    2.- INSTALLATION 2.5.- UNIT INSTALLATION 1.- The EcoLean units could be installed outside or inside. 2.- See the minimum clearance diagrams for access - air supply to the batteries in the heating section of the unit. (see page 29) 3.- Assemble the unit on a resistant base, preferably concrete. To prevent vibrations, the concrete base should not come into contact with the building’s foundations.
  • Page 32 2.- INSTALLATION 2.5.- UNIT INSTALLATION 11.- For cooling or heat pump units the hydraulic system must contain the following components pump, buffer tank, expansion device, safety valve, water filter, flow switch. 12.- To obtain the total water system pressure drop add the unit pressure drop + water pipework + fittings and terminal unit pressure drops the water pump can be selected to provide the correct water flow across the heat exchanger.

    3.- COMMISSIONING AND OPERATION 3.1.- STEPS TO FOLLOW FOR COMMISSIONING THE UNITS PRE-START Before commissioning the unit check the following: 1.- Check that the voltage is the same as the rated voltage on the specification plate. 2.- Check that the supply to the control system is connected in accordance with the electrical diagram (if incorporates).

  • Page 35: Checking The Water Flow Rate

    3.- COMMISSIONING AND OPERATION 3.2.- CHECKING THE WATER FLOW RATE It is very important that the unit operates at the correct water flow rate. It is dangerous to leave the unit operating at a low flow rate as this could result in serious damage to components as well as the water exchanger. If the unit operates at too high a flow rate, this will also hinder optimum performance.
