    Introduction Important Note to the installer The Mitsubishi Electric pre-plumbed cylinder is specifically designed to be installed in conjunction with an air source heat pump. The Mitsubishi Electric pre-plumbed cylinder is available with either an indirect single or twin coil.
  • Page 5: Key Facts

    Key Facts This version of the Mitsubishi Electric pre-plumbed cylinder is the fourth generation in terms of its control systems and the design of key mechanical components. As you would expect there have been many technological changes based around our experience of producing premium quality cylinders optimised to work with our Ecodan range of air source heat pumps.

    When running in timed mode it is possible to program setback periods throughout the course of the day. Either the main controller, a Mitsubishi Electric wireless controller or a Mitsubishi Electric hard wired sensor can be installed. Multiple sensors can be used on a single system with the ‘master’ sensor being rotated at set times throughout the day.
  • Page 10: 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.

    Low Noise Mode To activate low noise mode an optional 3 wire adaptor is required (PAC-SC36NA). This can either be wired into a manual switch or a timed version. The level of low noise mode which will be activated (as shown in the relevant graphs below and over the page) is determined by the combination of DIP switch settings (SW5-1 and SW5-2) on the outdoor unit as shown below.

  • Page 18: Heat Emitters

    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. 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 For connection of multiple heat sources using FTC4 control systems Mitsubishi 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 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.

This has been done following feedback from our installers and in an effort to ensure that every cylinder and Ecodan ®...
  • Page 26: Automatic Bypass

    Automatic Bypass Valve The Mitsubishi Electric pre-plumbed cylinder has a spring differential automatic bypass valve fitted as standard. This serves two purposes; it allows for the minimum flow rate of the Ecodan unit to be ® maintained and hence eliminates the possibility of high pressure or temperature faults due to insufficient flow rate.
  • Page 27: Circulation Pumps

    If minimum flow rate cannot be achieved with the pumps on speed 3 then additional pumping capacity may be required – please contact Mitsubishi Electric Pre Sales Technical Support (01707 278666) for further advice. The second (space heating) circulation pump is controlled by the 2 port valve motor outputs for all 2-zone systems as shown by the below wiring diagram.

    .Anti-vibration mountings (i.e. Tico-pad) should be installed under the mountings of the heat pump to prevent excessive vibration. Rubber anti-vibration fix it feet can be purchased from Mitsubishi Electric which have the dual purpose of raising the unit from ground level (useful in snow prone locations) and reducing vibration.

    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 31 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.

When installing a boiler and Ecodan in conjunction with a Mitsubishi Electric pre-plumbed cylinder, the ® position of the low loss header means that both heat sources will be common to both DHW and space heating.
  • Page 50 This setup cannot be integrated onto a pre-plumbed cylinder without drastically increasing physical size and costs. Therefore the hydraulic and electrical configuration on the Mitsubishi Electric pre-plumbed cylinder has been tailored to suit common UK 2 zone applications with a motorised valve controlling each zone directly connected to the primary circuit.
