4.4 Filtration and Water Quality
The
Bianco Rainsaver MK4E is designed to operate on clean rainwater and clean mains water
supply, and as such, the rainwater tank should be fitted with an inlet strainer, preferably shaded type
to reduce algae, and a suitable first flush device.
White International strongly recommends the use of a strainer or filter upstream with easy access for
period cleaning from both the rainwater and mains inlet connections of the
Bianco Rainsaver MK4E .
Additional water filters may be required. Also check the water tank and first flush diverter as per
manufacturers’ instructions regarding periodic servicing that is required.
Filters need to be checked regularly as reduced flow caused by blocked filters can damage pumping
equipment.
4.5 Plumbing
Plumbing connections should be carried out by a licensed plumber.
Use of flexible pipe connections and isolation vales is recommended to assist in alignment and
servicing and to reduce any transmitted noise.
Use a standard
¾” compression
x F.I. union or Compression x F.I. elbow fitting to connect between
¾” copper tubing and ¾” BSPT threaded
pipe fitting
at the “MAINS” inlet, “PUMP
INLET
”
(if unit is
wall mounted)
, and “HOUSE” outlets.
Use standard ¾” BSP female threaded fittings to connect to ¾” BSPT threaded
pipe fitting when
connecting other types of piping.
DO
NOT
REMOVE THE UNION NUT AND ¾” BSPT PIPE FITTING AND ATTEM
PT TO CONNECT
PIPE WORK DIRECTLY TO THE BODY OF THE UNIT!
DO
NOT ATTEMPT TO CONNECT COPPER OR PLASTIC PIPE, USING COPPER OR NYLON
OLIVES, A
ND COMPRESSION NUT DIRECTLY TO THE ¾” BSPT PIPE FITTING!
Always use the spanner provided, or correct open ended spanner, when tightening fittings.
All pipe-work and outlet fittings from the RainsaverMK4E must be labelled to AS3500.
The
RainsaverMK4E control incorporates a dual check valve to prevent cross connection between
mains and rainwater. Connection to an underground rain water tank, or local water supply authorities,
may require additional, or higher safety level, back flow prevention, and your licensed plumber can
advise you on this.
The incorporation of an additional
“
Tee
”
fitting between the tank water pressure pump supply, and the
RainsaverMK4E lower
“PUMP INLET”
, will allow the householder to use collected rainwater, but
NOT mains water supply, to irrigate gardens and lawns, or wash cars.
