INSTALLATION
Supply water piping may be of any code-approved material (copper, steel, or
plastic). The fill valve connection size is a 3/4" pipe thread (DN20) fitting. In
cases where water hammer may be a possibility, consider installing a shock
arrestor. Water pressure must be between 25 psi and 80 psi (175 kPa and
550 kPa).
Important:
Install unions in the water supply and drain lines as shown in
Figure 19-1 to allow tank removal.
