[4] Using the Unit in Sub-freezing or Snowy Conditions In areas where temperature drops to freezing during the periods of non-use, blow the water out of the pipes or fill the pipes with anti-freeze solution. Not doing so may cause the water to freeze, resulting in burst pipes and damage to the unit or the furnishings. In areas where temperature can drop low enough to cause the water in the pipes to freeze, operate the unit often enough to prevent the water from freezing. Frozen water in the water circuit may cause the water to freeze, resulting in burst pipes and damage to the unit or the furnishings. In areas where temperature drops to freezing, use an anti-freeze circuit and leave the main power turned on to prevent the water in the water circuit from freezing and damaging the unit or causing water leakage and resultant damage to the furnishings. • Remove the snow off the unit before switching on the ON/OFF switch. • In areas where the outside air drops below freezing, leave the main switch turned on even when the unit will not be operated for four days or longer. Leave the switch on the water circulation pump turned on if the pump is connected to a separate circuit. • If the unit is left turned off for a while (e.g., overnight) when the outside temperature drops below freezing, the water in the water circuit will freeze and damage the pipes and the heat exchanger. • The recommended electric circuit has an anti-freeze circuit. For this circuit to function, the main power must be turned on. • If the water circulation pump is connected differently from the recommended way, make sure the circuit has some type of anti-freeze function*. (* A function that automatically operates the water circulation pump to prevent the water in the circuit from freezing when the water temperature drops.) In cold areas (where the lowest outside temperature drops below freezing), if power is not supplied while the unit is stopped during winter, make sure to completely drain water from the piping. Failure to do so may cause the residual water to freeze, resulting in damage to the heat exchanger. Before using the unit, perform a test run such as water fill test or air bleeding test again. Drainage method Procedure 1. Disconnect the outlet pipe. 2. Disconnect the inlet pipe. 3. Open the drain trap at the T-shaped part. 4. Completely remove water by blowing compressed air or nitrogen (cylinder) of 0.5 to 0.6 MPa into the outlet pipe. 1. Outlet pipe 4. Blow compressed air or nitrogen. 2. Inlet pipe 3.
