foundation must be solid and fastened; the bracket must be strong enough and antirust treated;
2) Please don’t stack substances that will block air flow near inlet or outlet area, and there is no
barrier within 50cm behind the main machine, or the efficiency of the heater will be reduced or
even stopped;
3) The machine needs an appended pump (Supplied by the user). The recommended pump
specification-flux: refer to Technical Parameter, Max. lift ≥10m;
4) When the machine is running, there will be condensation water discharged from the bottom,
please pay attention to it. Please hold the drainage nozzle (accessory) into the hole and clip it
well, and then connect a pipe to drain the condensation water out.
