ᘐ WARNING: The product contains the hydrocarbon
refrigerant R290 which is very ammable. The refrigerant
may mix with air to form a ammable atmosphere
increasing the risk of re and/or explosion. Work that
requires the removal of the exterior casing of the Heat
Pump must only be carried out by competent persons
who are familiar with the risks of R290 refrigerant. Work
on the refrigeration circuit must only be carried out by
a Cat I or Cat II F-gas certied engineer with a City and
Guilds 6187-21 certicate or equivalent. Work done on the
heat pump should be done in accordance with industry
standard safety procedures and practices for working with
hydrocarbons
ᘐ WARNING: Work on electrical systems must only be
carried out by competent persons.
ᘐ WARNING: The DHW Cylinder must be installed by a
competent person as dened by the relevant regulations.
Manufacturers notes must NOT be taken as over-riding
statutory obligations.
1.3.3 Appliance Symbols
These warning labels also include rules of conduct for the R290
refrigerant. The warning labels must not be removed.

1.3.4 Intended Use
and must be obeyed.
ᘐ WARNING: Failure to comply with the requirements
stipulated within this documentation may result in
increased risk of death, serious injury and/or damage to
equipment and property.
The Heat Pump is an air-to-water monobloc heat pump to be
installed in a domestic household with a sealed heating system.
The Ideal HP290 setup parameters do not provide a cooling
function.
The Heat Pump takes heat from ambient outdoor air for transfer
into domestic hot water or a space heating system. This air is
back into the natural environment.
The DHW cylinder is used to heat a store of domestic hot
water. The DHW cylinder is to be installed within a domestic
household.
The control box / heat pump controller is to be installed
as this contains the control system and installer interfaces
needed for the initial setup and commissioning of the overall
heating system. A limited interface is provided for the end user
however it is envisaged that day to day interface will be via a
Programmable Room Thermostat (PRT) i.e.,Halo Lite RF.
If the Halo Lite RF is not installed as the Programmable Room
Thermostat (PRT) and an alternative PRT is used it must have a
maximum cycle rate of 1 per hour.
The following basic functionality is recommended:
• Setback Temperature with a maximum 3°C below comfort
temperature.
• Heating Schedule with a minimum 2.5-hour optimisation.
System schematic diagrams in this document are meant for
reference only. It is the responsibility of the installer to make
sure that all appropriate measures are implemented.
The installation must comply with all accompanying
documentation and applicable local regulations and guidelines.
1.4 REGULATIONS
Installations must conform with the regulations of the installation site:
• National building regulations.
• Local regulations and provisions of local electricity suppliers.
• IET Wiring regulations.
•
