INSTALLATION

CHOICE OF INSTALLATION SITE

Before installing the unit, agree with the customer the site where it will be installed, taking the following points into consideration:

- check that the fixing points are adequate to support the weight of the unit;

- pay scrupulous respect to safety distances between the unit and other equipment or structures to ensure that air entering the unit and discharged by the fans is free to circulate.

- Follow the instructions shown in the chapter on DIMENSIONAL DRAWINGS to allow room for maintenance operations. If installing multiple units the clearances must be doubled.

POSITIONING

Before handling the unit, check the capacity of the lift equipment used, respecting the instructions on the packaging. To move the unit horizontally, make appropriate use of a lift truck or similar, bearing in mind the weight distribution of the unit. To lift the unit, insert tubes long enough to allow positioning of the lifting slings and safety pins in the special holes in the base of the unit. To avoid the slings damaging the unit, place protection between the slings and the unit.

The unit should be installed on special vibration dampers. See the chapter on DIMENSIONAL DRAWINGS for the support positions identified by W1, W2 etc. and the corresponding weights for the correct sizing of the vibration dampers. Fix the unit, making sure it is level and that there is easy access to water and electrical components. If the site is exposed to strong winds, fix the unit adequately using tie rods if necessary. In heating mode the unit produces a significant quantity of condensate, which must be suitably drained. Condensate drainage must not cause problems to objects or people. If the outside air temperature is less than 0°C, the condensate may freeze; in these case fit a frost protection heater on the drain line. For correct operation of the unit, avoid the following: obstacles to air flow, leaves that may block the heat exchange coil, strong winds that stop or reinforce air flow, sources of heat too close to the unit, recirculation or stratification of air.

WATER CONNECTIONS

I A

The choice and installation of components is the responsibility of the installer who should follow good working practice and current legislation. Before connecting the pipes, make sure they do not contain stones, sand, rust, dross or other foreign bodies which might damage the system. Construction of a bypass is recommended to enable the pipes to be washed through without having to disconnect the unit (see drain valves). The connection piping should be supported in such a way as to avoid it weighing on the unit. The following components should be installed in the water circuit:

1. Two pressure gauges with a suitable scale (intake and outlet);

2. Two vibration damper joints (intake and outlet);

3. Two gate valves (normal in intake and calibrating in outlet);

4. A flow switch (inlet). The flow switch must be cali-

brated by the installer to a value equal to 70% of rated flow.

5. Two thermometers (intake and outlet);

6. An intake filter must be installed as close as possi-

ble to the unit and positioned to allow easy access for routine maintenance.

7. All the pipes must be insulated with suitable material to prevent the formation of condensate and heat loss. The insulating material must be a vapour barrier. Make sure that the control and shut off devices protrude from the insulation.

8. At the lowest points in the system, install drain valves for easy emptying.

9. At the highest points in the system, install automatic or manual air vent valves.

10. The unit is fitted as standard with an expansion vessel; make sure this is correctly sized for the water content of the system and the expected operating temperature, otherwise install an additional expansion vessel.

La mancata installazione dei flussostati non assicura una Failure to install the flow switches will mean the heat exchangers are not protected in the event of no flow of liquid. Climaveneta cannot be held liable for any damage to the unit and/or the system following the failure to install these devices or the filter. The correct operation of the components that help ensure the safety of the appliance and the system should be checked regularly. Specifically, this involves cleaning the filters and checking the operation of the flow switches installed. Make sure that the frost protection heaters on the heat exchanger are powered when the unit is off (unit in standby “StbY”) Water flow to the chiller unit must conform to the values shown in the section on “General Technical Data”. The flow of water must be maintained constant during operation. The water content of the unit must be such as to avoid disturbing operation of the refrigerant circuits.

The unit must be prevented from freezing at outside air temperatures around 0°C. It is recommended to use suitable percentages of antifreeze (see “Water circuit data”), protect the piping with heating sheaths, and empty the system, making sure there no water remains at the lowest points in the circuit. It is recommended to use non-toxic food grade antifreeze, compliant with the standards in force in the countries where the unit is used, if domestic hot water production is also featured.

FILLING THE SYSTEM

- Before starting to fill, place the unit mains switch QF1 in the OFF position.

- Before filling, check that the system drain valve is closed.

- Open all system and terminal air vents.

- Open system shut off valves.

- Start filling by slowly opening the system water fill valve outside the unit.

- When water begins to leak out of the terminal air vent valves, close them and continue filling until the pressure gauge indicates a pressure of 1.5 bars.

The system must be filled to a pressure of between 1 and 2 bars. It is recommended that this operation be repeated after the unit has been operating for a number of hours. The pressure should be checked regularly and if it drops below 1 bar, the water content should be topped-up.

Check the tightness of the joints.

EMPTYING THE SYSTEM

- Before starting to empty, place switch QF1 in the OFF position

- Make sure the system fill/top-up water valve is closed.

- Open the drain cock outside the unit and all the installation and terminal air vent valves..

If the fluid in the circuit contains antifreeze, it should not be allowed to drain freely, as it is pollutant. It should be collected for possible reuse. When draining after heat pump operation, take care as the water may be hot (up to 50°).

TEMPERATURE CONTROL

The water outlet temperature to the heating circuit is calculated by the controller based on the following factors:

• slope of the heating curve (see paragraph)

• comfort set point in relation to the room temperature (see the corresponding paragraph)

• reduced set point in relation to the room temperature (see the corresponding paragraph)

• influence of the room temperature (see the corresponding paragraph)

• minimum and maximum limit outlet temperature set point (see the corresponding paragraph)

To display the calculated outlet temperature set point press the info button , and turn the knob until displaying “Flow temp setpoint 1”.

COMPRESSOR START UP DELAY

To prevent the compressor from starting up too frequently the minimum time since last shut-down is 5 minutes.

CIRCULATING PUMP

The electronic board has an output for managing the circulating pump. The circulating pump is stopped, after a few minutes, when reaching the room set point plus 0.5°C. After the first few seconds of pump operation when the water flow is at full speed, the water flow alarm functions are activated (flow switch). In protection mode the circulating pump is off.

INFLUENCE OF THE ROOM TEMPERATURE

Parameter

number

Description

The room unit is fitted with a sensor for measuring the room temperature. Parameter 750 is used to select the influence of the room temperature on the calculation of the heating curve. a 750= - - - % the room temperature is not used for the calculation of the heating curve.

The outlet temperature is calculated by the heating curve based solely on the outside temperature.

b) 750= 100% the outlet temperature is calculated based on the room temperature set point.

The outside air temperature has no influence. A slight increase in the room temperature brings an immediate decrease in the outlet temperature.

c) 750= 1…99% The value of the room temperature is used in the calculation of the outlet temperature.

The heating curve selected by parameter 720 will be shifted along an axis in parallel and consequently the outlet temperature will be different The better the reference room temperature (suitable choice of the room and positioning of the room unit), the more readily the room temperature will be satisfied. Example:

- If a value of around 60 % is selected for parameter 750, this indicates a reference room temperature and good positioning of the room unit.

- If a value of around 20 % is selected for parameter 750, this indicates a less-than-perfect reference room temperature and poor positioning of the room unit.

For settings b) and c) there must not be thermostatic valves in the reference room (the same where the room unit is located). If these are present, they must be opened completely.

Parameter

number

Description

The heating curve compares the outside temperature and the water outlet temperature fort heating. The slope can be modified to allow correct operation of the heat pump based on the type of heating circuit (radiant panels, radiators etc.).

Example: Selecting heating curve 1.5, with an outside air temperature of -5°C, gives a water outlet temperature of +55°C. To display the calculated outlet temperature set point, press the info button, then turn the knob until displaying “outlet set point 1”. Select the desired slope of the heating curve using parameter 720. A heating curve that is too high means an excessive outlet temperature, a curve that is too low may mean the desired room temperature is not reached.

ACCELERATED HEATING

Parameter

number

Description

Accelerated heating is used to switch over more rapidly from the reduced set point to the Comfort set point, reaching a new set point (Comfort set point + the value parameter of 770). In this way, the heating operating time is reduced. During accelerated heating, the room temperature set point is increased to the value set for parameter 770. The higher this value, the lower the heating time; the lower the value, the longer the heating time.

Accelerated heating is only active when switching from the reduced set point to the Comfort set point. To activate the function, set a value from 0 to 20°C.

Description

Accelerated shut-down is used to switch over more rapidly from the Comfort set point to the reduced set point, keeping the heat pump off.

The function keeps the heating system off until the room temperature reaches the reduced set point or the frost protection set point. When reaching one of these set points, the pump and/or the mixer valve in the heating circuit are reactivated.

During the accelerated shut-down phase, the pump in the heating circuit is not operating while, in the case of circuits with radiant panels, the mixer valve is completely closed.

HEAT PUMP OPERATION WITH FIXED SET POINT

Parameter

number

Description

Digital input SA6 allows operation of the heat pump with a fixed outlet set point, defined by parameter 5952. Closing the contact disables the outside temperature probe and the room unit.

This is used to select the water outlet temperature set point.

Default setting

5950 = Minimum flow temperature set point

5952=50°C

FROST PROTECTION

Frost protection for system water temperature

The frost protection function is always active, even when the heat pump is off. If the outlet temperature falls below 5 degrees, the compressor and the heating circuit pump are activated, irrespective of the operating mode. When the outlet temperature rises back above of 7°C, the controller waits a further 5 minutes and then stops the production of heat and pumps.

Frost protection for room temperature

The frost protection function is always active, even when the heat pump is off. If the inside room temperature falls below 8°C (value set for parameter 714), the heat pump is started to prevent freezing in the pipes inside the home.

Frost protection for outside temperature

The frost protection function is always active, even when the heat pump is off. The pump is activated according to the outside temperature, as shown in the following graph:

ROUTINE MAINTENANCE

Never perform any cleaning operations before having

disconnected the unit from the mains power supply. Make sure power is not connected before proceeding. Control maintenance is fundamental to maintain the efficiency of the unit both in terms of operation and energy consumption. The Technical Service maintenance plan must be observed, with an annual service which includes the following operations and checks:

- Filling of the water circuit;

- Presence of air bubbles in the water circuit;

- Efficiency of safety devices;

- Power supply voltage;

- Electrical power input;

- Tightness of electrical and water connections;

- Condition of the compressor contactor;

- Efficiency of the plate heat exchanger resistor;

- Verification of operating pressure, superheating and subcooling

- Efficiency of the compressor heater

- Cleaning of the finned coil every three months

- Cleaning of the fan grills

- Cleaning of condensate drain pan (if installed);

For units installed near the sea, the intervals between maintenance should be halved.

SHUTTING DOWN FOR LONG PERIODS

After deactivating the heat pump:

- Disconnect the unit from the power supply.

- Make sure the remote keypad (if featured) is in the “OFF” position.

- Place QF1 in the OFF position (see wiring diagram).

- Deactivate the indoor terminal units by placing the switch of each unit in the “OFF” position.

- Close the water valves.

If the outside temperature may fall below zero; there is the risk of freezing. The water circuit MUST BE EMPTIED AND CLOSED (if draining after operation in heat pump mode, beware that

the water may be hot), or antifreeze must be added in the proportion recommended by the manufacturer. It is recommended to use non-toxic food grade antifreeze, compliant with the standards in force in the countries where the unit is used, if domestic hot water production is also featured. If the mains switch is turned to “off” for more than four hours, after turning it on and before reactivating the unit, leave the power on but the unit deactivated for at least two hours to preheat the oil in the compressor sump.

53GB 05/2009 AW HT

SPECIAL MAINTENANCE

Never perform any cleaning operations before having

disconnected the unit from the mains power supply. Make sure power is not connected before proceeding.

REFRIGERANT GAS CHARGE

It is recommended to chemically flush the plate heat exchanger after every 3 years of operation. For instructions on how to carry out this operation, call the toll free number.

REFRIGERANT GAS CHARGE

The chillers are filled with R410A refrigerant gas and tested in the factory. In normal conditions, there should be no need for the Technical Service to intervene to check the refrigerant gas. However, over time, small leaks may develop at the joints leading to loss of refrigerant and draining of the circuit, causing the unit to function poorly. In this case, the leaks of refrigerant must be identified and repaired and the refrigerant circuit recharged. Proceed as follows:

- Empty and dry the entire refrigerant circuit using a vacuum pump connected to the low and high pressure tap until the vacuometer reads about 10 Pa. Wait a couple of minutes and check that this value does not rise to more than 50 Pa.

- Connect the refrigerant gas cylinder or a filling cylinder to the low pressure line pressure gauge connection

- Charge the quantity of refrigerant indicated on the unit’s rating plate.

- Always check the superheating and subcooling values, which should be between 5 and 10°C and 4 and 8°C.

- After a couple of hours operation, check that the liquid indicator indicates a dry circuit (dry-green).

In the event of partial leaks, the circuit must be completely emptied before being recharged. The R407C refrigerant must only be charged in the liquid state. Operating conditions other than rated conditions may produce considerably different values. Tightness testing or identification of leaks must only be carried out using R407C refrigerant gas, checking with a suitable leak detector. The refrigerant circuit must not be charged with a refrigerant other than that indicated on page 16. The use of a different refrigerant may cause serious damage to the compressor.

Oxygen, acetylene or other flammable or poisonous gases must never be used in the refrigerant circuit as they may cause explosion or poisoning. Oils other than those indicated on page 16 must not be used. The use of different oil may cause serious damage to the compressor.

DISPOSAL

The unit must be disposed of according to the legislation

in force in the country concerned
