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.

A T T E N T I O N

Only authorised companies with the appropriate technical resources and suitably trained personnel may install the air conditioning unit.

C A U T I O N

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

D A N G E R

• 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.

C AU T I O N

• 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.

N OT E

• 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.

Installation manual

1.1 Safety instructions

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.

C AU T I O N

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

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.

D AN G E R

There should not be onlookers within a radius of 10 m of the unit when it is being hoisted.

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.

DB: Dry-bulb Thermometer; TH: Wet-bulb thermometer.

(2) Natural gas 2ND-H, G20, at 20 mbar and 15 ºC

(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.).

2. Supply air

Units are shipped with the lower duct openings covered.

For applications with downward airflow ducts:

1 In order to access the covers of the lower supply and return air ducts, remove the side panels of the

supply and return air compartments.

2 Remove and discard the lower duct covers.

3 Replace 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.

1 Replace the side panels of the supply and return air compartments with the set of accessory panels.

Make sure that the seal is air-tight.
