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

Don't put nger or sticker into the air inlet or air outlet. As the internal rotor high-speed operation may cause injury.WARNINGWhen a burning smell is detected, turn off the manual power switch immediately, stop operating, and contact Dayliff retailer.WARNINGWhen the unit needs to be removed, re-installed or repaired, contact Dayliff retailer or have a qualied person to do it. If the installation is not well done, it may cause failure, electric shock, re, leaking, etc.WARNINGThe heat pump must not be modied for other uses as it may cause electric shock or re.WARNINGThe installation base must be strong enough to support the weight else may damage the equipment.WARNINGBefore cleaning the unit, the operation should be stopped, and power switch turned off.WARNINGAvoid installations in such locations with mineral oil, air containing salty or corrosive gases, ammable compounds, strong electromagnetic waves or harsh environmental conditions.WARNINGEnsure there is enough space for installation and maintenance.WARNINGMake sure the air inlet and outlet are unobstructed for ease of maintenance.WARNINGRecheck the model, number, name etc, to avoid incorrect installation.WARNINGAvoid installation in an unstable place, such as car or cabinWARNING

When moving use four or more soft lifting belts to move the equipment.2. Use protective plate on the surface of the unit to avoid scratching and deformation.3. Recheck whether the foundation is level before hoisting the unit.4. The heat pump will produce condensation water, provide a drainage channel in the installation base during construction. 5. Include shock absorbers on the base surface to prevent vibration.4.3 Installation of the Pipeline1. Prevent air, dust and other debris from going into the water pipes and fix the whole system before installing the water pipe.2. Water inlet and outlet pipes should be insulated to prevent heat loss.3. Stable water flow should be maintained at all times.4. When moving the equipment water inlet and outlet pipe should not be used for carrying else will damage the equipment. Instead use holes provided on the base of the equipment.5. When connecting the water inlet and outlet pipes, two pipe wrenches shall be used to ensure the pipes do not turn around unnecessarily.5
