Correx Powered Anodes - andrews 32/143 Installation Manual, Operation And Service Manual

SECTION 3 INSTALLATION
CORREX FITTING AND OPERATING INSTRUCTIONS
POWERED
THE INTRODUCTION OF THIS KIT HAS THREE MAIN ADVANTAGES TO BE
ANODES
CONSIDERED
a) LOW MAINTENANCE COSTS (Correx is non sacrificial, therefore no anode
maintenance is needed).
b) LOW RUNNING COSTS – LESS THAN 35kWH PER YEAR.
c) BETTER PROTECTION PARTICULARLY IN AREAS OF LOW ELECTRICAL
CONDUCTIVITY.
Wiring external to the water heater must be installed in accordance with the I.E.E.
Regulations for the wiring of buildings and to any loca lregulations that may apply.
This kit is designed to run off 220/240V 1ph 50Hz permanent supply and the fuse
rating is 3Amp.
The method of connection to the mains electricity supply should facilitate complete
electrical isolation of the appliance preferably by use of an unswitched shuttered socket
outlet in conjunction with a fused three pin plug both complying with requirements of
BS1363/A.
Alternatively a fused double pole switch o rfused spur box serving only the heater may
be used.
The point of connection to the mains should be readily accessible and adjacent to the
appliance.
A. To install the kit
1. Drain down water heater.
2. Remove cold inlet hydrojet nipple and replace with 1 1 ⁄ nipple supplied in fittings pack.

3. Fit correx anodes into front hot and cold water connections using tees and bushes. If
top water
connections of heater are to be used (dependent on model type) cap off front
connections with blanking caps (see Figs.1 and 2 on page 21). Note: leave existing
magnesium anodes in position.
4. Fix potentiostat to heater casing, using retaining bracket. (See Fig.1)
5. Connect output leads onto anode connections. Cut leads to required length and use
two spade connectors provided. (See Fig.1)
6. Fit earth strap to 1 ⁄ BSP sq.tee optional hot outlet connection. Connect earth return at
1
2
this point. Cut lead to required length and use spade terminal provided (see Fig.1).
7. Connect potentiostat mains input cable to a permanent 240V electrical supply via an
unswitched spur outlet (fuse rating 3 Amps).
B. Test the installation
1. Refill the water heater and check for leaks.
2. Switch on electrical supply to correx powered anode.
3. The green control lamp on the potentiostat indicates that the installation is
functioning correctly.
4. The red control lamp on the potentiostat indicates a fault. Switch off electrical supply
before any repair work is carried out.
The installation is now complete.
