CTC EcoZenith i250
Installation
Expansion vessel connection
The CTC EcoZenith i250 is best connected to a closed expansion vessel.
The CTC EcoZenith i250 is designed to be fitted to an 18 l closed expansion
vessel. The expansion vessel is either fitted in the area under the tank or on
top of the product (see pictures). The expansion vessel with installation kit is
available as an accessory.
!
NB: If the heat pump is not connected, the
connections not being used must be capped off!
If you connect the product to an open system, the distance between the
expansion vessel and the highest placed radiator must not be less than 2.5
metres in order to avoid introducing oxygen into the system.
Note that no hot water circulation may be connected as it affects the
function of the EcoZenith and the system. If the EcoZenith i250 is connected
to another heat source, e.g. an existing boiler, the installations must have
separate expansion vessels.
Water taps
In some cases, unusual noises may be produced by the house’s pipe
system and the EcoZenith i250 due to the jolts which occur when the flow
is quickly interrupted. There is no fault with the product, but the noise may
occur when older model outlets are used. More recent outlets are often fitted
with a soft-closing mechanism. Alternatively, a shock arrestor can be fitted.
Keeping the jolting to a minimum also helps avoid unnecessary wear and
tear affecting the DHW system.
