3. EQUIPMENT CONTENTS4

A cold swimming pool is an unused swimming pool and in many upcountry areas swimming pools are too cold to use throughout the year and heating is required. There are a number of options available, but a particularly effective solution is the Dayliff Heat Pump. Heat Pumps utilise energy from two sources, heat from the ambient air and electrical power to run a compressor in a reverse refrigeration cycle, the compression process extracting heat from the ambient air for transfer to the pool water. The heaters are highly efficient operating at a Coefficient of Performance (COP), which is the ratio of energy output to direct energy input, of up to 6 times depending upon the environmental conditions. They are therefore very economical to run compared with fossil fuel alternatives though a pool cover must be used to ensure maximum heat retention. Heat Pumps are simply installed in-line on the filter return to pool pipe and include an integral controller and a durable housing suitable for outdoor installation. Particular features include:- • Low energy consumption for low running cost and low emissions for heating and cooling applications. • SPS-190 fitted with a plastic casing, larger sizes with a powder coated galvanised steel casing for long life • High efficiency compressor that uses environmentally friendly R410A refrigerant. • Advanced dual coil titanium heat exchanger for long corrosion free life • Built-in protection for the compressor, low water flow, high/low pressure and electrical overload • Fully automatic and simple to install with minimal plumbing and electric connections. Congratulations on selecting a Dayliff Heat Pump. They are manufactured to the highest standards and if installed and operated correctly will give many years of efcient and trouble free service. Careful reading of this Installation Manual is therefore important, though should there be any queries they should be referred to the equipment supplier.1. SPECIFICATIONS

The compressor, fan and water pump will stop working and restart again after the high pressure switch is reconnected. 3. If the high pressure switch is disconnected more than three times per hour, the controller will lock up this fault, and stop all the output no matter whether the high pressure switch is reconnected or not.Low Pressure Protection1. If the low pressure switch is disconnected less than three times per hour, display panel will show fault code with alarm.2. The compressor, fan and water pump will stop working and restart again after the low pressure switch is reconnected. 3.

5. OPERATION & MAINTENANCE5.1 Routine MaintenanceŸControl and protect the equipment.ŸPay close attention to whether all the operation parameters are normal during system working.ŸRegularly examine whether the electrical connection is loose, if not tighten.ŸRegularly examine the reliability of electrical components and change failed or unreliable components.ŸThere will be calcium oxidized or other mineral substance deposition on the surface of water heat ex-changer copper coil after long period of operation. This will impact the heat exchange performance and lead to high electrical consumption, high discharge pressure drop in air suction pressure and resulting in lower hot water production. To clean, use formic acid, citric acid, acetic acid or other organic acid.ŸThe dirt retention on the surface of evaporator fin may be cleaned using 6bar compressor blower, brushed by fine copper wire, or flushed by high pressurized water, usually once per month. If there is too much dirt, a paintbrush dipped gasoline may used to clean.ŸAfter long downtime, the following should be done before restart examine and clean the equipment carefully, clean the water pipeline system, examine the water pump, and fasten all the wire connections.5.2 Refrigerant Filling14Examine the refrigerant level from the display screen. Also check the air suction and exhaust pressure. If there is leakage in the refrigeration circulation system, examin air tightness and adjust if necessary.5.3 Leak Detection and Air Tightness ExaminationDuring leak detection and air tightness examination do not fill the refrigeration system with oxygen, ethane or other flammable harmful gas. Use compressed air, fluoride or refrigerant for such trials.5.4 To Remove the CompressorŸTurn off the power supplyŸDrain the refrigerant from the low pressure end, paying attention to reduce the exhaust speed.ŸRemove the compressor air suction and exhaust pipe.ŸRemove the compressor power cables, fixing screws and eventually the compressor.Use genuine replacement parts to ensure proper repairsNOTE

5.5 Routine Maintenance Conduct regular maintenance to make sure the unit is running in good condition.ŸIn the event of a fire turn off the power switch immediately and put out the fire with fire extinguisher.ŸTo prevent flammable gas from exploding: the unit working environment should be kept free from gasoline, ethyl alcohol and other flammable materials.ŸIf malfunction occurs, it should be attended by a qualified person who will find cause and eliminate it before restarting unit. Never boot the unit forcibly if the malfunction has not been eliminated. If there is refrigerant leakage turn off the power switch, if the unit can not stop by controlling switch, turn off the power.ŸDo not bypass the protection required for the unit, or else may damage the unit. and cause personal injury.15
