CTC EcoZenith i550 Pro
For the installer
Drainage valve
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 exceed 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.
