3. Pipe installation
3.1
General
This chapter is intended for anyone responsible for the installation. Take
your time going through functions and settings with the property owner
and answer any questions. Installation must be performed by a qualified
professional.
3.2
Mounting
CTC EcoComfort must be mounted on the wall with the wall bracket
provided. Fasten the bracket with suitable screws (not included) for the type
of wall material. Make sure the bracket is screwed securely in a horizontal
position. Then hang the box on the bracket and secure with a screw in
the mounting ear underneath the box. For offset dimensions, see sections
Dimensional drawing and Technical data .
3.3
Water quality, cold side
Approved antifreeze liquids are propylene/ethylene glycol and ethyl alcohol
with max. 30% concentration by volume. The suitability of other antifreeze
liquids can be considered after checking the materials used in constituent
components. Note that the unit capacity is specified for ethyl alcohol which
is 30% by volume.
3.4
Water quality, hot side
The radiator system's water flow passes through the heat exchanger
in CTC EcoComfort. This is why the radiator system must be flushed
thoroughly before installation. If dirt is to be expected, the installation of a dirt
filter before EcoComfort is recommended.
3.5
Delivery inspection
Check that the product has not been damaged in transit. Report any
transportation damage to the carrier. Check that the delivery is complete.
3.6
General comment on pipe
installation
The installation must be carried out in accordance with current standards
and regulations.
3.7
Connection to the heating system
The outgoing water (cooled water) from EcoComfort is connected to a fan
coil unit or to the heating/cooling system via a diverting valve (Y60). See
chapters Schematic diagrams and Connecting the diverting valve (Y60) . The
cooling flow back to EcoComfort should be connected to the heating/cooling
system's return line.
In cases where one or more fan coil units are connected, it is the return
water from the fan coil system that is connected to the cooling unit's
incoming pipe. Note that the cooling unit does not contain a circulation
pump for the hot side; this must be dimensioned and connected separately.
