3.3 Operating principle

The thermodynamic DHW tank uses unheated ambient air or outside air to prepare DHW.

The refrigerant circuit is a closed circuit in which the R-134a refrigerant plays the role of an energy carrier.

The heat from the intake air is transferred to the refrigerant in the finned heat exchanger at a low evaporation temperature.

The refrigerant is sucked in by a compressor in vapour form, which raises it to a higher pressure and temperature and sends it to the condenser. In the condenser, the heat extracted in the evaporator and some of the energy absorbed by the compressor are released into the water.

TWH 200E TWH 300E TWH 300EH 3. Technical description

The refrigerant is depressurised in the thermostatic expansion valve and is cooled. The refrigerant can again extract the heat contained in the inlet air into the evaporator.

4.5.3. Levelling

To improve condensates evacuation, we recommend tilting the appliance slightly backwards.

1. Level the appliance using the adjustable feet.

(1) Adjustable feet, Basic dimension 4 mm Can be adjusted from 4 mm to 21 mm

CAUTION

Before making the hydraulic connections, it is essential to rinse the circuit to get rid of any particles that may damage certain units (safety valve, pumps, valves, etc.). If rinsing has to be done using an aggressive product, neutralise the rinsing water before disposing of it in the waste water network.

Using hoses which are too short or too rigid encourages the transmission of vibrations and the production of noises.

Version EH: Make all the hydraulic connections for the DHW tank using flexible pipes.

4.6.1. Connecting the calorifer to the domestic water circuit (secondary circuit)

When making the connections, it is imperative that the standards and corresponding local directives are respected.

Specific precautions

Before making the connection, rinse the drinking water inlet

pipes in order not to introduce metal or other particles into the appliance’s tank.

03/02/2014 - 300026515-001-03

TWH 200E TWH 300E TWH 300EH

4. Installation

CAUTION

Do not connect the domestic hot water connection directly to copper pipes in order to prevent galvanic couples in iron/ copper (risk of corrosion). It is compulsory to fit the domestic hot water connection with a dielectric connection (Supplied).

Safety valve or safety unit

CAUTION

In accordance with safety rules, a safety unit calibrated to 7 bar must be mounted on the DHW tank’s domestic cold water inlet.

4 Integrate the safety valve in the cold water circuit.

4 Install the safety valve close to the calorifer in a place which is

easy to access.

Size

4 The diameter of the safety unit and its connection to the calorifer

must be at least equal to the diameter of the domestic cold water inlet on the calorifer.

4 There must be no cut-off element between the valve or the safety

unit and the domestic hot water calorifer.

4 The outlet pipe in the valve or safety assembly must not be

blocked.

To avoid restricting the flow of water in the event of overpressure:

4 The safety device drain pipe must have a uniform and sufficient

gradient and its diameter must be at least equal to that of the outlet opening of the safety device (to prevent the flow of water being hindered if the pressure is too high).

4 The cross section of the discharge pipe from the safety unit must

be at least equal to the cross section of the opening of the safety unit outlet.

Isolating valves

03/02/2014 - 300026515-001-03

Hydraulically isolate the primary and secondary circuits using stop valves to facilitate maintenance operations on the unit. The valves make it possible to carry out maintenance on the calorifer and its components without draining the entire installation.

These valves are also used to isolate the calorifer unit when conducting a pressurised check on the leak tightness of the installation if the test pressure is greater than the admissible operating pressure.

4. Installation TWH 200E TWH 300E TWH 300EH

CAUTION

If the mains pipes are made of copper, fit a sleeve made of steel, cast iron or any other insulating material between the tank’s hot water outlet and the pipes to prevent corrosion to the connection.

Connecting the domestic cold water

Make the connection to the cold water supply according to the hydraulic installation diagram. Install a water drain in the boiler room and a funnel-siphon for the safety unit.

The components used for the connection to the cold water supply must comply with the prevailing standards and regulations in the country concerned. Fit a one-way valve to the domestic cold water circuit.

Pressure reducer

If the mains pressure exceeds 80% of the calibration of the valve or safety unit (e.g. 5,5 bar (0,55 MPa) for a safety unit calibrated to 7 bar (0,7 MPa)), a pressure reducer must be installed upstream of the appliance. Install the pressure reducer downstream the water meter in such a way as to ensure the same pressure in all of the installation pipes.

Measures to take to prevent hot water flow return

Fit a one-way valve to the domestic cold water circuit.

4.6.2. Connection to a boiler (Version EH)

CAUTION

Before making the water connections of the heating circuit and domestic hot water tank heat exchanger, it is imperative to rinse the circuits to remove any particles which might damage the components (safety valve, pumps, valves, ...).

7 Checking and maintenance

7.1 General instructions

CAUTION

Installation and maintenance of the appliance must be done by a qualified professional in accordance with prevailing statutory texts and codes of practice.

CAUTION

Before working on the appliance, ensure that it is switched off and safe.

CAUTION

Check the discharge on the compressor condenser for single phase voltages.

CAUTION

Before working on the cooling circuit, switch off the appliance and wait a few minutes. Some equipment such as the compressor and the pipes can reach temperatures higher than 100°C and high pressures, which may cause serious burns.

When the appliance is switched off, the fan continues to run by inertia for around one minute.

Maintenance operations are important for the following reasons:

4 To guarantee optimum performance

4 To extend the life of the equipment

4 To provide an installation which offers the customer optimum

comfort over time.

CAUTION

At no time allow water to get into the control components. Before starting cleaning, disconnect the mains power plug or switch off the appliance.

7.2.1. Refrigerant circuit

No maintenance is required on the refrigerant circuit in the thermodynamic water heater.

7.2.2. Hydraulic circuit

Check the watertightness of the water connections.

7.2.3. Aeraulics

Cleaning the evaporator

7. Checking and maintenance

DANGER

Risk of injury on the sharp-edged fins.

CAUTION

Do not distort or damage the fins.

4 Clean the evaporator at regular intervals using a soft-haired brush.

4 Carefully realign the fins using a suitable comb if they are bent.

Cleaning the fan

Check the cleanliness of the fan 1 time per year. Clogging by dust and other particles impairs the heat pump’s performance.

7.2.4. Impressed current anode

No maintenance operations are required on an impressed current anode.

The appliance’s control panel must be switched on to ensure operation of the impressed current anode.

03/02/2014 - 300026515-001-03

7.2.5. Checking the safety valve or unit

Operate the safety valve or unit at least 1 time per month to check that it is running correctly. This check provides forewarning of any occurrences of excess pressure that may damage the domestic hot water calorifier.

7. Checking and maintenance TWH 200E TWH 300E TWH 300EH

WARNING

Failure to comply with this maintenance rule may cause deterioration of the DHW tank and the cancellation of the guarantee.

7.2.6. Descaling

Use a new leak tight seal on the inspection trap.

In hard water regions, it is advisable to ask the fitter to descale the DHW tank exchanger once a year in order to maintain its level of performance.

1. Turn off the domestic cold water inlet.

2. Drain the calorifier.

3. Open a hot water tap.

4. Open the valve on the safety unit.

5. Remove the insulation from the inspection hatch.

6. Pull out the DHW sensor.

7. Remove the inspection trap (13 mm spanner).

8. Remove the 2 bulbs from the safety thermostat.

9. Remove the limescale deposited in the tank in the form of sludge

or strips. Keep the limescale on the wall of the tank: it provides effective protection against corrosion and enhances the insulation of the DHW tank.

10.Then replace all the parts in reverse order.

Each time it is opened, the lip gasket must be replaced to guarantee tightness. Place the positioning lug on the gasket toward the outside of the tank.

11.After each intervention, ensure that the installation is watertight.

The screws retaining the visit trap must be tightened to 6 N·m +1/-0. Use a torque wrench.

7.2.7. Cleaning the condensates discharge duct

Check the cleanliness of the condensates discharge pipe. An obstruction by dust may cause poor condensates flow or even a risk of excessive accumulation of water.

DANGER

Risk of the heat pump malfunctioning.
