Before consulting the tables, add secure drops to the pressure required for the installation due to:

• heat pump (models ARH/ARD-045 and 060)

• Gas heating (ARG/ARD Models)

• vertical supply and return and

• accessories included in the unit, when appropriate. See Pressure drop of options/accessories, gas

heating and vertical ducts. , see on page 21 .

The motor pulleys come adjusted to an opening of 4 turns. See

Maintenance tasks performed by spe‐

cialised personnel

, see on page 35

for the belt adjustment and tightening procedure.

C AU T I O N

• Before commissioning the installation, but after balancing the air distribution in the building, the supply air flow should be checked.

• With clean filters the indoor fan should not exceed a -200 Pa drop in intake.

1.15.1 Characteristics of the placement

The location of the unit must be studied to ensure a completely satisfactory installation. To do so, the environmental conditions of the area where the unit is to be installed must be taken into account.

Furthermore, the normal weather conditions should be instrumental in determining the best position of the unit and the hoods, screens or covers required to ensure its correct working order.

If possible, in warm zones like the southern Europe, the unit should be located on the north or east side of the building or property.

The location chosen for the unit must provide the condenser with an unlimited air supply.

As well as the technical data given in this document and any others that are applicable, please bear in mind that the unit has been designed for outdoors installation only.

Where the unit is to be installed at ground level, refer to section

Specifications for the foundation or

anchoring of the unit , see on page 23

Where the unit is to be installed on the roof of a building or property, make sure that the roof structure can support the weight of the unit plus that of any optional equipment and/or accessories to be fitted.

The unit must be installed on a specific mounting base or on a frame of appropriate steel angles. There are optional mounting bases available (Roof-curb).

Regardless, keep the level tolerance at maximum 10 mm all along the length and width of the unit.

If the unit is to be installed on a base or on a special angle frame that is not the standard Roof-curb, gaskets should be applied to all surfaces that are touching the bottom of the unit.

If it is preferred to place the unit on shock absorbers, this should be done as described in

for supply and return side ducts , see on page 10

Special instructions for locations where there is regular snowfall or with ambient temperatures of close to 0ºC or less

In areas where there is regular or sporadic snow, the unit should be elevated above the ground or roof where it is installed. The height should be enough to prevent the unit, the condenser and evaporator air inlets and the access to the unit panels from becoming blocked by accumulated snow.

Protection against ice

In areas where the temperature can be 0ºC or less, there should be some kind of additional protection to prevent the water contained in the condensate drain pipe from freezing.

Use an electric cord resistor in the drain trap as well as in the drain, where applicable.

In heat pumps, also use cord resistors in the outdoor coil tray to prevent any ice from accumulating.

Special instruction for locations with high ambient temperatures

In areas where the ambient temperature is over 43ºC, the unit must not be located in direct sunlight and, therefore a specific sunshade will be required.

The installation of a special sunshade over the unit must not effect the air flow required by the unit to work correctly. Check the minimum clearance required

Connections for supply and return side ducts ,

The length and width of the slab must be at least 150 mm more than the base rails on the unit.

C AU T I O N

Do not attach the unit to the foundations of the building.

1.15.4 Characteristics of utility provider connections

In general, the different connections required by the unit are made following the shortest route possible. Under no circumstances may any local or national regulations be contravened when performing the preparatory work for service connections.

N OT E

For further information on this subject, always keep the current regulations for the country where the unit is being installed at hand.

C AU T I O N

• Before the connection work, possible losses of flow, temperature and voltage drops, etc. that might affect the distances between planned connection points and the unit must be taken into account.

• As a result, each connection must be sized accordingly.

Additional specifications for the gas connection (for ARG/ARD models only)

To correctly size the gas supply pipe, keep in mind the flow required, the specific density of the gas and the length of the stretch.

The fact that the heating value of the gas can vary from town to town should also be kept in mind. The heating value of the gas should be checked with the utility company.

1.15.5 Preparation and connecting to the various utilities

Gas. Insulation and/or duct protection.

A specific line should be used for gas supply. Its installation must comply with country and local safety regulations.

A special grommet, kept in fan compartment, is pro‐ vided for the gas supply pipe, This grommet should be placed in the panel at the front of the unit at the time the gas supply pipe is installed.

Important recommendations for the installation of the gas supply pipe

1 If the supply line needs to carry gas when there is condensation, then a device for its collection and

discharge should be installed. -2-.

2 Install a manual gas supply shut-off valve -3- if required by the current regulations in the country the

unit is being installed in.

3 Install a ground in the gas supply line.

4 Use a wrought iron or steel pipe for the installation of the gas supply line.

5 Before installing the pipe hit the outside with a hammer to get rid of any dirt or scale it might have

inside. Use compressed air to expel any residue and particles that might be there.

6 Apply a moderate amount of sealing paste to the threads of the male part of the joint.

D AN G E R

• Natural gas may contain a small quantity of propane, which is an efficient solvent of lead carbonate and most common commercial compounds.

• In installations involving wrought iron or steel, a specialised putty should be used to seal them.

• Sealing material that complies with the BS6956 standards, part 5 or equivalent may be used.

7 Purge the air from the gas supply line before using it.

8 Open the unit's main gas supply valve.

9 Apply a soapy water solution to all joints to test for any leaks.

D AN G E R

• DANGER OF EXPLOSION. Never use a flame to verify the absence of leaks in the installation joints.

• During gas supply line pressure tests with pressures greater than 0,5 PSI (3,5 kPa), the burner and its manual shut-off valve must be disconnected from the system of gas supply pipes.

Gas. Modification for service with LPG (Liquefied Petroleum Gas, propane gas)

All units with gas heating are specially manufactured to operate with natural gas. The unit can be modified to operate with LPG (Liquefied Petroleum Gas, propane gas) if necessary. This involves a conversion kit that is assembled during the installation work.

A specific line should be used for gas supply. Its installation must comply with country and local safety regulations.

The LPG propane pressure must be at 37 mbar with the unit at full load for it to operate correctly.

Three main factors must be taken into consideration in order to keep the gas pressure values correct:

1 Speed of gas evaporation, which depends on:

a. the temperature of the liquid and

b. the size of the "wet surface" of the container or containers.

Check that the air dampers and their drive motors work correctly.

If the unit has an axial exhaust fan (accessory):

Check the condition of the fan and the operating control.

Condition of the unit structure and components

Check the correct condition of the unit structure and outdoor components for knocks, dents, scratched paint or rust. Check that screws are properly secured and the condition of leak-proof seals and panel locks and make sure they close properly.

Hot water coil (accessory)

Before the start of each season of operation, check the level of water in the system, that air has been purged from the coils, and the operation of control components.

Depending on the climate where the unit is installed, the mix of anti-freeze and water must be checked.

Gas valve filter

D AN G E R

Close the unit's gas supply valve before accessing the valve filter.

Gas filter -B- of the valve is found under a cover -A-, on the side of the valve.

Check the condition of the gas filter in both valves. Clean and replace it if necessary.

To install a filter, position it correctly -D- and put the cover in place pressing the four fastening screws C- uniformly in order to assure it is air tight.

Burners

Check how the flame in the burners looks.

If it does not look right, the burners may need cleaning. To do so, remove the burner group as specified in

Instructions for burner and injector inspection , see on page 38

Gas injectors

Visually check that the injector calibrated holes are not partially obstructed. Clean them if necessary as described in

Instructions for burner and injector inspection , see on page 38

Combustion air intake

Check that the combustion air intake is free of obstruction from dirt, snow, branches, dry leaves, residue or other objects.

Discharge of combustion gases

Check that the combustion gasses discharge is free of obstruction from dirt, snow, branches, dry leaves, residue or other objects.

Check that that there is no accumulation of soot on the panels around the exhaust tubes. If there is soot accumulated, it could be that combustion is incomplete. If that is the case, make the checks indicated in

Post start up checks , see on page 30

Instructions for burner and injector in‐ spection

D AN G E R

Close the gas supply valve and shut off the electrical power to the unit before inspecting the burners and injectors.

Cleaning the flue passages and heat ex‐ changer

As long as combustion regulation is adequate, it is rare that the heat exchanger needs to be cleaned. If the heat exchanger becomes sooty, it may be cleaned in the following manner:

1 Remove the burner group according to

Instruc‐ tions for burner and injector inspection , see on

page 38

2 Remove the screws from the upper part of the

casing and from the top turbine of the combustion gas draft blower.

3 Remove the screws that hold the upper part of the

flue box without tearing the insulation beside it. Afterwards, remove the central plate dividing the upper and lower flue boxes.

4 Take out the flue baffles from inside the flue box -

C- from inside the heat exchanger pipes -B-. No‐ tice that the last curve in the baffle fits tightly in the pipe -A-, requiring the end of the baffle to be well secured to the tube collar -D-. To take it out, move the end of the baffle towards the centre of the tube, freeing it from the tube collar and then pulling out in a straight line.

5 Using a metal brush with a flexible rod, brush the

interior of each of the tubes, brushing to the out‐ side and getting to the very end in the flue box as well as at the beginning at the burners.

6 Also brush all of the inside of the flue box and the

baffles.

7 Run the brush over the the exhaust hoods, from

the side of the flue box downward.

8 If there is a large accumulation of soot, take the

draft blower out and clean the turbine and casing.

9 Once the brushing is finished, carefully clean the

residue using compressed air. If necessary us a vacuum cleaner.

10 Put the parts back in the reverse order from which

they were removed.

11 When remounting the central and upper parts of

the flue box, be careful not to tear the insulation beside it.

12 Make sure that all of the joints on the side with the

combustion system ventilation are air tight. Apply high temperature (260 °C) sealing putty to do it.
