meters vertically and no more than 8
metres in total length before being interrupted with a swan neck air break and tundish.

Condensate and Humidier
All drain trays are tted with their own trap assembly.
Condensate drain may be run to waste via ordinary plastic waste pipe.
Humidier drain may be run to waste via pipe suitable for liquid temperatures of 100°C.
All drain pipework operating under gravity should be sloped away from the equipment and the gradient should be made
as steep as possible.
Suitable rodding positions should be incorporated particularly if the run is long.
Water Conductivity
As standard the humidier is tted with the standard conductivity cylinder which covers the majority of water supplies.
Low and High conductivity options can be specied at order.
Safe Operation of Humidier
To protect the humidier bottle from dangerous pressures in event of the steam supply pipe becoming blocked, a tundish
is installed between the water inlet solenoid and the cylinder to act as a reservoir and to feed water to the humidier inlet
manifold as required.
An overow weir is incorporated in the common ll/drain tundish. Any pressure build up in the
cylinder would be allowed to vent through the tundish to atmosphere. It is MOST IMPORTANT that
the steam distribution pipe is not damaged or kinked at any time to avoid the risk of unacceptably
high pressure building up in the electrode bottle.
