8 - CORRECTIONS TO BE MADE WHEN USING ANTI-FREEZE • IMPORTANT: Use monopropylene glycol; a minimum rate of 15% to 20% is needed to avoid any risk of corrosion. PRINCIPLE OF USING THE CURVES Correction factors A - Choose the percentage of glycol according to the minimum temperature to protect the hydraulic circuit against frost. B - Example: Protection at an external temperature of -15°C, which gives 30% glycol (freezing points curve).

Auxiliary electric heating: • The heater consists of immersion heaters each rated at 8 kW (400 V, 3-phase), mounted on the tank. • These immersion heaters are controlled from a specific unit with 2-stage control, and the power feeders are protected by circuit breakers and a master switch (power supply separated). • Backup is authorized with the 2nd stage, although is triggered only if the generator is out of service. • The power supply for this heating system is connected separately (3-phase 400 V).
