ä
Caution!
Always use original Itho Daalderop parts when
performing replacements or repairs.
This ensures the safety and correct operation of your
product and any warranty claim.
Note
Poor maintenance of the appliance can lead to higher
energy consumption, shorter life and unsafe
operation.
Claims against the factory warranty may be rejected if
it can be shown that the maintenance was not carried
out properly.
As a user, there are a number of things that you can
check and perform yourself (regularly):
●
Check for abnormal noises from the heat pump
during operation.
●
Inspect the pipes and system components for
leakage, corrosion and condensation.
●
Check the system pressure of the central heating.
The pressure of the central heating system should be
between 1.5 and 2 bar.
●
Check for air in central heating system; bubbling
sound in pipes.
●
Check the safety group; expansion water drips into
funnel during tap water heating.
●
Check the batteries of the thermostat.
●
To clean the outside of the product, it is best to use a
damp (use only water) microfibre cloth. If this does
not suffice, use liquid soap in combination with a
moist microfiber cloth.
Never use abrasive or aggressive cleaning products
that may affect lacquer or materials used.
Itho Daalderopadvises the user:
●
Have your appliance and heat pump system
inspected annually.
●
Maintenance should only be carried out if the
inspection indicates this.
●
The inspection and maintenance work must be
carried out by an approved installer or service
organisation.
●
Take out a maintenance contract with an accredited
installer or service organisation.
