8INSTALLATIONIdeal airtherm - Air Source Heat Pump - Installationa. A separately fused single phase supply is required. Withall power switched off, remove the electrics access panelto gain access to the terminals in the electric box. Thesupply cable, entering the unit through knock outs in thepanel, can then be fed through to connect into the live/neutral/earth terminals.b. An MCB type C or D fuse must be used. (Refer to datasheet on page 16 of this manual).c. A local isolator should be fitted within 2 feet of the unit tocomply with I.E.E. regulations. Power to the unit isindicated by the red indicator light on the console (mainslamp).d. A separate fused spur is normally used to supply thecentral heating programmer and controls.e. There are 10 connections to be made between the Idealheat pump and the control wiring centre. A multi core cablewith sufficient capacity will need to be provided andinstalled. In most cases a 12 core 0.5mm control cable isused.ELECTRICALELECTRICAL CONNECTIONSa. The electrical connections diagrams are on pages 9 and10 of this manual.b. The wiring junction box is located behind the accesspanel below the unit’s control panelc. For the heat pump to operate, you must have a live signalinto terminal 1 (space heating) or terminal 9 (DHW).INTERNAL WIRINGa. Internal wiring diagrams are on pages 11 and 12 of thismanual.b. External wiring will depend on the heating system designand is covered in the system design section of thismanual.f. The unit may be live even when the mains lamp is off dueto live feeds from the external control system. The‘programmer live’ light on the control panel confirms thepresence of a supply.g. The heat pump can operate in one of two modes, eitherset as supplied, with the unit biased to hot water, or withno bias for hot water or heating.h. Ideal Boilers would always recommend a system with theheating biased to hot water. However if room heating andhot water heating are required at the same time, the linkbetween terminals 11 and 12 should then be fitted. Thereis then no bias between room heating and hot waterheating.Notes:-i. Where the link is fitted the unit will deliver 65ºC flowtemperature during periods of DHW demand and thismust be considered at system design withconsideration to this temperature feeding radiators orunder floor heating at these times.ii. The link cannot be fitted when the heat pump isplumbed in to a ‘W Plan’ system. |
