1. FUNCTIONAL DESCRIPTION
The ratiotherm WP Max-Air air heat pump is designed as a split heat pump and
characterised by very quiet operation. By using the heat pump, the stored energy of
the ambient air can be easily tapped. No earth or well construction work is necessary.
The maximum flow temperature is 62°C. Thanks to its variable-speed compressor, it can be
infinitely adjusted in output and is therefore particularly efficient. This feature is complemented
by Smart Grid capabilities, which makes it perfectly suited for power-to-heat applications as well
as network-related applications. An optional hybrid heat exchanger makes it easy to use another
environmental source. Solar collectors or heat recovery systems, for instance, can be connected here.
ADVANTAGES
• Easy installation without expensive excavation
work
• Increased efficiency possible with optional
hybrid heat exchanger
• Maximum flexibility thanks to speed-controlled
inverter operation
• Integrated energy management (SG capable)
• Very quiet outdoors
• With ratiotherm components, a completely
compatible, future-proof system

ATTENTION! DAMAGE POSSIBLE
• Use only by qualified and instructed persons.
• Only for intended use.
• Any other use constitutes misuse.
CAUTION! DANGER OF SCALDING
• The outlet temperature at the hot water taps can be up to 60°C.
• Carefully check the water temperature at the hot water taps before
holding your hands all the way into the water jet.
HINT! DAMAGE POSSIBLE
Damage to the air heat pump and components possible.
• Read and follow the operating instructions.
• In order to avoid accidents and damage to property, the safety
instructions must be observed!
• The national regulations of the country in which the ratiotherm WP
Max-Air air heat pump is used must be observed.
WARNING! DAMAGE POSSIBLE

2.5 INSTALLATION AND ADJUSTMENT
The installation, commissioning or dismantling of the device may
only be carried out by a specialist with specific knowledge which is
necessary for the activities with this device.
The existing regulations, rules and guidelines as well as the local
installation specifications must be observed.
BEWARE!
Safety valve and blow-off line
During the heating process, the water volume increases. For this
reason, never close the blow-off line of the safety valve.
Hot water can escape from the blow-off line!
Leakage
If there are leaks in the heat pump area, switch off the system and
close the connection to the rest of the heating system.This must then
be repaired immediately.
HINT!
Corrosion damage
To prevent corrosion on the device, do not use any sprays, solvents,
cleaning agents containing chlorine, paints, adhesives, etc. in the
vicinity of the device. These substances can lead to corrosion under
unfavourable circumstances.
