FAN TYPE DVP

SUMMARY OF ASSEMBLY AND MAINTENANCE

1 Conditions and guarantees

of function

The user must respect the

conditions of use for which the

ventilator was supplied

(temperature, maximum speed

and atmosphere).

2 Transport – handling

and stocking

 Upon delivery, check the

number and condition of

the parts. In the case of

missing or damaged parts,

send all details to the

haulage contractor by

registered post within two

days. Also, give notice to

the supplier.

 Manipulate the ventilator

with precaution. To lift by

ring bolt when the ring

bolt are planned for this

use, otherwise use one

strap in belting the body.

Avoid impacts which may

damage the parts or

compromise the

equilibrium of the turbine.

If the ventilator undergoes even

a slight distortion repairs will

be necessary and the apparatus

will have to be re-equilibrated.

 Store the ventilator inside

(preferably in its original

wrapping) to shelter from

rain, dust and other

impacts. If it is to be stored

for a long period, run the

rotor motor for a fraction

of the tour every fifteen

days.

3 PRECAUTIONARY

MEASURES

3.1 Before installation

It is always preferable to check

the points below before

installation rather than after, to

avoid difficulty in assembling

and therefore loss of time.

 Be sure that the material is

well suited to the intended

use (diameter, number of

blades and speed, above all

in the case of multiple

deliveries or the recovery

of material left for another

use.

 Be sure that the electric

characteristics of the motor

are compatible with the

tension of supply and the

start mode expected

(above all in the case of

multiple deliveries or the

recovery of a material left

for another use).

 Check that the resistance

of the insulation of the

wind up motor. This must

not be less than 1000 per

volt of the tension used

with a minimum of 4 to

500.000, if this value is not

attained, dry the motor

(openings clear) in a local

well heated, if necessary

by electric heating or a

steam-room after

dismantling. Often it will

be sufficient to leave the

motor to empty with

ventilation closed for a

few hours.

 Check manually that the

turbine turns freely and

without knocks.

 Check that the turbine

turns in the direction of the

arrows placed on the

collar/hoop/sleeve, the

direction of the circulation

of air is this way.

3.2 Once installed

The ventilators fan type

DVP are normally

enclosed in a network of

casing or placed at the end

of the network. They are

assembled at the casing of

the ventilation either by

straps or by a flexible

connection.

The casing must not in any

case be supported by the

ventilator; this could exert

constraints resulting in

inadvisable distortions of

the body. It must be

directly supported by the

collars and the appropriate

supports.

If possible insert a flexible

connection between the

ventilators and casing.

When the ventilator is

placed on a chair or a

metallic frame, it is

recommended to insert

elastic studs between the

ventilator and the frame.

3.3 Electrical Connection

Use a safety device to protect

the motor against overloading

or the working of the mono-

phase (in the case of the tri-

phase supply). Consult the

diagram placed inside the box

at the boundary / terminal and following that, the tension of the network, to adopt the mode of coupling and the corresponding connections. Use the cables of sufficient section where the exterior diameter corresponds with the dimensions of the packing box. It is obligatory to put the motor on the ground. In the case of the start star triangle, conform to the Connection instructions supplied with the trunk/chest/ casket. Never touch the internal motor connections. 3.

CONDITIONS OF GUARANTEE Upon receipt of the material Check that all parts have withstood transportation and are in a satisfactory condition. In the case of identified damage, do all reservations with the haulage contractor by registered letter within two days. If these instructions are not adhered to, the products have travelled at the customer’s risk. In the course of handling Treat the ventilator with precaution. Avoid shocks which risk damage to the parts and their surfaces.
