10 OK 1 2? 2. Connection 2.3. Steam or Hot Water Connection Must be installed by an authorized technician and in accordance with local regulations. Note: On site, make sure that the pressures and temperatures for the heating medium given in the installation plan cannot be exceeded General information Connect supply and return pipes according to installation plan. All connections are equipped with necessary fittings and valves as standard Insulation All pipes should be insulated. Insulating material should be water, heat and shock proofed Adjustment of manual shut-off valve with flow reducer for steam and hot water supply The built-in manual shut-off valve is equipped with an adjustment device to limit the heating supply medium. A special tool is necessary for adjusting the valve-seat. The correct adjustment is very important, particularly for higher pressures, and therefore must be carried out by a HOBART-trained service technician before first run or when changes are made to the plant on-site. The optimum adjustment is achieved when the nominal temperature of the booster can just be held during continuous operation while the valve is opened to maximum. If the valve is opened too far, pressure shocks may occur when the solenoid valve closes. This could cause damage to the installation. If the valve is closed too far, the required heating-power cannot be achieved BA
