CONNECTION TO ELECTRICAL SUPPLY
Consult a qualified electrician.
Caution: Use in the area of the garden pond only if the installation complies
with the relevant wiring regulations.
Caution: Always disconnect all pond appliances from the mains electricity
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.
Important: This unit is designed to be permanently wired to the mains
supply using the three core 0.75mm
the unit. This unit must be permanently connected to the mains supply
inside a dry, weatherproof enclosure and through a double pole switched
fused spur with a minimum contact gap of 3mm. The fused spur must only
be fitted with a 3 amp fuse. For safety never use a larger rated fuse.
This unit is fitted with 5 metres of power cable. To prevent the unit
inadvertently being dropped into the pond, we strongly recommend that it
is securely positioned at least 2 metres from the edge of the pond. Any
flexible cabling used between the unit and the permanent wiring should
also be kept to a minimum length. We recommend a maximum length of
1.5 metres.
ROUTINE MAINTENANCE
The UV lamp inside the Pro Clear Ultima unit has a usable life of
approximately 8000 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.
Loosen the screws and remove the blue end covers from either end of the
unit. Carefully pull off the white plastic electrical lampholder. 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.

ASSEMBLY PROCESS
Slide the quartz sleeve into the unit. Ensure that you locate the two "O" rings
carefully on the ends of the quartz sleeve. Failure to do so will result in leaks
when the water is turned on. If you are carrying out the annual lamp change,
use new "O" rings. Hand tighten the compression fittings. Replace the lamp
or fit a new one. Relocate the white electrical end caps onto the pins of the
lamp and slide the rubber endcaps over the compression fittings. Reconnect
and turn on the water supply, carefully checking for any leaks before switching
on the electricity supply.
