Repair Instructions
The “Repair Instructions” chapter describes the approved
repair work for the HYDRONIC 16 / 24 / 30 / 35.
Where extensive repair work is to be carried out, it is sensible
to dismantle the HYDRONIC.
Mounting of the HYDRONIC involves the reverse sequence of
steps, but there may be some additional instructions which
need to be heeded.
Once all work on the HYDRONIC has been completed, a
functional test should be performed (see page 5).
Prior to working on the HYDRONIC, the following safety
instructions should be noted:
Danger of injury, burning and poisoning!
• Always switch off the HYDRONIC and allow to cool before
commencing work.
• Disconnect battery.
• Remove any excess pressure in the cooling system by
opening the radiator cap.
• Do not switch on HYDRONIC with the burner dismantled.
• Prior to removing the ignition spark generator, detach the
plug connections in the cable harness.
• The HYDRONIC must not be operated in enclosed spaces
such as garages or workshops.
Exception:
Where existing exhaust gas extraction is directly at the
exhaust pipe entrance.
Please note!
• Gaskets on dismantled components must be replaced.
• Where repair work is performed, examine all components
for damage and, if necessary, replace.
• Examine plug contacts, plug connections and lines for
corrosion and damage and, if necessary, repair.
• When a part needs to be replaced, only Eberspächer spare
parts may be used.
• After working on the coolant circuit, the status of the
coolant must be checked, and if necessary the coolant
must be topped up in accordance with the vehicle
manufacturer‘s specification.
The coolant circuit must then be bled.
• Operation or delayed shutoff of the HYDRONIC may only
be terminated in an emergency (see “Emergency cutout -
emergency circuit breaker” page 7) through disconnection
of the battery (danger of HYDRONIC overheating).
