1 Important information

⚠ This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved.

Cleaning and user maintenance shall not be made by children without supervision.

Children should be supervised to ensure that they do not play with the appliance.

T he insta llation must only be carried out by an authorized installer with reference to applicable rules and orders and these installation instructions.

This a pparatus is not intended for persons (including children) with reduced physical, sensory or psychological capacity, or who do not have knowledge or experience, unless supervised or they have received instructions on how the apparatus functions from a safety qualified person.

⚠ The he at pump must be located in a frost-free environment!

The f loor must be able to support the gross weight of the heating installation.

T he h eating installation must be placed on a stable surface.

⚠ Befo re the heat pump is supplied with voltage you must ensure that the heating system and coolant system. incl. the heat pump. are filled and bled of air otherwise the circulation pumps can be damaged.

⚠ If the electrician wishes to test his connections before the above is carried out this should only done when it has been checked that the heat transfer fluid and coolant pumps have been disconnected.

⚠ W hen filling the coolant system the coolant pump must be operating but one must ensure that the compressor and the heat transfer pump cannot start. The coolant pump can then be run manually using a separate switch which is located on the electrical cabinet.

W hen filling is complete the coolant pump must be put in Auto mode.

T he appliance is intended to be used by expert or trained users in shops, in light industry and on farms or commercial use by lay persons

Only spare parts approved by us may be used in this appliance.

The power supply must be disconnected during

service and before changing parts in the appliance.

1 .1 Refrigerant

The heat pump’s cooling system (refrigerant circuit) is filled with R407C or R134a (depending on version) refrigerant.

Work on the refrigerant circuit must only be carried out by a certified engineer!

Toxicity

In normal use and normal conditions the refrigerant has low toxicity. However. although the toxicity of the refrigerant is low. it can cause injury (or be highly dangerous) in abnormal circumstances or where deliberately abused.

The refrigerant vapour is many times heavier than air and in enclosed spaces. below the level of the door for example. and in the event of leakage. large concentrations can occur with the risk of suffocation because of lack of oxygen. Spaces in which heavy vapour can collect below the level of the air must therefore be well ventilated.

Refrigerant exposed to a naked flame creates a poisonous irritating gas. This gas can be detected by its odour even at concentrations below its permitted levels. Evacuate the area until it has been sufficiently ventilated.

Anyone with symptoms of poisoning from the vapour must immediately move or be moved into the fresh air.

Work on the refrigerant circuit

When repairing the refrigerant circuit. the refrigerant must not be released from the heat pump – it must be destroyed at a special plant. Draining and refilling must only be carried out using new refrigerant (for the amount of refrigerant see manufacturer’s plate) through the service valves. All warranties from Danfoss Heat Pump´s AB are void if. when filling with refrigerant other than R407C or R134a. it has not been notified in writing that the new refrigerant is an approved replacement refrigerant together with other remedies.

Scrapping

When the heat pump is to be scrapped the refrigerant must be extracted for destruction. The local regulations for treatment of refrigerant must be followed. See the relevant Swedish Environmental Protection Agency refrigerant statutes.

1 .2 Noise and vibrations

From the sound and vibration point of view it is important that the pipe mountings in the ceiling and walls are made with vibration damping fastenings and that the holes for lead-ins in the walls are made as large as possible so that sound and vibration do not spread.

If the house has poor acoustics. special care must be taken so that the vibrations do not spread into the building.

In such cases no mountings may be made in the house near the heat pump. All mountings must be in free standing constructions. which themselves are in vibration damping material such as Solodyn.

In those cases where the coolant side must be mounted to the building. flexible hoses should be used. although not the same type as the heat transfer pipes. Flexible hoses for the heat transfer and hot gas must be extra long (600 mm or longer) and connected at 90°. If one suspects that the floor on which the heat pump is located may transfer vibration to the rest of the building. the heat pump must be positioned on Solodyn pads. These pads must be weight adapted. Always consult the representative from Danfoss Heat pump´s AB in these cases.

VMIFI102 5

1.3 Electrical connection

The electrical installation must only be carried out by an authorized electrician (and must follow applicable local and national regulations). The electrical installation must be carried out using permanently routed cables. It must be possible to isolate the power supply using an all-pole circuit breaker for the intended current. For information regarding maximum load for externally connected devices, see electrical installation instructions.

NOTE! The supplied language specific decal for electrical connection must be adhered to the inside of the door

13 Stop both the pumps and immediately close valve 1 and 2.

14 Open valve 3 and disconnect the filling hoses.

15 Open valve 6 and pressurise the system, and vent via valve 1. Pressurise to max 1.5 bar.

16 Close valve 6.

17 Set switch S1 and S2 to Auto

(compressor and brine pump).

18 Clean the strainers after filling.

8 Start up

The installation may only start operation if the heating system, any hot water tanks and the coolant circuit are filled. Otherwise the pumps can be damaged.

In addition, the following points must be checked before starting operations:

• Check the rotation direction of the coolant pump. This is most easily done by setting switch S2 to manual. There is an indicator lamp, under the cover of the coolant pump connection terminal box, which lights when the rotation direction is correct.

• Check that all connections are sealed.

• Check the compressor’s direction of rotation by start ing the compressor and feel by hand if the pressure line

(upper pipe) is warm and the suction line (lower pipe) is cold.

• If this is not the case, two of the phases in the power supply must be switched (for example L1 and L3).

• Adapt the factory settings to the customer require ments.

10 Troubleshooting

Alarm

In the event of an error message try restarting the installation using the reset button on the control panel.

If restarting the heat pump does not help try rectifying the problem using the table below.

Message

LOW PRESS

ERROR

HIGH PRESS

ERROR

MOTOR P

ERROR

Meaning

Low pressure error - The compressor stops and there is no hot water production.

High pressure error - The compressor stops and there is no hot water production.

Cause

Not enough anti-freeze in the coolant system. Air in the brine system. Blocked filter in the brine system.

Coolant pump has stopped or is running at slow speed.

Ice build up in the coolant system.

Underfilled cooling system or any leaks.

Blocked or filled drying filter in the cooling circuit.

Insufficiently opened radiator/ floor loop thermostats. Air in the heating system. Blocked strainer in the heating system, located in the heat pump return.

Overfilled refrigerant circuit.

Remedy

Fill the refrigerant with the correct percentage of anti-freeze and bleed using the safety valve on the volume container. Check if the strainer needs cleaning.

Take temperature difference readings between incoming and outgoing coolant. The difference should be between approximately

3-5°C.

Measure the amount of anti-freeze in %, wait until the ice melts, which affects the low pressure switch not contacting the wiring.

Drain and leak trace as well as filling new refrigerant. No refilling of drained medium.

Measure the temperature difference of the filter – max 2°C.

Open radiator / floor loop thermostats. Fill and bleed the heating system. Measure delta over the heat pump supply and return lines.

Temperature difference.

Draining the refrigerant circuit and refilling with new refrigerant, according to the instructions.

Check the heart transfer fluid pump.

Heat transfer fluid pump has stopped or is running at slow speed.

Phase drop or blown fuse.

Motor protection error - (Over current relay compressor or brine pump).

The compressor stops and there is no hot water production.

Poorly tightened electrical connections.

Too low network voltage.

Check the fuses and cable terminals

(power supply to the compressor or brine pump).

Check the electrical connections.

Measure the voltage to the heat pump’s electrical connection.

Other alarms;

See separate manual for the control system.
