1. FUNCTIONAL DESCRIPTION
The high-temperature heat pump WP Grid-HiQ CF06 is suitable for use in district heating networks with
varying temperatures in the range of 10 to 55 °C.
This flexibility is achieved by a patented process that enables the system to always reach the optimum
operating point despite a changing source temperature.
The maximum flow temperature is 72 °C.
The Grid-HiQ CF06 comprises an integrated 200 or 400 litre buffer storage tank including an expansion
tank and heating circuit, as well as a fresh water station together with a home controller. This means that a
complete heating room can be accommodated in one unit, allowing a quick and uncomplicated installation.
Supplemented by the optional integrated district heating transfer, it enables a variety of network strategies.
The Grid-HiQ is extended by numerous options and thus represents a complete package for district heating
technology.
BENEFITS
• usage of varying source temperatures from 10 to 55
°C possible
• highest flexibility thanks to speed-controlled inverter
operation
• passive and active cooling possible
• integrated district heating direct exchanger
• flow temperatures up to 72 °C possible
• integrated energy management (Smart-Grid capable)
• numerous network strategies possible
• easy installation thanks to complete pre-assembly in
the factory, no refrigeration certificate required
• with ratiotherm components a completely
coordinated, future-proof system

2. NOTES ONTHE DODUMENTATION
2.3 INTENDED USE
The ratiotherm heat pump WP Grid-HiQ CF06 is constructed according to the state of the art and the
certified safety regulations.
The heat pump is only intended for the preparation of hot water and the generation of heat and cold in
residential and / or non-residential buildings.
Incorrect or non-intended use could result in danger to life of the operator or a third party.
In addition impairments of the devices and other material assets can arise.
The ratiotherm heat pump WP Grid-HiQ CF06 is not intended for being used by individuals
(including children) with restricted physical, sensory or mental abilities.
The heat pump also can not be operated by individuals with a lack of experience and/or
knowledge.
• Unless they are supervised by an individual responsible for their safety or they received
instructions on how to use the device.
The ratiotherm heat pump WP Grid-HiQ CF06 is exclusively intended for the preparation of
hot water (process water) and the generation of heat and cold.
Any other or futher use is considered improper. The manufacturer/supplier is not liable for
damage caused by improper use.
The operator is responsible for the risks.

• The outflow temperatures at the hot water extraction points might be
up to 60 °C.
• Carefully check the water temperature at the hot water extraction
points before placing your hands under the water jet.
NOTE! DAMAGES POSSIBLE
Damages of the heat pump and components possible.
• Read and follow the instructions.
• To avoid accidents and material damage observe the safety
instructions.
• Observe the national rules of the country in which the ratiotherm heat
pump WP Grid-HiQ CF06 is used.
WARNING! DAMAGES POSSIBLE
Do not make any changes:
• to the heat pump;
• to the water pipes and the power lines;

5. HYDRAULIC INSTALLATION
5.4 INSTALLATION GUIDE
For this purpose please disconnect the:
• 4 hose connections (barriers are provided in
each case),
• electrical connections to the housing (6 plug
connections),
• sensor S5, • 2 screw connections in the base plate,
• electrical connection to the district heating valve (watch out for the detent of the plug).
The machine is delivered on a pallet in two parts:
• storage module (200 litres of buffer storage including
FriWa and 24 litres MAG)
• hydraulic module + cooling unit
For easier transport, the refrigeration unit (approx. 80 kg) can
be removed from the hydraulic module.
