Water Exchanger Connection; Connection Of The Unit To The Existing Hot Water Distribution System - Xvent Atacama 2 Instruction Manual

3.5. Water exchanger connection

3.5.1. Connection of the unit to the existing hot water distribution system

- Connect the unit to the heating system using a flexible connection (e.g. flexible hoses – with braided
armour). The heating system piping must not put any load on the exchanger throats.
3.5.2. Water exchanger connection
- Water supply and drainage necks are marked on the water exchanger collectors. To tighten the connected
piping to the unit, use the hexagonal profile on the water exchanger neck. This prevents the exchanger
outlet from being overturned, which may result in irreversible damage to the water exchanger.
After connecting the water exchanger to the heating system, a pressure test of the unit connection is
-
recommended.
- The tests must be carried out by a person qualified in this field with knowledge of the applicable
regulations and standards of the country concerned.
- We recommend installing shut-off valves on the water exchanger inlet and outlet for the shut-off of the
heating medium, or to allow the unit dis-assembly without the need to drain water from the heating
system.
