1.4.1.Points to Consider Before Contacting the Authorized Service
First of all, we would like to thank you for choosing and using the “Rima Condensing Boiler”. Below
is a list of things to do before calling the Rima Authorized Service.

Protect your device against factors that may damage the packaging and the device (moisture,
water, impact, construction materials, etc. ) during the transport and subsequent assembly of
the device. The boilers shall be installed on a stable, firm ground. In case of a surface which is
not suitable for supporting of the boilers and the connection equipment, a suspension system
with a metal profile shall be used.

The installation water shall be conditioned by considering whether the system is a new heating
system to be installed or an heating system to be transformed. If the installation to be used for
the system is old or if it shall be transformed, the water in the installation shall be completely
drained and water shall be conditioned (cleaning shall be performed and a preservative shall
be used). We recommend the use of plate heat exchangers in such systems particularly. The
presence of blockages in the heating installation such as dirt, sediment, burrs, iron dust, lime,
etc., adversely affect the operation of the boiler. This may cause inefficient operation,
overheating, noisy operation, and damage to the heat exchanger of the boiler over time.
Installation water shall be conditioned and preserved in new installations.

For the hardness of the water, the hardness value appropriate to the capacity shall be
determined in accordance with the table given below.


Water containing sediment or of unknown content such as well water and transport water shall
not be used. Use of any chemicals by adding them to the installation without the approval of
the manufacturer shall render the products void of warranty. As Rima Heating Systems, we
recommend use of water treatment products with Sentinel X100, X300 or X400 brands. Use
neutral, non-acidic and non-alkaline cleaners. Any damage to the product or installation that
may occur without taking the approval of the manufacturer in applications performed using
the products of different companies is out of warranty cover. It is the user’s responsibility to
ensure that the water to be circulated in the installation is clean.

Sub-boiler pumps, hydraulic sets, balance vessels, sediment traps, air separators to be used in
the installation shall be selected as suitable to the boiler and heating installation.
