CTC EcoZenith i550 Pro
For the installer
13. Pipe installation
The installation must be carried out in accordance with current heating and
hot water standards. See BBR (Boverkets Byggregler) and Warm and Hot
Water Recommendations (Varm- och hetvattenanvisningar (VVA 1993)). The
product must be connected to an expansion vessel in an open or closed
system. Do not forget to flush the radiator system clean before connection.
Perform all the installation settings based on the description in the chapter
on “First start”. See the chapter on the EcoZenith’s functions in the section
for the property owner for more information on the function of the various
parts of the system.
This chapter contains the main connections for the EcoZenith, plus additional
installations such as heat pumps, tanks, solar energy, pool, passive cooling,
bore hole charging, DHW circulation and external gas, oil or pellet boiler. The
instructions for the relevant additional product should be followed.
Refer also to the “Electrical installation” chapter.
Connections, placement and dimensions
See Technical data in the section for the property owner.
Pipe connections on the unit
Connect the pipes as shown in the schematic diagram for pipe connections.
Also refer to Technical data in the section for the property owner for
connection dimensions and placement. If annealed copper pipe is used, fit
support sleeves.
Circulation pumps - radiator system
The circulation pumps are fitted to the primary flow piping from the
EcoZenith to the respective radiator systems and receive their power supply
from the EcoZenith, see chapter on Electrical installation.
Mixing valve
Install a mixing valve where there is outgoing hot tap water in order to avoid
the risk of scalding at the property’s hot tap water points.
Safety valves
The EcoZenith safety valves for the tap water circuit and boiler are packaged
separately. Connect the waste pipes to the waste system directly to the
floor gully or, if the distance is more than two metres, to a funnel. Water can
drip from a connected waste pipe. The waste pipe must incorporate a fall
towards the floor gully, be installed so that there is no risk of freezing and be
left open to the atmosphere/without pressure. The length of the waste pipe
may not exceed two metres, unless in these cases it exits into a funnel.
Filling valve – radiator system
Fit a filling valve between the cold water connection and the radiator return
pipe, or between the cold water pipe and the expansion pipe. The filling
valve must be provided with a non-return valve (to prevent backflow).
