Positioning the Unit
CAUTION: To prevent this unit falling into water, do not install above
or alongside your pool.
The H.R.UV-C unit is weatherproof but not waterproof; it must be installed
in a dry weatherproof enclosure. The unit must be mounted on a flat
vertical surface horizontally or vertically. It must not be submerged in
water or placed in a position where water may collect around the unit.
To prevent the unit inadvertently being dropped into the pool, the unit
must be installed at least 3.5 metres from the edge of the pool.
The unit must always be plumbed into the water system after the filter as
shown in fig 3. to prevent dirt and debris being pumped into the unit.
