Installation manual

1.1 Safety instructions
This document contains the necessary information for the safe and efficient transportation, assembly
and installation of the air conditioning unit. This guarantees the condition of the unit and its operating
safety.
Only an authorised company may assemble the air conditioning unit.
ATTENTION
Only authorised companies with the appropriate technical resources and suitably trained personnel may
install the air conditioning unit.
CAUTION
The specialists responsible for installing the air conditioning unit must make sure they have all of the
information and knowledge required to correctly install, test and deliver the unit. Johnson Controls Inc.
shall not be considered responsible for any damage caused by installation of the unit that is no consistent
with that described in this document or others specifically provided with the unit.
During regular unit installations, the fitter must pay special attention to certain situations in order to pre‐
vent injuries or damage to the unit.
Situations that could jeopardise the safety of the fitter or that of others nearby or that could put the unit
itself at risk are clearly indicated in this manual.
A series of special symbols are used to clearly identify these situations.
Pay careful attention to these symbols and to the messages following them, as your safety and the safety
of others depends on it.
1.2 Icons used in this document
DANGER
•The text following this symbol contains information and instructions relating directly to your safety
and physical wellbeing.
•Not taking these instructions into account could lead to serious, very serious or even fatal injuries to
you and others in the proximities of the unit.
Information can also be found on safe procedures during unit handling. This will help reduce the risk of
accidents.
CAUTION
•The text following this symbol contains information and instructions relating directly to your safety
and physical wellbeing.
•Not taking these instructions into account could lead to minor injuries to you and others in the prox‐
imities of the unit.
•Not taking these instructions into account could lead to unit damage.
Information can also be found on safe procedures during unit handling. This will help reduce the risk of
accidents.
NOTE
•The text following this symbol contains information or instructions that may be of use or that is worthy
of a more thorough explanation.
•Instructions regarding inspections to be made on unit parts or systems may also be included.

1.3 Instructions for storage, transport, loading and unloading of
the unit
Delivery inspection
The unit should be carefully inspected for visible damage or abnormalities as soon as it is received.
Any abnormalities or damage to the unit should be communicated to both the transportation and insur‐
ance company in writing.
Storage instructions
The unit should be stored in a place suitable to the purpose (warehouse or similar), protected from the
weather, water, humidity and dust.
Cover the unit with a canvas of a suitable size.
The unit should be appropriately protected from knocks and dust, ensuring the protective parts it was
supplied with remain in place. Where these are not in place, establish the necessary protection and
barriers to keep vehicles or fork-lift trucks away.
Transport, loading and unloading of the unit
The units should only be handled by personnel from the company responsible for their installation.
Transport of the unit should be in such a manner that no damage is caused by faulty or inadequate
mooring to the bed or body of the vehicle.
Where necessary, protect all of the edges of the unit against knocks and scratches and moor it to the
bed or body of the vehicle using suitable textile belts or slings to keep it perfectly still.
Loading and unloading the unit from a truck or trailer should be on flat, solid ground using an appropriate
crane with sufficient capacity.
CAUTION
It is strictly prohibited to use fork lifts to load, unload, or handle the unit.
1.3.1 Disposal of packaging
The packaging is recyclable. Dispose of it in the appropriate place or take it to an appropriate collection
centre. Respect the regulations in force for this type of waste in the country where the unit is being
installed.
Packaging remains must be correctly disposed of. Improper disposal of packaging generates environ‐
mental problems that affect human life.
1.3.2 Lifting points
The points designed for lifting the unit are situated in
the beams at its base. -arrows-.
Before hoisting the unit, check that the cables or
slings are firmly hooked to these points and make
sure the crane and the cables or slings are capable of
lifting the weight.
Installation manual 1
Instructions for storage, transport, loading and unloading of the unit 1.3
3

Place separators -1- above the unit to prevent the ca‐
bles or slings from touching it.
Attach guide ropes so that that the unit does not rotate
freely.
The cables or slings should be long enough to form
an angle of over 45º to the horizontal plane. Hoist the
unit keeping it in a horizontal position.
DANGER
There should not be onlookers within a radius of 10
m of the unit when it is being hoisted.

1. Direct sunlight on the unit should be prevented when temperatures are higher than 43ºC. If placed under some kind of protective cover, the cover should not interfere
with the flow of outdoor ventilation.
2. The gas heating units (ARG/ARD) are only appropriate for use with gas. In LPG (Liquefied Petroleum Gas, propane) installations, it must be ensured that in no case
should gasoline in liquid form reach the gas group.

(3) Propane gas, G31, at 37 mbar and 15 ºC.
(4) The air flow should be regulated so as to increase temperature within the specified limits. Units with optional high power burners should have a minimum air flow of
10000 m3/h.
Note: The gas units are shipped ready to operate with natural gas. A conversion kit can be used to convert them to propane gas (L.P.G.).

Units are shipped with the lower duct openings covered.
For applications with downward airflow ducts:
1In order to access the covers of the lower supply and return air ducts, remove the side panels of the
supply and return air compartments.
2Remove and discard the lower duct covers.
3Replace the side panels of the supply and return air compartments. Make sure that the seal is com‐
pletely air-tight and check that the screws that fasten the panel have their corresponding o-rings.
For applications with sideways airflow ducts:
Flanges for connecting the side ducts are included in an accessory kit.
1Replace the side panels of the supply and return air compartments with the set of accessory panels.
Make sure that the seal is air-tight.
