6. Make sure that the extraction fan turns
clockwise as it slows down.
7. If it does (clockwise direction), shut the
fluff filter cleaning lid and consider the test
achieved.
8. If it rotates in the wrong direction (coun-
terclockwise), invert two of the three power
supply phases (after having disconnected
the appliance from the power mains by the
wall cutout switch), repeat the test.
Secure the back panel by the 4 relevant
screws.
WARNING!
IF FAN-CONNECTION PHASES ARE
INVERTED (INVERTED CYCLIC DI-
RECTION) FUMES EXTRACTION WILL
BE INSUFFICIENT FOR MACHINE OP-
ERATION.
IMPORTANT!
TO AVOID ACCIDENTAL PHASE IN-
VERSION, INFORM THE CLIENT, USER
OR LAUNDRY TECHNICIAN ABOUT
THE IMPORTANCE OF CORRECT RO-
TATING DIRECTION. THE GUARAN-
TEE DOES NOT APPLY TO DAMAGE
CAUSED BY INCORRECT INSTALLA-
TION.
5.5 CONNECTION OF EXHAUST
DUCTS (MODS. WITH ELECTRIC
AND STEAM HEATING).
The dryer is equipped with one exhaust-
duct port for (outer diameter 200 mm).
Fumes must be conveyed outdoors, to an
open and airy area; avoid long routes, bottle-
necks and U-bends that can get flooded with
condensate and consequently endanger suc-
tion through section reduction and chimney
corrosion.
WARNING!
Do not connect to flues exhausting burnt
fuel produced by gas, coal, wood or diesel
burners. The fumes produced by the dryer
must be kept separate from those of other
appliances. If the total length of the exhaust
duct exceeds 10 mt, provide for a conden-
sate collection outlet in the lowest point of
the exhaust system.
Keep a distance of 5 cm between the exhaust
duct and any flammable or heat-sensitive
object. The exhaust duct must not be made
of flammable material but of stiff metal.
Any screws or rivets used to couple pipes
must not project inside, as loose threads can
get caught in them. It is advisable to use
heat-resistant elastic bands, instead. As for
GAS-heated machines (EMG S) cfr. spe-
cific chapter.
5.6 AIR EXCHANGE
In the premises housing the dryer there
must be an air turnover that is proportional
to the capacity of the dryer itself, no matter
the heating type. Minimum air turnover per
dryer:
Dryer model EM S10
165 cm
Dryer model EM S15
165 cm
Dryer model EM S25
410 cm
Since this duct is intended to feed the appli-
ance, increase the pipe opening by 25%.
WARNING!
Mind curtains and protection grilles, as they
can reduce air exchange by 35/40%. Make
sure the opening area is sufficient to com-
pensate for any existing obstruction.
WARNING!
If in the same room other appliances take in
air and then release it outdoors (like extrac-
tion ironers, gas-heated boilers or dry clean-
ers etc.) it is necessary to increase the air
exchange area.
Maximum air consumption of dryer (with
drum empty):
Dryer model EM S10
870 m
Dryer model EM S15
870 m
Dryer model EM S25
1560 m
5.7 STEAM AND CONDENSATE
CONNECTION (FOR EMV S STEAM
MODELS ONLY)
The installation of steam-heated dryers (fed
on high or low pressure steam), must com-
ply with the national and local regulations
standards in force. The size of steam feeding
/condensate return pipes and shut-off taps
must be chosen according to steam pressure
and temperature and to the demand of the
appliances (steam consumption).Their di-
ameter must not be smaller than the dryer's
inlet and outlet couplings. Dryers usually
work on pressures comprised between 500
KPa (5 bar approx.) and 800 Kpa (8 bar
approx.). Read the rating plate and ascer-
tain the most appropriate operating pres-
sure. The appliance's steam inlet must be
connected to the steam electric valve sup-
plied (usually in the drum).
WARNING!
Mount a thin net filter, to avoid impurity
damaging the valve's membrane; also pro-
vide for a stopcock to enable servicing and
emergency actions.
The appliance's condensate outlet must be
coupled to a steam trap of appropriate size,
according to the trap/outlet distance and to
the features of the installation.
WARNING!
Downstream of the steam trap it is advisable
to install a check valve to prevent conden-
sate from flowing back in. A stopcock is
indispensable for maintenance and emer-
gency purposes, as well as a steam viewer to
ensure that the steam system is in good
working order.
Other components like bleeders, heat ex-
changers, condensate pumps, superheaters
or plenum chambers (expansion boxes) must
be included according to the characteristics
of the installation and of the dryer. Steam is

intended as saturated (containing no air).

Here is a list of the pros and cons of the most
2
widely-used steam traps:
5.7.1 THERMOSTATIC LIQUID-
EXPANSION STEAM TRAP
Does not retain condensate and consequently
does not freeze. High draining capacity
even when cold. Minimum distance be-
tween the dryer's outlet and the steam trap
2 m. Poor resistance to steam-pressure rush.
Flexible part does not stand corrosive con-
densate.
5.7.2 BIMETALLIC THERMOSTATIC
STEAM TRAP
In addition to the pros of the former type,
this steam trap provides higher resistance to
water hammer and to corrosive condensate.
It is not recommended for systems equipped
/h

with temperature-control devices.

5.7.3 FLOAT STEAM TRAP
Resists to load and pressure rush. Air in the
pipes is easy to bleed. Simple construction
facilitates maintenance. Instant condensate
draining. Float does not stand corrosive
condensate, water hammer events or steam
overheating. To be chosen according to
operating pressure.
5.7.4 REVERSE BUCKET STEAM
TRAP
Resists water hammer and overheated steam.
Corrosion-resistant as an optional extra.
Simple construction. Correct operation re-
quires perfect choice of size. Responds to
pressure and load rush more slowly. Con-
tinuous steam flow may occur in case of
pressure drop.
5.7.5 THERMODYNAMIC STEAM
TRAP
Size smaller than the former models. High
condensate draining capacity. Wide tem-
perature and pressure operating range. Ap-
propriate even with overheated steam and
corrosive condensate. Water-hammer resis-
tant. No freezing risk if the drain is installed
downwards. Inoperative when pressure is
below 0.3 bar or drain pressure is 80%
higher than inlet pressure.
WARNING!
Use components that are appropriate for
steam/ condensate pressure and tempera-
ture.
5.8 GAS CONNECTION: INSTALLA-
TION OF GAS-HEATED MACHINES
(EMG S)
WARNING!
It is forbidden to install gas-heated appli-
ances in environments housing perchlorate
dry-cleaners or machines using similar sub-
stances. This applies to all gas types.
