When the water heaterBefore commissioning, device launching and adjustment works must be done only by qualified and trained personnel. Automatic control system ofthe ventilation unit must be properly adjusted to work adequately. Also, install measuring and operating devices in line with the provided guidelines.Air temperature sensors and air quality converters. Supply air temperature sensors and air quality converters (if additionally used) must bemounted as far as possible from the ventilation devices (within the confines of sensor cable) up to the first branch or turn of the air transportationsystem. This requirement is necessary to ensure the accuracy of measurement.Antifreeze protection. When external supply air water heater is used, it is necessary to properly install antifreeze protection from possiblefreezing of heat carrier. Antifreeze temperature sensor (TV) must be mounted in clamp on return pipe of the water heater. Capillary sensor of theantifreeze thermostat (T1) must be mounted on the water heater and its adjustment knob must be set at +5 °C.
