FOR ENGINEERS
The Aspen Mk 4 Water Sensor Pump
Particularly suitable in refrigeration cabinets.
Description:
The Mk 4 pump has a sensor for level detection, which gives off heat in normal operating
conditions and will feel warm to the touch. It is for this reason that when the unit is first
switched on to allow five minutes for the electronics to stabilise.
To ensure that the detector will operate satisfactorily please abide by the following:
Position of Water Sensor:
Free from direct
draft and the tip should be a minimum of
5mm from the base of the tray or water
container. Ensure that the tip is in free air
and unable to touch the sides. There is also
an ambient sensor which is within the
cable 50mm from the gland of the level
sensor. This can be seen as a disc beneath
the sleeve and should be in free air to
avoid heat conduction.
Water Level:
The detector will trigger when
the water level has reached the first 2 or
3mm of the sensor, this should be taken
into account when positioning the height
of the sensor. Note that as the device
works on heat conductivity it can take up
to 30 seconds for the pump to switch on.
Installation Notes:
This pump is designed to sit level on it's base
and must at all times have adequate space
around it for good ventilation.
Ensure that there are no kinks or trapped parts
in the piping, which must have an inside
diameter of
6mm and an outside diameter of
9mm.
Fix the pipes with cable ties to the pump inlet
and outlet.

Service Guide:
1
Inspect the pump head regularly and change pump head tube every 12 months or more often if
required.
2
To remove pump head, make sure roller assembly is vertical. Remove screws and fit replacement
pipe. The addition of a smear of silicon grease will ease the refitting of the lid and reduce
potential friction noise.
3
The test switch should always be returned to the "NORMAL' position after use.
4
Replacement pump head tubes and other accessories can be obtained from the manufacturers.
Please quote the serial number (to be found on the pump) when ordering spare parts.

Pumping:
Once the level of the water has
dropped below the tip of the sensor the
pump will continue
minutes until the heat of the sensor has
completely dried all the water, this allows
time for the pump to drain the remaining
water.
NOTE:
It is important that the level sensor is
never in a situation where it will be
completely submerged up to the
ambient sensor above the gland. In
such an event the device will cease to
operate.
