## 🛠️ Service Notes

-   Three heat exchangers sit in this group at very different sizes - this one at 23.587 kg, 3828469 at 14.22 kg and 3828574 at 35.38 kg - so check the fitment and supersession chain rather than picking by appearance
-   Renew the end cover gaskets, seals and any sacrificial anode with it, and check the raw water pump impeller for the debris that blocked the old stack
-   At 23.587 kg this needs lifting support rather than being handled by hand
