3.2. Location.
3.2.1.Transport and storage.
The machine must be transported always on its pallet and original packaging to guarantee its integrity.
Transport the machine to the definitive work place.
Remove the packaging and make sure that it has not been damaged during transport.
The dryer must not be installed or stored in an area where it will be exposed to water and/or weather.
If the machine has to be stored for a long time, cover it with its original packaging to protect it from external
agents and keep it in the optimum environmental conditions. It should also be disconnected from the
electricity network.
Once located in its definitive work place, remove the pallet to which the dryer is attached at the back of
the base with 2 bolts, which can be removed with an adjustable wrench or a flat No 13 spanner. Keep this
pallet with the original packaging for possible and future movements. Do not push the machine or clear
obstacles without the package, the machine runs the risk of deformation and malfunctioning.
The drum does not have anchorages for transport.
11

- LOCATION OF BOLTS 1 AND 2 - UNSCREW USING A FLAT NO 13 SPANNER
3.2.2.Location.
Install the machine in a big room to obtain efficient work conditions and to guarantee the sufficient ease of
movement of the workers using the machine.
The definitive position of the machine must allow its correct use. The distances indicated on the following
drawing must be observed to allow correct maintenance by the authorised staff.
Minimum operation and maintenance space: 59 1/8 in (1.5 m) at the front, 12 in (305 mm) at the top, and
the rest according to the scheme.
The distances from combustible construction machine to be at least: to the ceiling 12 in (305 mm), side
0 in (0mm), front 59 1/8 in (1.5 m) and rear wall (steam exit) 24 in (610mm).
12

3.2.3. Levelling.
- Do not anchor the machine, simply put it on a
flat and levelled surface. Position the four
adjustable feet supplied and found inside
the machine. A good levelled base is
important for correct operation.
Procedure:
-The machine must be supported on all four legs
so that it stands firmly on the ground and
does not rock.
- Adjust the 4 levelling feet to ensure the stability
and horizontality of the machine, checking it
with a spirit level. After levelling, fasten the
nut using a spanner.
- The maximum adjustment height at the height
of the levelling feet is 0.98in (25 mm).
3.3. Vapour extraction
3.3.1.Entrance of fresh air
To ensure optimum performance and to minimise the length of the drying cycles, an input of fresh
air is required from outside the room. The fresh air inlet should be behind the dryer.
The area of the fresh air inlet should be at least 4 times more than area of the air output pipe.
Note: The area of the fresh air inlet is equal to the area through the air is able to flow freely without
resistance from the bars or grille fitted across the entrance. Remember that the bars or vanes of the grille
often occupy a large portion of the area of the entrance.
13

3.3.2.Output pipe
Damp air should be channelled to the outside by connecting a pipe with a net diameter equal to the exterior
diameter of the steam output pipe. The extraction air should be taken outside the premises and must never
be connected to other fluepipes already in use for removing vapours from other fuels.
The location of these pipes must be within the limits established in the environmental heat legislation. A
pipe made of heat-resistant material should be used (302ºF (150 ºC)). Never leave the tube very near
inflammable materials or materials that are susceptible to deformation from excessive temperatures.
The tube must be smooth inside. It is important that there are no obstructions blocking the air flow or that
may result in a build-up of fluff (bolts, rivets,...). Systems for the regular inspection and cleaning of the
pipes should be set in place.
The output pipe should be as short as possible and there should be a slope of 2% towards the outside in
the horizontal sections, to prevent condensation from returning to the machine.
Although the appliance has two dryers which operate independently, there is only one steam output.
The machine has a non-return valve which prevents steam from passing from one drum to the other. The
steam output can be connected directly upwards (advisable) or, if this is not possible, using a 90º (1.57
rad) L-bend to the back.
Option of the 90º (1.57 rad) L-bend Option of the vertical output
14

Note: For installations with longer lengths of piping and/or more bends, please refer to the technical
service. It may be necessary to enlarge the diameter of the piping or even to install an auxiliary vacuum
in the installation.
Each machine should preferably have an independent steam outlet. If this is not possible:
•Always make connections in Y. Never in T.
•Increase the area before the connection so that the final area is equal to the sum of the two previous
areas.
IMPORTANT
•To extract the steam, do NOT use plastic or aluminium paper hoses. We recommend a rigid metal
pipe. The diameter is Ø8 in (200 mm.)
•Check that the existing installation in the premises is clean and does not contain fluff from other
dryers.
•Use the fewest possible number of L-bends.
•To join the different L-bends and pipes, use aluminium paper adhesive tape. Avoid fastening
these with sheet screws as this will result in a build-up of fluff on the interior.
•The pipe, as it passes to the exterior or through cold zones, should be insulated to avoid
condensation as this would result in a build-up of fluff on the inner walls of the pipe.
The output pipe should be as short as possible. It is advisable that it has a slope of 2% in the direction to
the outside in the horizontal sections, to prevent condensation from returning to the machine.

3.4. Electrical connection
Although the appliance has two dryers which operate independently, there is only one electric connection.
Make sure that the characteristics of the available power supply correspond to those of your dryer,
indicated on its identification plate, and that the cable section and other line accessories can supply the
necessary power.
The machine leaves the factory with the complete electrical installation, therefore, it will be sufficient to
remove the cover located at the rear of the tumble dryer and connect each terminal to phase L1, neutral
N and the ground connection at the terminals connection or main switch.
A circuit breaker and differential switch MUST be inserted between the wiring and the mains, and the
sensitivity of the differential switch must be 300 mA. Higher sensitivity, for example 30 mA, common in
domestic installations may cause operating anomalies in the machine.
Connect the phase and the neutral in the main switch and the earth protection in the earth connection next
to the main switch according to the following table (section in mm2).
Correct earthing is essential to guarantee the safety of users and correct operation.
The dryer, when installed, must be electrically grounded in accordance with local codes or, in the
absence of local codes, with the National Electrical Code, ANSI/NFPA 70, or the Canadian Electrical
Code, CSA C22.1

3.5. Connection to gas (only gas models)
Although the appliance has two dryers which operate independently, there is only one gas inlet.
All gas models are prepared to work with propane gas (LPG) or propane
gas and with a burner pressure and a gas according to the one on the nameplate. Check that the type of
gas and the pressure value in the burner correspond to the rating plate. If not, you should consult with
the provider.
The dryer has spare injectors and a new rating plate in case it is necessary to install the appliance to
operate with a different gas group, allowing to install the machine in many countries with the main fuels.
In the tables on the following page you can check, for each type of gas and in different countries, the
diameter of the injector and the burner pressure suitable to operate correctly.
A listed connector in compliance with the Standard for Connectors for Gas Appliances,
ANSI Z21.24 • CSA 6.10, shall be used to connect the dryer to the supply piping.
The gas inlet connection is ½ " (20.95mm). Do not connect a tube with an inner diameter lower than that
required by the machine. Take into account the consumption to ensure the necessary flow. See table in
section 2. A minimum 1/8-in NPT plugged tapping, accessible for test gauge connection, must be
installed immediately upstream of the gas supply connection to the dryer.
For all types of gas it is necessary to install a manual valve and a gas filter, and only for LPG gas install
a pressure regulator. Make sure that dirt does not enter the valve during piping.
17

Once the installation is completed, it is necessary to make the following DRIP TEST:
Turn on the burners. With the help of a brush, apply soapy water to the gas inlet joints. Check if bubbles
form. If so, disassemble the valves, clean them and reassemble them. Do not use a soap that is too
corrosive. It is also possible to perform the test with a special product designed for it.
The dryer and its manually operated appliance main gas valve must be disconnected from the
gas supply piping system during any pressure testing of that system at test pressures in excess
of 1/2 psi (3.5 kPa).
The dryer must be isolated from the gas supply piping system by closing the equipment shutoff valve
during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2
psi (3.5 kPa)
INSTRUCTIONS FOR CHECKING THE INLET GAS PRESSURE.
