CTC EcoZenith i250
Installation
12.3 Connection to heat pump
The heat pump is connected to the top (CTC EcoZenith i250L, see figure
below) or bottom (CTC EcoZenith i250H).
The charge pump for the heat pumps is factory-installed in the
CTCEcoZenith i250L.
The CTC EcoZenith i250 L has pipes at the rear right edge for connection of
the heat pump.
The CTC Eco Air’s lower connection (5) is connected to the right connection
(2) when viewed from the front, so that water is pumped out to the heat
pump. The CTC EcoAir's upper connection (4) is thus connected to the left
connection (1).
The CTC EcoZenith i250 H heat pump is connected directly to the supplied
charge pump (3) located under the tank. The heat pump’s lower connection
(5) must be connected to the charge pump (3) so that water is pumped out
to the heat pump. The heat pump’s upper connection is connected to the
right diverting valve (viewed from the front).
Draining: A drain valve must be fitted to the EcoZenith’s left connection
(where the charge pump is mounted). It functions as drainage for both the
boiler and the radiator system.
