Installation
●
The inlet has a center connection port and the
outlet has an offset connection.
●
Install the neutralizer on the wall or the floor and
secure it using the brackets supplied with the kit.
●
If the neutralizer is installed horizontally, rotate
the neutralizer to position the outlet at the
highest point (Figure 1).
●
If the neutralizer is mounted vertically, ensure that
the outlet is higher than the inlet (Figure 2).
●
Ensure that the condensate runs freely to the
drain.
●
Ensure all connections are made to prevent
the backflow of condensate. Use corrosion
resistant piping and secure all piping to prevent
movement.
Note
Do not install condensate piping in
areas where the temperature drops
below freezing point. Protect piping in
high pedestrian areas from damage and
vibration.
●
For increased safety when the condensate drain
blocks, install a Y-fitting. Connect the Y-fitting as
shown in the installation diagram and ensure that
the condensate runs freely to the drain.
●
Ensure that the discharge connection is
accessible. Access to the discharge connection is
required for maintenance and pH testing.
●
If there is insufficient gradient for drainage, install
a drainage pump designed for boiler and water
heater condensate removal.
