    MOUNTING AND SET-UP While mounting the unit provide enough access for maintenance or repair work. The minimum recommended clearances between the unit and the adjoining walls are given in the figure below. Before starting the unit make sure that the rotary heat exchanger cells are clean and free from damage. Check the belt tension. The tension force is regulated by the spring on the motor suspension mount.
  • Page 12 www.ventilation-system.com WATER HEATER CONNECTION Use a pipe spanner for connection of a water heater. Do not apply excessive force while tightening the water works fittings when connecting a water heater. A pipeline system connected to a water heater is designed for normal operation in premises with air temperatures above 0 °C! If the temperature is expected to drop below 0°C it is necessary to provide appropriate thermal insulation or air heating at the site of unit operation.
