IMPORTANT: PLEASE READ ALL THESE INSTRUCTIONS BEFORE COMMENCING INSTALLATION THE INFORMATION CONTAINED IN THESE INSTRUCTIONS DETAILS HOW TO CONNECT THE PREMIER PLUS SOLAR CYLINDER TO A SOLAR PRIMARY CIRCUIT. OTHER CONTROLS WILL BE NECESSARY TO PROVIDE CONTROL OVER THE SOLAR PRIMARY CIRCUIT, REFER TO THE INSTRUCTIONS SUPPLIED WITH THE SOLAR CONTROLS AND ANCILLARY EQUIPMENT FOR DETAILS OF HOW TO INTEGRATE THEM WITH THE PREMIER PLUS SOLAR CYLINDER.
1.0 INTRODUCTION The Premier Plus Solar is a purpose designed unvented solar water heater. The unit has a stainless steel inner vessel which ensures an excellent standard of corrosion resistance. The outer casing is a combination of resilient ther- moplastic mouldings and corrosion proofed steel (Plastisol) sheet. All Premiers are insulated with CFC/HCFC free polyurethane foam to meet the latest European heat loss requirements (see Table 3).
3.0 INSTALLATION – GENERAL 3.1 PIPE FITTINGS All pipe fittings are made via 22mm compression fittings directly to the unit. The fittings are threaded 3/4”BSP male parallel should threaded pipe connections be required. 3.2 COLD FEED A 22mm cold water supply is recommended however, if a 15mm (1/2”) supply exists which provides sufficient flow this may be used (although more flow noise may be experienced).

INSTALLATION - DISCHARGE It is a requirement of Building Regulation G3 that any discharge from an unvented system is conveyed to where it is visible, but will not cause danger to persons in or about the building. The tundish and discharge pipes should be fitted in accordance with the requirements and guidance notes of Building Regulation G3.

7.0 COMMISSIONING 7.1 FILLING THE UNIT WITH WATER • Check Expansion Vessel pre-charge pressure. The vessel is supplied pre-charged to 3.5 bar to match the con- trol pressure of the Pressure Reducing Valve. The pre-charge pressure is checked using a car tyre gauge by unscrewing the plastic cap opposite the water connection.
8.0 MAINTENANCE 8.1 MAINTENANCE REQUIREMENTS Unvented hot water systems have a continuing maintenance requirement in order to ensure safe working and optimum performance. It is essential that the relief valve(s) are periodically inspected and manually opened to en- sure no blockage has occurred in the valves or discharge pipework. Similarly cleaning of the strainer element and replacement of the air in the expansion vessel will help to prevent possible operational faults.

When water flows from the hot tap allow to flow for a short while to purge air and flush through any disturbed particles. Close hot tap and then open successive hot taps in system to purge any air. When completely full and purged check system for leaks. The heating source (immersion heater(s), boiler or solar primary circuit) can then be switched on.
9.0 USER INSTRUCTIONS 10.1 WARNINGS IF WATER ISSUES FROM THE TEMPERATURE/PRESSURE RELIEF VALVE ON THE SANTON PREMIER PLUS SOLAR SWITCH OFF ELECTRICAL SUPPLY TO THE IMMERSION HEATER(S) (DIRECT UNITS),SHUT DOWN THE BOILER (INDIRECT UNITS) AND SHUT DOWN THE SOLAR PRIMARY CIRCUIT. DO NOT TURN OFF ANY WATER SUPPLY. CONTACT A COMPETENT INSTALLER FOR UNVENTED WATER HEATERS TO CHECK THE SYSTEM.
10.0 FAULT FINDING & SERVICING IMPORTANT • After servicing, complete the relevant service interval record section of the Benchmark Checklist located on page 24 and 25 of this document. • Servicing should only be carried out by competent persons in the installation and maintenance of unvented water heating systems.
