ELECTRICAL INSTALLATION

Electrical connection must be carried out by qualified person. Connection to current is shown on fig.
4.1, page 13. The electrical connection of pump to the current (1~230V, 50 Hz) must be carried out
with suitable connecting cable (equivalent to connecting cable 3G 1mm2, H05RR-F).
Means for disconnection must be incorporated in the fixed wiring in accordance with the wiring
rules.
The supply cord shall be connected so that the supply cord cannot come into contact with parts of
enclosure due to high temperature of the enclosure.
If the insulation of the fixed wiring supplying an appliance for permanent connection to the supply
mains can come into contact with parts having temperature rise exceeding 50 K during test of clause
11, the instructions shall state that fixed wiring insulation must be protected, for example, by
insulating sleeving having an appropriate temperature rating.
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by person responsible for their safety!
Children should be supervised to ensure that they do not play with the
appliance!

SETUP AND OPERATION

Pump settings can be changed with a button on electric box cover. Pumps enables choice between
three different preset curves with proportional pressure and three curves with constant power.
Switching between the levels is done by consecutively pressing the settings button. The button lights
up with the color that indicates the selected level. Blue indicates the lowest power, and yellow the
highest. The sequence is blue-green-yellow, then once again blue. The regulated performance can be
achieved by pressing the settings button for some time (>5 s) on the settings button. Shortly pressing
the settings button will return the pump back to the previously selected level. If the pump is
operating in the regulated area, the button blinks indicating that the duration of the blink shortens
with the decrease of the flow. When unregulated performance is selected, the button shines
continuously.
WHEN THE BUTTON PULSATES, THE PUMP OPERATES IN REGULATED MODE. FOR THE LADDOMAT
SYSTEMS, THE PUMP SHOULD ALWAYS RUN ON CONSTANT SPEED = CONSTANT LIGHT! (Fig.2, page7)
Hydraulic response in the regulated area is proportionate to flow. The set peaks for single chosen
level (see table) with inclination angle of 50%.
