DANGER

SAFETY PRECAUTIONS

Before starting any installation, service or maintenance operation, turn the main power switch off in
order to avoid electrical shock that may cause personal damages.

 In case of folding electrical panels, before folding them up in order to access to the interior of the machine, it is

MANDATORY to disconnect the power supply hose from the electrical voltage, THE LINE MUST ALWAYS BE
FREE OF VOLTAGE for this operation.

 It is absolutely forbidden to carry out work on electrical live parts. The protection class of the opened unit is IP00!
 Check the safe isolation from the supply using a two-pole voltage detector.

 Do not touch or adjust the safety elements inside any unit. For repairs use only original spare parts and install them

properly in the same position of the replaced parts.

 The installation and maintenance of air conditioning equipment may be dangerous due to the pressure of the

system, the high temperature of some of its parts and the electrical components.

 Do not install the unit in an explosive atmosphere.
 If the motor of the fan runs independently after the unit has been switched off because it is pushed by airflow,

dangerous voltage of more than 50 V may be present in some of the internal connections of the motor. In that case
the fan is working as a generator.

 When there are EC motors or motors with variable speed control, the protective earthing is conducting high

discharge currents (depending on the switching frequency, the current source voltage and the motor capacity).
Earthing in compliance with EN specifications shall therefore be observed even for testing and trial operations (EN
50 178, Art. 5.2.11). Without earthing, dangerous voltages may be present in the motor housing.

 Due to the use of capacitors, danger of death exists even after switching the device off in case of direct contact with

conductive parts or with parts that carry voltage due to fault conditions. To remove or to open the housing of the
controller and the terminal box for example is only allowed after the power supply cable has been disconnected for 3
minutes.

WARNING

SAFETY PRECAUTIONS

 Only qualified and trained service staff (technical service) is authorized to carry out installation, commissioning and

maintenance. Unqualified personnel will carry out basic tasks only such as cleaning and replacement of filters, or
filter cleaning (excluding refrigerant filters), etc.

 Prevent access to children so that they cannot play with the appliances.
 For each visit, all precautions must be taken into account: those recommended in the installation, operation and

maintenance instructions, as well as the ones indicated in the stickers placed on the unit. Do not forget to strictly
follow any other legal safety precautions.

 DO NOT introduce objects into the air inlets or outlets that can be drawn into the fan, people, etc.
 The fan / motor may start and stop automatically due to functional reasons.
 After a power failure or a main disconnection an automatic restart of the fan takes place when power supply returns!
 Never approach the fan until it has stopped completely as it may be rotating even though it is not connected to the

power supply! Strong airflow could push it.

 When the motor is provided with an external rotor, the rotor rotates during operation.
 Use safety glasses, work gloves and any other safety accessory that may be necessary for the operation.
 For brazing operations use a quenching cloth and make sure you have fire extinguisher close to you.
 This product contains fluorinated greenhouse gases. In case of leakage air may be displaced which may cause lack

of oxygen when breathing.
The decomposition of fluorinated gases when being burned during brazing operations for example may cause the

presence of highly toxic and corrosive gases.

use will be born by the person or the operating company of the unit and not by the manufacturer.

 All the safety recommendations must be followed carefully.

levels that the security valves would be activated.

1. Moreover, when temperatures decrease water condensation may occur inside the machine or between the machine
and the plastic wrap.

 Avoid placing objects on top of the unit (unless this is permitted according to the drawings or the overlap diagrams

indicated on the packaging, etc. Follow these indications).

 In case of prolonged storage before installation avoid the penetration of water, dust and objects in general caused by

invasion or biological, meteorological and/or human impacts.

 Minimum storage temperature: -10ºC.

2. If some components contain water, it is compulsory to empty them or to add an antifreeze solution to make sure that
the freezing point will always be lower than the ambient temperature.

 Maximum relative humidity: 90%.

INSTALLATION SITE

 Read and comply with the local rules and regulations applying to the installation of air conditioning systems.
 Choose a clean place without dust nor debris.
 Respect the allocated service area prepared for the equipment.
 Verify that the ground or the structure prepared for the equipment is strong enough to support its weight during

operation.

 Install shock absorbers throughout the installation to prevent the transmission of noise and vibration.
 Check that the direction of the sound level will not annoy anybody.
 The standard version of this equipment has been designed for installation inside a building (with a roof). It is not

prepared for installation outside. Please check with Hitecsa if you plan to expose the machine to weather conditions.

SERVICE AREA (mm)

UNIT SETTLEMENT

 Make sure that the unit is slightly inclined (~2%) following the direction of the drains.
 The bed frame shall be big enough and strong enough to support the unit weight.

DRAINAGE

 All the drain devices are prepared with a male 3/4” gas connection (ISO 228-1, BSPP).
 The unit is equipped as a standard feature with a condensate drain tray to avoid an excessive water accumulation in

the indoor side and the outdoor side.

 The condensate drain pipe diameter shall be equal or larger than the unit connection depending on its length and

inclination.

 If the drain line is exposed to air temperatures lower than 0 degree, it is necessary to cover it with thermal insulation

material or to use electrical heating devices to prevent water from freezing that would entail tube damage.
The drainage line shall be inclined by 2% minimum for proper water evacuation.

 It is convenient to install a drain trap with proper dimensions (see diagram) or a

draining system with a condensate pump to avoid excessive water accumulation
in the indoor side and the outdoor side.

OPERATION

START-UP

 Make sure you have access to measuring instruments with their up-to-date calibration certificates.
 Thermometer, anemometer, voltmeter, hook-on meter, high and low manometer.
 The person/people who will complete the measuring operations or the ones who will participate in the start-up

process must be qualified professionals with the valid certification according to the local regulation.

 Please read all the security precaution guidelines.
 Before using a hook-on meter make sure that the cable or the cables are connected properly. To disconnect a cable

by using force may damage the equipment and entail people injuries.

 It is necessary to register the air inlet and outlet temperatures to the internal coil, the volts and amps of the

compressor and motor fan, as well as the suction and discharge pressure of each compressor.

 Remember that it is necessary to clean the air filters after the first 4 hours of operation.
 Complete at least 3 cooling cycle operations.

 Indoor fan start-up:

- Do not approach the fan while it is rotating even at a very slow rotation speed!

- Beware automatic restart!

The fan / motor may start and stop automatically for functional reasons.
After a power cut or a technical failure the fan will restart as soon as voltage is present again!

- ROTATION CAUSED BY AIR FLOW IN THE WRONG DIRECTION.
If you switch the fan on while it is rotating in the opposite direction the control will reduce the rotations until it

reaches the ‘0’ value (fan stoppage). Then, the control will make a restart in the correct rotation direction.
The higher the number of rotations in the wrong direction, the longer time the control will need to make the fan

stop. If the fan is rotating heavily in the wrong direction the control may not be able to start the fan in the correct
direction.

Do not switch the fan off and restart it again to slow it down!

Before completing any service or maintenance operation, turn the main power switch off to avoid any
personal injuries. Lock it so that anybody else than a qualified technician can switch it on.

Never use oxygen to pressurize the system or purge lines for leak test. Oxygen reacts violently with oil

which may entail an explosion that could lead to damages, personal injury or event death.

Should it be necessary to complete brazing operation first of all proceed to filling the circuit with dry

nitrogen. Burning refrigerant produces toxic gas emissions.

WARNING!

WARNING!

WARNING!

MAINTENANCE

 It is advisable to schedule maintenance visits every 1,000 operating hours, as well as at the end of summer. Please

keep an updated record of all maintenance operations and readings (maintenance sheet).

 Repairing operations must be carried out by trained specialists only.
 Wear safety shoes and gloves adapted to each operation!
 Please observe the safety regulations and the worker’s protection rules for any maintenance and service operation

(EN 50 110, IEC 364).

 In the event of leak any manipulation and/or recovery of refrigerant shall be completed by qualified and authorized

personnel in accordance with the valid regulation. Add the quantity of oil that has been lost.

REFRIGERANT CHARGE

 Should it be necessary to add or recover refrigerant use a digital scale that is suitably reinforced and prepared to

withstand the handling of the refrigerant bottle.

 Charge to be in the LIQUID state.
 Introduction of R-410A refrigerant in the liquid state inside empty tubes produces temperatures below 0ºC until the

internal pressure reaches 7 bars.

 Leaks should be repaired immediately.
 Never overcharge the system.
 Never use the compressor as a vacuum pump.
 If leakage symptoms appear during operation proceed to a leak test.
 A HCF detector is necessary in case of small leaks.
 If a gas leak is detected proceed to removing and recuperating the entire refrigerant charge. Pressurize the system

with dry nitrogen. If no leak is detected proceed to vacuuming the system and refill with refrigerant.

Do not reintroduce the used refrigerant, send it to an authorized recycling plant.

COMPRESSOR LUBRICATION

R-410A refrigerant compressors use synthetic oils. Each manufacturer uses a specific oil for his product.
The compressor or system should not remain open to atmosphere for more than 15 minutes.
The used synthetic oils are of type POE (Polyol Ester) and PVE (Polyvinyl-ether). They have a high solubility level with
the R-410A. These types of oil are very hygroscopic and shall be handled with more care than the conventional oil.
Moreover, when these synthetic oils are mixed with minerals (MO) or alkylbenzenes (AB), they deteriorate causing
capillary blockage or failure in the compressor.

DO NOT MIX THEM UNDER ANY CIRCUMSTANCES.

MAINTENANCE

CONSERVATION AND CLEANING

Precaution!

 Do not use aggressive cleaning products nor varnish solvents.
 Avoid water penetration inside the motor or the electronic components (e.g. through the direct contact with joints or

holes of the motor), observe the protection class (IP).

Electrical circuit: Make sure that all the electrical connections –wires, contactors and terminals- are properly tight.

Register the readings of kW and amperes at each compressor and fan motor phase. Check the start current. Check that
all the mechanical components, pressure switches and so on are working properly.

Refrigeration circuit: Check if there is any refrigerant leak, noises or vibration. Proceed to measuring temperatures

and/or pressures of the most important components of the system and register them on the maintenance sheet
(compressor discharge and suction, expansion valve, exchangers’inlet and outlet, etc…).

Compressor: Check regularly the lubricant level, the presence of vibrations or noise and the motor insulation.
Drainage system: Verify the condition and the correct operation of the drainage tray and drain trap. It is necessary to

clean the condensate trays after the first day of operation. Then, clean them at least once a year. Take into account the
meteorological conditions, e.g. in areas where falling leaves or the flight of seeds may obstruct the drain trap. Clean
them also at mid and late spring and autumn. The dates are approximate and will depend on the plants blooming, falling
leaves and seeds seasons. Other factors such as human activities may interfere in the cleanliness conditions.

Air filters: Clean the filters after the first operating hours to remove possible light materials such as pieces of paper or

polystyrene, etc. that may have been dragged through air circulation. Clean again every 3 months (or more often
depending on operation). The filters can be cleaned with soapy water. Then rinse them with clean water and let dry. If
necessary replace the filters before they are in poor conditions (refer to the current legislation, EN 779, UNE-EN
13053…).

Coils: At least once a year clean the coils with water and detergent, then dry with air at low pressure. Never clean with a

wire brush, water and/or air at high pressure (max. 6 bar).

Fans: Check the direction of rotation of the fans, verify the supporting parts. Check the transmission elements and the
operating status.

Before handling the fan make sure that it is disconnected from the main power supply even though it is already stopped
and control that nobody may start it during the intervention.

- A regular inspection of the unit is required to avoid dirt accumulation in propellers, turbines, motors and grids that
could entail risks and significantly shorten their life. The frequency will depend on the working conditions.

- Keep the airways of the fan free – danger because of objects dropping out!

- Check the free flow of the condensation water through the evacuation openings is necessary (if there are any).

- During cleaning operations be very careful not to unbalance the propeller or the turbine.

- In case of incorrect cleaning operations no guarantee is assumed regarding corrosion formation / paint adhesion for

unpainted / painted fans.

- To avoid humidity accumulation in the motor the fan must be operated during at least 1 hour at 80 to 100% of its
maximum speed before cleaning!

- After cleaning, the fan must be operated during 2 hours at 80 to 100% of the maximum speed to dry it!

- Check the fan regularly to detect possible mechanical vibrations (recommended every 6 months). Keep in mind the

limit values indicated the ISO 14694 and perform correction measures in case of exceeding them (e.g. posterior
balance to be completed by trained specialists).

- Check the impeller, in particular weld-seams, for possible cracks.

- The fan or motor is maintenance-free due to the use of ball bearings with “life-long lubrication”. At the end of the

grease life (30-40.000h approx.) it is necessary to replace the bearing. Please contact our Service Department in this
case as for all other damage (e.g. to the coil or electronics).

REFRIGERANT DATA

SAFETY DATA: R410A

Toxicity

Low

Contact with Skin

R410 A vapours can irritate the skin and eyes. In liquid form, it can freeze skin on contact. If contact with skin occurs,
flush the exposed area with lukewarm water until all of the chemical is removed. If there is evidence of frostbite, bathe
in lukewarm water.

Contact with Eyes

If contact with eyes occurs, immediately flush with large amounts of lukewarm water for at least 15 minutes, lifting
eyelids occasionally to facilitate irrigation. Seek medical attention as soon as possible.

Ingestion

Very unlikely - should something happen, it will cause frost burns. Do not induce vomiting. Only if the patient is
conscious, wash out mouth with water and give some 250 ml of water to drink. Then, obtain medical attention.

Inhalation

Inhalation of the R410A vapour may cause irritation. Vapour inhalation at high concentrations may result in asphyxiation
or the heart may become sensitized, causing cardiac arrhythmia. When concentration of R410A reach levels which
reduce oxygen to 14-16% by displacement, symptoms of asphyxiation will occur. An individual exposed to high
concentrations of R410A must be given medical attention immediately. Adequate ventilation must be provided at all
times.

Recommendations

Semiotics or support therapy is recommended. Cardiac sensitisation has been observed that, in the presence of
circulating catecholamines such as adrenalin, may cause cardiac arrhythmia and accordingly, in case of exposure to
high concentrations, cardiac arrest.

Prolonged Exposure

R410A: a study on the effects of exposure to 50,000 ppm during the whole life of rats has identified the development
of benign testicle tumour.
This situation should therefore be negligible for personnel exposed to concentrations equal to or lower than professional
levels.

Professional Levels

R410A: Recommended threshold: 1000 ppm v/v - 8 hours TWA.

Stability

R410A: without specifying

Conditions to Avoid

Do not use in the presence of high temperatures, flames, burning surfaces and excess humidity.

Hazardous Reactions

Contact with certain red-hot metals may result in exothermic or explosive reactions and yield toxic and/or corrosive
decomposition products. Specific materials to avoid include freshly abraded aluminium surfaces and active metals such
as sodium, potassium, calcium, powdered aluminium, magnesium and zinc.

Hazardous Decomposition

Products

R410A: Halogen acids produced by thermal decomposition and hydrolysis.

General Precautions

Do not inhale concentrated vapours. Their concentration in the atmosphere should not exceed the minimum preset
values and should be maintained below the professional threshold. Being weightier than the air, the vapour
concentrates on the bottom, in narrow areas. Therefore, the exhaust system must work at low level.

Respiratory System

Protection

If you are in doubt about the concentration in the atmosphere, it is recommended to wear a respirator approved by an
accident prevention Authority, of the independent or oxygen type.

Storage

Cylinders must be stored in a cool, dry and properly ventilated storage area away from heat, flames, corrosive
chemicals, flumes, explosives and be otherwise protected from damage. Keep a temperature below 50°C.

Protective Clothing

Wear overalls, protective gloves and goggles or a mask.

Accidental Release

Measures

It is important to wear protective clothing and a respirator. Stop the source of the leak, if you can do this without danger.
Negligible leaks can be left evaporating under the sun, providing that the room is well ventilated. Considerable leaks:
ventilate the room. Reduce the leak with sand, earth or other absorbing substances. Make sure that the liquid does is
not channelled into gutters, sewers or pits where the vapours are likely to create a stuffy atmosphere.

Disposal

The best method is recovery and recycling. If this method is not practicable, dispose according to an approved
procedure, which shall ensure the absorption and neutralization of acids and toxic agents.

Fire Fighting Information

R410A: Not flammable in the atmosphere.

Cylinders

The cylinders, if exposed to fire, shall be cooled by water jets; otherwise, if heated, they may explode.

Protective Fire Fighting

Equipment

In case of fire, wear an independent respirator and protective clothing.
