SAFETY PRECAUTIONS
•Installation and maintenance of air conditioning equipment can be dangerous because the
system is under pressure, because some of its elements have high temperatures and
include electrical components.
•Only qualified and trained service staff should install,commission and carry out
maintenance works. Unqualified staff should only carry out basic tasks such as cleaning
and replacement of filters, etc.
•In every visit, all precautions should 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 codes.
•Use safety glasses, work gloves and any other safety accessory necessary.
•For brazing operations use a quenching cloth and have at close distance a fire extinguisher.
WARNING!
Before starting installation, service or maintenance, turn off the main power switch in order
to avoid electrical shock that may cause personal damages.
•When repairing the unit, use only original spare parts and install them properly in the
same position where old parts were placed.
These units are designed to work with 100% recirculated air. The installation with 100% outdoor air
is prohibited. See application limits.
• Do not install the unit in explosive atmosphere.

RECEPTION
INSPECTION UPON RECEIPT
•Units are delivered with special protective packing; therefore when it arrives, please
inspect it carefully to check that no damage has occurred during transport and that the
unit has been supplied complete with all parts specified in the order. If any damage is
found, immediately file a claim with the transport company.
•Verify the correct voltage of the nameplate and make sure it’s 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.
•When lifting the unit, make sure that it’s balanced and stable; bear in mind that the
heaviest part is where the compressor is installed.
•Check minimum length of wire raising (Fig.1)

STORAGE
If the equipment is going to be stored please follow the instructions below in order to avoid
damages, corrosion or deterioration:
•Keep the unit away from direct sunlight, rain, sand, wind or temperatures above 50ºC
•Storage temperature: maximum 50ºC, minimum -10ºC
•Maximum humidity: 90%
INSTALLATION LOCATION
•Check if the base is able to support the weight of unit during operation.
•Reserve a minimum service area according to Fig. 2.
•Choose a place free of dust or any other foreign material that could clog or damage the
condenser coil. The location should also be a place that cannot be flooded.
•Consult and respect all regulations concerning installation of air conditioning systems.
•Check if sound waves do not disturb anyone.

BEFORE START UP
•Check the following points:
oWires are well tightened.
oPanels are firmly secured with screws.
oThere are no oil or refrigerant leaks.
oThe unit is correctly levelled.
oThere is enough space for service and maintenance.
oDrainage is not blocked.
oCrankcase heater has been working at least 24 hours prior to the start-up.
oAir filters are clean and correctly mounted.
oGrilles, air diffusers, air ducts and flexible connections are in good condition.
oElectrical power source is in accordance with what is said in the nameplate.
oFans rotate in the right direction.
.
START UP
•Start up should be performed by qualified technical people.
•Use a start up check list: record inlet and outlet temperatures and pressures, outdoor air
temperature, volts and amps of each compressor and each fan motor, suction and
discharge pressure of each compressor.
•Use a similar check list for service and maintenance works.
•Remember that after 4 hours of operation, it is necessary to clean the filters.
•Monitor at least cooling cycle operations.

•Main power supply of the unit should agree with the data shown on the nameplate.
HITECSA will not be held responsible for damages resulted from non observance of the
above.
•Always use the wiring diagram sent with the unit to make electrical connections.
•Check that the crankcase heater has been working at least 24 hours prior to the start up of
the unit.
•Current supply should be within 10% of Volts and Amperes indicated on the unit
nameplate.
•Do not operate the unit at different current from that shown on the unit nameplate.
•The installer should put line protection elements in compliance with current legislation.
•The interconnecting wires should be protected with a tube or put inside a groove channel.

DRAINAGE
•Indoor drainage (of condensate water) has a /4” MPT connection.
•Condensate drain line diameter should be equal or larger than the unit connection
depending on line length and general building configuration.
•Drainage line should have a minimum inclination of 2% for proper water evacuation.
•When drainage line is exposed to temperatures below 0ºC, it is necessary to provide
thermal insulation or electrical heating wire to avoid water freezing and tube damages
• It is advisable to install a trap with proper dimensions.

REFRIGERANT CHARGE
WARNING!!!
Never use oxygen to carry out leak tests. Oxygen reacts violently when in contact with oil
and could cause an explosion resulting in damage, personal injuries or even death.
•Should it be necessary to add or recover refrigerant, do it always in LIQUID phase, never in
gas or vapour phase since this would cause wrong mixing conditions.
•Due to its high pressure and quick evaporation, refrigerant R410A cannot be kept in liquid
phase inside charge cylinder because bubbles would form, making reading difficult.
WARNING!!!
If it’s necessary to make welding operations, you must fill the circuit with dry nitrogen.
Combustion of R410a refrigerant generates toxic gases.
•Repair immediately any refrigerant leak.
•Never overcharge the system.
•Never use compressor as a vacuum pump.
•If symptoms of refrigerant loss appear during operation, it’s necessary to carry out a leak
test. Leak detectors usually employed with CFC and HCFC cannot be used with R410a, due
to chlorine in its composition. A leak detector for R1 4a may be used but the sensibility
will be lower (when sensibility is 1 for R1 4a, it falls to 0,6 for R410a).
•To find small leaks, you will need a detector for HCF. Sensibility for R410A is approx. 2
grams per year.
•If a gas leak is found, it will be necessary to remove and completely recover the refrigerant
charge. Pressurize the system with dry nitrogen. If no leakage is detected, then do the
vacuum and charge again with refrigerant.

MAINTENANCE
WARNING!!!
Before performing any service or maintenance operation, turn off the main power switch of
the system to avoid any personal injuries. Block the power switch so that nobody other than
a qualified technician can switch on electrical power.
•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, then dry
with air at a pressure of 600 kPa. Never clean with wire brush.
•Fans and motors: adjust transmission belt at least twice during the first month of
operation and then check every 1.000 hours. Fan and motors do not need additional
lubrication.
•Drainage system: verify condition and good operation of the drainage tray. Make sure
that holes at the base of the unit are not blocked so that evacuation can be properly
done.
•Refrigeration circuit: check for oil refrigerant leaks, noises or system’s vibrations. 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,
terminals- are properly tight. Record the measurements (volts and amperes) of each
compressor and fan motor. Verify the starting current. Check the good operation of all
relays, pressostats and phase sequence relay of Scroll compressor.
