3.0 - INSTALLATION
a. Install the pump away from heat sources, in a dry place and at a maximum ambient temperature of 40°C. The
m i n i m u m o p e r a t i n g t e m p e r a t u r e o f t h e p u m p d e p e n d s o n t h e l i q u i d t o b e d o s e d , a s t h e l i q u i d
m u s t r e m a i n i n a f l u i d s t a t e . If the pump has been stored at an ambient temperature of less than 0°C, make
sure that any water present in the pump body is in a liquid state before starting up the pump.
b. Carefully observe the regulations in force for the electrical plant in the country where the pump is installed
(Fig. 4).
If the power cable has no plug, the equipment must be connected to the power supply using an omnipolar
switch with a minimum distance of mm. 3 between the contacts. Before accessing the power connection
devices, all power circuits must be interrupted.
c Locate the pump in position as shown in fig. 5 taking into account that it can be located over or under the liquid
level within a maximum difference of 2 meters. The injection point must always be located higher than the liquid being
injected. Do not install the pump directly on the tank as some additives produce vapour which may damage
the equipment. For correct installation see fig.12. If the plant being treated operates at atmospheric
pressure (free discharge additive) and the additive tank must be placed higher than the injection point (Fig. 6),
check periodically that the injection valve is operating correctly, as excessive wear could cause additive injection
by liquid loss (even when the plant is not operating). If the problem persists, insert a correctly calibrated
counter pressure valve C between the dosing pump and the injection point (Fig. 6). For liquids that give off
aggressive exhalations, do no t install the pump o ver the tank u nless the tan k is he rm etically sea led .
d. The outlet fitting must always be on the upper part of the pump, from which the piping to the plant being treated will be
connected. Consequently, the suction fitting will always be on the lower part of the pump, where the piping and filter to the
liquid container will be mounted.
e. Slide out the two red protection capsules from the fittings; insert the piping all the way onto the conical
attachments and lock them using the fixing rings (Fig. 7).
Pay attention to the Yellow/Green
Earth protection conductor
It must be connected to the power
supply earth protection conductor.
