Installer checklist

Please remember to carry out the following checks after installation. This will achieve complete customer satis-

faction, and avoid unnecessary service calls. A charge will be made for a service visit where the fault is not due to

a manufacturing defect.

– Has a correct by-pass been fitted and adjusted?

– Has the system and boiler been flushed?

– Is the system and boiler full of water, and the correct pressure showing on the pressure gauge?

– Is the Auto Air Vent open?

–Has the pump been rotated manually?

– Is the gas supply working pressure correct?

– Is the boiler wired correctly? (See installation manual).

–Has the D.H.W. flow rate been set to the customer requirements?

– Has the customer been fully advised on the correct use of the boiler, system and controls?

–Has the Aqua Guard Filter been cleaned (see 4.5.2)?

– Has the Benchmark Checklist in the use and maintenance section of this manual, been completed ?
