• Avoid routing flexible drains in areas likely to be crushed (e.g., under tiles or behind cladding)
• Where needed, protect drain lines in rigid PVC conduit or sleeves
• Replace flexible drain hose with rigid where necessary
• Confirm clear drainage before handover
• Photograph drain routes prior to concealment (e.g., tiling, boxing in, slab pours)

Refrigerant Charging – Vacuum and Commissioning

• For split and multi systems with shorter runs, vacuum must reach ≤ 50 microns
• For VRF systems or long runs (60m+), vacuum should aim for < 100 microns, depending on conditions
• Vacuum performance should be monitored carefully and achieved using regularly serviced vac pumps
• Record refrigerant charge and clearly label outdoor unit with the amount added
• Confirm system pressures align with manufacturer specs during commissioning
