Humidifier (Optional Extra)
Water Conductivity &
Cylinder Type Conductivity is a measure of the ability of water to pass an electric current, measured in
micro Siemens / centimetre (
mS/cm). 3 different cylinders are available which correspond
to the supply water conductivity.
Matching the correct cylinder type with the conductivity of the supply water ensures
optimum performance and increases the life span of the cylinder.
1 Low Conductivity (Soft Water) 100 to 350 mS/cm
2 Standard Conductivity (Moderate/Hard Water) 350 to 750 mS/cm
3 High Conductivity (Very Hard Water) 750 to 1250 mS/cm
As standard the humidifier is fitted with the standard conductivity cylinder which covers
the majority of water supplies. Where the water conductivity is known, this should be
specified at the time of order.
Humidifier Pre Start
Checks 1 Ensure a water supply is available to the humidifier at the correct pressure
and quality.
IMPORTANT 2 Ensure security and tightness of connections.
3 Ensure the drain line is connected and that water flows away freely. This can be
carried out by first checking free draining from the tundish, prior to filling then
draining the cylinder.
4 Ensure that the steam distribution pipe is connected securely at both the distribution
and cylinder ends and is not kinked or damaged.
Commissioning 1 Open the (customer supplied) water supply valve adjacent to the unit.
2 With the bottle in operation and the feed solenoid valve (Yellow) activated, ensure
the water is feeding via the tundish to the humidifier. Watch the initial start-up
procedure commence. Fit clamp on ammeter onto 1 of the wires feeding the
electrodes and observe the current.
3 The current can also be viewed through the microprocessor display keypad.
Compare the clamp on ammeter with the display reading to ensure they concur (0.5
amp tolerance).
4 The steam output can be reduced by changing the output demand through the
microprocessor display menu.
IMPORTANT 5 Record humidifier bottle type, supply water conductivity and supply water
pressure on the commissioning sheet provided.
Condensate Pump
Priming Prior to unit start up the condensate pump reservoir should be slowly filled with clean tap
water, until the pump activates. Keep filling the pump and check that the discharge is
properly pumping through. This will prime the system for normal operation.
