Description of the Product 4

5.2.2 Electrical Supply

1. External wiring must be correctly earthed, polarised and in

accordance with relevant regulations/rules. In GB this is the

current I.E.E. Wiring Regulations. In IE reference should be

made to the current edition of ETCI rules.

2. The mains supply is 230V ~ 50Hz fused at 3A.

The method of connection to the electricity supply must

facilitate complete electrical isolation of the appliance.

Connection may be via a fused double-pole isolator

with a contact separation of at least 3mm in all poles

and servicing the boiler and system controls only.

Isolation of the boiler can be checked at the electrical

test point.

5.2.3 Hard Water Areas

1. If the area of the installation is recognised as a HARD

WATER AREA then this must be taken into account when filling

the system.

5.2.4 Bypass

1. An automatic bypass must be fitted on the system for

protection of the boiler and pump.

5.2.5 System Control

1. The system must be fitted with thermostats and TRVs to

comply with Part L of the Building Regulations.

5.2.6 Treatment of Water Circulating Systems

1. All recirculatory water systems will be subject to corrosion

unless they are flushed and an appropriate water treatment is

applied. To prevent this, follow the guidelines given in BS 7593

“Treatment of Water in Domestic Hot Water Central Heating

Systems” and the treatment manufacturers instructions.

2. Treatment must involve the use of a proprietary cleanser,

such as Sentinel X300 or X400, or Fernox F3 and an inhibitor

such as Sentinel X100 or Fernox MB-1.

3. Full instructions are supplied with the cleansing products, for

further information contact Sentinel (0800 389 4670) or Fernox

(0870 870 0362).

Failure to flush and add inhibitor to the system will

invalidate the appliance warranty.

4. It is important to check the inhibitor concentration after

installation, system modification and at every service in

accordance with the inhibitor manufacturer’s instructions. (Test

kits are available from inhibitor stockists.)

5. Complete the label supplied with the inhibitor and attach to

the inside of the boiler case. Detail of system treatment should

be added for future reference.

6. For information or advice regarding any of the above contact
