7 - AERAULIC CONNECTIONS

7.1 AERAULIC DESIGN CRITERIA

The dimensioning and the correct execution of the aeraulic connections are critical to ensure the unit operating and an appropriate level of quietness in the served area.

Pressure loss in the duct will reduce the air flow, which can cause a reduction in efficiency of the unit. The maximum static pressure should be within 25Pa

7.2 AIR DUCT CONNECTION

If the duct outlets for the outdoor air inlet and exhaust are outside of coverage, must end with a 90 ° bend downward, to prevent entry of water from the air inlet. To perform the ductings:

x Connect the ductings fixing them to the connections with

the special hookings to the circular flanges.

x The duct weight should not lie on the connection flanges. x Put antivibration joints between ducts and units. x The connection to the flanges and among the different

duct sections must guarantee the air seal, avoiding air

dispersions in supply and return that penalize the overall

efficiency of the installation.

x Limit the pressure drops by optimizing the path, the type

and the number of curves and branches.

x Use curves of large radius. x For unit air outlet with duct, when unit operating,

condensate will be generated aroud outside of duct.

x Thermically insulate the supply ducts to avoid heat losses

and condensate.

Avoid recirculation of exhaust/return air Use elbows with a 90° downward bend

In terms of the unit connect with duct reaching to outdoor, a reliable water-resistant measure must be conduct on the duct, to prevent water from dropping into internal of the unit .

In case the water entering to internal components of the unit, the component might be damaged or causing physical danger.

The ducts should not be tilted towards unit to avoid the condensate and water return.

7 - AERAULIC CONNECTIONS

Aeraulic Connections

The unit must be installed inside the building, preferably in a technical room or a laundry room or a garage. At any rate, it is always preferable to avoid installing the unit near bedrooms or in rooms that must be protected from noise. Outdoor installation is prohibited, as well as installation in places subject to external weather. Examples below refer to the 190 version. For the 300 version, the expulsion and intake connections are inverted.

INTAKE AND EXPULSION DUCTS (recommended)

Channelling the intake and expulsion through ducts allows the unit to function with air taken from outside the house. Heat is extracted from the outdoor air, and used as a source for the heat pump. Later this same air is expelled outside the building. Therefore, unit operation does not cause an increase in heating requirements in the home. It is necessary to fit the system with correctly sized pipes in relation to the available pressure head supplied by the unit.

INTAKE DUCTS (conditioned)

Installation with an intake duct and free expulsion is recommended if there is a desire to use the air expelled by the unit, cold dehumidified air (5-10°C colder than the intake air), to cool the room. The unit must be installed preferably in a room that does not require heating, because the unit releases cold air into the environment and it would increase the cost of heating that room. The unit must be installed in a room with a minimum volume greater than 15m

. The expulsion air flow must be guaranteed and cannot be blocked. It is necessary that the vents be correctly sized.

EXPULSION DUCTS (conditioned)

In this particular type of installation, the unit takes in air from the room where it is installed, extracts the heat and then expels that air outside the house. The unit must be installed in a room with suitable openings to allow the correct flow of air into the unit, which would prevent the air pressure in the room from falling. The unit must be installed in a room with a minimum volume greater than 15m

2) Water Temperature Display The temperature shown on the display depends on the upper sensor. So it is normal that the display temperature has reached to target temperature but compressor still running, because the lower water temperature does not get to target temperature. Modes will be automatically selected by unit. manually mode selection is unavailable.

Storage tank

Page 32

9 - START-UP

3) Heat source will be automatically selected by unit. But manually E-Heater operation is available.

4) Heat Source Shift The default heating source is heat pump.

If externalis range out of heat pump, heat pump will stop running, the unit will shift automatically to activate E-heater and show the icon LA on the display, then if the externaltemperature goes into the running range of heat pump again, it will stop E-heater and shift automatically to heat pump again, and the icon LA will be extinguished.

If the target setting water temperature is higher than Max. temp(Heat pump), the unit will activate heat pump firstly to the Max. temperature, then stop heat pump, activate Eheater to continually heat water to the target temperature.

If manually activate the E-heater running mode when heat pump running, E-heater and heat pump will work together until the water temperature gets to target temperature. So if want to heat quickly, please manually activate Eheater.

NOTE

E-heater will be activated once for the current heating progress, if want to apply E-heater again please push E-HEATER.

About TCO and ATCO The power of compressor and E-heater will be automatically

shut-off or turn on by TCO and ATCO. If the water temperature is higher than 78°C, the ATCO will

automatically shut off the power of compressor and E-heater, and reconnect it if the temperature falls down below 68°C.

If the water temperature is higher than 85°C, the TCO will automatically shut off the power of compressor and E-heater.

After that it needs to be reset manually by pressing the red button on the TCO.

Notes

While the external temperature below than -7°C, heat pump efficiency will decrease dramatically, the unit will automatically shift to E-heater mode.

If system occurs some malfunctions, error code "E7" and will be shown on the display, then heat pump will stop running, and the unit will activate automatically E-heater as the backup heat source, but the code "E7" and will be shown until power off.

If only use E-heater, about only 75 liters water (unit 190) will be heated or about only 150 liters water (unit 300), so must set higher target water temperature if externaltemperature is out of heat pump running range.

Defrosting During Water-heating In heat pump running period, if the evaporator frosted in lower ambient temperature, the system will defrost automatically to keep effective performance(about 3~10min). At defrosting time, the fan motor will stop, but compressor will still run.

10.9 NON-ERROR TIPS

Q: Why compressor can't start immediately after setting? A: Unit will wait for 3 min to balance the pressure of system before start compressor again, it's a self protection logic of unit.

Q: Why sometimes the temperature shown on the display panel decreased while unit is running? A: R. When hot water is sampled, it is mixed with cold water which is added from the low part of the accumulator.

Q:Why sometimes the temperature shown on the display decreased but unit still keep closed? A: To avoid unit ON/OFF frequently, unit will activate heat source only when bottom storage tank temperature is lower than setting

temperature for at least 6ºC.

Q:Why sometimes the temperature shown on the display will decreased dramatically? A: Because storage tank is pressure-bearable type, if there is massive hot demand, hot water will quickly tapped out from upper part of

storage tank as well as cold water will quickly tapped into bottom part of bank, if the cold water surface emerge the upper temperature sensor, temperature shown on the display will decreased dramatically.

Q: Why sometimes the temperature shown on the display is decreased a lot, but there is still a mount of hot water can be tapped? A: Because the upper water sensor is located on the upper 1/4 storage tank, when tapping hot water out, it means there is at least 1/4

storage tank of hot water available.

Q: Why sometimes unit shows "LA" on display ? A: The heat pump available running externalrange is -7 ~ 43°C, if externaltemperature is out of range, system will show

abovementioned signal to let user notice it.

Q: Why something there is nothing shown on the display? A: To maintain display screen lifespan within along term, when there is no button operation for 30 sec, it will extinguish the display

except the LED indicator.

Q: Why sometimes the buttons are unavailable? A: If there is no operation on panel for 1 min, unit will lock the panel, shows "

for 3 seconds.

Q: Why sometimes there is some water flowed from drainage pipe of saftey valve? A: Because the storage tank is pressure-bearable one, when water is heated inside the storage tank, water will expand, so the

pressure inside of tank will increase, if pressure goes up more than 7Bar (0,7Mpa), saftey valve will activate to relief the pressure and hot water drop will be discharged correspondingly. If water drop is continually discharged from saftey valve drainage pipe, it is abnormal, please contact qualified stuff to repair.

8 Checking for leaks* Every year Check

*Refer to the local provisions for implementation; in an extremely brief and purely indicative manner, the regulation specifies the following. Companies and technicians carrying out installation, maintenance/repair interventions, checks for losses and recovery operations must be CERTIFIED in accordance with the local regulations. The check for losses must be carried out an an annual basis.

Check the connection between power supply plug and socket and ground wiring regularly;

The missing or lacking maintenance of the magnesium anode, can lead to the corrosion of the storage tank with a subsequent loss of water and the warranty coverage and the manufacturer responsibility fall.

It is recommended to clean the inner storage storage tank and e-heater to keep an efficient performance.

It is recommended to set a lower temperature to decrease the heat release, prevent scale and save energy if the outlet water volume is sufficient.

Clean the air filter every month in case of any inefficiency on the heating performance.

Notes/interventions suggested to the owner

11 - MAINTENANCE

11.2 GENERAL

Maintenance must be done by authorized centres or by qualified personnel

The maintenance allows to:

x maintain the unit efficiency x reduce the deterioration speed to whom every equipment

is subject over time

x assemble information and data to understand the state of

the unit efficiency and avoid possible damages

Before checking, please verify the following:

x the electrical power supply line should be isolated at the

beginning

x the unit isolator is open, locked and equipped with the

suitable warning

x make sure no tension is present

After turning off the power, wait at least 5 minutes before accessing to the electrical panel or any other electrical component.

Before accessing check with a multimeter that there are no residual stresses.

11.3 INSPECTIONS FREQUENCY

After a long term use, check the unit base and fittings. If damaged, the unit may sink and result in injury. Perform an inspection every 6 months minimum. The frequency, however, depends on the use. In the event of frequent use it is recommended to plan

inspections at close intervals:

x frequent use (continuous or very intermittent use, near the

operating limits, etc)

x critical use (service necessary).

11.4 UNIT BOOKLET

It’s advisable to create a unit booklet to take notes of the unit interventions.

In this way it will be easier to adequately note the various interventions and aid any troubleshooting.

Report on the booklet:

x data x type of intervention effected x intervention description x carried out measures etc.

11.5 PUT AT REST

In some cold areas (under 0°C), if the system will be stopped for a long time, empty the storage storage tank in order to avoid the water freezing and damage of E-heater.

If a long period of inactivity is foreseen:

x put the unit in OF F x wait a few minutes to allow all the actuators to reach the

rest position

x Turn off the power in order to avoid electrical risks or

damages by lightning strikes

x Evacuate all the water storage storage tank and the

pipeline and close all the valves; It’s recommended that the starting-up after the stopping period is performed by a qualified technician, especially after seasonal stops or seasonal switch. When restarting, refer to what is indicated in the START-UP section. Schedule technical assistance in advance to avoid hitches and to guarantee that the system can be used when required.

11.6 COIL

Accidental contact with the exchanger flaps can cause injuries from cut: use protective gloves.

The coil must allow maximum thermal exchange, therefore, the surface must be clear from dirt and scaling.

Clean the air inlet side. Use a soft brush or aspirator. Check the aluminium flaps have not been damaged or folded,

otherwise will be from "comb" the coil for excellent air flow. ( contact an authorised after-sales assistance centre )

11.7 STRUCTURE

Check the condition of the structure parts . Paint so as to eliminate or reduce oxidation where needed. Check that the paneling is correctly fastened. Poor fastening

may give rise to malfunctions and abnormal noise and vibration .

11.8 SAFETY VALVE

The safety valves must be checked regularly. Almost all losses are caused by impurities deposited inside

the valve. It’s normal if some water drops from the hole of saftey valve

during operation. But, if there is a great amount of water, call your service

agent for instructions. Please beware of burn, beware of the hot water from the

valve. To clean the valve:

1. Manually open the valve

2. Turn the knob as indicated by the arrow on the knob itself

Page 47

11 - MAINTENANCE

11.9 EXPANSION TANK

Check the expansion vessel charge (at least once a year). First check that the expansion vessel is totally drained of

water. If you necessary load with nitrogen, take care that the

pressure does not exceed the value indicated on the label.

11.10 ANODE ROD REPLANCE

The magnesium sacrificial anodes assure the storage tank anti-corrosive protection.

The magnesium anode is replaced when its diameter is  of a third of the original anode.
