.
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 on0151 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 Filling Procedure.
6.5.1 Turn on the Mains Water Supply to the Heat Bank Thermal Store, WHILE KEEPING the Isolating Valve [10] below the Solenoid Valve [10] closed.
6.5.2 Turn on the Electrical Supply to the controls. The Solenoid Valve [67] will be powered to allow water to pass.
6.5.3 SLOWLY open Isolating Valve [10] below the Solenoid Valve [10]. The unit should start to fill.
6.5.3.1 The radiator system is filled automatically with water from the Heat Bank Thermal Store.
6.5.4 Once the Heat Bank Thermal Store is full, bleed the entire system, including all radiators, to remove air.
6.6 Check that all air locks in the Primary System are cleared properly, and all Radiators bled.
7 COMMISSIONING.
7.1 Set the Room Thermostat to its maximum setting.
7.2 Set the Heat Bank Thermal Store Pump to speed 2.
7.3 Turn on the electrical supply.
7.4 Bleed all pumps as described.
7.5 Run through the operation of the system as follows:
7.5.1 Bleed the entire system to remove air.
7.5.2 The unit must be heated up to complete commissioning. This will require the electrical supplies to the immersion heaters to be turned on. Should the electrical heater supply to the unit be unavailable, check with the electricity suppliers for information about when the supply will be available.
7.5.3 Check that the water level in the Feed & Expansion Tank is at least 25mm below the overflow (once the unit has FULLY recovered). If necessary, adjust the position of the Ball Valve Float to obtain this.
7.5.4 Once the cylinder has recovered, check that hot water is available at all outlets.
7.5.5 Turn on the central heating by use of the Time Clock on the Wiring Centre [42].
7.5.5.1 Check that the central heating pump switches on, and that hot water is pumped to radiators.
7.5.5.2 Balance the radiator system as required, to ensure that heat reaches all radiators adequately.
7.5.5.3 Turn off the central heating, and set up the time clock to the house-holders preferences.
