BASIC TROUBLE SHOOTING
Calomax have manufactured water boilers in the UK for over 50
years. We are proud of our products and the back-up service we
provide
Properly maintained and serviced, a Calomax boiler should last
many years and we have no hesitation in providing a full 12
months (mainland U.K.) parts and labour warranty for all models.
Please complete and return the enclosed product registration form
as soon as possible
to activate this,
or register online at www.
calomax.co.uk .
In addition, the Clipper, Kudos and Quantum models carry an
additional 12 month back to base warranty.
Some factors are beyond our control and would invalidate the
warranty offered. These include:
Incorrect installation
High / Low water pressure
Incorrect voltage supply
Accidental damage
Limescale build-up
The last item can be a particular problem for water dispensing
equipment in hard-water areas. All hot water equipment should be
serviced and de-scaled by approved organisations on a regular
basis to avoid a damaging build-up of limescale.
Although our boilers incorporate scale-inhibitor technology, we
recommend that a taste, odour and scale filter should be fitted
where appropriate.

Service Partner Network and the range of filters and accessories
