9. ANCILLARY SERVICE CONNECTIONS
9.1 Heat Pump De-Frost Condensate Removal
Thought should be given to de-frost water from Heat Pump Outdoor units and the potential danger from
freezing if allowed to run onto a roof or similar area.
A separate drain tube plate is provided with the unit which fits over a 15mm sleeve and onto the bare
drain hole. Use 2-off N°12 self-tapping screws.
To prevent drain pipe from freezing in prolonged sub-zero temperatures, drain line heater boxes or
heater tape should be considered.
