Sicce CO2 LIFE Instrucciones página 9

•Power must be supplied by a differential protection device (RCD), with rated residual current
beneath 30mA.
INSTALLATION AND USE
ATTENTION: disconnect all electric appliances before putting hands in water. Before plugging
the device in, make sure it is damage free in all of its parts, especially the cable and plug. Take
the product out of the box and undo the cable.
1) Insert suction cups in their seats and rotate until certain they are properly fixed (fig. 2).
2) Clean the glass and place the pump vertically, with knob facing upwards (fig. 3), applying pres-
sure so suction cups adhere. Make sure the pump is completely immersed in water.
ATTENTION: to avoid vibration and resonances, DO NOT position the remaining sides of the
device to the bottom or sides of the tank.
3) Turn the knob, placed on top of the unit, clockwise to increase CO2 emission, counter clock-
wise to decrease it (fig. 4)
4) Plug the product to the power socket.
IMPORTANT: ADVISE FOR USE
• Emitting Co2 in water will cause an unavoidable decrease of the pH: it is advisable to monitor
this value constantly.
• During first use, the carbon cartridge is very sensative. Set it on the MINIMUM setting for at
least 24 hours, then measure CO2 concentration (see previous paragraph). If necessary, go up
a notch (not more!) every 24 hours, until optimal levels are reached and maintained.
• During electrolysis, the output, from the frontal grills, of CO2 mixed with water is invisible. The
speed of the emission depends on the hardness and conductivity of water. CO2 should not
be confused with bubbles of hydrogen (produced by electrolysis) that go towards the surface.
Although the output of CO2 invisible to the human eye, this is the correct operation of the unit!
IMPORTANT: remember that the abrupt interaction with the chemistry of water is a mistake that
would compromise the delicate balance of the aquarium's environment.
• It's possible to deactivate the pump during the night (when the absence of light hampers pho-
tosynthesis), by simply connecting it to a timer (no need of complicated solenoids). Test to make
sure the Ph level doesn't increase inappropriately : if this happens, the pump MUST keep work-
ing.
• The cartridge's life can vary notably, depending on water hardness: a high concentration of
minerals ("hard" water) helps conduciveness (measured in Micro-Siemens cm2 µS/cm2), con-
suming carbon more quickly
• It's advisable to partially change water every month (20-25% of the tank's volume), using re-
verse osmosis or demineralised water, in order to keep the hardness of water stable;
• It is necessary to clean deposits from the tank's lamps or light shields regularly and to substitute
them once a year: low quality/ intensity light does not permit a correct photosynthesis in plants.
• Excessive movement on the water surface reduces CO2 molecules.
MAINTENANCE
ATTENTION: disconnect all electrical appliances from power supply before putting hands in
water.
1) Grasp the pump body and take it out of support (that remains attached to the glass); do not
tug on cable to do this operation
2) Remove the transparent mixing cover, lifting it from pump body (fig: 5)
3) Remove the cartridge's regulator and pre-filter;
