5Ideal airtherm - Air Source Heat Pump - InstallationGENERALINTRODUCTIONThis installation manual is accompanied by a user guide (seereverse of this book), a commissioning record sheet and awarranty registration card, all of which should be left with thehouseholder. The user guide explains how the system works,how it is controlled and what to do in the event of a problem.The commissioning record sheet must be completed as itsproduction will be required in the event of a warranty claim.HEATING WITH A HEAT PUMPThe Ideal heat pump is designed to operate up to 65 o C watertemperature for the domestic hot water delivery, and negatesthe need for direct electrical heating in the form of an electricalemersion heater. The unit also provides space heatingtemperatures variable from 35 o C to 55 o C.Heat pumps for domestic heating are a fully proven technologywhich will give many years of trouble-free service. Ideal HeatPumps which are MCS approved have been specificallydesigned for optimum operation in the UK’s climate.However, unlike an oil or gas boiler which may be oversized forthe heating demand of the property and therefore regularlycycles on and off, a heat pump is closely matched to the heatdemand and is designed to run for long periods withoutswitching on/off.The following steps must therefore always be taken to ensurea successful installation. Major problems can occur if they arenot taken and failure to comply will invalidate the warranty.a. SAP or equivalent heat loss calculations must beestablished with the results recorded on thecommissioning sheet.b. The heat pump must be correctly sized in relation to thecalculated heat losses.c. The space heating system must be capable of satisfyingthe heat demand at the water flow temperature set for theheat pump. This is particularly important where retro-fittinga heat pump to a radiator system designed originally for aDelta T of 60 o C, as the heat pump will run at a Delta T of30 o C. In this situation, you will normally need to fit largerradiators.d. The electrical supply must be adequate to meet the startcurrent demand.e. The heat pump and the associated heating system must becommissioned in accordance with the procedures laiddown in this manual.A heat pump may be fitted on a stand-alone basis (monovalentsystem) to satisfy the full heating and hot water demand of theproperty or in parallel with an existing boiler (bivalent system).In the case of a bivalent installation the heat pump is sized toprovide a variable proportion of the annual heating requirement(say 85%) with the existing boiler integrated to deliver thebalance on the coldest days. In bivalent systems, the heatpump is sometimes only linked to the space heating systemwhich eliminates the requirement to fit a new DHW cylinder.Standard designs for several different configurations, includingplumbing and electrical circuits, are included in this manual.REGULATIONSThe Ideal airtherm models confirm• BS EN60335-1:2002 &2-40:2003, and therefore comply withthe Low Voltage Electrical Equipment Directive 73/23/EEC;93/68/EC.• BS EN ISO 12100-1:2003, BS EN ISO 12100-2:2003, BSEN ISO13857:2008: BS EN ISO 13850:2006, and thereforecomply with the Supply of Machinery (Safety) Directive 98/37/EC.• BS EN55014-1:2000+A1:2001+ A2:2002, 14-2:1997+A1:2001, EN61000-3-2:2000, -3-3:1995 + A1:2001,-4-2:1995, -4-3:1996, -4-4:1995, -4-5:1995, -4-6:1996, -4-11:1995.and therefore comply with the ElectromagneticCompatibility Directive 2004/108/EC.• Comply with the Pressure Equipment Directive 97/23/EC,Fluid Group 2,Category 1.• Compliant to RoHS Directive 2002/95/ECSAFETY PRECAUTIONSa. The unit must be securely installed on a structure that cansustain its weight. If mounted on an unstable structure, itmay fall causing injury or damage.b. If the heat pump is installed in an enclosed area, sufficientventilation must be provided so as not to impede the air flowthrough the unit and to prevent the concentration ofrefrigerant gas in the room building up in the event of a leak.(See diagram - page 6)c. All electrical work must be performed by a qualifiedtechnician and comply with the latest I.E.E (17th ) Regulations.The machine should be installed in accordance with EMC2004/108/EC.d. Electricity to the unit must be supplied through dedicatedpower lines and the correct voltage and circuit breakers mustbe used. Power lines with insufficient capacity or incorrectelectrical work may result in electric shock or fire. Theelectrical ratings of Ideal heat pumps are included in thedatasheet on page 16 of this manual. |
