INSTAllATION
4.4.2.3 Installation of the condensate drain siphon –
neutralisation unit – sewer system
When installing the siphon and condensate
drain, the project engineering guidelines for
condensate drains must be complied with,
NOTICE
Blockage by granulate dust
Fine granulate dust can block the neutralisa-
tion unit and the condensate drain.
• Follow the commissioning or maintenance
instructions in the separate installation/
operating instructions of the neutralisation
instructions.
1. Screw double nipple (1, Fig. 34) and siphon (2) onto
the condensate drip tray and tighten securely (con-
nection must be tight!).
2. Place, install and commission the neutralisation unit in
accordance with the installation and operating instruc-
tions supplied with the neutralisation unit.
3. Fill the siphon and the neutralisation unit with water.
After installation, before commissioning of the
boiler, the following must be carried out:
•
Check condensate flow.
• Functional check of all existing electrically op-
erated components of the neutralisation unit
• pH value measurement (before and after
the neutralisation unit)
• Check all connections for leaks:
- Double nipple – siphon
- Siphon – neutralisation unit
- Neutralisation unit – sewer system
•
Check condensate outflow.
4.4.2.2 Installation of the condensate drain siphon –
condensate pump – sewer system at higher level
When installing the siphon and condensate
drain, the project engineering guidelines for
condensate drains must be complied with,
1. Screw double nipple (1) and siphon (2) onto the con-
densate drip tray and tighten securely (connection
must be tight!).
2. Place the condensate pump (4) as close as possible
to the siphon (2), depending on the available space.

3. Establishing hose connections:
- Hose connection (3)
siphon – condensate pump
- 0.5 m hose is included with the condensate pump
purchased at Hoval.
- Hose connection (5) condensate pump – drain
- Hose is included with the condensate pump pur-
chased at Hoval.
4. Route the cable to the condensation pump (4) to the
control and connect according to the wiring diagram.
After installation, before commissioning of the
boiler, the following must be carried out:
•
Check condensate flow.
• Check the function of the switching points of
the condensate pump:
- Liquid level switch for pumping out
- Liquid level switch for locking the burner
• Check all connections for leaks:
- Double nipple – siphon
- Siphon – condensate pump
- Condensate pump – drain
•
Check condensate outflow.
