5.6 If the Programmer is supplied loose, wire to the labelled connections in the Wiring Centre.
5.7 Wire the Immersion Heater to a suitable switched supply, fused rated to 16 amp.
5.8 Check the Immersion Heater Thermostat is set to 80°C.
5.9 The connection to the Mains Supply is made to terminal TB11 as standard. A 3 Amp fuse is fitted, with one spare fuse.
5.10 IMPORTANT: If the Mains Supply to the Wiring Centre is to be taken from the Boiler, please use the fused terminal block, TB11, for the Live, Neutral & Earth connections to the boiler - only the Switch Live and Pump Live terminals should be connected to the Boiler terminal block, TB3.
5.11 IMPORTANT: If the Boiler is used to switch the Primary Pump the Link LK1 should be cut. If boiler is NOT used to switch pump, link LK1 is NOT cut and the connection to terminal Lp is omitted.
6 FILLING.
6.1 IMPORTANT: SYSTEMS SHOULD BE FLUSHED AND PROTECTED IN ACCORDANCE WITH BS7593-1992. Please check Boiler and other Primary Equipment's Installation Instructions prior to filling.
6.2 It is important that SENTINEL X100 Inhibitor is used to protect the Heat Bank Thermal Store. 
Use 1 litre per 100 litres of stored water.
Label the unit as protected with the label provided.

Alternatively contact Fernox on 01799 550811
.
6.3 IMPORTANT: The Primary System should be fully flushed and an inhibitor, suitable for the purpose, used to protect both the primary and the Heat Bank Thermal Store systems. Betz Dearborn SENTINEL X300 should be used to flush the Primary System prior to filling new systems. Use SENTINEL X400 for existing systems. Please contact Betz Dearborn direct for method statements on 0151 424 5351, or alternatively contact Fernox on 01799 550811.
6.4 Everest Heat Bank Thermal Stores are fitted with a manual vent to the F&E Tank, fitted with a lockshield valve. This can be opened during initial filling to speed up filling. Once the unit has been filled the lockshield valve should be closed.
6.5 The Heat Bank Thermal Store is filled by opening the mains water supply to the Ball Valve.
6.6 To fill the Primary System, connect the Filling Loop provided to the Primary Filling Point, and open. Disconnect the filling loop after use.
6.7 The Pressure Relief Valve is fitted with a Pressure Gauge to aid filling.
6.8 Check that all air locks in the Primary System are cleared properly, and all Radiators bled.
6.9 IMPORTANT: Check that the Primary System is filled to a suitable pressure as per requirements for sealed systems.
6.10 The filling loop should be only be re-connected to feed the Ball Valve, if an overflow is fitted.
7 COMMISSIONING.
7.1 Remove the Programmer from the its wiring plate and ensure that the battery commissioning strip is removed. Replace the programmer and secure it properly.
7.2 Set the Room Thermostat to its maximum setting.
7.3 Set the Boiler Thermostat to maximum.
7.4 Ensure that the Cylinder Thermostat is strapped to the unit in good contact with the cylinder wall, and is set to 75°C.
7.5 Set the Primary Pump to Speed 3.
7.6 Set the Heat Bank Thermal Store Pump to speed 2.
7.7 Follow any specific commissioning instructions given in the Boiler Installation Instructions.
IMPORTANT: ONLY SUITABLY QUALIFIED INSTALLERS CAN COMMISSION A GAS BOILER.
7.8 Turn on the electrical supply.
7.9 Bleed all pumps as described.
7.10 Run through the operation of the system as follows:
7.10.1 Set the programmer to Hot Water ON.
7.10.2 The boiler should fire, and the primary pump turn on. Within a short time (3 minutes) the flow from the boiler should feel hot to the touch. Check that the pipework to the primary coil is also hot. The flow to the central heating should not be hot at this stage.
7.10.3 Set the Programmer to Heating ON. The flow to the heating circuit should now get hot.
