3.2 REFRIGERANT TYPE AND INSTALLEDLOCATIONThis heat pump contains R32, which is anenvironmentally friendly refrigerant with a GWP(Global Warming Potential) of 675. R32 has the safetyin use classification of A2L, being low toxicity andlower flammability. In practical terms it is very difficultto ignite an A2L refrigerant, but this classificationrequires a risk assessment to be undertaken for thepossibility of refrigerant being released by accident intoan area connected to the heat pump, considering theapplication, location of components, and the installedrefrigerant charge. This installation guidance can formthe framework for such a risk assessment for theinstallation.ModelAll flammable refrigerants will not ignite if theconcentration level in a room stays below their lowerflammability limit (LFL). European standard EN378defines requirements to remain far below the lowerflammable limit in case of accidental leakage. Bychoosing the location as dictated by EN378-1:2016the probability of forming a flammable atmospherecan be eliminated. Please refer to the minimumarea for each product and the interpretation belowregarding locations of heat pump and swimming pool.This information is provided as a guide only and doesnot supersede the regulations or health and rantchargeR32 kg0.80.81.7Minimum aream²5.45.424.6Notes*Assumed worst case for access category: a - general access and locationclass: I - mechanical equipment in occupied space; both as defined in line withEN378-1 2016 section 5.1 table 4 and section 5.3*Minimum Area is calculated in line with section C.2 on EN378-1 2016(calculation C.2).INTERPRETATIONPlease refer to the installation situations below for howto apply the minimum area stated above.Pool inside and heat pump outside:The pool hall must exceed the minimum arearequirement shown above.Pool outside and heat pump outside:Automatically meets the minimum area requirementbecause outside space is unlimited.Pool inside and heat pump inside a plant room,isolated from the pool hall:The pool hall must exceed the minimum arearequirement shown above.Pool outside and heat pump inside a plant room:Automatically meets the minimum area requirementbecause the room must open to the outside for heatpump airflow and the outside space is unlimited.Pool inside and heat pump inside a plant room,ventilated to the pool hall:The pool hall and plant room combined must exceedthe minimum area requirement shown above.1005759 ISSUE 313

3.4 PLUMBINGIMPORTANTBefore installing the heat pump ensure theblanking disks are removed from the pool waterin/out connections. These should drop out whenthe adaptors are unscrewed.Supported pipework1. Ensure that bypass is installed and set to achievethe recommended flow rates stated in the datasheet.2. Ensure that the condensate drain kit supplied isfixed and is drained to a drain or soak-away.3.5 INITIAL CHECKSWateroutWaterinStart the filtration pump before the heat pump isturned on and turn off the heat pump before thefiltration pump. It is recommended to turn off the heatpump prior to backwashing.Before starting the heat pump, please check forany leakage of water; and check/set the requiredtemperature on the controller, and then turn on.3. Inlet and outlet pipework must be supported toavoid excessive strain on the connections.4. Water quality must be maintained. See warrantyconditions.In order to protect the components, the heat pumpincorporates time delays. When starting heating/coolingthe fan will run for one minute before the compressorstarts. The heat pump runs for a minimum of 5minutes. When the heat pump stops heating/cooling,or is turned off by the user, the fan will continue to runfor one minute.After starting up, check for any error codes or abnormalnoise from the heat pump.1005759 ISSUE 315

OWNER/INSTALLATION MANUAL3.6 ELECTROLYTIC CORROSION IN SWIMMINGPOOLSElectrolytic corrosion will occur when dissimilar metalsthat are in contact with each other create a potentialdifference between themselves. Sometimes separatedby a conductive substance known as an electrolyte, thedissimilar metals will create a small voltage (potentialdifference) that allows the ions of one material to passto the other.Just like a battery, ions will pass from the most positivematerial to the more negative material.Anything more than 0.3 volts can cause the mostpositive material to degrade.A swimming pool with its associated equipmentcan create this effect. The pool water being an idealelectrolyte and components of the filtration circuit,heating system, steps, lights etc providing the dissimilarmetals needed to complete the circuit.Whilst these small voltages are rarely a safety threat,they can create premature failure through corrosion.Not dissimilar to corrosion through oxidation, electrolyticcorrosion can cause complete failure of a metallicmaterial in a very short period of time.In order to prevent this type of corrosion all metalliccomponents in contact with swimming pool watershould be bonded together using 10mm² bondingcable. This includes non-electrical items such as metalfilters, pump strainer boxes, heat exchangers, stepsand handrails. It is highly recommended that bondingbe retrofitted to existing pools, which may not beprotected by this system.163.7 ELECTRIC WIRING AND SUPPLYAll electrical work to be carried out in accordance withl.E.E.regulations, latest issue, or local codes of practiceas applicable. .The machine should be installed in accordance withEMC2004/108/EC.Always isolate the main ower supply before removingmachine covers.The machine power supply must incorporate thefollowing. Fuses or motor type circuit breakers (aMFuse / MCB type C) to specified rating (see datasheet).When using a fuse, H.R.C. fuses are recommended. Anisolator which disconnects all poles must be must fittedwithin 2m and in line of sight of the heat pump. Theisolator must have a minimum of 3mm air gap whenturned off.All units must be correctly earthed/grounded and itsown separate type F RCD earth leakage trip installedwhich protects the machine only.The following limits of operation must not be exceeded.Failure to provide the necessary voltages will invalidatethe warranty. This voltage must be available at the heatpump whilst running. The voltage must not drop belowthe above figures when starting the compressor.MinimumMaximum207V253VVoltageSingle phase machinesCycle frequency (50Hz) 47.5Hz52.5Hz1005759 ISSUE 3

OWNER/INSTALLATION MANUAL3.9 POOL PUMP OVERRIDETERMINALS P1/P2For installations where the pool filter pump runscontinuously, these terminals do not need to be used.For installations where a timeclock controls the poolfilter pump, and the same pump provides water flowto the heat pump, the heat pump can override “pumpoff” periods to ensure the pool is heated/cooled. Toactivate this setting please speak to your installer.This feature operates by over-riding the timeclockwhenever the controller measures a water temperaturethat needs heating/cooling. If the pool does not needheating/cooling the filter pump will be turned off untilthe controller next measures a water temperaturethat needs heating/cooling. If the pool needs heating/cooling the heat pump will continue to run the filterpump and heat/cool the pool.When installed in parallel with the timeclock, the poolfilter pump will run when:This feature will reduce the pool filter pump run time tominimise pump energy usage.a) a period of “pump on” has been set on the timeclock for filtration purposes.b) a period of “pump off” has been set in the timeclock and the heat pump runs the pool filter pump fortemperature sampling and if the pool subsequentlyrequires heating/cooling.Terminals inheat pumpP1Customer’s external pump/filter time clockSeparate supplyLNEFuseLRelayP2230V coilPool pumpstarterNLSingle phasewater pump18N1005759 ISSUE 3
