The Fan/pump control:
Fan and pump control are supplied as an option. The Fan/pump control comes as a set of different
parts.
-Temperature sensor for water temperature
-Startsensor (current clamp) to determent or compressor is on or off
-Fan/pump controller (the brain)
-Fan/pump box (connects to fan and pump)
The Fan/pump control makes the system even more efficient. The fan speed of the water cooler is
regulated depending on water temperature and the pump will only run when there is a need for
cooling. When the system is not in use, the pump will run a pre-defined cycle to prevent freezing in
colder climates. In cold climates a 20% or more glycol mix is recommended to prevent freezing.
-Setting up 1 Opticlimate on 1 water-cooler
The system is filled with water or glycol mix. The water supply (8) must be located at the lowest
point of the system. Automatic bleeders (2) must be located at the highest point of the system. A
manometer (4) is positioned on the both the return and supply side of the pump. The air separator
(5)must be located at a location where the pressure in a running system is the lowest. (pump intake)
The set
contains 2 ball valves, one to regulate flow (9) and one for the by-pass (3)
Air in the system reduces capacity and can damage pump or heat exchangers. Make sure air is
bleeded from the system after filling. Power the pump for a few seconds to bring air to the highest
point in the system. After bleeding, let the pump run full power, the air seperator will remove any
air bubbles that remain in the system. This can take a few minutes, hours or even days depending on
the layout of the piping.
