1. 1 7 Siting the Heat Pump inside a garage or roof attic The Heat Pump can be sited inside a garage or roof attic space but consideration needs to be given to the large volume of air flowing from the air outlet If the space is too restrictive and not well vented the Heat Pump performance will be impaired firstly by the room pressure retarding the rate of air flow and secondly by the air temperature in the room falling as the Heat Pump expels cold air causing lower operating performance The Heat Pump will usually pick up a performance boost from the warm air ring up into the attic space from winter space heating or in summer from the sun s radiation heating the roof which conducts through to the attic air inside The rule is that the Heat Pump needs the internal space to be well vented and preferably the Heat Pump located up high so that the displaced warmer room air will rise up to be received by the Heat Pump air inlet As a guide the heat pump will improve its performance by around 20 for each 10 degree C rise in the air temperature Do not site the heat pump with the air outlet facing into a prevailing wind This will reduce performance For Service Technicians 7 3 6 13 Siddons Solarstream Pty Ltd 2 Heat Pump 2 1 Heat Pump Parts The parts box contains the following components e 1x Installation and Warranty manual e 4x adjustable feet with tightening nuts e 4x rubber feet for vibration absorption note addition2. major variations in electricity supply e Subject to any laws to the contrary there are claims for damage to walls foundations gardens etc and or any other consequential loss or inconvenience either directly or indirectly relating to the Solarstream or its operation e There is damage or breakage to property is not covered by this warranty which should be added separately to your general household insurance policy e There is extreme temperature above 45 C or below 5 C or excessively corrosive atmosphere 7 1 Heavily Mineralised Water Where a Solarstream is connected to a water supply from unfiltered or highly mineralised water sources such as a spring dam bore river or other natural ground sources we require that the water be tested Where water stored in the Water Tank exceeds the following characteristics an issue with corrosion may occur and void the water tank warranty WARRANTY EXCLUSIONS HEAVILY MINERALISED WATER Your warranty may become void where your Solarstream is connected to heavily mineralised water supply sources such as a spring dam bore and river or where your water quality exceeds these criteria e Total dissolved solids 600 mg litre or parts per million e Total hardness 200 mg litre or parts per million e Chloride 300 mg litre or parts per million e Sodium 150 mg litre or parts per million e Calcium 20 mg litre or parts per million e Magnesium 10 mg litre or parts per million e ron 1 mg litre e

We recommend brushing or hosing down the fins periodically once every 6 months A build up of grass or other material may prevent good air flow across the fins We also recommend that you release the pressure and temperature relief valve once every twelve months To do this simply gently raise and then lower the valve lever positioned at the top of the tank near the hot water outlet What do do if my Siddons Solarstream has a problem Firstly review our troubleshooting section of our website If still unresolved contact the Dealer you purchased your unit from lf you are unable to reach your dealer for any reason contact Siddons Solarstream Please make sure you have noted your serial number for warranty verification purposes Do need to register my warranty For efficient processing of warranty claims should they arise please register your Siddons Solarstream at www siddonssolarstream com For Service Technicians 28 3 6 13 Siddons Solarstream Pty Ltd Warranty WARRANTY The following warranty benefits in regard to your Solarstream are in addition to all other rights and remedies that you have under the Trade Practices Act and similar States and Territory laws This warranty applies from the date of purchase subject to following conditions otherwise the warranty may be voided WARRANTY COVER PERIOD e 5 years warranty on the storage tank e 4 years warranty on the heat pump compressor e 2 years warranty on oth

6. idea to quickly depress the Schrader valve to check that it has gas pressure You can recognise moisture in the lines if you have good head pressure but low temperature on the large discharge gas line running to the tank probably around 70 deg C instead of around 90 deg C The solution is to remove the gas charge completely evacuate the system then put a new pure gas charge back into the refrigeration circuit 4 2 Flooding the compressor lf the Solarstream water heater system is overcharged with gas the evaporator Heat Pump may experience difficulty in completely evaporating the gas prior to entering the compressor This will result in liquid gas flooding into the compressor causing lower discharge temperatures at higher pressure To detect this you may find the high pressure gas up around 2 700 kPa at 15 degrees ambient air whilst the temperature of the high pressure gas line is only around 75 degrees C whereas it should be up around 90 degrees C The remedy is to discharge some gas to bring the pressure back to around 2 500 kPa at 15 degrees ambient air For Service Technicians 17 3 6 13 Siddons Solarstream Pty Ltd 4 3 Evaporator Icing Up lf the evaporator ices up in cold ambient air temperatures work through the following list of possible causes and recommended checks 1 Low gas causing inefficient Heat Pump operation check the gas pressure which should be around 2 500 2 600 kPa when the tank water approaches 6
