MUST BE replaced by an authorised person in order to avoid a hazard, using genuine replacement parts available from Rinnai. Take care not to touch the power plugs with wet hands. Care should be taken not to touch the pipe work as it may be HOT! The pipes between the solar collectors and storage cylinder MUST BE copper, or alternative material pipes that may be supplied by Rinnai.

Gas booster located external to the storage cylinder. The following diagrams illustrates the Split Solar Hot Water System set up for both the Electric and Gas boost.
If the valve leaks continuously, try easing the valve gear for a few seconds. This may dislodge any foreign matter and alleviate the problem. If this does not alleviate the problem contact Rinnai. Operate the easing gear regularly to remove any lime deposits and to verify that it is not blocked.
Switch on the electric supply to the solar controller and pump. Solar water heating will now occur. Hot water is available immediately from the gas booster when hot water tap is opened, irrespective of solar heat gain.

This does not apply to Stainless Steel cylinders. Anodes suited to hard and soft water, are available from Rinnai. If the electric conduit, power supply cord or plug to the water heater is damaged, they must be replaced by an authorised person in order to avoid a hazard.
Before contacting Rinnai for service, follow the fault finding guide. If problems persist or this information doesn’t answer your questions, contact Rinnai on the phone number on the back of this manual.

SPECIFICATIONS FOR SYSTEMS GENERAL Split solar hot water systems are specified according to the grade of storage cylinder material, cylinder capacity, number of solar collectors and boost type and capacity. Boost capacity for gas boosted system depends on the gas booster model selected. Boost capacity for electrically boosted systems depends on the power rating of electric heating elements and whether one or two electric heating elements are fitted.

- Units will operate at lower pressures but the rated flow will not be achieved. - Gas boosters for Solar hot water applications must be set by Rinnai to deliver a minimum temperature of 70°C. Solar Gas boosters will be marked as Solar. Units not marked ‘Solar’ MUST NOT be used.
The solar storage cylinders have an ingress protection rating of IPX4 making them suitable for internal or external installation. Rinnai 'external' gas boosters are suitable for external installation only. Storage cylinders must be installed in freestanding mode on a level and stable base. For external installations, storage cylinders should be mounted on a concrete base at least 50mm thick or on well seasoned, evenly spread hardwood slats with a thickness of at least 25mm.
All hot water pipework should be insulated with sealed Polyethylene foamed or equivalent insulation to optimise performance and energy efficiency. Such insulation may also be mandatory under local regulations. Rinnai recommend insulation to achieve an R value of 0.6 K.m /W. With the exception of solar collector flow and return pipes, water pipe sizing should be performed in accordance with AS/NZS 3500.
Power MUST be turned OFF to the Controller before opening the controller box. WARNING • Power MUST be OFF when adjusting Dip Switches. Rinnai Australia - 19 - Solar Split Systems Operating / Installation Manual - Version 9 - 21/11/12...
An approved pressure limiting valve (supplied with some systems) is required if the maximum rated water supply pressure in Table 2 is exceeded. Rinnai Australia - 20 - Solar Split Systems Operating / Installation Manual - Version 9 - 21/11/12...
INSTALLATION OF SOLAR COLLECTORS REGULATIONS AND OCCUPTATIONAL HEALTH AND SAFETY (OH&S) Installation and commissioning must be performed by authorised persons.

Applicable publications and regulations may include: •...
For mounting options not shown in Figure 17, for example in areas where the cyclone frame can not be used, consult your nearest Rinnai Branch or Rinnai Representative. It is normal to mount the solar collectors down close to the gutter. Roof construction must be checked to ensure that the roof timbers are capable of supporting the additional load.
