Wall Mounted Split Units
What is all this about pumps?
Often forgotten about with split type air conditioning is the pump.
Do I need one ? This is totally dependent on where you are to mount your wall mounted indoor unit. All air conditioning systems dehumidify as they cool, the amount of water that is produced is dependant on the amount of water vapour in the atmosphere ( humidity). This water drips off the fin coils into a condense tray at the base of your indoor unit and then into a short flexible tube supplied by the manufacturer. Like the water in your sink it gravity drains away, it will not go "upwards" If your indoor unit backs onto an outside wall its easy just extend the short flexible tube and take to a suitable rain water point.
When do I need a pump ? If your indoor unit is mounted on an internal wall and you are to run your pipes and services into a loft or false ceiling above the water needs to be forced (pumped). If your drain is extended or rises at any point you will also need a pump.
If so which one ? There are lots of pumps, In our view the most reliable is the Peristaltic Pump. The peristaltic pump "lifts" the water from the indoor unit and pumps the water away. Some of these pumps can lift the water to 4 mtrs and have a "pumping head" of 10 mtrs. Other pumps can be fitted directly on the short manufacturers hose and work on "sensing "water which starts the pump, when the water has gone the pump stops.
