Zip AQ2 Expansion vessel and check valve
Product Code: AQ2
When installing small unvented water heaters, it is essential that the correct accessory packs are used.
For use with Zip Aquapoint & Varipoint 10 and 15 Ltr Unvented Units Only
The expansion vessel when fully charged will absorb all expanded water produced by the unvented heater during normal operation.
The check valve prevents backflow of hot water and eliminates any possibility of cross contamination between cold and hot water.
The expansion valve opens at 6 bar (87 psi). It acts as a backup to the expansion vessel.
Installation: Pack U2 where used, must be installed in close proximity to the heater on the inlet side.
