the heat pump. Check that the air purge valve can operate.
•
Take care that the components installed in the pipework can
withstand the water pressure.
3.6.3 system connections
The system connections of the heat pump must be carried out using
the flexible hoses, valves and fittings supplied with the heat pump.
The hydraulic circuit must be completed following the
recommendations below:
1. It is important to install the isolation valves between the heat
pump and the building.
2. The system must have drain cocks in the lowest points.
3. Air vents must be included at the highest points of the system.
4. A system pressure gauge must be installed upstream of the
heat pump.
5. All pipework must be adequately insulated and supported.
6. The presence of solid particles in the water can obstruct the
heat exchanger. Therefore, protect the heat exchanger using a
magnetic filter such as a Grant Mag-One.
7. After system assembly flush and clean the whole system,
paying particular attention to the state of the filter.
8. A new installation must be thoroughly flushed and cleaned
before filling and adding anti-freeze/biocide/inhibitor.
Do not use the heat pump to treat industrial process water,
swimming pool water or domestic drinking water. Install an
intermediate heat exchanger for all of the above cases.

3.6.4 remote controller
For details on how to install the remote controller, refer to Section 7.
For setting, refer to Section 9.
3.7 metering for Domestic rHI Installations
The current OFGEM requirements for the metering of ASHP
installations for the domestic RHI involve both ‘metering for
payment’ and ‘metering for performance’.
3.7.1 metering for payment (heat meter)
Many domestic ASHP installations will not be required to be
metered for payment, i.e. will not require a heat meter to be fitted.
The RHI payment will be based on the EPC annual heat pump
demand for the property concerned.
Even if an ASHP installation is not required to be metered for
payment, it must be ‘meter ready’ in accordance with MCS
requirements. Refer to the MCS Domestic RHI Metering Guidance
document for full details.
However, some domestic installations must be metered for
payment if:
a) The property is occupied for less than 183 days per year, e.g.
a second home or holiday home.
b) If there is a ‘back-up’ heating system installed, e.g. a fossil fuel
appliance is used alongside the ASHP (such as with a hybrid
system).
In the case of ‘self build’ (or ‘custom build’) homes, if the
homeowners move into the property before the system is
commissioned and have not lived in the property for a minimum
of 183 days, the installation will either have to be metered for
payment or they must wait at least 183 days before applying for the
RHI.
A heat meter must be installed and regular meter readings will
have to be submitted as the RHI payment will be determined from
these readings.
3.5.3 condense Disposal
The underside of the heat pump has a condensate outlet (refer to
Figure 3-3) that allows any condensate to drain from the heat pump.
Provision must be made to safely collect and dispose of the
condensate.
For example, use 40 mm waste pipe to form a condensate disposal
system into which the condensate flows from the opening in the
bottom of the heat pump casing running to a suitable gulley or
soakaway.
It is essential that the condensate is able to drain away and not
allowed to run onto any adjacent paths or driveways where, in
winter, this will result in icing and a potential hazard for any-
one walking near the heat pump.
the top of the concrete base must be either level with, or
above, the surrounding ground level.

3.5.4 Vibration
If the vibration from the heat pump is likely to cause a nuisance, use
the anti-vibration mounts (product code: HPIDFOOT/KIT2) and fix
the heat pump securely to the mounts.
3.6 Installing the Heat Pump
3.6.1 Insulation
The complete water circuit, including all pipework, must be
insulated to prevent heat loss reducing the efficiency of the heat
pump and also to prevent damage due to frozen pipes.
3.6.2 connecting the Heating system to the Heat Pump
•
Water connections must be made in accordance with diagram
in this manual and the labels on the heat pump.
•
Be careful not to deform the heat pump pipework by using
excessive force when connecting.
•
Pipework should be flushed before connecting the heat pump.
•
Hold the pipe end downwards when removing burrs.
•
Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.
•
the heat pump is only to be used in a sealed heating
system. It must not be used as part of an open-vented
system.
Before continuing the installation of the heat pump, check the
following points:
•
The maximum system water pressure is 3 bar.
•
Make sure the hose is connected to the pressure relief valve to
avoid any water coming into contact with electrical parts.
•
Air vents must be provided at all high points of the system. The
vents should be located at points which are easily accessible
for servicing. An automatic air purge valve is provided inside
