Field of application
Pump group SIMPLE is used in high-temperature heating systems when there is a need to warm up low-temperature
heating system - radiant heating (floor / wall heating). The set consists of mixing valve with thermostatic head,
non-return valve, spacer, immersion sleeve, contact control thermostat, two holland connectors and two ball valves
with holland conectors. Mixing set controlls secundary heating circuit by which it controlls the temperature in room
(depending on the needs). Supply flow temperature can be regulated to a constant value or according to the needs
of the user.
Assembly
Pump group SIMPLE for underfloor heating can be mounted directly on high – temperature heating system. The
mounting position is arbitrary. By using the connectors with free moving nut we can mount the mixing set directly to
the distributors for floor heating systems. Connections on the pump are not completely screwed in, as the installer
can adjust the position of the pump to its needs. After assembly, the installer must check connections on the pump
for water tightness. In case there are impurities in the medium (hard water, dust, etc.) it must be installed a filter,
otherwise impurities may damage the valve seals. Included contact thermostat Afriso GAT / 7HC protects the system
from overheating. Authorized installer set the max. temperature on the outlet and mounts the contact thermostat on
the upper mixing unit (position 6 on components picture, page 3).
Brass
HERZ use top-quality brass that responds to the latest European norms DIN EN 12164 and DIN EN 12165. Parts of
the pump group Simple are made from brass due to its good strength and excellent corrosion resistance.
Pursuant to Article 33 of the REACH Regulation (EC No. 1907/2006), we are obliged to point out that the material
lead is listed on the SVHC list and that all brass components manufactured in our products exceed 0.1 % (w / w) lead
(CAS: 7439-92-1 / EINECS: 231-100-4). Since lead is a component part of an alloy, actual exposure is not possible
and therefore no additional information on safe use is necessary.
