4.2 Requirements on Installation of the Water Manifold
(1) The water manifold should be installed on the wall or inside the special box. For housing constructions, it is
generally installed in the kitchen.
(2)
The valve for the water manifold should be installed horizontally and keep a distance of at least 300mm to
the ground.
(3) The water supply valve should be installed upstream of the water manifold and the return valve should be
installed downstream of the water manifold.
(4)
A filter is required upstream of the water manifold.
5 Selection of FCU
5.1 FCU Type Selection
The air-water fan coil unit is optional for Versati units.
5.2 Matching of Capacity
Load of the FCU is better to be between 70%~120% of the Versati unit.
Notes:
(a) When load of the FCU is too small, the unit would start/stop frequently, which is adverse for oil return.
(b) When load of the FCU is too large, the unit would always run under high frequency, which is unhelpful for
energy conservation.
