REFRIGERATION CONNECTIONS
Damages caused by an improper installation of the refrigeration connections between the
indoor and the oudoor units will not be covered by the warranty.
As a result of an improper installation, the following sources of problems can be derived:
- Entrance of air, water or any type of object or animal small enough.
- Pipes too thick or thin.
- Strangled or poorly welded tubes.
- Unfulfillment of the current local laws, for a bad layout, aesthetics of facades, etc.
In turn, the above aspects may have an impact on:
- Speed of the refrigerant inside the pipe too high or too low.
- Migration and no return of compressor oil.
- Noises.
- Explosive breaks of the pipes.
- Contamination due to refrigerant losses, that it is a greenhouse gas.
- Break of the solenoid valves or expansion valves.
- Rise of the electrical consumption and loss of performance and capacity.
- Reduction of operating limits, even to total inoperability.
- Breakage of the compressor or shortening of its operational life.
Guide for a proper installation of the refrigeration connections
1. Having determined a place and proper settlement of the units and the equivalent length of the route of the
refrigeration lines that connect them.
2. Calculate the pipes (diameters, lengths) and necessary couplings for the installation.
Use as a reference the document nº207682, REFRIGERATION LINES DESIGN (R410a).
3. Before beginning the installation check that the tubes have a clean and protected interior against the entry of
moisture. Use preferably long radius curves, do not produce throttles when handling the tube.
4. Installation of the pipes.
- Cut the tube with a cutter and then remove the burr and recalibrate the
diameter that has been reduced. Recalibrate with interior gauge or
expansion tong. Do not use file, knife, orany other tool non-specific tool that
could leave particles inside the tube.
- Reduce the number of welds that should always be strong type. In compliance with local laws, the welder must be
an approved employee. A bad weld can cause dirt inside the pipe, more or less explosive blowouts that can cause
third-party damage, pipe obstruction, refrigerant losses, etc. Remember that tubes to be welded must be clean of
oil and refrigerant. Through its inside must circulate dry nitrogen without pressurizing and have a good penetration
of the weld, heat the male pipe mainly.
5. The connection of the pipes to the machines can be threaded or welded. Check the tightness after the connections.
6. The most common threaded connections in small pipes are Flare type (flared). A bad flare will cause leaks and/or
blowouts. When doing the flare, it is essential to clean the burr of the tube well to avoid cracks, and do not leave
the pipe wall very thin and without consistency by tightening too much.

7. Make the vacuum to the installation and the units that are not charged with refrigerant. Once the vacuum pump
stops, check that the vacuum remains during 20 min., a proper vacuum will be at an absolute pressure of 2hPa
(2mbar) or less.
Humidity or water in the installation may cause irreversible damages to the compressor and other devices of the
circuit. Liquid water cools and boils when the vacuum reaches its vapor pressure and does not allow it to do so
correctly until it freezes, once the water is frozen it does not boil but it is much more difficult to remove and detect.
To avoid the freezing of the water, it is advisable to make a soft and prolonged vacuumand not make a fast vacuum
with very powerful pumps.
8. Open all the keys and load with the refrigerant indicated on the nameplate. If it is not included in the machine, add
the additional load due to the length and thickness of the pipes. Follow current legislation regarding who and how
can handle the refrigerant.
9. Check for leaks during the first operating hours and schedule maintenance after the first month.
OPERATION

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 leveled.
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 cable of the machine which MUST BE FREE OF VOLTAGE for this
operation.
Check that the drainage is not blocked.
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 he air filters are clean and correctly fitted.
Check the condition and placement of grilles, diffusers, air ducts, tarpaulins, etc.
START UP
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.
Due to the unit has frequency converters, it is essential that the protection be at least 300mA to prevent power
cuts caused by the activation of the circuit breaker.

OPERATION
INDOOR FAN TRANSMISSION ADJUSTMENT
Adjust transmission in such a way that the indoor motor consumption comes to its normal value.
If consumption is below nominal value it means that unit air flow is too low.
-To change fan speed:
1. Remove the belt. Move the motor along its track (or loosen the tensor set screw) in order to release it.
2. Loose the set screws of the motor pulley and turn the movable flange. Open or close depending on the needs
(Open: speed decreases).
3. Tighten set screws.
4. Place the belt in the pulley channel. The closure or opening of the pulley could void the size of the prior belt. In
this case, replace it for other belt of the same profile and with the appropriate length.
5. Tighten the belt by using tensor screw or sliding the motor, depending on the case.
-Align fan and motor pulleys:
1. Loose fan pulley set screws.
2. Slide fan pulley along the shaft and align it with motor by using a ruler in order to ensure that is parallel to the
belt.
3. Tighten fan pulley set screws.
- Adjust belt tension:
1. Loose motor mounting plate bolt and slide it.
2. Belt flexion millimeters is estimated by dividing S by 40.

OPERATING LIMITS
This unit is ready to operate properly with VRF (Variable Refrigerant Flow) or VRV (Variable Refrigerant Volume) outdoor
units. The operating limits will depend on the external units to which the unit is connected, and its Safety Systems.
MAINTENANCE
It is advisable to do maintenance works every 1.000 hours as well as at the beginning of each cooling season.
In case of leakage, any manipulation and/or recovery of refrigerant must be carried out by qualified and accredited
personnel in the current legislation. Add the quantity of oil that has been lost.
CONSERVATION AND CLEANING
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.
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.
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.
Fans: Check the direction of rotation of the fans, verify their carriers. Check the transmission elements and the operating
status.Before handling the fan, make sure that it is disconnected from the mains, even if it is already stopped and no one
can start during the intervention.
It is necessary a regular inspection of the unit. Its frequency must be in function of the working conditions to avoid dirt
accumulation in propellers, turbines, motors and grids that could entail risks and significantly shorten its life.
- In cleaning operations be very careful not to unbalance the propeller or the turbine.
- In all maintenance and repairing works, must take into account the current safety rules in each country.
Motors and fans do not need additional lubrication.
Drainage system: Verify condition and good operation of the drainage tray and drain trap.
Air filters: Clean filters after the first operating hours to collect possible light materials such as papers, porexpan pieces,
etc. excess of the installation and that have been dragged through air circulation. Clean again every 3 months (or more
often depending on how it works). The filter can be cleaned with soapy water, then rinse with clean water and let dry. If it
is necessary, replace the filters before they are in poor conditions (see current legislation, EN 779, UNE-EN 13053…).
FAILURES
FAN DOES NOT START
1. Check for loose or broken cables, in this case, replace or retighten them.
2. Check that the appliance is effectively in demand for cold, heat or ventilation only, otherwise check the outdoor unit.
3. Check the condition of the fuses or the power supply. Check the electrical wiring of the fan.
4. The mains voltage is too weak, in this case verify with the company.
Before performing any service or maintenance of the unit, it is mandatory to disconnect and lock
the system main switch to prevent anyone other than the technician from connecting the unit and
causing personal injury.
