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”.
Handling
We recommend that you wear suitable safety footwear while handling and installing the unit. We recommend that you wear suitable safety working gloves while handling and installing the unit. Do not remove any transport brackets until the unit is in the immediate vicinity of the installation site.
