2 LOCATION - GENERAL
2.11 Access: For emergencies and maintenance the pump must be
easily accessible.
2.12 Protection: The pump must be located in a dry position, frost free and
protected from freezing, particularly when installed in a loft (not
recommended).
2.13 Ventilation: Ensure an adequate air flow to cool the pump. Separate
the pump from other appliances that generate heat. An 80 mm (3 “) air
gap must be maintained around the pump.
2.14 Safety: The motor casing can become very hot under normal
operating conditions. Care must be taken to ensure it cannot be
touched during operation.
2.15 Water retention: Site the pump in a location where in the unlikely
event of a water leak, any spillage is contained or routed to avoid
electrics or areas sensitive to water damage.
2.16 Static inlet pressure: Before deciding where to locate the unit check to ensure
the static inlet head between pump and cold water level (Fig. 3) is at least
0.5 metre and does not exceed the max inlet head of 10 metres.
2.17 Pump position: The pump must be positioned on its anti-vibration mounting feet
and as close to the water source as possible.
2.18 Ambient temperature: The pump must be sited in a location where the maximum
ambient temperature does not exceed 40 o C.
2.19 Pipework: For optimum performance pipework MUST be 22 mm.
Pipework should only reduce to 15 mm when entering terminal fitting and pump
connections.
2.20
Static outlet pressure: The static outlet head (Fig. 3) must also be within the
maximum requirement of 10 metres.
2.21 Noise: The anti-vibration mounting feet and flexible hoses which are supplied
as standard, and a precaution to reduce noise transmission, however care must
be taken when mounting the pump that any noise is not amplified through loose
panels or pipework. Do not screw down the pump.
2.22 Direction of flow: Ensure the water inlet supply is
connected to the correct pump ports indicated by
INLET arrow/s detailed on the pump rating label
Fig. 2.
2.23 Flexible hoses: Use only the Techflow supplied hoses to connect the pump.
2.24 Inline strainer: When pump is to be installed in areas where there is risk of
debris or scale build up within the system, you MUST ensure the inlet pipework is
fitted with an inline strainer.
2.25 Preferred pump location: The preferred pump location is at floor level next to
the hot water cylinder or a level that is below the secondary tapping that feeds
the pump. Pump location is also dependent on limitations of the static inlet and
outlet heads of the installation. For guidance on limitations and recommended
location, consult the following relevant section for hot or cold water installation.
