INSTALLATION AND CONNECTION OF THE FAN TO THE MAINS

The fan (fig.1) consists of the body 1 with fixed electric motor and impeller 4. Terminal box

cover 3, pipes 5 (pipe diameter corresponds to the diameter of the air duct); quick-

detachable clamps 6.

Air moving direction of the air should coincide with the direction of the arrow on the fan

body.

For the installation of the fan it is necessary to carry out following operations: 1) Remove

two clamps 6 and to take out the body 1. 2) Drill holes for dowels, according to the

coupling sizes and fix the pipes by means of 4 screws. 3) Insert the body 1 and fix it with

clamps 6. 4) Connect air ducts of the relevant diameter.

Connection of the fan to the single-phase circuit should be carried out through the switch

built-in into the stationary wiring. The gap between contacts of switch at all poles should

be not less than 3 mm.

Connection layouts of the fan to the stationary wiring are shown on figs. (2-3). In case of

one-speed operation at one speed, it is necessary to connect the wire L of the mains to

one of the terminals, corresponding to the s elected rotation speed:

maximum speed

minimum speed

Speed of the fan is switched using external switch S1. Fan with timer T (fig 3) ensures

automatic turning off the fan after certain time from 2 to 30 minutes, set up by the timer.

Turn-off delay time is adjusted, using the handle of potentiometer, rotating it clockwise to

increase the delay time and anticlockwise to decrease it.

To connect the fan to the mains, it is necessary to:

-remove the cover from terminal box,

-extend electric wires through the gasket ring, located on the terminal box,

-remove insulation from the ends of wires by 5-6mm, insert them into appropriate

terminals until insulation is rested against the metal part of the terminals, and fix them

with screws,

-place back the terminal box cover.

ATTENTION!

Launching the fan, equipped with timer, occurs within approximately 5 s after turning on

external switch S2.
