Water Filter Retrofit Preparation Check
GPL HBA 10 & 11
Water Filter Retrofit Preparation Check
This check confirms that all necessary prerequisites, such as proper de-scaling and component readiness, have been met before installing a new water filtration system.
Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.
- Tank shows heavy scale that was not previously de-scaled: Stop — complete de-scaling before proceeding with retrofit
- Kit components do not match expected configuration: Stop — verify kit part number with supplier or manufacturer
- Fitting threads appear damaged or cross-threaded: Stop — do not force fittings; assess thread condition and replace if needed
- If the tank shows heavy scale that was not previously de-scaled, do not proceed with the retrofit and contact a qualified technician for de-scaling assistance.

technician-advancedsafe-when-isolatedVerify the machine is disconnected from electrical power and the water supply is shut off before beginning preparation checks.
Stop conditions- If the tank shows heavy scale that was not previously de-scaled, do not proceed with the retrofit and contact a qualified technician for de-scaling assistance.
- If fitting threads appear damaged or cross-threaded, do not force fittings; assess the thread condition and contact a qualified technician for replacement.
Expected: Initial condition is documented before deeper diagnosis.
