FLOW RATES
Both of our Pro Clear Advantage units have a maximum flow rate as listed
below. Please note that for optimum performance we recommend that you pass
the entire volume of your pond through the UV 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.
Unit Maximum Flow Rate
Pro Clear Advantage UV30 3,000 Imp. gallons/13,500 litres per hour.
Pro Clear Advantage UV55 4,000 Imp. gallons/18,000 litres per hour.
SYSTEM PRESSURE
The unit has been designed for use with all types of domestic garden pump
(working pressure not to exceed 0.7 bar). Advice should be sought from your
dealer if the unit is to be subjected to abnormal conditions.
CONNECTION TO THE ELECTRICITY SUPPLY
If in doubt consult a qualified electrician.
Caution: Use in the area of the garden pond only
if the installation complies with the relevant wiring
regulations. Please consult a qualified electrician.
Caution: Always disconnect all pond appliances
from the mains supply before putting your hands
into the water.
Caution: Power must be supplied through a
Residual Current Device (RCD) with a rated
residual operating current not exceeding 30mA.
All electrical installations and wiring must be
adequately protected to prevent any damage.
Mains electrical cable is not supplied with the unit. This unit must be connected
to permanent wiring. A switch with 3mm contact separation must be provided in
the fixed wiring to provide disconnection from the electricity supply.
Remove the lid by unscrewing the four screws on either side of the Pro Clear
Advantage unit. Feed one end of the cable through the cable clamp and connect
to the junction block as shown above. Before replacing the cover, feed the
cable out of the unit via the cable channel in the main body. Replace the lid and
fasten the screws.
INTERNAL FUSE REPLACEMENT
Always isolate the unit from the mains supply before undertaking any
maintenance. All units use a 3 amp fuse. Never use a larger rated fuse.
ROUTINE MAINTENANCE
The UV lamp inside the Pro Clear Advantage unit has a usable life of
approximately 7000 hours. As green water is only usually a problem during
spring and summer, the lamp only needs to be replaced once a year in the spring
(see below).
As already mentioned it is essential that the unit is protected from frost during
the winter months, or disconnected from water and electricity supplies and
stored indoors. During the spring and summer season, the quartz sleeve, which
separates the UV lamp from the water passing through the unit, will need to be
cleaned two or three times (see below). This is essential, as dirt building up on
the quartz sleeve will inhibit the penetration of the ultraviolet light into the
water and affect the efficient working of the unit.
IMPORTANT
The black plastic body and any hosetails supplied with this unit are
manufactured from polymers that have been specifically stabilised, to protect
them from the effects of UVC light wavelength emitted from the lamp. Despite
this UV protection the plastic body and hosetails will be eroded by the UVC
and the water flow. As a matter of course they should be inspected whenever a
lamp change is carried out, to ensure that they are not showing excessive wear
and tear. Low cost replacements are available from your local aquatic supplier.
LAMP REPLACEMENT AND QUARTZ CLEANING
Always isolate the unit from the electricity and water supplies before carrying
out any maintenance on the unit.
Peel back the rubber end caps from either end of the unit and carefully pull off
the white plastic electrical end caps. Carefully slide the lamp out of the unit.
Next, unscrew the two compression fittings located at either end of the main
body (see diagram) and slide off the two “O” rings from either end of the quartz
sleeve. Carefuly slide out the quartz sleeve. Clean the sleeve and polish with a
soft cloth or paper towel. If you live in a hard water area there may be some
limescale on the quartz sleeve; this can be easily removed by soaking the sleeve
in a proprietary plastic kettle descaling solution. Failure to remove the
limescale will limit the effectiveness of the UV lamp.
