IMPORTANT INFORMATION SAFETY WARNING • This appliance must be installed, commissioned and serviced by an authorised person in accordance with all applicable local rules and regulations. • Access covers of water heating system components will expose 240V wiring and must be removed by authorised persons only. • This water heating system is not intended to be operated, adjusted or tampered with by young children or infirm persons.
IMPORTANT INFORMATION Gas boosted models only • Do not touch the flue outlet or do not insert any objects into the flue outlet. • Keep flammable materials, spray cans, fuel containers, trees, shrubs and pool chemicals etc. well clear of the flue outlet. HOT! • Do not use the gas types other than those designated on the data plate. For example, do not use Propane/Butane gas mixtures on appliances marked Propane Gas. • Do not use Propane gas on appliances marked as Natural Gas and vice versa.
IMPORTANT INFORMATION OPERATION PRINCIPLE This system is designed to have the solar collectors on the roof and the storage cylinder installed at ground or floor level. Electric and Gas boosted models are available. The system comprises a hot water storage cylinder, solar panels, pump circulation system solar control unit and temperature sensors.
IMPORTANT INFORMATION Pressure and Temperature Relief (P&TR) Valve Twist cap until water flows from the drain line. This valve is located near the top of the water heater and is essential for safe operation. It is normal for the valve to release a small quantity of water through the drain line during heating. However, continuous leakage of water from the valve and its drain line may indicate a problem with the water heater. The valve may be either of the two illustrated.
IMPORTANT INFORMATION WATER TEMPERATURE The solar control unit and pump ensure water circulates between the solar collectors and storage cylinder until the water at the base of the cylinder reaches approximately 65°C. Under these conditions water at the hot outlet may exceed 85°C. During periods of low solar gain supplementary heating occurs to a minimum of 60°C as required. • To meet Australian regulatory requirements, supplementary heating temperature settings must be at least 60°C.
SAVE A SERVICE CALL Before calling Rinnai for service, perform the fault finding steps in the Table 1 below. If the problem persists, contact Rinnai. Service calls attending to any condition or fault that is not related to the Rinnai product and components may be chargeable.
SAVE A SERVICE CALL Problem Cause Remedy Insufficient or no hot Water continued Booster element Thermostat Settings Electric Boosted Systems: The end user can check the temperature of hot water delivered with a thermometer placed under the closest non tempered outlet (usually the kitchen sink). CAUTION: Take care to avoid scalding. This test should be done early in the morning after overnight electrical boosting before any hot water is used.
SPECIFICATIONS FOR SYSTEMS GENERAL Split solar hot water systems are specified according to the grade of storage cylinder material, cylinder capacity, number of solar panels 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.
SPECIFICATIONS FOR SYSTEMS The installer will need to set the flow rate to the value shown in Table 4 below. Table 4 - Optimum Flow Rate (Litres/min). Electric Boosted Gas Boosted No. of Collectors Zones 1, 2 & 3 Zone 4 1 0.50 0.50 2 1.00 0.65 3 1.25 1.00 1 0.50 0.50 2 1.25 1.25 3 2.10 2.10 Differential Temperature Controller The primary task of the differential temperature controller is to control the operation of the pump to optimize solar energy collection.
