15.6 - Condensate trap and
neutralizing box maintenance and
cleaning
The condensate trap and neutralizing box must be checked every
year and cleaned if required. Follow the steps below to properly
inspect, recharge or substitute condensate neutralizing box and
media:
Monitor the level of the neutralization media in the box periodically.
The pH can be checked after the condensate has exited from pipe
“A” of Figure 9-2. Check the pH level every three months for the
fi
rst
year. Use a suitable pH test strip paper or an electronic pH meter
for precise measurement. The frequency of checking the pH level
can be reduced to every six months or every year depending on the
readings obtained compared to local water authority requirements.
The neutralizing media should be replaced when the pH level
drops below the minimum level of the local water authority. For
replacement media contact your local sales representative. How to
operate:
1. follow the steps in Section 15.2 to remove cover “E” of Figure 15-
2;
2. pull out the condensate box “A” (Figure 15-10);
CAUTION!!!
When the box is pulled out take care attention
before put it on fl oor, because is full of condensate water.
To avoid any leakage from the top, it is suggestable bend
it for 2 to 5 % in the discharge pipes direction to empty
some condensate water. Leaking condensate water may
cause severe property damage.
3. open cover “C” (Figure 15-11) in the upper direction;
4. inspect the condensate box making sure the collection box is
intact;
5. examine neutralizer medium and re
fi
ll as necessary with fresh
medium;
6.
fi
ll with fresh water until the water begins to
fl
ow out of drain;
7. re-install the condensate box;
WARNING!!!
The condensate collection box must
be fi lled with water to prevent fl ue gas emissions from
escaping during unit operation. Failure to comply with
this requirement can result in excessive levels of carbon
monoxide which can cause severe personal injury or
death!
8. open the manual gas shutoff valve;
9. restore electrical power to the heater;
WARNING!!!
The condensate neutralizer box must
be kept right installed into the unit, like shown in Figures
3-3 through 3-9 item “3”. Correctly reinstalling the
condensate collection into its position. If you don’t reistall
the condensate collection box into its correct position will
result in combustion gases will enter the room. This can
result in excessive levels of carbon monoxide which can
cause severe personal injury or death!
