500 SERIES FWD
WATER SUPPLY CONNECTION
A cold water supply with a minimum head of 4m is required on the 525 and 526 Disposers.
This is connected to the units at the solenoid valve using a 15mm compression joint,
supplied with the machine. A stopcock should be fitted to the water supply. The 523
disposer draws its water supply from the sink tap.
The 500 series machine is to be fed by a cistern tank not mains water supply.
ELECTRICAL CONNECTION
All electrical work must be carried out by a qualified electrician and in accordance with
the IEE Codes of Practice. Examine the rating plate attached to the motor to ensure that
the characteristics shown are correct for the supply available. The cables fitted to the
controller are the minimum required for individual connection to the mains supply. Site
conditions may vary with additional length of cable run, encapsulation in trunking, bunched
with other cables etc. Should this apply, the electrician must alter the cable accordingly.
(SINGLE PHASE MACHINES ONLY) The 500 Series Disposers must be connected to the
mains supply using the 32A isolator box, 30mA RCD and mains plug and cable all provided
with the machine. Please refer to PAGE 8 for full wiring instructions.
The RCD (Residual Current Device) is a safety device, which automatically switches off the
supply if an earth fault develops.
IMPORTANT! Please note that the RCD contained within the isolator box MUST be tested
on completion of the installation and then quarterly for the lifetime of the machine.
To test the RCD, proceed as follows:
Press the button marked “T”. The device should switch off the supply and should then be
switched on to restore the supply. If the device does not switch off the supply when the
button is pressed, seek expert advice.
WARNING: This machine must be earthed
All machines are supplied with a starter with forward, reverse and stop buttons. Where
automatic water control is supplied, the starter also controls the water flow. This unit
must be connected to the mains supply using the starter provided. Omission of the starter
eliminates overload protection for the motor and will invalidate the guarantee.
