WATER TREATMENT PRODUCTS
Suitable water treatment products can be obtained from the following
manufacturers:
ARTIFICIALLY SOFTENED WATER
It is possible to have an ion exchange water softener fitted to the cold
water system of the property. However, the boiler requires an untreated
cold water connection taken from the mains supply, before the water
softener, to the primary water filling point of the heating system.
Alternatively there are water softening/treatment devices that do not
adjust or alter the pH levels of the water. With these devices it may not
be necessary to provide an untreated water by-pass to the primary water
filling point of the heat system.
5.2 SYSTEM COMPONENT CONFIGURATION
5.2.1 GENERAL REQUIREMENTS
• The permissible maximum length of the refrigerant lines between the
external unit and the hybrid manager is 30 m with up to 15 bends
(single direction).
• The permissible minimum length of the refrigerant lines between the
external unit and the hybrid manager is 1 m in a single direction.
• A height differential between the installation site and the hybrid
manager is permissible. However, take the maximum pipe length of
30 m into account.
• If the hybrid manager is mounted above the heat source, fit an
automatic air vent valve at the highest point of the heating system.
• The maximum equivalent length of pipe work with which the hybrid
manager is connected to the existing heating system flow and return
should be determined from tables 50 and 51. One metre must be
subtracted for each 90° bend.
• Rooms where the hybrid manager or the refrigerant lines are installed
must have a volume of at least 5.7 m³, if the room can be occupied.
5.2.2 BUFFER TANK
The buffer tank must be installed in series in the flow between the hybrid
manager and the system by-pass.
5.2.3 BYPASS VALVE
The bypass valve is connected between the flow out from the buffer
vessel and the first radiator on the heating system.
Further requirements of the installation site:
• The bypass valve must be fitted into a straight pipe section and not
immediately near a bend.
• For commissioning and maintenance the bypass valve must be easily
accessible.
• Fit the bypass valve as near as possible to the heating system and as
far away as possible from the buffer vessel.
5.2.4 EXPANSION VESSEL
Install an additional expansion vessel on the heating system return
between the bypass valve and the hybrid manager. Size the expansion
vessel according to EN128-28.
5.2.5 THERMOSTATIC RADIATOR VALVES
For optimum comfort and system efficiency a thermostatic radiator
valve should be fitted to each radiator within the circuit, except for the
radiator in the same room as the room controller.
5.2.6 HYBRID MANAGER
Information on the installation site:
• Ensure minimum clearances are maintained.
• Mount the hybrid manager on to a fixed rigid wall capable of
supporting the weight of the unit.
• To reduce the installation effort we recommend the installation of the
hybrid manager below the heat source ( Fig. 7, page 9).
• Flow and return pipes can be routed vertically from the top or bottom
into the hybrid manager.
• Refrigerant lines can be routed vertically from the top into the hybrid
manager.
• If refrigerant lines are to be routed downwards, allow for adequate
space to route the pipes downwards alongside the unit, preferably on
the left hand side.
MINIMUM CLEARANCES

Table 5
The following requirements must be met. The following
sections detail additional requirements for the
installation of the individual system components.
It is important the pump speed is set correctly, please set
the HE pump inside the hybrid manager
( chapter 6.2.9, page 35).
NOTICE:
▶ Please refer to the Buffer tank installation instructions
for correct hydraulic connection.
WARNING: Rooms where the hybrid manager or the
refrigerant lines are installed must have an internal
volume of at least 5.7 m3, if the room can be occupied.
Dimensions given are minimum clearances around the
Hybrid manager for the purposes of installation and
service.
The minimum volumetric requirements of the room size
must also be adhered to according to EN: 14511.
DANGER:
▶ Never site the external unit in locations where
flammable gases could be released, accumulate or
flow past.
