Page 11: How A Heat Pump Works
How a Heat Pump Works The heat pump essentially works in the same way as your refrigerator but in reverse. The Ecodan is hermetically ® sealed (no refrigeration piping involved) with R410A refrigerant, the cycle it completes to produce heat is known as the vapour compression refrigeration cycle: Step 1 The first phase begins with the refrigerant being cold and low pressure. -

Page 18: Heat Emitters
Please note that heat pumps provide lower flow temperatures to radiators than a conventional gas or oil boiler, the best performance is achieved with lower flow temperatures, Mitsubishi Electric recommend that flow temperatures in space heating should not exceed 45ºC if practical. Rather than the radiators turning on/off locally as with a fossil fuel boiler, heat pumps provide a more consistent lower flow temperature which allows for more efficiency and greater comfort. - Page 19 Electric recommend the use of such items. They can also be utilised on heating circuits if for example constant flow rates and variable flow rates need to be achieved on a single system.

Secondary Circulation The Mitsubishi Electric Pre-Plumbed Slimline Cylinder can be used with a secondary circulation pump. An appropriate WRAS approved bronze circulator should be used in conjunction with a non-return valve to prevent backflow. On large secondary circulation systems it may be necessary to incorporate an extra expansion vessel into the circuit to accommodate the increased system water volume, details of how to calculate this are found later in this manual. - Page 25 Compact Filter - Intaeco Duco All Mitsubishi Electric Pre-Plumbed Slimline Cylinders now have the Intaeco Duco compact filter factory fitted on the heat pump return pipework which is common to both heating and hot water zones.

Discharge Arrangement Position the inlet control group so that the discharge from both safety valves can be joined together via a 15mm end feed Tee. Connect the Tundish and route the discharge pipe. The discharge pipework must be routed in accordance with Part G3 of schedule 1 of the Building Regulations. - Page 30 Discharge Arrangement (continued) The discharge pipe (D2) from the tundish should be of metal or other material that has been demonstrated to be capable of withstanding temperatures of the water discharged. The discharge pipe (D2) should be at least one pipe size larger than the nominal outlet size of the safety device unless its total equivalent hydraulic resistance exceeds that of a straight pipe 9m long i.e.

Ecodan Installation ® Safety Precautions:- WARNING: Precautions that must be observed to prevent injuries or death. CAUTION: Precautions that must be observed to prevent damages to the unit. After installation, perform the test run to ensure normal operation. Then explain to your customer the “Safety Precautions” use and maintenance of the unit based on the information in the Operation Manual. - Page 32 Ecodan Installation ® (continued) Do not install the unit where combustible gas accumulates around the unit, it may cause fire or explosion. The outdoor unit produces condensation during the heating operation. Make sure to provide drainage around the outdoor unit if such condensation is likely to cause problems such as freezing over in cold weather. When installing the unit within the grounds of a hospital or a building where communication equipment is installed, you may need to take measures to reduce noise and electronic interference.

- Page 48 Only space heating operation can be supplemented by the boiler; hot water mode is not possible directly from the FTC4. When installing a boiler and Ecodan in conjunction with a Mitsubishi Electric Pre-Plumbed Slimline ® Cylinder, the position of the low loss header means that both heat sources will be common to both DHW and space heating.
- Page 49 This setup cannot be integrated onto a ‘standard’ Pre-Plumbed Slimline Cylinder without drastically increasing physical size and costs. Therefore the hydraulic and electrical configuration on the Mitsubishi Electric Pre-Plumbed Slimline Cylinder has been tailored to suit common UK 2 zone applications with a motorised valve controlling each zone directly connected to the primary circuit.

It is strongly recommended that this is done at regular intervals. Please check local regulations for the recommended frequency of heat ups.
- Page 56 The system can run in one of three modes, weather compensation, room compensation or fixed flow temperature. When using Mitsubishi Electric thermostats/sensors it is recommended that room compensation mode is used. When using third party thermostats for example on a multi-zone underfloor heating system either weather compensation mode or room compensation mode can be used.
