CTC EcoZenith i555 Pro
Fit the drain valve (separate package) to one of the EcoZenith’s lower
connections. The adapter for this is provided in the package. The drain valve
can also be fitted into a low lying pipe.
Manometer – system pressure
Fit a manometer to the expansion pipe or radiator return pipe.
Expansion vessel connection
The EcoZenith is best connected to a closed expansion vessel. If an open
system is used, the distance between the expansion vessel and the highest
placed radiator must not be below 2.5 m, in order to avoid introducing
oxygen into the system.
Insulation
To ensure best efficiency, make sure that after installation you insulate all
pipe parts, pipe unions and used and unused plugged connections. Use the
insulation parts provided, and supplement these with insulation of Armaflex
type having minimum 10–15 mm thickness, or equivalent. Make sure the
insulation at the connections reaches all the way to the EcoZenith’s own
insulation and that it has no gaps, so as to prevent any loss of heat.
Pressure/level switch
In some cases, extra protection is required due to local requirements or
provisions. For example, the requirement in some areas is for the system to
be installed within a water catchment area.
The pressure/level switch connects to terminal blocks K22/K23/K24/K25
and is then defined in the "Installer/Define/Def. Heat Pump" menu. If there
is a leak, the compressor and brine pump stop and the "Flow/level switch"
alarm appears on the display.
