Instructions for installation and use VX Solo 22
4. Enduser instructions, description and initial adjustment
Instructions
Please read these instructions carefully before installing and com­missioning this unit. The manufacturer accepts no liability for loss or damage resulting from failure to comply with these instructions for use. Read and follow these instructions carefully to prevent the risk of physical injury and/or damage to property. Exceeding the recommended operating parameters appreciably increases the risk of personal injury and/or damage to property.
Installation, commissioning and maintenance must be carried out by qualied and authorised personnel (both plumbing and electri­cal work). Once the station has been installed and is operating, there is nor- mally no need to alter the settings or other functions. The district heating unit is very reliable and easy to operate.
Warning! Hot surfaces
Parts of the unit may be very hot and can cause burn injuries. Be very careful when you are in the immediate vicinity of the unit.
Warnings about high pressure and high temperature
The maximum supply temperature in the district heating net­work can be up to 120°C and the operating pressure can be up to 16 bar. This may result in a risk of scalding from touching the unit and from outow of the medium (water/steam). Exceeding the unit design data and operating parameters for pressure and temperature carries an appreciable risk of personal injury and/or damage to property.
Description
These instructions apply to two unit types. One variant with Danfoss ECL Comfort 310 controller with night-time duty for control of the heating circuit only (Application A230) as well as a variant with Danfoss ECL Comfort 310 controller for control of both the heating circuit (incl. night-time duty) as well as a DHW cylinder circuit (Ap­plication A266).
VX Solo 22 units are tted with a dierential pressure controller that maintains a constant pressure in the radiators. For both VX Solo 22 applications the supply temperature to the heating circuit is con­trolled electronically. For VX Solo 22, application A266, the temperature in the DHW cyl­inder is also controlled electronically.
We recommend regular inspections of the unit - ideally in connection with readings of the district heating meter. Pay special attention to any leaks and an excessively high return temperature in the district heating circuit (poor cooling of the district heating water). Cooling – i.e. the dierence between the supply and re­turn temperature of the district heating water – has a signicant eect on the overall energy economy. Please note that the district heating return temperature is directly related to the return temperature from the heating circuit (and the return temperature from the domestic hot water cylinder). Therefore, it is important to focus on the supply and return temperature in the heating system. The dierence should typically be 30–35°C in systems that operate with radiators. In systems that feature oor heating, the dierence is typically 5–10°C.
Emergencies
In the event of re, leaks or other hazards, immediately shut o all sources of energy to the unit, if possible, and call for appropri­ate assistance. If the domestic hot water is discoloured or malodorous, shut o all ball valves on the unit notify all users and call for professional assistance without delay.
Initial setting
VX Solo 22 is electronically controlled (fully automatic) and there is normally no need to alter the settings or other functions. The DHW (Application 266) and HE temperatures are set during initial adjustment and commissioning of the unit. We suggest that you contact qualied and authorised personnel, if it becomes necessary to change the parameters (temperatures, night-time reduction etc.) in the controller.
Irregularities
When reading the meter, check all joints and connections for leaks.
If you identify any irregularities/leaks, contact your professional provider for assistance.

5. Installation instructions, connection, safety and handling
Instructions
Please read these instructions carefully before installing and com­missioning this unit. The manufacturer accepts no liability for loss or damage resulting from failure to comply with these instructions for use. Read and follow these instructions carefully to prevent the risk of physical injury and/or damage to property. Exceeding the recommended operating parameters appreciably increases the risk of personal injury and/or damage to property. Installation, commissioning and maintenance must be carried out by qualied and authorised personnel (both plumbing and electri­cal work).
Heat source
The unit is primarily designed for connection to district heating. Alternative energy sources can be used if the operating conditions are equivalent to district heating at all times.
Application
The unit is designed exclusively to heat water. The unit must not be used to heat other media. The unit is to be connected to the household piping in a frost-free room, where the temperature does not exceed 50°C, and where the relative humidity is not higher than 80%. The unit must not be cov­ered, bricked in or otherwise cut o from access.
Choise of materials
Only use materials that comply with local regulations.
Connection
It must be possible to cut o all energy sources to the unit – including electrical connections – at all times. The unit must be connected to an electrical equalizer connection.
Potential equalization/grounding
Potential equalization is an electrical equalizer connection to secure against user contact with dangerous voltage, which may occur for example between two piping systems. Potential equalization reduces corrosion in heat exchangers, water heaters, district heating units and plumbing installations. Equalization of potentials should be eected according to local regulations.
Warning! Hot surfaces
Parts of the unit may be very hot and can cause burn injuries. Be very careful when you are in the immediate vicinity of the unit.
Warnings about high pressure and high temperature
The maximum supply temperature in the district heating network can be up to 120°C and the operating pressure can be up to 16 bar. This may result in a risk of scalding from touching the unit and from outow of the medium. Exceeding the unit design data and operating parameters for pressure and temperature carries an appreciable risk of personal injury and/or damage to property.
Corrosion
The maximum chlorine content of the medium must not be higher than 300 mg/l. The risk of corrosion increases considerably if the recommended chlorine content is exceeded.
Safety valve(s)
Safety valves must always be installed in accordance with the appli­cable local regulations.
Noise level
≤ 55 dB
Storage
Before installation, the unit(s) must be stored in a dry, heated (i.e. frost­free) room. (Relative humidity max. 80% and storage temp. 5–70°C). The units must not be stacked higher than the limit at the factory. Units supplied in cardboard packaging must be lifted using the handles incorporated in the packaging. Units must be placed on pallets for transport/moving across large distances. As far as possible, do not lift the unit by the pipes. Lifting by the pipes may cause leaks. REMEMBER to retighten.
Emergencies
In the event of re, leaks or other hazards, immediately shut o all energy sources to the If the valves on the unit, notify all users and call professional assistance with­out delay.
Warning about damage during transport
On reception of the unit, and before installing it, check for any evidence of damage during transport. The unit must be handled and moved with the greatest care and at­tention.
NB! - Tightening of connections
Before lling the unit with water, ALL pipe connections MUST be retightened, as vibrations during transport may have caused leaks. Once the unit has been lled and the system is hot, ALL pipe connec­tions MUST be retightened once more. DO NOT OVERTIGHTEN THE PIPE CONNECTIONS – see page 9, “Test & connections”.

General information
PLEASE NOTE! Some models may have a slightly dierent appearance, but the control function is in principle the same as described below.
Commissioning
Commission the unit in accordance with the instructions on page 8 -10.
Filling the system
Filling of water to the heating system must be done through con­nection to an exterior cold water supply. Check and tighten all connections before adding water to the system, as vibrations during transport may have caused leaks. After having added water to the system, tighten all the connections before per­forming leak test. Then heat up the system, check the connections and tighten once again if necessary.
Before adding water to the system and rst start-up, check if:
- pipes are connected according to the circuit diagram,
- expansion vessel is connected,
- heat meter is mounted,
- shut-o valves are closed,
- threaded and anged connections are tightened.
Filling the system - (Note, by means of exterior cold water supply):
1. Pump must be switched o when water is added to the system.
2. Fill heat exchanger and system with water until the manometer shows a working pressure, which corresponds to the system height + 5 m (approx. 1.5 - 2.0 bar)
3. Vent the system completely.
4. Start the pump.
Dierential pressure controller (common return pipe
- only Application A266)
The dierential pressure controller, Danfoss AVP-F reduces the high uctuations in pressure in the district heating network, ensuring a small and constant operating pressure across the unit. This ensures optimum operating conditions for the control equipment.

Pump - Wilo Stratos PARA / Yonos PARA (system with ECL)
The pump is factory connected to the ECL controller. On systems with ECL controller turn the red switch to the right (con­stant curve) and set it to “Max. pos.” initially. Then set the pump to the lowest possible position, depending on the heating requirement for the building - taking into account aspects such as cooling and power consumption.
Venting: The pump features a built-in venting function, which can be used when the system needs to be bled. Turn the red switch to the vertical position. The pump will then run a venting routine that lasts 10 minutes. There may be some noise during this phase. Once the 10-minute period is nished, reset the pump according to the instructions above. For additional information, see the manual: Wilo Stratos PARA /
Yonos PARA.
Summer operation (all pump types) Outside the heating period, the pump will be disconnected automati­cally from the heating system. During the summer period, the control­ler will start the pump for a minute at least once every three days to prevent the pump from blocking.

12. Operation and maintenance
Meter reading
The caretaker/owner must perform visual checking and reading of the district heating meter at short, regular intervals in accordance with the maintenance plan, page 16. (Please notat that the meter is not a part of the delivery from Danfoss). Service procedures must only be performed by trained, authorised personnel. NB! Excessive consumption for whatever reason is not covered by the Danfoss warranty.
Inspection
The unit should be checked regularly by authorised personnel. Any necessary maintenance must be performed in accordance with the instructions in this manual and other sets of instructions. During service the dirt strainers are to be cleaned – including the lter on the controller, all pipe connections must be tightened and the safety valve (pos. 11) must be function tested by turning the lever. Always lead the blow-o pipes from the safety valves to a drain in accordance with applicable legislation.
Rinsing/cleaning of pla te heat exchanger
To clean the plate heat exchanger, rinse it by running clean water through the exchanger at high speed and in the opposite direction to the normal flow. This will remove any dirt deposits that may have built up in the exchanger. If rinsing with clean water is not sufficient, the ex­changer can also be cleaned by circulating a cleaning agent approved by Danfoss (e.g. Radiner Fl cleaning fluid) through the exchanger. Use an environmentally friendly cleaning fluid, which can be disposed off through the standard sewer system. After use of a cleaning fluid, the plate heat exchanger must be rinsed thoroughly with clean water.
11
Venting
During start-up (of the heating season) always vent the radiator cir­cuit/heating side, the pump and the unit. To vent the unit, use the air valve (pos. 12)) in the unit. Vent the radiator circuit/heating side on the bleed screws of the radiators. Vent the pump according to instructions in the pump manual.
Measures after maintenance work
After maintenance work and before commissioning: – Check that all screwed connections are tight. – Check that all safety features, covers, that were removed, have been
replaced properly. – Clean the working area and remove any spilled materials. – Clear all tools, materials and other equipment from the working area. – Connect to energy supply and check for leaks. – Vent the system. – Carry out any necessary adjustment again. – Make sure that all safety features on the device and the system work
properly.
Cooling / Return temperature reading
Cooling – i.e. the dierence between the supply and return tempera­ture of the district heating water – has a signicant eect on overall energy economy. Please note that the district heating return tem­perature is directly related to the return temperature from the heat­ing circuit (and the return temperature from the domestic hot water cylinder). Therefore, it is important to focus on the supply and return temperature in the heating system. The dierence should typically be 30–35°C in systems that operate with radiators. In systems that feature oor heating, the dierence is typically 5–10°C. In these systems the supply temperature should not exceed 35°C.

Commissioning certicate
The unit is the direct link between the district heating supply network and the household piping system. All supply pipes and the pipes in the household piping system must be checked and rinsed before commissioning. Once the system has been lled with water, all pipe con­nections must be retightened before performing pressure test for leaks. The dirt strainers must be cleaned and the unit must be adjusted in accordance with the instructions in this manual.
It is important to comply with all technical regulations and the applicable legislation in every respect.
Installation and commissioning must only be performed by trained, authorised personnel.
The unit is checked in the factory for leaks before delivery. Leaks are however possible due to vibrations caused by transport, hand-ling and heating of the system and therefore it is important to check all connections and to retighten if necessarys before commissioning. Please note that the connections may feature EPDM gaskets! Therefore it is important that you DO NOT OVER-TIGHTEN the connections. Over-tightening may result in leaks. Leaks caused by ove-rtightening or failure to retighten connections are not covered by the warranty.
