9 - SYSTEM START-UP
9.6 - Electric heater
9.6.1 - Electric heater pre-commissioning checks:
Warning!
Follow the safety instructions (see § 2 - SAFETY INSTRUCTIONS).
■ Check for the presence of an air flow detection device.
■ Make sure the safety thermostats are electrically connected. Check the pin couplings (star as standard) as per the wiring diagram.
■ Check the tightness of the connections: Tightening torque 4 Nm.
■ Remove any impurities using a vacuum cleaner and/or a cleaning product.
Do not use a cleaning product or cloths with detachable fibres (e.g. cotton/wool) on the heating elements.
■ Make sure the electric heater casing is clean and free from foreign objects
9.6.2 - Electric heater system start-up:
■ Never operate the heater when the fan is stopped.
■ Check whether the safety thermostats operate correctly.
■ Check the fan delay time that must be no less than 1minute, and to be adjusted as per the damper actioners rotary speed.
■ For variable flow operation, adapt the heater power to the air flow rate.
■ Check the power absorbed by each supply phase for the electric heater and compare these values to those shown on the data
plate.
■ Retighten the connections after 48 hours of operation.
ELECTRICAL DANGER: Door for directly accessing the electrical connections. Lock the door with the key once closed.
9.7 - Steam humidifier
For the adiabatic humidifier, see the IOM for the adiabatic evaporative humidifier.
Warning!
Follow the safety instructions (see § 2 - SAFETY INSTRUCTIONS).
9.7.1 - Pre-commissioning check
■ Check the cleanliness of the rails and the pan and the position of the eliminator cells and look for any damage.
■ Make sure the water shut-off valve to the humidifier is open.
■ Check the condition of the pipe assembly (supply/drainage/condensates).
■ The drain pan siphon (option) must be activated during commissioning.
■ Make sure the box is clean and free from foreign objects. Remove any condensate using a vacuum cleaner and/or a cleaning
product.
■ Check the wiring.
■ Check that the humidity sensor (option) is operating correctly.
■ Follow the instructions in the manual from the manufacturer of the standalone device supplied with the unit.
9.7.2 - System start-up
■ Follow the instructions in the manual from the manufacturer of the standalone device supplied with the unit. If the control (option)
is supplied by us, consult the control manual.
■ In this phase of the system start-up, it may be a while before the nominal production rate is reached. This depends primarily on the
conductivity of the supply water, and may be several hours.
