3 TRANSPORT, HANDLING AND

STORAGE

3.1 Storage

During transport the air conditioner is

protected by its cardboard packaging. The

conditioner must be stored indoors in a

horizontal position in a dry, ventilated area.

The type of packaging allows up to 5 (five)

conditioners to be stacked on top of each

other.

Do not turn the

package upside-down. The right way up is

indicated by the arrow on the packaging ( ↑ ).

Stacking more than five

packaged air conditioners can damage the

conditioners themselves and put

personnel at risk of injury.

3.2 Weight

Weight without packaging:

SILENT 7012H 40,5 kg

3.3 Handling

Packaged air conditioners can be moved

using standard means of lifting and transport.

The packs have spacers for insertion of

transpallet forks.

Always observe safety

and accident prevention regulations when

lifting and transporting. Use only lifting

and transport gear of a load bearing

capacity greater than the weigh to be

lifted.

4 INSTALLATION

4.1 Preliminary Information

Before installing the

conditioner you must read these

instructions thoroughly to prevent errors.

Incorrect installation

can irreparably damage the air conditioner

and compromise user safety.

European Directive 89/392 states that the

manufacturer cannot be held liable for poor

air conditioner performance and/or safety

should the air conditioner fail to be installed in

observance of the information provided in this

manual. Moreover, the manufacturer cannot

be held liable for any resulting injury or

damage.

Installation must only be

carried out by qualified or specially

trained personnel.

4.2 Installation

Before installing the

unit all the electrical connections on the

vehicle must be disconnected.

• Positiv battery lead

• Generator (where available)

• Outdoor power shoket

Failure to observe the

above can lead to power discharges.

Before climbing on top of

the vehicle check that the roof is designed

to be walked on. Check with the vehicle

fitter. If it is not, a scaffolding-like

framework will be required.

To ensure proper air conditioner installation it

is essential that you first check whether the

roof is able to support its weight; if it is not the

roof must be reinforced.

Select a fairly flat, horizontal, central area of

the roof and check that there are no interior

obstacles which might obstruct diffuser

attachment [fig. 1 ref. 4] or the outflow of

cool air from the adjustable vents [fig. 1 ref.

5].

Min. dist. from any obstacles 300 mm

The air conditioner may be installed in one of

two different ways:

• by using a ventilation aperture already on the

vehicle (ventilation port)

• by opening a new hole.

•

4.2.1 Using the existing ventilation port

This solution is practical as long as the port

size is 395 x 395 mm [fig. 2 ref. A]. Figure 2

gives the dimensions of the air conditioners

and the holes needed for installation.

Proceed by removing the screws that fix the

port to the roof and then removing the port

itself. Scrape off all the sealing material left

around the rim of the opening [fig. 3 ref. 1]

and putty screwi holes and joints with silicon

or other products available from specialised

shops [fig. 3 ref. 2].

All waste materials

(glue, silicon, seals) must be placed in

special containers and taken to official

waste disposal centres.

4.2.2 Open new hole

Choose a central area of the roof between

two spars and trace the outline of a 395 mm

square with a felt-tip pen

[fig. 2 ref. A] [fig. 4 ref. 1].

Cut the new opening in the roof carefully with

a saw: be careful not to cut any electrical

wires [fig. 4 ref. 2].

Use protective

gloves and goggles before using electrical

tools or handsaws.

Fix a reinforcement frame around the opening

[fig. 5].

4.2.3 Power lead 12 V dc

To power the air conditioner it is necessary to

connect it up with a red-black power lead

having a minimum cross-section of 25

. One end of the lead must be

connected to the “+ and –“ battery terminals

while the other end must reach the air

conditioner body on the roof [fig 6].

Before making any

electrical connections always make sure

the power is disconnected inside the

junction box and that the wire ends are

not live.

To ensure good insulation under all

possible conditions electrical wiring must

be properly sheathed.

4.3 Positioning the conditioner

Before positioning the air conditioner on the

roof it is necessary to lay a sufficient amount

of slow-drying sealant around the rim of the

aperture.

Bring the air conditioner onto the roof [fig. 7

ref. 2] and, without scraping it, position it over

the 40 x 40 cm opening previously lined with

sealant. Correct alignment of the air

conditioner on the roof will provide a view -

from inside the camper - of the 4 threaded

fixing seats. The arrow in fig. 7 indicates

direction of forward drive.

The framed support

seal perimeter must be aligned with the

edge of the hole [fig 7 ref. 1].

Working from inside the camper, shift the air

conditioner until the four fixing threads are

aligned with the square opening of the hole

on the roof.

Insert, from inside the camper, the metallic

frame: align the seat of the diffuser with the

rectangular air outflow vent on the upper

section [fig. 8 ref. 1], then fix it in place with

the four screws [fig. 8 ref. 2].

Tighten the screws so that the original

thickness of the seal is reduced by a third.

Do not squeeze the

seal excessively. It must not be squeezed

any shallower than 20 mm [fig 7].

Excessive seal squeezing can damage the

base of the air conditioner, compromise

the airtight seal and cause loud noise

during use.

Check that the power lead is not

excessively long as it could obstruct the

intake grille.

4.4 Connecting the power lead 12 Vdc

Link the two “+ –“ leads to the supplied

connector.

CAUTION: DO NOT INVERT POLARITY.

Fit connector “A” onto connector “B”

4.5 Installing the diffuser

Remove the two airflow direction adjuster fins

from the diffuser.

Position the diffuser [fig. 9] momentarily and

mark the 6 hole drilling points that correspond

to the attachment points on the aluminium

duct. Drill the holes with a 3 mm bit.

Connect the panel connector [fig. 10 ref. 1]

and the temperature sensor connector [fig.

10 ref. 2] and fix the diffuser to the aluminum

duct with the 6 self-tapping screws [fig. 11

ref. 1].

Re-insert the two fins.

Note that the air conditioner starts

working 3 minutes after being switched

on.

5 ISTRUCTION FOR USE

5.1 Introduction

The manufacturer

cannot be held liable for damage caused

by improper use of the air conditioner.

The SILENT air conditioner consists of four

main parts:

• compressor, which circulates the coolant

gas through the system;

• condenser, which cools the coolant by

changing it from a gaseous to a liquid state.

• injector, housed in the evaporator, which

changes the coolant from a liquid to a

gaseous state;

• evaporator, which, cooled by the change of

state of the coolant, cools the air passing

through it. Air temperature is adjusted via a

thermostat and tip in atmosphere.

The SILENT provides cold air during the

summer months and hot air in winter.

If the vehicle has been left in the sun for

some time it is good practice to open

windows and doors before starting the

conditioner so as to release the build up of

heat in the interior; once indoor temperature

matches outdoor temperature close the

windows and doors and start the air

conditioner. Subsequently, only open doors

and windows when necessary.

if the conditioner is made

to run at 12 Volts, with the vehicle parked,

remember that a good 100 Ah battery

completely charged will last for no more than

one hour. If the battery is not in a good

condition, or is smaller, this time will diminish

drastically. In any case, we suggest you do

NOT use the battery until it runs out, as this

would damage it irreparably and make it

unusable in the future.

5.2 Preliminary checks

Before switching on the air conditioner for the

very first time:

• Check that condensate drainage holes are

unobstructed.

• Check that power voltage are as indicated in

the previous section.

• Check that air flow through relative ducts and

vents is unobstructed. To ensure maximum

efficiency always keep external ventilation

grilles clear.

5.3 Control panel (fig 12)

Fan speed key [fig. 12 ref. 1]

Thermostat adjuster knob [fig. 12 ref. 2]

On/off switch [fig. 12 ref. 3]

Menu key [fig. 12 ref. 4]

Display [fig. 12 ref. 5]

5.4 Switching on

To switch the air conditioner on

press the on/off key [fig. 12 ref. 3]

and at the same time, the display is

active.

After switching on the

conditioner there is a 3-minute pause

before the compressor is started and cold

air outflow begins.

The conditioner

features an automatic thermostat with a

minimum working temperature of 16°C (+/-

1°C). Below this temperature the

thermostat does not enable the

compressor: this prevents ice forming

inside the unit. Fans and the heating

function remain enabled.

5.5 Display [fig.12 rif.5]

The display shows the temperature setting

(SET). Temperature is set via the thermostat

knob [fig. 12 ref. 2].

Press the menu key

[fig. 12 rif.4] on the display and the

ambient temperature (TA) inside the

vehicle is displayed for a few seconds.

The display then reverts to the

temperature setting.In addition to

temperature, the Display [fig. 12 ref. 5]

also shows the following:

5.6 Setting fan speed

Press the speed key [fig. 12 rif. 1]

If pressed once the display shows the fan

speed setting: this is shown for a few

seconds before the display reverts to ambient

4 1

temperature (TA). To modify fan speed keep

pressing the key: fan speed will be adjusted

according to the following sequence

In which F11, F12 and F13 are the three fixed

speeds and AUT is automatic speed. F11

indicates slow fan speed, F12 medium speed

and F13 high speed.

If one of the three fixed speeds is set the

control panel always activates ventilation at

that same speed. If, instead, fan speed is set

to AUT, the control panel step by step

[fig. 12] automatically

selects the most

appropriate fan speed in consideration of the

temperature setting and the temperature in

the vehicle interior.

5.7 Thermostat [fig.12 rif.2]

Rotate the thermostat to set the desired

temperature on the display.

The control panel [fig. 12] allows automatic

control of temperature in the vehicle interior.

If, for example, we set a temperature of 25°C

the conditioner will produce cold air as long

as the temperature inside the vehicle is

higher than 25°C.

When the temperature inside the vehicle

(ambient temperature) is lower than the

setting (25°C) the conditioner activates the

incorporated heater to produce hot air..

Correct use of the thermostat is very

important. If you set a temperature much

lower than outdoor temperature (more than

8°C lower) you run the risk of falling ill

(catching colds etc.) and energy consumption

increases.

5.8 Cooling mode

- When this symbol is displayed constantly

the air conditioner is generating cold air.

- When the symbol flashes, the air

conditioner is restoring gas pressures inside

its interior and will start producing cold air

after 3 minutes.

- When neither the symbol not the heating

symbol appear this means that:

a) a) ambient temperature has reached the

set temperature so the compressor is off

and only the ventilation fans are working.

b) temperature is less than 16°C and the

thermostat is set to minimum.

In this case, as long as ambient temperature

remains below the 16°C threshold, only the

fans work; the compressor is shut down.

5.9 Heating in heat pump

When this symbol is displayed the air

conditioner is generating hot air.

If the air conditioner shuts down when in

heating mode the fan will continue running for

several minutes to disperse the heat

accumulated inside the conditioner itself. The

fans then shut down automatically

The fixed symbol indicates that the

compressor is in function. To symbol blinking

indicates the stand-by function; during which

the compressor is firm and is in order to be

replaced in motion.

ATTENTION: The external temperature limit

of operation of the air conditioner is equal to

- 5 °C.

5.10 Switching off

To switch the air conditioner off press the

on/off key

[fig. 12 ref. 3].

5.11 Safety regulations

1. Always use properly earthed power sockets

with differential safety switches.

2. Never use the air conditioner near flammable

liquids.

3. Do not use the air conditioner for purposes

other than those stated by the manufacturer.

4. Do not modify or tamper with any parts of the

air conditioner.

5. Use only original spare parts.

6. Maintenance and repairs must only be

carried out by specialised personnel.

7. Installation must be carried out by qualified

personnel.

8. Keep children/animals away from the air

conditioner unit.

9. Do not insert fingers in ventilation

grilles/vents.

10. Do not insert objects into ventilation intakes.

11. If the air conditioner receives any hard

knocks have it checked by specialised

personnel before using it again.

12. In the event of fire never open the upper

cover of the conditioner: use homologated fire

extinguishers.

13. Do not attempt to put out a fire with water.

TROUBLESHOOTING

In the majority of cases poor air conditioner

performance is caused by incorrect use as

opposed to actual malfunctions. For example:

1. The unit is too small for the volume of air you

wish to condition.

2. The vehicle is poorly insulated.

3. The doors are opened too frequently.

4. There are too many people inside the vehicle.

5. Power supply voltage is less than 12 V dc.

There follows a list of the most common

problems with relative cause and solution..

Before inspecting for any

other causes of poor air conditioner

performance always check:

1. the power supply, which must never be

less than 12 V dc.

2. that intake vents are unobstructed.

3. that air outflow vents are open.

1) The air conditioner does not start

• check that the ON/OFF switch is positioned

to ON [fig 12 ref. 3].

• check that the socket is providing power:

check by connecting up any other appliance

or use a voltmeter..

2) The compressor does not start but the

fans are working

• ambient temperature is lower than 16°C.

• set temperature higher than ambient

temperature.

3) The condenser fan is not working

• check that the condenser fan is not structed

by foreign bodies.

4) Heating does not work

• check that set temperature is higher than

ambient temperature.

5) Air conditioner efficiency is poor

• if the air conditioner is working inefficiently it

is necessary to clean the air filter, condenser

and evaporator using specific detergents. It is

always advisable to clean the air conditioner

when it has remained idle for along period. If,

after cleaning the heat exchangers, the unit

still fails to regain its initial efficiency check for

coolant gas loss.

7 DISPOSAL

Always contact specialised workshops when

it is necessary to dismantle and dispose of

the air conditioner.

Waste materials must not be dispersed

into the environment: always take them to

authorised waste collection centres.

8 MAINTENANCE

8.1 Routine maintenance

All tasks requiring removal of air

conditioner covers must – as with

installation - be carried out by expert

personnel.

Before carrying out any work on the air

conditioner it is essential that you

disconnect the 230 V power supply and

wait for all its component parts to cool

down.

Remove the external cover and spray a

suitable detergent onto the heat exchangers

(evaporator and condenser) and then rinse to

remove impurities.

1. Check that the condensate drain holes

are unobstructed.

2. Check that the seals are in good condition

and there is no infiltration of water into the

vehicle.

3. All traces of oxidation must be removed

and metallic parts coated with a suitable

paint.

4. Check that wiring insulation is in good

condition and eliminate any traces of

moisture.

5. Check that all screws are properly

tightened.

6. If the vehicle is garaged for the winter

disconnect the air conditioner from the

power socket.
