2.0 INSTALLATION
2.1 AUTHORISED PERSONNEL
The air conditioner shall be installed onto the vehicle -i.e.
camping-cars, caravans, motorhomes, only and
exclusively by skilled technicians or workshops, authorized
by W.T.A.
According to the vehicle dimensions and to the real air
conditioning needs one or more units can be installed.
If the installation is carried out by non-authorized
technicians or workshops, W.T.A. disclaims any
responsibility for the unit safety and efficient running
according to the M.D. 89/392/EC.
DANGER
The instructions given in sections 2.2 are addressed
to qualified technicians only.
2.2 MOUNTING THE AIR CONDITIONER
BLIZZARD air conditioners can be installed on openings
with following sizes: 35x35 cm. up to 40x40 cm max. It is
possible to use an existing air inlet or drill a new one. In
such case, make sure that the roof can tolerate the air
conditioner weight and, in case, stiffen it suitably.
Remove the skylight cover (fig. 3).
Carefully clean the surfaces around the installation
opening, remove any waste, and fill any surrounding hole
2
or deformation with filler or silicone (fig. 4).
Set the supply mains with 1.5 sqmm section (AC 230V -
50 Hz) close to the roof opening .
Drill a hole on the diffuser surface close to the supply
cables (fig. 5).
Lay the diffuser on the opening centre, paying attention
that the adjusting grate position corresponds to the running
direction (check as well the diffuser correct position from
the vehicle interior).
Apply some silicone around the diffuser and between
diffuser and roof (fig. 6).
Secure the diffuser to the roof by means of the screws
provided, then drill some ø 5 mm holes close to the prearranged seats and apply silicone to the diffuser external
edge.
Fit the self-tapping screw metal stiffeners into their relevant
seats.
Lay the supplied seal around the diffuser edge, paying
attention that the seal joint is opposite to the running
direction (fig. 7).
Connect the wires to the switch by means of the “faston”
provided, and the ground wire by means of a terminal (fig.
8).

3.0 INSTRUCTIONS AND RUNNING
IMPORTANT
The firm does not take any responsability for damages
arising from malfunctionings of the air conditioner.
3.1 AIR CONDITIONER DESCRIPTION AND
RUNNING
The air conditioner consists of an A.C.-power supplied
compressor, which sets the liquid under pressure in a
suitable battery (coil) and heats it. Subsequently the liquid
is conveyed to a second low pressure “battery” where it
expands, absorbs heat and refrigerates the air coming
from the radiator.
Air is conveyed to the vehicle through the special fan at
adjustable speed.
Temperature can be adjusted by the suitable thermostat.
Latter can supply fresh and dehumified air in summer and
warm air in winter (if fitted).
3.2 MACHINE SAFETY
CAUTION
Always make sure that cables are not power supplied
before connecting them.
Set the closed air conditioner on the roof. Open the upper
cover and connect the lower part to the previously mounted
diffuser (fig. 9), always taking into account the running
direction.
Connect the diffuser to the air conditioner using the
connectors provided (fig. 10).
Secure the air conditioner to the diffuser by the six
supplied screws (fig. 11).
CAUTION
Secure the base to the vehicle roof using the six
screws shown in fig. 11. The remaining holes must be
free to allow the condensation water to drain out.
For a safe utilization of the air conditioner, some checks
shall be carried out before switching it on:
• Check that the water trap holes are not clogged.
• Check that voltage and frequence given in the
identification plate comply with the values required by
the local regulations/provisions.
• Check that neither the air inlet nor the air outlet and
circulation inside the ducts and the air inlets are
hindered.
DANGER
• Keep flammable substances like petrol, paints,
solvents, etc. away from the air conditioner.
• Do not touch the air conditioner or its connections
with wet hands.
• Any check of the electric parts shall be made with
engine stopped and by authorized technicians
only.
Carefully fix the cover (fig. 12)
Make sure that the fan rotates troubleless (fig. 13).
Then fix the frame within the vehicle by using the predrilled
holes as reference point (fig. 14).
The air conditioner is manufactured according to the
safety rules given in the Conformity Declaration.

4.0 HOW TO USE THE AIR CONDITIONER
4.4 UNAVOIDABLE DANGERS
4.1 STARTING AND FUNCTION SELECTION (fig. 14
and 15)
1) Ambient thermostat.
2) Double-way switch.
3) Main switch 0/1.
4) Warm/cold switch (if fitted).
To switch the air conditioner on, push the switch “3” to pos.
1.
4.2 INTERNAL TEMPERATURE ADJUSTMENT
The machine is fitted with an ambient thermostat operated
by a blue/red knob. To get the required temperature, it is
enough to set the chosen colour to the fixed reference
point (pos. A fig. 16). By nearing the knob blue area to the
reference point (pos. A fig. 16), the air temperature
decreases, provided that switch (pos. 4 fig. 14) is set to
"cold".
By nearing the knob red area to the reference point (pos.
A fig. 17), the air temperature increases (if fitted), provided
that switch (pos. 4 fig. 14) is set to "warm".
IMPORTANTE
The heating function (if fitted) cannot replace the
heater of the whole vehicle; it is only designded to
warm the ait in cool days.
4.3 AIR CONDITIONER STOPPING
Push the switch “3” to pos. "0" for the unit stop.
DANGER
CAUTION
Never introduce your hands or other objects within
the air inlet openings.
4.5 IMPROPER USE
The air conditioner shall be installed by skilled and
authorized technicians only according to the
Manufacturer’s instructions.
The air conditioner shall be used only and exclusively for
the purposes for which it has been designed and
manufactured.
4.6 TROUBLESHOOTING
We have listed below some problems which may occur,
along with their respective causes and possible solutions.
In the case of problems which are not listed below, please
seek advice from an authorised after-sales service centre.
We wish to point out that most of the claims we receive are
due to improper use rather than to faults of our equipment,
and namely:
• Too large vehicle.
• Vehicle walls are not insulated.
•
Vehicle with too large windows (in such case, we
recommend to use heavy and insulating blinds).
• The vehicle is a camper with a walk-through driver
compartment.
• Doors are frequently opened.
• Air comes in from the openings.
• Too many people inside the vehicle.
• Voltage less than 230V.
Never obstruct the air inlets and outlets.
The air conditioner fitted compressor runs during the
refrigerating phase of the unit. If switched off and on at
once, it might get damaged. Therefore, it is very important
TO WAIT ALWAYS 3 MINUTES AT LEAST before
attempting to switch it on again.
IMPORTANT
Always use ground plate fitted sockets.
1 The airco does not start.
Causes and Solutions:
1.1 No power is supplied.
(Check the electric connection).
2 The airco runs, but the compressor does not start.
Causes and Solutions:
2.1 Thermostat with too high temperature.
(Lower the thermostat temperature).
2.2 The ambient air is less than 18°C.
(No solution).
2.3 Switch is not set to "cold" position.
(Set it to cold).
3 The compressor stops running.
Causes and Solutions:
3.1 Low voltage.
(Less than 200V).
