PUMP
The root washer stands in the centre of the tank with the pump underneath. The
pump stands in the water and draws it through its base filter, up through the body
and out at the top. It is designed so that is does not require any priming but it
must not be allowed to run dry for many minutes. For users who have 220/240v
supply at 50/60Hz there is a float switch which cuts the pump supply when the
water level gets dangerously low.
ELECTRICAL SAFETY
The optional root washer recirculation pump, type RWP, should only be installed
by qualified electricians in accord with local Health and Safety Regulations.
Cabling should be protected against damage, with the use of protective cable
trunking and by siting it out of harms way. Do not let it lie on a floor which may
become wet or damaged as a result of root washing or other activities. It is good
practice to run the cable overhead. The mains power supply to the pump should
be fused to a 13A rating.
INSTALLATION
Stand the pump on its end, on the floor, in the centre of the tank.
Cut a 2 m length from the 20m hose.
Connect the pump to the hose with the largest hose connector.
Position the pump bypass hose so that it can drain freely bank into the tank
without restriction.
Arrange the float switch so that it does not interfere with the table legs and adjust
it so that it cuts the pump when the level reaches 100mm.
Fill the tank to 75mm from the top.
(There is a hose adapter at the top of the tank
which can be used to fill the tank as well as acting as an overflow) .
Arrange the pump cable safely and with consideration to the electrical safety
hazard warnings given on page 2.
Do not operate the pump until the electrical safety considerations have been fully
complied with.
