Congratulations on buying your new product!
The complete heat pump for rock, ground or lake
CTC EcoPart 400 is a heat pump that draws heat from bedrock, the ground
or a lake and conveys it to the existing heating circuit in your house. CTC
EcoPart 400 is fully utilised before the normal heating circuit is switched on
and helps heat the house.
The heat pump can be connected to CTC EcoZenith or to an existing boiler
via the CTCEcoLogic control system.
The CTC EcoPart 400 has been designed to operate with high efficiency and
low noise level.
Save this manual containing the installation and maintenance instructions.
If it is looked after properly, you will be able to enjoy the use of your CTC
EcoPart 400 for many years. This manual will provide all the information you
will need.
CTC EcoPart 400 is available in multiple versions
CTC EcoPart 406-417 (LEP)
• A-rated brine pump (Low Energy Pump - LEP)
• No charge pump
CTC EcoPart 414-417 2xLEP
• A-rated brine pump (Low Energy Pump - LEP)
• A-rated charge pump (Low Energy Pump - LEP)

3. Installation
This section is aimed at anyone responsible for one or more of the
installations required to ensure that the product works the way the property
owner wants.
Take your time going through functions and settings with the property owner
and answer any questions. Both you and the heat pump benefit from a user
who has completely understood how the system operates and should be
maintained.
The installation must be carried out in accordance with current standards
and regulations. Refer to BBR-99 and the Warm and Hot Water Instructions
1993. The product must be connected to an expansion vessel in an open
or closed system. Do not forget to flush the heating circuit clean before
connection. Apply all the installation settings based on the description in the
chapter on “First start”.
The heat pump operates with a primary flow/return temperature across the
condenser of up to 65/58°C.
Transportation
Transport the unit to the installation site before removing the packaging.
Handle the product in the following manner:
• Forklift
• Lifting band around the pallet. NB: Can only be used with the
packaging on.
Unpacking
Unpack the heat pump when it is placed next to its installation site. Check
that the product has not been damaged in transit. Report any transport
damage to the carrier. Also check that the delivery is complete according to
the list below.
Delivery includes:
• CTC EcoPart 400 heat pump
• Safety valve 1/2" 3 bar

in an upright position.

16 CTC EcoPart 400
3.1 Connection of the heat medium side
Primary flow and return lines must routed to the heat pump using copper pipes of at
least Ø22 mm for CTC EcoPart 406-412. For CTC EcoPart 414-417, copper pipes of 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 Circulation pumps (charge pump)
The choice of heat medium 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 heat medium pump can either be connected to 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 Prod. no. 587477 303
CTC EcoPart 410 - 412 Yonos Para PWM 7.5 Prod. no. 587477 302
CTC EcoPart 414 - 417 UPM GEO 25-85 Prod. no. 587477 301
3.1.2 Control/supply
CTC EcoLogic Pro
CTC EcoLogic Pro can be connected with up to 10 heat pumps. The heat medium
pumps in heat pumps 1 and 2 can then be connected to CTCEcoLogicPro.
Heat medium pumps for heat pumps 3-10 must be installed and connected to
CTCEcoPart400.
CTC EcoLogic v3
The heat medium pump (not speed-controlled) must be connected to 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 heat medium pump (not speed-controlled) must be connected to CTCEcoElv3.

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 of the brine system can fall below 0°C. It is therefore
important that no water-based lubricants and similar are used 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 section "Brine system
schematic diagram".
It is also possible to connect the primary flow on one side of the heat pump
and the return on the other. Refer to section "Dimensions diagram" for
measurements and dimensions. The pipe dimension between the heat pump
and brine loop should be not less than Ø28 mm.

The filling equipment is represented by the parts displayed with dashes.
NB: 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.

19CTC EcoPart 400
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.
Filling 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. NB: 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 EcoPart’s
controller.
Allow the brine to circulate in the system for a long period of time until it is
completely free of air. There could still be air in the system, even though
no air accompanies the liquid out. Reset the 3-way valve (100) so that any
remaining air can come out.
Bleed the level vessel (96) by loosening the plug on the top of the level
vessel.
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).
