4.2 Installation
 Place the Enpres in a suitable place:
o
place the Enpres on a stable foundation;
o
make sure the Enpres is placed level;
o
make sure the Enpres can’t vibrate out of its place;

if necessary, use vibration dampers and holders;
o
make sure there is sufficient free space around the Enpres;
o
make sure the Enpres is protected to rain, frost and heat;
o
when using the petrol powered Enpres; make sure there is sufficient ventilation.
 Connect the suction line (connection 12):
o
use flexible spiral lines for the connections;

this prevents lines from rupturing of breaking due to vibrations;
o
use a sufficiently large filter;

maximum filtration degree 200 μm;

this prevents dirt as well as foreign object from entering the pump or suction line;
o
make sure the suction line can’t empty (not even partially) while the pump is not running;

this prevents air from entering the suction line;

when the pump runs without fluid, there is a substantial risk on irreparable
damage to the pump.
 Connect the press line (connection 21):
o
use flexible spiral lines for the connections;

this prevents lines from rupturing or breaking due to vibrations;
o
install a non-adjustable overpressure valve.
 Connect the overflow line (connection 20):
o
do not connect the overflow to the suction line;

this seems practical, but can influence the functioning of the pump negatively.
When the overflow would be connected to the suction, the temperature of the
fluid would rise quickly above the maximum of 40°C and cause a dramatic
reduced lifetime or irreparable damage to the pump;
o
use flexible spiral lines;

this prevents lines from rupturing or breaking due to vibrations.
Whit an electrical powered Enpres:
 connect the earth connection;
o
use the instruction in the annexes;
 connect the electrical power;
o
use the instructions in the annexes;
 connect the electronic pressure switch (optional);
o
use the instructions in the annexes;
 use a maximum current protection with current setting to prevent damage to the electromotor;
o
make sure the maximum current is set to the right value;

see the annex “Electrical connection of the three position switch”;
o
if a protection is already incorporated in the logic controls/software no additional
protection is needed;
 place a main switch;
o
this switch must physically disconnect the entire Enpres before reparations and such;

use a short-circuit protection where needed;
 place a emergency stop where needed.
