Page 23 IMPORTANT NOTICE! • As long as there are conditions favourable for the creation of condensate ensure the unit condensate outlet is connected to an appropriate waste system. • The use of a condensate siphon is only recommended where gravity assisted drainage is achievable. • Ensure the condensate syphon is installed with sufficient height difference from the unit so that the conden- sate can drain freely by gravity. • Ensure that the condensate is routed to a suitable outlet. • If the pipework connecting the outlet from the unit to the condensate drainage system is installed on a loca- tion that can freeze the pipe must be insulated or equipped with a frost pipe heater. • Ensure that the condensate discharge point height does not exceed the maximum head of 12 m for the con- densate pump. • If the condensate pumps is fitted ensure it is properly mounted so pipes and hoses will not kink or become detached in operation. Pipe clips should always be used. • For additional information on the pump installation, operation and maintenance please refer to the IOM pro- vided with the pump.
