evoUV units are splashproof but not waterproof. The unit can be positioned either
on a horizontal or vertical surface.
When installing vertically, position the unit with the drain plug at the bottom.
Your evoUV must not be submerged in water or placed in a position where water
may collect around the unit.
Fix your evoUV into position using the stainless steel brackets attached to the
evoUV. Screws and washers are not provided. On the evo30 and evo55 models
a third bracket is attached to the rear serial number plate. This bracket is angled
down during transit. Turn the bracket upright to install.
When fixing to the wall please leave a 1 metre gap at one end of the evoUV to
enable bulb / quartz sleeve removal and maintenance.
If installing the unit prior to or without a pond filter, we would recommend that the
use of a pre-filter is used on the water pump to prevent excess solids from being
pumped into the unit. The evoUV may be connected to the water flow on any
pumped line, this could be, for instance, a skimmer line or any other additional
pumped line. The two most common forms of set up are pump fed and gravity fed.
These are illustrated on the following pages.
It is possible that because of the positioning of your pipework, you may want to
install the evoUV upside down. Your evoUV can be positioned in this way, but it is
likely to cause an air lock. If this occurs the drain plug can then be used to release
the trapped air.
Positioning the evoUV this way will mean that the drain plug can not be used to
drain the unit, therefore extra care must be taken during maintenance and when
the bulb and quartz sleeve are being replaced to ensure the end caps and electrical
connections are kept dry.
