Details identified by the word "Note" contain additional information.

Target group

These instructions are exclusively intended for authorised contractors.

Work on the refrigerant circuit may only be carried out by authorised refrigeration engineers.
Work on electrical equipment must only be carried out by a qualified electrician.
The system must be commissioned by the system installer or a qualified person authorised by the installer.

Regulations to be observed

Safety instructions for working on the system

Working on the system

Isolate the system from the power supply, e.g. by removing the separate fuse or by means of a mains isolator, and check that it is no longer live.
Note
In addition to the control circuit there may be several power circuits.

Contact with live components can result in severe injuries. Some components on PCBs remain live even after the power supply has been switched off.
Prior to removing covers from the appliances, wait at least 4 minutes until the voltage has completely dropped out.

Safeguard the system against reconnection.
Wear suitable personal protective equipment when carrying out any work.

Hot surfaces and fluids can lead to burns or scalding.

Before maintenance and service work, switch OFF the appliance and let it cool down.
Never touch hot surfaces on the appliance, fittings or pipework.

Risk of fire: Electrostatic discharge can cause sparks which may be ignited by escaping, flammable refrigerant (R32).
Before beginning work, touch earthed objects, such as heating or water pipes, to discharge any static.

! Please note
Electronic assemblies can be damaged by electrostatic discharge. Prior to commencing work, touch earthed objects such as heating or water pipes to discharge static loads.

Work on the refrigerant circuit

Refrigerants are air displacing, colourless, odourless gases.

R32 forms flammable mixtures with air.
R410A is not flammable.

Direct contact with liquid and gaseous refrigerant can cause serious damage to health.

Avoid direct contact with liquid and gaseous refrigerant.
Wear personal protective equipment when handling liquid and gaseous refrigerant.

Unregulated escape of refrigerant in enclosed spaces can lead to breathing difficulties and suffocation.

Never breathe in refrigerant vapours.
Ensure adequate ventilation in enclosed spaces.

Perform the following measures before beginning work on the refrigerant circuit:

Check the refrigerant circuit for leaks.
Ensure very good ventilation especially in the floor area and sustain this for the duration of the work.
Inform all persons in the vicinity of the system about the type of work to be carried out.
Secure the area surrounding the work area.

Further measures before starting work on the refrigerant circuit with flammable refrigerants (R32):

Remove all flammable materials and ignition sources from the immediate vicinity of the heat pump.
Before, during and after the work, check the surrounding area for escaping refrigerant using a suitable refrigerant detector.
This refrigerant detector must not generate any sparks and must be suitably sealed.
CO₂ or powder extinguisher must be to hand in the following cases:
- Refrigerant is being topped up.
- Soldering or welding work is being carried out.
Display signs prohibiting smoking.

Damage to the refrigerant circuit can cause refrigerant to enter the hydraulic system. This can cause serious damage to health.
After completion of the work, professionally vent the hydraulic system on the primary and secondary sides.

Repair work

! Please note
Repairing components that fulfil a safety function can compromise the safe operation of the system. Replace faulty components only with genuine Viessmann spare parts.

Auxiliary components and spare and wearing parts

! Please note
Auxiliary components, spare parts and wearing parts that have not been tested together with the system can compromise its function. Installing non-authorised components and making non-approved modifications or conversions can compromise safety and may invalidate our warranty.
For installation and replacements, use only Viessmann original parts or parts approved by Viessmann.

Safety instructions for operating the system

What to do if water escapes from the appliance

If water escapes from the appliance there is a risk of electrocution.
Switch OFF the heating system at the external isolator (e.g. fuse box, domestic distribution board).

If water escapes from the appliance there is a risk of scalding.
Never touch hot heating water.
