    Expansion vessel – A suitable expansion vessel with a pre-charge pressure of 3 bar is supplied for fitting to all cylinders. All Solar 3C Cylinders must be fitted with a potable water expansion vessel (supplied) and the expansion vessel MUST be connected into the cold water supply after the pressure reducing valve.

    7. Discharge Arrangement The user must install a Tundish in a position so that it is clearly visible and positioned away from electrical devices. In addition, the discharge pipe from the Tundish should terminate in a safe place where there is no risk to persons in the vicinity of the discharge, be of metal and: (a) Must be at least one pipe size larger than the normal outlet size of the safety device unless its total equipment hydraulic resistance exceeds that of a straight pipe 9m long, i.e.
  • Page 16 Worked example The example below is for a ½”diameter temperature relief valve with a discharge pipe (D2) having 4 No elbows and a length of 7m from the tundish to the point of discharge. Maximum resistance allowed for a straight length of Ø22mm copper discharge pipe (D2) from a ½” diameter temperature relief valve is - 9.0 m.

    3Amp supply and a double pole switch with a minimum 3mm gap. From an economic and convenience point of view, it is intended that these controls operate in conjunction with other control packages for example: Solar 3C Solar Heating System or “S” and “Y” plan systems which incorporate a programmable time clock etc.

Check that all connections are made tight including the immersion heater. 9.3. Open the main stopcock and fill the secondary system first. Open successive taps (hot and cold) starting with the tap furthest from the cylinder.

  • Page 27: Introduction

    1. Introduction Solar 3C is a unique heating system that provides mains pressure hot water and space heating from a solar source. Water is heated in a triple coiled water heater by solar collectors. Heat is supplemented where necessary by a conventional boiler. The upper coil supplies heat from the cylinder to the heating system.

  • Page 28: System Operation Overview

    Solar 3C Cylinder, the back-up boiler/heat pump will automatically be switched off. The zone valve on the Solar 3C Jig will open, allowing the top/output coil of the Solar 3C Cylinder to provide the necessary temperature/energy to the heating circuit. This will cool the Solar 3C Cylinder promoting greater yield input from the solar collectors.
  • Page 29 The DHW zone value will open allowing water to flow through the cylinder heating the water. In addition, the Solar 3C mixing valve is switched to allow water through into the domestic hot water heating system. When the cylinder water has reached the correct temperature, the DHW zone valve is switched off so that only the heating circuit is supplied (as described in “Heating the dwelling”).

  • Page 30: System Components

    Note that the flow and return are connected to the Solar 3C Cylinder top coil in the reverse to that which may be expected because it concentrates the heat lower down and encourages a more even distribution of heat in the cylinder.

    6. Hot Water Commissioning 6.1. Check correct operation of the HW clock on Solar 3C Control Panel and the Cylinder stat. When the clock is on and the cylinder stat is “calling” the DHW zone valve should be energised. This is consistent with standard “S-Plan”...

  • Page 37: User Instructions

    Solar 3C guarantees all electrical and mechanical controls supplied with the Solar 3C Control Panel and Solar 3C Jig for a period of 1 year from the date of purchase provided that they have been installed for their intended use by a qualified person and have not been modified in any way.
