5.5.5 Condensate pump
When installing a condensate pump:
• Never run power supply cables for the condensate pump together with control
cabling
• Position the condensate pump carefully and secure it against slipping
• Where ever possible consider future servicing needs where this pump may have to
be removed and cleaned as part of a maintenance program
• Fitting the condensate pump outside of the unit casing offers the best access
• Care must be taken that condensate inlet and outlet are not placed beneath the fan
• Ensure that no power or water hoses can contact the fan, if necessary, suitable
condensate hose bracketing should be installed
For cold water condensate pumps (units without a humidifier):
Pump Capacity: 4 litres
Max. recommended
Discharge Height:
7 metres
Max. Flow Rate: 800 liters per hour for 1 meters of discharge head
180 liters per hour for 7 meters of discharge head
For hot water condensate pumps (units with a humidifier):
Pump Capacity: 4 litres
Max. recommended
Discharge Height:
7 metres
Max. Flow Rate: 850 liters per hour for 1 meters of discharge head
350 liters per hour for 7 meters of discharge head
5.5.6 Remote monitoring touch screen display
• The display can be mounted up to 50 m away from the C5-12 controller within the
Multi-DENCO unit.
• A 24 VAC supply is required, local, to power the display, together with a two
core screened data cable that networks the display to the pLAN connection on the
C5-12 controller. For further details refer to the wiring diagram.

5.5.7 Ambient Temperature Sensor
This item will be supplied loose within your Multi-DENCO unit. This sensor must be
installed for the FreeCool functions to operate.
The sensor must be:
– Installed as near as possible to the Hybrid Heat Rejection Unit (DMOUHM)
– NOT installed in a location that receives direct sunlight
– Not exposed to exhaust heat from other mechanical equipment
– Positioned to give the best representation of the ambient temperature as possible
When a humidifier is fitted, condensate collected in drip trays and condensate
pumps can be at near boiling temperatures. This condensate, or surfaces that it
has been in contact with, can cause scalding or burns.
• The installer must install condensate tubing suitable for these temperatures.
• The installer must ensure individuals cannot come in contact with this fluid, tubing
or affected regions.
