Instruction manual
FLOW RATES
Your evoUV will withstand operating pressures of 20 metres head. This means that
evoUVs are able to operate with most of the circulating pumps commonly used.
Please note: For optimum performance we recommend that you pass the entire
volume of your pond through the evoUV unit approximately once every two hours.
Please also note that we recommend a minimum flow rate equivalent to passing
the entire pond volume through the unit once every three hours.
It is important to note that there are factors that affect how you select the right size
of evoUV for your pond.
Your evoUV will keep your pond clear of green water up to its maximum capacity as
stated on the box for the evo30 and evo55. The evo110 is an effective unit and has
multiple uses. It can be used on large ponds, retail installations, aquaculture and
other commercial aquaria installations. Please see your local Evolution Aqua dealer
for details.
