The warranty of the unit will not respond to the damages caused by frozen water.
WARNING!
SAFETY PRECAUTIONS
Before starting any installation, service or maintenance operation, turn off the main power switch 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, IT MUST ALWAYS BE FREE OF VOLTAGE for this operation
DANGER
Do not touch or adjust the safety elements inside of any unit of the system. In repairs use only original spare parts
and install them properly in the same position where old parts were placed.
The installation and maintenance of air conditioning equipment could be dangerous because the system is under
pressure, some of its elements have high temperatures and include electrical components.
Do not install the unit into an explosive atmosphere.  If it was necessary to open the electrical panel and access the inside of the machine it is MANDATORY to
disconnect the power supply hose from the machine. It MUST BE FREE OF VOLTAGE for this operation.
It is generally forbidden to carry out work on electrical live parts. Protection class of the device when it is complete
opened is IP00! Be careful, do not touch hazardous voltages directly.
Check the safe isolation from the supply using a two-pole voltage detector.  Even after disconnecting the main voltage, life-threatening charges can appear between the protective ground
“PE” and the main connection.
Units with water-air, water-water or refrigerant-water heat exchangers must be conveniently protected from breaks
by freezing when the room temperature can reach values lower than 5 ºC. In this case, it is mandatory heat, remove completely the water or add antifreeze to ensure that the freezing point
is always lower than the room temperature.
When the motor runs independently due to air flowing through or if it continues to run down after being
turned off, dangerous voltages of over 50 V can arise on the internal connections of the motor through operation of the generator.
When there are EC motors or motors with variable speed control, the protective earth is conducting high discharge
currents (depending on the switching frequency, current source voltage and motor capacity). Earthing in compliance with EN specifications shall therefore be observe even for testing and trial conditions (EN 50 178, Art.
5.2.11). Without earthing, dangerous voltages can be present on the motor housing.
Through use of capacitors, danger of death exists even after switching off the device in case of direct contact with
conductive parts or with parts that carry voltage due to fault condition. It is only allowed remove or open the housing of the controller when the power supply cable is disconnected and after a waiting time of 3 minutes.

WARNING!
SAFETY PRECAUTIONS
Only qualified and trained service staff (technical service) must make the installation, commissioning and carry
out maintenance works. Unqualified personnel can only make basic tasks such as cleaning and replacement of filters, etc.
Prevent access to children so they cannot play with the appliances.  In every visit, all precautions must be taken into account: those recommended in the installation, operation and
maintenance instructions, as well as the ones indicated in labels of the unit. Do not forget to strictly follow any other safety precautions.
DO NOT introduce objects into the air inlets or outlets that can be drawn into the fan, people, etc.  Use safety glasses, work gloves and any other safety accessory necessary.  The fan / motor may switch on and off automatically for functional reasons.  After power failure or main disconnection an automatic restart of the fan takes place after voltage return!  Wait for the fan to come to a complete standstill before approaching it!  In the AC external rotor motor the external rotor turns during operation!  For brazing operations use a quenching cloth and take precautions to have at close distance a fire extinguisher.
This product contains fluorinated greenhouse gases, its leakage can cause displacement of air and cause
insufficient oxygen to breath. The decomposition of fluorinated gases when being burned due to e.g. brazing operations, may cause the
existence of highly toxic and corrosive gases.
Must follow all safety recommendations.

Recommended drain trap measures
INSTALLATION
WATER DRAIN
The indoor drain unit (of condensate water) has a 3/4” gas (ISO 228-1, BSPP) male connection.  Condensate drain pipe diameter should be equal or larger than the unit connection depending on the line length
and general building configuration.
The drainage line should be inclined a minimum 2% for proper water evacuation.  When drain line is exposed to air temperatures below 0 degrees, it is necessary to cover with thermal insulation
or electrical heating wire to avoid water freezing and tube damage.
It is convenient to install the drain trap with proper dimensions (see diagram).
AIR DUCTS
Air duct dimensions will be determined according to the airflow and available pressure of the unit.  Ducts must be designed by qualified technical people.  Use ducts made of non-inflammable materials in order to avoid any risk of fire as a consequence of the
deflagration of gases. It is advisable to use metal sheet duct with insulation.
Use flexible ducts to connect air ducts into the unit and thus avoid vibration and noise transmission.  A bad design of the ducts will reduce the performance of the machine and may block access to maintenance or
change filters, fans, etc., especially when there is only one access.

INSTALLATION
INSTALLATION OF WATER PIPES
Preliminary information
The selection and installation of the components of the installation have to be done by a qualified installer, respecting the current legislation of the place of the work and standards of good practice.
The design and calculations of the pipes will be made in a way that the pressure drop of the installation never surpass the one that could beat the incorporated pump of the unit. Moreover, a bad design of the pressure drops of the pipes that connect with the indoor units may cause the wrong operation of some of them.
Components
- Shut-off valves: Installed at the entry and exit of every component, they allow to do the maintenance operations without emptying the installation.
- Thermometers and manometers: Installed at the entrance and the exit of the principal elements. Ease the maintenance and control operations.
- Steam traps: Installed at the highest points of the installation. Allow the air purge of the circuit.
- Drain keys: Install them in all low points of the circuit to allow their emptying.
- Supports: The weight of the pipes must not be supported by the connections of the unit. Therefore, flexible elements will be installed to prevent it.
- Expansion tank: Keeps the correct pressure of the installation. It is recommended to fill it at 2.15 bars, when the water temperature changes from cold to pump and vice-versa. The expansion tank has to be sized depending on the content of water of the installation.
In special circumstances may be necessary to install one or more additional tanks even when the unit has already one.
Safety elements
The installation of the following safety elements is MANDATORY when they ARE NOT incorporated as standard at the unit. Its non-compliance will cause the LOSS OF WARRANTY.
Water filter
The water filter will be installed and must contain a mesh inside to retain particles with a diameter not greater than
Ø> 0.5mm
At the water inlet of the unit, to protect the heat exchanger or other critical components from obstructions.
Flow switch or differential pressure switch
Water heat exchanger protection from breaks due to an insufficient water flow and can cause the total disqualification
of the unit.
It is mandatory to install the flow switch at the water outlet of the unit, with a horizontal stretch of 6Ø inlet and 5Ø
posterior of horizontal length, without section changes at the stretch to ensure the laminar regime of the water/fluid flow. In case of placing flow switches that are not supplied by HITECSA, follow the manufacturer instructions, provided that the aforementioned lengths do not decrease.
Risk of frost
If the unit or the corresponding hydraulic connection depend on the temperatures close to 4 ºC, take the convenient measures to prevent the risk of frosts.
For example:
Mix the installation water with glycol.  Protect the pipes with warming cables placed below the insulation
Empty the installation checking that:
There is no closed keys that may retain water even after the emptying.  There is no low points which water can hold back even after the emptying, make a blowing if necessary.
Glycol additions
Take into account the use of glycol solutions increases the pressure drop. Make sure the type of glycol used is compatible with the components of the hydraulic circuit (pumps, filter keys, etc.).

INSTALLATION
WPHA / WPHBA HYDRAULIC CIRCUIT AND ITS COMPONENTS
Within the hydraulic circuit and its components, the plate heat exchanger is the most delicate affected part, and as a result must follow at least these guidelines:
- The installation must be made according to the diagram of hydraulic connections (see below).
- The maintenance of both the filter and the flow switch must be done within periods in which the locking dressings
are avoided.
- The inlet and outlet water of the unit must be respected and install, if necessary, a bypass valve. The units that incorporate a plate heat exchanger must work in both an open hydraulic circuit and a thermal ring within the control values in the attached table.
Surpassing the Langelier index below or above can generate corrosive or fouling water, so the component would be at risk and the equipment warranty would be denied. In this case, you should work with a secondary exchanger, adapted to the quality of the water.
WATER CONNECTIONS WITH OPTIONAL PRESOSTATIC VALVE
Install the Bypass solenoid valve with presostatic valve option in the heat pump units.
NOTE: The pressure tap of the presostatic valve must be connected to the high pressure outlet of the unit. Graphs show connections for heat pump units. In case of cooling only units, do not mount the solenoid valve. While mounting the presostatic valve, the performance of the flow switch on the compressor start­up must be timed during 1 minute, to let de valve act.

It is mandatory to install the flow switch in the water inlet of the machine with a previous section which
length is 6 times the Ø of the inlet and 2 times the Ø of the outlet of horizontal lenght without any section
change in order to ensure that the flow rate of water/fluid is laminar. In case of installing flow switches that
are not supplied by HITECSA, follow the instructions of the manufacturer, provided that the
abovementioned lengths do not decrease. Failure to comply these guidelines causes loss of the equipment
warranty.

OPERATION
BEFORE START UP
Start up has to be performed by a qualified service personnel in air conditioning.  Make sure that panels are firmly secured with screws.  Check that there is no leakage of oil or refrigerant.  Ensure that the unit is evenly levelled.  Check if there is enough space for operation and maintenance.
Before opening the electrical panel and having access to the inside of the machine it is MANDATORY to disconnect the power supply hose of the machine which MUST BE FREE OF VOLTAGE for this operation.
Check that the drainage is not blocked.  Verify if there are losses of water. Check that the valves work correctly.  Check the water circuit allows its emptying for repairs or stop and its correct air purge.  Always use the electrical diagram of the unit to make the connections.  Make sure that all electrical connections are properly tight.  The power supply of the unit must be as indicated on the serial plate. Damage caused by the start-up of the unit
in an incorrect voltage line is not covered by Hitecsa’s warranty.
The unit must not be supplied with any other voltage than that indicated on the serial plate. The power supply to
the unit must be within 10% of the voltage indicated on the serial plate.
Check the correct rotation direction of the fans.  The installer must place line protection elements in accordance with current legislation.  Wiring of electrical connections must be protected by a tube or other cable conduits.  Make sure if the crankcase heater of each compressor has been operating during 24 hours prior the Start Up.  Check that the air filters are clean and correctly fitted.  Check the condition and placement of grilles, diffusers, air ducts, tarpaulins, etc.
START UP
It is very important to evacuate air from the system and clean dirt particles of the water circuit. The two operations must be done at the same time.
At first start up the water pump for a few minutes.  Stop the water pump and notice if the automatic purge is working. Repeat this operation 10 times. If it proceeds
in this way, all the existing air will go out from the system and the water circuit will be filled.
The next step is to remove the water mesh filter and clean it. The performance of the system will improve since
the dirty mesh filter has a high pressure drop.
It is necessary to take notes of 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.
It should be remembered that it is necessary to clean the air filters after the first 4 hours of operation.  Observe, at least, 3 cooling cycle operations.

Before performing any service or maintenance operation it is mandatory to turn off the main power switch of
the system to avoid any personal injuries. Locked it so that nobody other than a qualified technician can
switch on electrical power.
Read the SAFETY PRECAUTIONS!
WARNING!
MAINTENANCE
It is advisable to do maintenance works every 1.000 operating hours as well as at the beginning of each cooling season.
Refrigeration circuit: Check for oil or refrigerant leaks, noises or system’s vibration. Take measurements of
temperatures and pressures of components and record them on the maintenance form.
Electrical circuit: Make sure that all electrical connections –wires, contactors and terminals- are properly tight.
Record the readings for volts and amperes of each compressor and fan motor. Verify the starting current. Check the good operation of all relays, pressure switches and phase sequence relay of Scroll compressor.
Fans: Check the direction of rotation of the fans and examine the support of them. Verify the operating status.
- Before handling the fan, make sure that it is completely stopped and disconnected from the mains, even if it is already stopped and no one can start it during the intervention.
- Regular inspection of the device is necessary. The frequency of it, must be taken based on the degree of dirt in propellers, turbines or impellers. The dirt in impellers (propellers or turbines), motors and grids can involve risks and shortens significantly the life of the fan.
- Keep the fan's air circulation paths clear of obstacles - danger due to shot out objects!
- It is necessary to check the free passage of condensation water evacuation holes (if they exist) suitable for the assembly position.
- In cleaning operations be very careful not to unbalance the propeller or turbine.
- If the cleaning work is carried out improperly, in the case of non-painted / painted fans, no guarantee is assumed as regards the formation of corrosion or adhesion of the paint.
- To prevent humidity accumulation in the motor, before the cleaning process, the fan must operate for at least 1 hour between 80 and 100% of the maximum number of revolutions!
- After the cleaning process, the fan must work for 2 hours between 80 and 100% of the maximum number of revolutions to dry!
- Check the fan for mechanical vibrations at regular intervals (recommended every 6 months). Be aware of the limit values indicated in ISO 14694 and carry out relief measures in case of exceeding these (e.g., the subsequent balancing by expert personnel).
- Check if there are cracks in the impeller (propeller or turbine), especially in the welding seams.
- Motors and fans do not need any additional lubrication "thanks" to the use of lubrication for life. After the useful life of the grease expires (30-40,000 h approx.) a change of bearings is required. In view of that, as for any fault (e.g. in the winding or in electronic systems), please contact our technical assistance department.
Air filters: Clean air filters after 4 hours of system operation and every 3 months (or more depending on application).
Filters can be cleaned by immersion in warm water with soap, later washed in clean water and dry.
Coils: At least once a year, clean condenser 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.
Drainage system: Verify condition and good operation of the drainage tray and drain trap. It is necessary to clean
the condensates trays after the first day of operation. Then, clean it at least once a year. Take into account the meteorological conditions, e.g. in places where falling leaves or the flight of seeds can plug the drain trap, it will also be necessary to clean them at mid and late spring and autumn. The dates are approximate and will depend on the blooming, falling leaves, seeds, etc. of the plants of the zone or the human activity or any other cause.
Hydraulic Circuit: Check for water leaks, as well as noise and vibrations of the system elements. Record water
pressure values at the inlet and outlet of the pump.
- Clean the filter and the flow switch, it should be done frequently enough to avoid deposits that could block them.
- Make sure you know and comply with all local laws and regulations that affect the maintenance of water facilities.

MAINTENANCE
Plate heat exchanger: it is necessary to clean the plate heat exchanger of the evaporator at least once a year.
The plate exchanger is cleaned by circulating the cleaning liquid inside. A deposit with acid (5% phosphorus acid should be used, and if it is necessary to clean more frequently, use 5% oxalic acid). Introduce the cleaning liquid through the heat exchanger. To achieve an effective cleaning, the acid should be circulated at least 1.5 times the normal flow rate of water, and if possible in the opposite direction. Then the circuit must be cleaned with a large amount of water to remove traces of acid. Put new water and start.

Compressor: Check regularly the lubricant oil level, the presence of vibrations or noises and the insulation of the
motor.
DO NOT FORGET to stop the crankcase resistance for 24 hours before starting up the compressor. COMPRESSOR LUBRICATION
- Compressors with R-410A refrigerant use synthetic polyester lubricant oils. Each compressor manufacturer has a specific lubricant oil for its product.
- The compressor or system must not be open to the air for more than 15 minutes.
- The synthetic polyol-ester lubricant oil has the capacity to absorb humidity 100 times more than the mineral oil used with the R22 refrigerant.

WARNING!
WARNING!
Do not disconnect the mains voltage so that the fan can start again!
The safe starting of fans is not guaranteed if they are driven in the opposite direction. If the application requires a safe start, the manufacturer of the installation or the user has to take
the appropriate measures to prevent a reverse drive.
MAINTENANCE
REFRIGERANT CHARGE
Never use oxygen to pressurize system or purge lines for leak test. Oxygen reacts violently with
oil, which can cause an explosion resulting in damage, personal injury or death.
In case it is necessary to add or recover refrigerant, use an electronic scale that is suitably reinforced and prepared to
withstand the handling of the refrigerant bottle.
The charge must be made in LIQUID condition.  The inlet of liquid refrigerant R-410A in the empty tubes causes temperatures below 0ºC until the internal pressure
reaches 7 bars.
If it is necessary to make brazing operation, first fill the circuit with dry nitrogen. Burning
refrigerant 410A results in toxic gas emissions.
Leaks should be repaired immediately.  Never overcharge the system.  Never use compressor as vacuum pump.  If leakage symptoms appear during the operation, it is necessary to leak test.  To find small leaks, you will need a detector for HCF.  If gas leak is detected is necessary to remove and recuperate complete refrigerant charge. Pressurize system with
dry nitrogen. If leakage has been not detected break a vacuum, dehydrate and charge with refrigerant.
Do not reintroduce used refrigerant, send it to an authorized recycling location.
FAN WITH EC MOTOR
Rotation caused by an Air Flow in the opposite direction
When the fan is stopped (no signal, no power supply, etc. ...), the motor control does not intervene if the fan rotates in the
opposite direction (due, for example, to an air flow). If we put the fan in operation while turning in the opposite direction, first the control will reduce the rotations in a controlled manner until it reaches the value "0" (stop of the fan). Then the control will make a new start in the proper direction of rotation.
The higher the number of turns in the opposite direction, the longer the control will be needed to stop the fan. In the event that the fan rotates strongly in the opposite direction, the control may not be able to start the fan in the proper direction of rotation.

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.
Medical Advice
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 pre-set 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.
