It cannot protect against very heavy impacts. COMPRESSOR NOISE INSULATION JACKET Each compressor is fitted with a compressor acoustic jacket this provides attenuation of the compressor noise that radiates from the unit when in operation. ANTI-VIBRATION To install under the unit, to avoid transmission of vibrations, to the floor where unit is installed, while unit is operating.

Page 27: Site And Shipping Guidance
When the unit is received, it should be checked to assure that there are no bumps or other damage, following the instructions on the packaging. If there is damage, the unit may be rejected by notifying the LENNOX Distribution Department and reporting why the machine is unacceptable on the transport agent’s delivery notice. -

2.- INSTALLATION 2.7.- UNIT INSTALLATION 1.- The EcoLeanTM 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 28). 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 2.7.- 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.

Page 34: Commissioning And Operation Page
3.- COMMISSIONING AND OPERATION 3.1.- STEPS TO FOLLOW FOR COMMISSIONING THE UNITS 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) 3.- Check that the main switch is ON (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. -

The resistance guide below is an attempt of give a picture of the corrosion resistance of the stainless steel of the type AISI 316 and pure copper in the water, to a number of important chemical factors. -
Page 37: Preventive Maintenance
4.1.- PREVENTIVE MAINTENANCE EPREVENTIVE MAINTENANCE PREVENTS COSTLY REPAIRS. We recommend regular and thorough servicing of the LENNOX unit. It is therefore advisable to ask your dealer about maintenance contracts. Check maintenance of the following points (depending on the operating conditions maintenance every 6 months may be necessary). -
Page 38: Corrective Maintenance
4.- MAINTENANCE 4.2.- CORRECTIVE MAINTENANCE - Take very special care if 4-way check valves are to be replaced since these have internal components that are very heat- sensitive such as plastic, teflon, etc. - If a compressor must be replaced, disconnect it electrically and un-braze the suction and discharge lines. Remove the securing screws and replace the old compressor with the new one. - Page 39 NOTES...
