The manufacturer declines all liability due to printing or transcription errors, reserving the right to make any modifications to its technical and commercial documents without forewarning.

INSTALLING THE DEVICE

DESCRIPTION OF THE DEVICE.
This kit proposes for the management of zones heating and cooling systems with large water capacities. In particular, it is a kit that can be combined exclusively with Magis Pro 4-6-9 V2, Magis Combo 4-6-9 V2 , Magis Combo Plus 4-6-9 V2, Magis Hercules Pro Mini 6-9, Magis Hercules Pro Mini EH 6-9 and designed to manage 1 mixed and 1 direct zone.
The kit is characterised by the possibility to be recessed into the wall, therefore having no clearance.
Each zone served by the kit is managed by an appropriate tem-perature control connected to the heat generator.
INSTALLATION RECOMMENDATIONS.
Only professionally qualified heating/plumbing technicians are authorised to install Immergas kits. Installation must be carried out according to regulation standards, current legislation and in compliance with local technical regulations and the required technical procedures. Before installing the device, ensure that it is delivered in perfect condition; if in doubt, contact the sup-plier immediately. Packing materials (staples, nails, plastic bags, polystyrene foam, etc.) constitute a hazard and must be kept out of the reach of children. In the event of malfunctions, faults or incorrect operation, turn the device off immediately and contact a qualified technician (e.g. the Immergas Technical Assistance centre, which has specifically trained staff and original spare parts) Do not attempt to modify or repair the appliance alone. Failure to comply with the above implies personal responsibility and invalidates the warranty.
- Recess installation.
- Prepare the masonry creating an opening in the wall suitable to contain the kit (see dimensions on the next page).
- Insert the kit (1) into its seat, remembering to open the four sup-port fins (2) before insertion (see Fig. 1).
- Protect the side edges and the front cover during recess preparation for the device.
- N.B.: because the hydraulic and electric connections between system and kit must be inside the clearance of the device itself, first position the kit and then the system input and output pipes and the electric cable ducts.
- Attention : the recessed kit is not a supporting structure and can-not replace the piece of wall removed. It is therefore necessary to check the correct positioning inside the wall.
- For safety reasons, it is necessary to carefully seal the housing compartment of the kit in the wall, in compliance with Standards in force.
  N.B.: leave the drain holes located under the front door open. Otherwise, if water should enter, it could not go out.
Wall-hanging installation.
Fasten the kit to the wall using four expansion plugs, suitable for the type of wall and weight of the device (not supplied) and using the four drilled holes (see Fig. 2 pos. X).
Use the fairlead and the sheath-holder (3) supplied to limit the infiltration of water inside the frame.

HYDRAULIC CONNECTION.

Attention: before making the appliance connections, clean the heating system thoroughly (pipes, radiators, etc.) with special pickling or de-scaling products to remove any deposits that could compromise the correct operation of the device.
Provide a chemical treatment of the thermal system water, in compliance with the local norms, in order to protect the system and the appliance from deposits (e.g., lime scale), slurry or other hazardous deposits.
The hydraulic connections must be made in a rational manner using the values as per Fig. 2.
IMPORTANT: remove all the protection caps from the system flow and return pipes before making the hydraulic connections. The connections can be made directly using the female couplings on the distribution manifold or by inserting system cut-off cocks (optional). These cocks are particularly useful for maintenance as they allow you to drain the distribution manifold separately without having to empty the entire system.
\N.B.: the manufacturer does not supply the G1” cocks to be in-stalled in the low-temperature zone.
Check that the expansion vessel in the heat generator allows for the increase in volume of the water resulting from its central heating without opening the safety valve. If this is not the case, an expansion vessel with appropriately dimensioned capacity must be installed on the system.
The kit is set up for the insertion of the automatic “jolly” vent valve to be mounted on the manifold. This is recommended for better air venting inside the system.

ELECTRICAL CONNECTION.

The kit has a protection rating of IPX4D. Electrical safety of the device is reached only when it is correctly connected to an efficient earthing system as specified by current safety standards.
Attention: the manufacturer declines any responsibility for dam-age or physical injury caused by failure to connect the device to an efficient earth system or failure to comply with the reference IEC standards.
Also ensure that the electrical installation corresponds to maxi-mum power absorbed by the device, as shown on the data-plate inside the recess.
Important: it is mandatory to prepare two electrical connection lines in order to separate the power supply in high and low voltage, according to the standards in force regarding electrical systems.
These lines must arrive inside the kit via relevant sheaths or ducts passing through the fairlead and the sheath-holder supplied, situated on the upper side of the device.

COMMISSIONING THE DEVICE.

System filling. When the device has been connected, fill the system.
Filling is performed at low speed to ensure release of air bubbles in the water via the heating system vents.
Close radiator vent valves when only water escapes from them. Close the filling cock when the heat pump pressure gauge indicates approx. 1.2 bar.
N.B.: during these operations activate the system vent function of the hydronic unit (see relative instruction booklet)

SIZING THE SYSTEMS.
Check that the design parameters allow obtaining a maximum surface temperature of the radiant floor in compliance with that established by the Standard.

KITS AVAILABLE ON REQUEST.

System cut-off cock kit (on request). The kit is designed for the installation of system interception cocks, to be placed on the flow and return pipes of the connection assembly. This kit is particularly useful for maintenance as it allows the kit to be drained separately without having to empty the entire system.
The above-mentioned kit is supplied complete with instructions sheet for assembly and use.

CIRCULATION PUMP.

The kit is supplied with circulator fitted with speed regulator. These settings are suitable for most systems.
In fact, the pump is equipped with electronic control to set advanced functions. For proper operation one must select the most suitable type of operation for the system and select a speed in the available range, with a focus on energy savings.
Selection of operating mode.
When running, the pump indicates the set configuration by means of the codified lighting of the LEDs. The setting is changed by a short pressing of the button.

USE AND MAINTENANCE INSTRUCTIONS

GENERAL WARNINGS.
If the device must be deactivated temporarily, act directly on the main switch to power off the system and work safely

Attention: using any components that use electrical power requires the observation of some fundamental rules:C
- do not touch the device with wet or moist parts of the body; do not touch when barefoot.
- if the device is wall-mounted: do not pull the electric cables, do not leave the device exposed to the elements (rain, sun, etc.);
- in the event of damage to the cable, switch off the device and contact exclusively qualified staff for replacement;
- if the device is not going to be used for a certain period, discon-nect the main power switch.
WARNINGS FOR THE USER.
- This device does not require any regulation or control by the user; the opening of the device front lid is therefore prohibited.
- The only operation that the user must perform is to periodically check the water pressure of the system in the heat generator. The heat generator pressure gauge should read a value of between 1 and 1.2 bar.
- If the pressure is below 1 bar (with the circuit cool), restore normal pressure.
- N.B.: if pressure values reach around 3 bar the boiler safety valve may be activated.
- In this case contact a professional technician for assistance.
- In the event of frequent pressure drops, contact qualified staff for assistance to eliminate the possible system leakage.
CLEANING THE CASE.
- Use damp cloths and neutral detergent to clean the kit casing. Never use abrasive or powder detergents.

CHECKS AND MAINTENANCE

make sure the heating/cooling system is filled with water and that the manometer indicates a pressure of 1÷1.2 bar;
make sure that the air valve cap (if present) is open and that the system is appropriately de-aerated;
check the sealing efficiency of water circuits;
check the correlation between the electric and hydraulic connections;
If even only a single safety check offers a negative result, do not commission the system..
