1 USER INSTRUCTIONS
1.1 Intended Use
The Warmflow Air Source Heat Pump units are intended for the production of hot water for space
heating and sanitary water. The units can be used to provide heating and domestic hot water
(DHW) via underfloor heating circuits, radiators and approved hot water cylinders. The units are
designed to extract heat from the air.
1.2 Compliances
The Warmflow AS01-R32, AS02-R32 and AS03-R32 air source heat pump units are
Microgeneration Certification Scheme (MCS) approved and hold both UKCA and CE markings.
They are approved on the Renewable Heat Incentive Eligibility list and can be found on both the
Product Characteristics Database (PCDB) as well as the Home-heating Appliance Register of
Performance (HARP) database. As such the units comply with the following directives and are
tested to the following standards:
MCS 007 Issue 3.0 - Product Certification Scheme Requirements: Heat Pumps.
2006/95/EC - Low Voltage Directive.
2004/108/EC - Electromagnetic Compatibility Directive.
97/23/EC - Pressure Equipment Directive.
EN14511 - Air conditioners, liquid chilling packages and heat pumps with electrically
driven compressors for space heating and cooling.
EN14825 - Air conditioners, liquid chilling packages and heat pumps, with electrically
driven compressors, for space heating and cooling. Testing and rating at part load
conditions and calculation of seasonal performance.
EN 60335-1 - Household and similar electrical appliances. Safety. General requirements.
EN 60335-2-40 - Household and similar electrical appliances. Safety. Particular
requirements for electrical heat pumps, air-conditioners and dehumidifiers.
EN 61000 - Electromagnetic compatibility (EMC). Limits.
EN 378 - Refrigerating systems and heat pumps. Safety and environmental
requirements.
ENV 12102 - Air conditioners, liquid chilling packages, heat pumps and dehumidifiers
with electrically driven compressors for space heating and cooling. Measurement of
airborne noise. Determination of the sound power level.
1.3 Basic Operation
Heat flows from an area of higher temperature to an area of lower temperature. In much the
same way that a water pump, pumps water from a low level to a higher level, a heat pump pumps
heat from a source at a low temperature to a source at a higher temperature. The benefit of this
is that natural sources such as the air and ground, which are at relatively low temperatures, can
be used to heat buildings at a higher temperature. In order to do this the heat pump uses a
relatively small amount of electrical energy. The proportion of electrical energy used to do this is
much smaller than the heat power delivered to the building. The ratio of the heat power delivered
to the electrical energy used determines the efficiency of the heat pump and is commonly known
as the coefficient of performance (COP).
Page 4
Heat is extracted from the air by blowing air through a finned radiator, known as the evaporator,
with a fan. The extracted energy from the air is transferred into the refrigerant which circulates
around the evaporator. The heat pump then converts this low grade heat to a high grade by
compressing the refrigerant using the compressor. The compression of the refrigerant increases
the pressure and the temperature. This high grade heat is then transferred to the heating system
via another heat exchanger known as the condenser. The heat can now be used to provide space
heating and DHW. The pressure of the refrigerant is then released through a throttling valve
known as the expansion valve which also causes the temperature to drop and allows the cycle to
start over again.

1.4.1 Starting Current
The AS01-R32, AS02-R32 and AS03-R32 air source heat pump units are all inverter driven. This
means they ramp up slowly and therefore do not require a large starting current which is required
with fixed speed units. In the majority of situations the starting current will be less than 1Amp.
The starting current will also always be below the rated current of the unit. Below is the typical
starting profile showing the compressor frequency (left side scale) and current draw (right side
scale) from off to typical running speed.
Figure 1 Starting Current

1.5 Construction
The Warmflow air source heat pumps are housed in a powder-coated galvanised metal casing
complete with enclosure box in which a cable entry terminal is mounted.
Figure 2 Typical Construction
Upon delivery, it is important that the unit is unpacked carefully and checked for any sign of
damage. If something is missing or damaged please report it to Warmflow immediately. The
units are secured to the shipping pallet using screws which must be removed.
NOTE: For coastal areas or other areas subjected to higher levels of corrosion, units can
be supplied with a Blygold coating applied to the evaporator to help protect it. Please
contact Warmflow for more details.
1.6 Supplied Components

1.7 Storage / Transport
The units come on a pallet (Dimensions of shipping sizes are shown below) and are secured to
the pallet using screws. If the units are to be stored prior to installation, they must be kept indoors
in storage conditions at a temperature of between 5°C and 60°C with a humidity level between
10%RH and 80%RH in order to provide a non-condensing environment. The units must not be
stacked in storage or during transport. During transport the units must be kept in an upright
position and should never be allowed to tilt more than 45° during loading or unloading.
