5.5.4 Water detection
Water detection tape
•
The water detection tape will be delivered connected to the unit's controller. The
tape will be collected together and should be unwound once the unit is in it's final
position (see Fig. 5-13).
Fig. 5-13
•
The sensor tape should be routed on the floor where it is likely to come into contact
with any leaking water.
•
If possible, run the tape around the perimeter of the unit around the base stand feet
(if fitted).
•
The water sensor needs to be fitted to the floor in such a way that it maintains a
contact with the surface at all times but will not come into contact with any vibrating
parts that could cause damage to the sensor. A quick curing, non-conductive epoxy
resin or silicone sealant is an effective way to keep the water sensor in its correct
location.

Water detection spot
sensors
•
Spot sensors are also available for water detection.
•
These should also be installed in the under unit drip tray (if included).
•
Distribute the sensors evenly to help ensure all areas under the unit can detect a
water build up.
Important Note!
The water detection tape should be installed prior to commissioning and the end
user should be made aware that, upon contact with water, an alarm is generated by
the controller as an indication of the presence of water. This alarm is not critical to
the unit's operation, therefore the unit will continue to operate. The alarm does not
protect the unit from water build up, it simply highlights the issue, therefore at every
occurrence of the alarm it should be investigated to find the cause and rectify the
issue. If an under unit drip tray is supplied it is ideal to mount the sensors within the
drip tray (see Fig. 5-1 on page 39).
