General information
3.1 Connection of the heat medium side
Primary and return lines of at least Ø22 mm copper pipe are to be connected
to the heat pump for CTC EcoPart 406-412, for CTC EcoPart 414-417, at
least Ø28 mm must be used. Route the pipes so that no other highest point is
present where air can collect and obstruct circulation. If however this cannot be
done, provide this highest point with an automatic bleeder.
3.1.1 Charge pump
The choice of charge pump depends on the type of system. To ensure proper
operation the flow in the heat medium circuit should not be less than the value in
the table under Technical data. Ensure that the circulation pump is large enough,
so that there is sufficient flow through the heat pump. If the flow is too low, there
is a risk the high pressure switch will trigger.
The charge pump can either be connected to the CTC EcoPart 400 (provided it
is installed internally) or connected to the product which is used to control it. For
internal installation one of the following is normally selected:
CTC EcoPart 406 - 408 Yonos Para PWM 7,0 Item no 586396 303
CTC EcoPart 410 - 412 Yonos Para PWM 7,5 Item no 586396 302
CTC EcoPart 414 - 417 UPM GEO 25-85 Item no 586396 301
3.1.2 Control/power supply
CTC EcoLogic Pro
Up to 10 heat pumps can be connected to a CTC EcoLogic Pro. In such a
case, the charge pumps in heat pumps 1 and 2 can be connected to the
CTCEcoLogicPro. A charge pump for heat pumps 3-10 must be installed and
connected to the CTC EcoPart 400.
CTC EcoLogic v3
The charge pump (not speed-controlled) must be connected to the
CTCEcoLogic v3.
CTC EcoZenith v3
Use a 0-10 V pump from CTC or a non speed-controlled pump connected to
the CTC EcoZenith.
CTC EcoEl v3
The charge pump (not speed-controlled) must be connected to the
CTCEcoElv3.

General information
3.2 Connecting the brine system
The brine system, i.e. the ground collector loop, must be assembled and
connected by a qualified tradesman in accordance with current regulations
and design guidelines.
Extreme care must be taken to ensure that no dirt gets on the collector
hoses, which must be washed clean before being connected. The protective
caps must remain in place at all times while work is in progress.
The temperature in the brine system can go below 0°C. This is why it is
important not to use any water-based lubricant etc. during installation. It is
also important that all the components are insulated against condensation to
prevent the build-up of ice.
Connections
The brine system may be connected to the right, left or top of the heat
pump, as well as to its rear. Cut away the cover plate on the side where the
brine system is to be connected. The insulation on the inside of the cover
plate has been grooved to enable an opening to be cut for the brine hoses
provided. When the opening has been made through both the insulation and
cover plate, carry out the installation as follows:
1. In order to protect the hoses, fasten the protective edging provided
around the edge of the opening in the insulation plate. Adjust the length
of the protective edging to suit the opening as required.
2. Pass the hoses through the opening in the side cover plates and connect
them. Ensure that the insulation covers all parts of the brine connection
to prevent ice and condensation forming.
3. Then install the collector system according to the schematic diagram
below.
You can also connect the primary flow on one side and the return on the
other. See the chapter on Measurement details for measurements and
dimensions. The pipe between the heat pump and brine loop should be not
less than Ø28 mm in dimension.
!We recommend
that you follow
the installation
instructions from
the local Heat Pump
Association.

Schematic diagram
The filling equipment is represented by the parts displayed with dashes. Note!
Collector hoses must have a bleeding facility as air pockets can occur. Always
check the filter (99) when filling and bleeding the brine system. !The mixing vessel
and pump must be
of a good size.

CTC EcoPart 400
General information
Valves
To facilitate servicing of the cooling unit, shut-off valves must be fitted to both
the incoming and outgoing connections. Fit bifurcated valves so that you can fill
and bleed the collector circuit later on.
Bleeding
The collector circuit must not contain any air. Even the smallest amount of air
can jeopardise the heat pump's operation. See the section Refilling and venting
below.
Insulation against condensation
All pipes in the brine system must be insulated against condensation to prevent
the possibility of severe build-up of ice and condensation.
Refilling and venting
Mix water and antifreeze solution in an open vessel. Connect hoses to the shut-
off valves (98a and 98b) as shown in the figure. Note! The hoses must have a
minimum diameter of 3/4”. Connect a powerful external pump (101) for refilling
and bleeding. Then reset the three-way valve (100) and open the valves (98a
and 98b) so that the brine passes through the mixing container (102). Also make
sure that the valve (98d) is open.
For start up of the brine pump, see the relevant manual for the
CTCEcoPart400’s controller.
Allow the brine to circulate in the system for a long period of time until it is
completely free of air. There can still be air in the system, even though no
air accompanies the liquid out. Reset the three-way valve (100) so that any
remaining air can come out.
Bleed the level vessel (96) by loosening the plug on top of the level tank.
Now close the valve (98a) while the filling pump continues to run. The filling
pump (101) now pressurises the system. Also close the valve (98b) and shut off
the filling pump.
If the level in the level vessel is too low, close the valves (98c and 98d). Unscrew
the plug and fill the vessel to around 2/3 full. Screw the plug back in and open
the valves (98c and 98d).
