TRANSPORT & RECEPTION
INSPECTION AT RECEPTION
It is advisable to examine the equipment carefully at the time of its reception.
Check that the equipment has not been damaged during transport and it has been supplied complete with all
parts specified in the order and/or with the options specified in the order. If this is not the case, contact the
transport company immediately. (First 48h).
Verify the correct voltage of the nameplate and make sure it is in accordance with local power supply.
In case of any flaw or anomaly detected, please contact HITECSA.
RIGGING
Before moving the unit, make sure that all panels are well fixed.
Raise and set down the equipment carefully.
Do not tilt the unit more than 15 degrees during transportation. (Fig. 2).
Always transport the unit in its original packaging to the place of installation.
All units come with a particular rigging diagram of that model, similar to the one shown below. Be sure to hoist
the machine through the points indicated in the diagram.
Make sure that the unit is balanced, stable and without any deformations when it is lifted.
STORAGE
If the equipment is going to be stored before the installation, please follow the instructions below in order to avoid damages,
corrosion or deterioration:
Move it carefully.
Do not place the machine in places exposed to ambient temperature above 50ºC and preferably keep the unit away
from direct sunlight.
Avoid placing the unit with plastic wrapping protection under the sun, as the pressure of the circuits could assume
values that could lead to the intervention of the safety valves.
In addition, when cooling, water condensation occurs inside the machine and the plastic wrap.
Avoid placing other objects on top of the unit (unless it is done within the limits of the overlap planes indicated on the
packaging, etc. Follow these indications).
Avoid prolonged storage, before installation, water inlet, dust and objects in general due to invasion or biological,
meteorological and/or human inclemencies.
Minimum storage temperature is: 5ºC.
Maximum relative humidity: 90%.

Recommended drain trap
measures
INSTALLATION
DRAINAGE
The indoor drain unit (of condensate water) has a 3/4” MPT connection.
Condensate drain pipe diameter should be equal or larger than the unit drain connection depending on the line length
and general building configuration.
The drainage line should be inclined by minimum 2% for a proper evacuation of the condensation water and to avoid
deposits when possible.
When the drain line is exposed to temperatures below 0 degrees, it is necessary to cover with thermal insulation or
electrical heating wire to avoid water freezing and tube damages.
It is convenient to install the drain trap with proper dimensions (see diagram).
AIR DUCTWORK
Air duct dimensions will be determined according to the airflow and available static pressure of the unit.
Ducts must be designed by qualified technical personnel.
Use ducts made of non-inflammable materials in order to avoid any risk of fire as a consequence of deflagration
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.

INSTALLATION
HYDRAULIC INSTALLATION
The selection of the components and the installation shall be made by a qualified installer according to the valid local
legislation and the good practice rules.
Make sure that you are aware of all the local rules and regulations for hydraulic installations and that you comply with
them.
The design and calculation of the pipes shall be realised keeping in mind that the pressure drop of the installation shall
never exceed the pressure drop that would overcome the pump of the installation. A wrong design with inadequate
pressure drops in the section pipes that lead to the indoor units would entail the malfunction of some of them.
The installation shall be completed according to the hydraulic connection diagram (please refer to the below shown
diagram).
Proceed to the installation of a water filter that is provided with an inner net to retain the particles with a maximum
diameter of 0.5mm.
A proper maintenance of the filter and the flow switch at an appropriate periodicity shall be completed to avoid deposits
that could block them.
Comply with the stated indications regarding the water inlet and outlet of the unit and install a by-pass valve if necessary.
WATER FILLING
Use water at around 20ºC to fill the hydraulic circuit. After the system has been drained, the pressure level must be as
stated in the installation project or according to the pressure level of the main installation. In case when the water installation
of the unit is going to be added to an existing water installation, the main installation probably will comprise a filling system
already.
Attention: An expansion tank with a bigger capacity will be required according to the filled water volume.
Drainage
Verify that all the high points of the installation are provided with a bleed valve.
Use the pump during one minute, stop it and drain the circuit (if manual). Wait for another minute and repeat the same
process until there is no more water. 5 to 10 processes like this one may be necessary to drain the system completely for
water.
Remember to drain any other components that include tubes where there might be air pockets (example: differential
switch). They will not work properly with air.
Air in the circuit will produce noises, will entail a lower water flow and a bad performance of the exchanger, etc…
Risk of frost
If the unit or the water installation are exposed to temperatures around 4°C it is necessary to take the appropriate measures
against the risk of frost.
For example:
Mix the water of the installation with glycol.
Protect the pipes with heating cables placed under the insulation lining.
Empty the installation and control at the same time that:
There are no closed valves that may retain water even after draining the installation.
There are no low spots where water may stagnate even after draining; if necessary proceed to purging the installation.
Glycol additions
Keep in mind that the use of glycol solutions increases the pressure drop.
Make sure that the type of glycol you will use is compatible with hydraulic circuit components (pumps, filters, etc.) and that
it is a non-corrosive product.
Make sure that the freezing temperature is below the minimum temperature that the water may reach with a security margin
even when the unit is OFF.

INSTALLATION
THE HYDRAULIC CIRCUIT AND ITS COMPONENTS
The plate heat exchanger is the most fragile part of the hydraulic circuit. Therefore it is very important that the units provided
with a plate exchanger work in an open hydraulic circuit and in a closed thermal circuit within the control values as stated
in the following chart. The Langelier index shall not be exceeded (downwards or upwards) as in such a situation corrosive
or encrusting water may be produced. That would geopardize the component and the unit warranty would not apply. In
such a case a special exchanger suitable for this quality of water would be necessary.
Shut-off valves
Installed at the inlet and the outlet of each component, they allow to carry out the maintenance operations without having
to empty the installation.
Thermometers and pressure gauges
Installed at the inlet and the outlet of the main elements. They make maintenance and control operations easier.
Air release valves
Installed at the highest points of the installation. They enable air drainage of the circuit.
Drainage valves
Install them at all the low points to empty the circuit.
Supports
The weight of the pipes must not be supported by the connections of the unit. Therefore supporting rings shall be used.
Expansion vessel
It maintains the correct pressure of the installation, we recommend filling at 2.15 bar, when the water temperature varies
from cold to pump and vice versa. The expansion vessel has to be dimensioned according to the water content of the
installation.
In special circumstances it may be necessary to install one or more additional vessels even tif the unit already is equipped
with one.
Security devices
The installation of the following safety devices is MANDATORY when these elements ARE NOT included as standard
features. Not complying with this condition will entail the LOSS OF WARRANTY.
Water filter
At the water inlet of the unit, to protect the heat exchanger or other critical components from obstructions and/or clogging.
Flow switch
It aims at protecting the plate heat exchanger from breakage caused by a too low water flow that would make the equipment
completely inoperative.

INSTALLATION
Differential switch
We will use it instead of the flow switch or together with it. Its function is the same as the flow switch’s one. Air pockets
may be generated after filling the circuit with water. We will have to make sure that there is no air to garanty that this
component will work properly: we will proceed to purging by loosening the nuts of the tubes (please see below, 1.).
The warranty will not cover any damages to the plate exchanger caused by air in the switch that would be responsible
for its malfunction.
INSTALLATION OF THE FLOW SWITCH AS AN OPTION
It is compulsory to mount the flow switch at the water outlet of the unit. The water flow shall be laminar to make sure
that the flow switch works properly: Install the flow switch on a straight section of the tube where there is no section change.
The distance to the switch shall be minimum 6 times the diameter (D) of the tube and at the outlet there shall be a distance
of minimum 3 times the diameter of the tube. No other component or accessory shall be installed on that tube. If you use
a flow switch from another supplier (not delivered by Hitecsa), refer to the instructions of the producer and respect the
dimensions as previously stated.
Bear in mind that the flow switch has a limited operation range due to the tube diameter. We will need to choose the
diameter of the tube where it will be installed depending on the flow of the unit.
Possible flow switch settings:
Please contact Hitecsa for other possible flow options.

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.
Check 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.
Control the drainage of the installation and the tubes of the differential switch (if installed).
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.

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.

WARNING!
MAINTENANCE
It is advisable to do maintenance works every 1.000 operating hours as well as at the beginning of each cooling season.
Coils: At least once a year clean condenser coils with water and detergent and later dry with air at low pressure.
Never clean coil with wire brush.
Indoor fans: Check the direction of rotation of the fans, verify their carriers. Check the transmission elements and
the operating status.
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.
(Check the access to the condensates trays)
Refrigeration circuit: Check for oil or refrigerant leakage, noise and various system elements vibrations. Take
temperature and pressure readings and record it on the maintenance form.
Electrical circuit: Make sure that all electrical cables are properly tightened. Be sure that there are not faulty terminals,
contactors, etc. Take measurements of volts and amperes of each phase of every compressor and fan motor. Verify the
starting current. Check the operation of all relays, presostates and phase sequence relay (of scroll compressor).
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.
Heat exchanger: It is necessary, at least once a year, to clean the heat exchanger. The heat exchanger is cleaned by
circulating the cleaning liquid inside and if possible in the opposite direction. An acid mixture at 5% is used (5% oxalic
acid). Introduce the cleaning fluid through the exchanger. After this, the circuit should be cleaned with plenty of water to
remove traces of acid. Refill with new water and start up the unit.

COMPRESSOR LUBRICANT
Compressors with R-410A refrigerant use POE oils. Each compressor manufacturer is using different oil for its products.
The compressor or system cannot remain open to atmosphere more than 15 minutes.
Compared with the mineral oil used with R22 compressors, the synthetic polyester lubricants absorb 100 times more moisture.

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.
Should it be 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 SITE.

It is generally forbidden to carry out work on electrical live parts. Protection class of
the device when complete open is IP00! It is possible to touch hazardous voltages
directly.
The rotor is not protected against indirect contact neither by supplementary or
reinforced insulation nor by connection to safety-earth in accordance with EN 602041, therefore, must the system constructor provide protection by enclosure in
accordance with EN 61140 before the motor is connected to a power source. This
protection can be achieved for example by a guard grille (Product overview:
Application operational area and Installation: General).
When the motor runs independently due to air flowing through of if it continues to run
down after being turned off, dangerous voltages of over 50 V can arise on the motor
internal connections through operation of the generator.
The safe isolation from the supply must be checked 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.
The protective earth is conducting high discharge currents (dependent on the
switching frequency, current-source voltage and motor capacity). Earthing in
compliance with EN specifications shall therefore be observed even for testing and
trial conditions (EN 50 178, Art. 5.2.11). Without earthing, dangerous voltages can be
present on the motor housing.
Maintenance work may only be carried out by suitably qualified personnel.
Through use of capacitors, danger of death exists even after switching off the device
through directly touching the energized parts or due to parts that have become energized
due to faults. The controller housing may only be removed or opened when the power line
has been switched off and a period of three minutes has elapsed since switching it off.
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 external rotor motor, the external rotor turns during operation!

Do not switch off line voltage that the fan can start again!
Safe starting of fans is not guaranteed if it is started in reverse. If the application demands
safe starting, the machine manufacturer or owner must prevent reverse driving rotation by
suitable measures.
WARNING!

EC MOTOR FANS
Rotation caused by an air flow in the wrong direction
When the fan is stopped (no signal, no electrical supply, etc.), the control of the motor does not interfere if the fan rotates
in wrong direction (due to, for example, an air flow).
If you switch on the fan while it is rotating in the opposite direction, firstly the control will reduce the rotations in a controlled
way 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 turns in the opposite direction, the longer the control will need to reach the fan.
In the event that the fan rotates strongly in the opposite direction, it is possible that the control could not start the fan in the
proper rotation direction.
Information
Maintenance and repairs
Repairing works must be carried out by trained specialists only.
Wear safety shoes and gloves for handling.
Please observe the safety regulations and the protection rules of the worker by all maintenance and service work
(EN 50 110, IEC 364).
Before working on the fan, this must be disconnected from the power supply and secured against switching back
on!
Keep the airways of the fan free – danger because of objects dropping out!
No maintenance work at running fan!
Depending on the application and the transfer medium the impeller has a natural wear. Deposits on the impeller
can lead to imbalance and thus to damages (danger of endurance fracture). The impeller can disintegrate!
There is risk that the impeller could break because of the massive corrosion in case of transporting the product
in highly aggressive environment that could not be appropriate for it. The affected impellers for this type of
corrosion have to be replaced immediately.
Deposits on the motor, especially in the refrigerating wings and motor cavities, block an appropriate refrigeration
causing a premature disconnection of the motor. Therefore they have to be removed on time (cleaning).
Maintenance interval in accordance with the degree of contamination of the impeller!
Check the fan in regular periods in respect of mechanical vibrations (recommended every 6 months). Keep in
mind the limit values indicated on ISO 14694 and perform correction measures in case of exceeding them (e.g.
posterior balance by trained specialists).
Check the impeller, in particular weld-seams, for possible cracks.
Repair, e.g. by welding is prohibited!
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 change the bearing. Please contact our Service Department in
this case as for all other damage (e.g. to the coil or electronics).
Bolted-on wheels and / or wings may only be replaced by authorized manufacturer staff. The manufacturer shall
not be liable for damage caused through improper repair work.
It is necessary a regular inspection, with cleaning if it requires, to avoid the imbalance and obstruction of the
condensation water evacuation openings due to dirt.

Cleaning
Danger due to electric current
Clean the circulation area of the air fan.
Attention!
Do not use any aggressive, paint solvent cleaning agents when cleaning.
Make sure that no water gets inside the motor and the electronics (e.g. by direct contact with seals of motor openings),
observe protection class (IP).
It is necessary to check the free flow of the condensation water evacuation openings (if there are any) that are
appropriate for set up position.
In case of improper cleaning work 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 at least for 1 hour at 80 to 100% of maximum
speed before cleaning!
After the cleaning process, the fan must be operated for 2 hours at 80 to 100% of maximum speed for drying purposes!

Toxicity
Low
Contact with Skin
Liquid spatters can cause freeze burns.
It is impossible skin absorption could result dangerous. It can be slightly irritating.
Liquid has a degrease effect. Defrost with water the affected zones. Take off carefully
contaminated clothing, since it could have been sticked on the skin in case of frostbite.
Wash up affected zones plenty of lukewarm water. If irritations or blister formation
occur, get medical attention.
Contact with Eyes
Vapours cause harmful effects. Liquid splashes can cause freeze burns. Immediately
flush with an ophthalmic solution or with lukewarm clear water for at least 10 minutes.
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
R-410A: High concentration levels in the air can cause an anaesthetic effect,
including loss of consciousness. Exposure to extremely elevated dosages can be
unexpectedly lethal.
There is risk of suffocation at higher concentrations due to the oxygen content
reduction at the atmosphere. Remove victim to fresh air, keep it warm and at rest.
Supplemental oxygen if it is necessary.
If breathing has stopped or is laboured, give assisted respirations. In case of cardiac
arrest apply severe assisted massage. Get medical attention immediately.
Medical Attention
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
R-410A: 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.
Occupational Exposure Limits
R-410A: Recommended threshold: 1000 ppm v/v - 8 hours TWA.
Stability
R-410A: no specific data.
Conditions to Avoid
Do not use in the presence of high temperatures, flames, burning surfaces and
excess humidity.
Hazardous Reactions
A violent reaction can be occurred by contact with sodium, potassium, barium and
other alkaline metals. Incompatible substances: magnesium and more than 2%
magnesium alloys.
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 waterproof gloves and protective 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
R-410A: Not flammable in the atmosphere.
Cylinders
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.
