Step 1: Pump location
1. Site the pump in a location where it will not freeze or be exposed to frost during cold weather.
2. Ensure adequate airflow to cool the motor. Separate the pump from other appliances that
generate heat. Install the pump in a clear space allowing 100mm at each side, end and top.
3. Do not endanger pre-existing electrics when siting your Salamander pump
4. Ensure the pump is as close to the hot water cylinder as possible and no more than 5m in
measured pipework away.
5. Mount the pump upright (shaft horizontal, not screwed down).
6. Where the pump is located above the hot water cylinder, it must be a minimum of 600mm below
the cold water cistern. The best connection is a side entry cylinder connection in 22mm with an
Anti-Gravity Loop (AGL) of 400mm (Figure 2), Alternatively, a top entry flange may be used, but
the pump cannot be teed from existing feeds where it is located above the hot water cylinder. If
aeration causes an issue, it may become a requirement to use an Essex Flange.
7. Bathroom Zones: Salamander products covered in these notes cannot be installed
in Zone 0 or Zone 1. They can however be installed in areas that are accessible with
a tool. (See Figure 3).
The pump should be installed in accordance with BS7671:2018.
In BS7671:2018 rooms containing baths or showers should be broken down into zones.
These zones are summarised as:
ZONE 0 – This is the bath or shower tray.
ZONE 1 – Is considered to be the area where the individual is bathing or showering
or the area where shower water is likely to be directly sprayed.
ZONE 2 – Is the area beyond Zone 1, extending by a further 600mm.
Please refer to BS7671:2018 for further guidance.
