Fitting your Pump
5
NEWTEAM SHOWER PUMPS
Important:
Please be aware of the following when planning your installation :
• All plumbing should be completed before any electrical connections are
undertaken.
• The pump must be positioned in a dry area i.e. in a linen/airing cupboard, as close
to the base of the hot cylinder as possible, ideally pushing water not pulling. The
pump will work most efficiently when fitted close to the hot water cylinder.
•
The pump must not be mounted in a loft, as this leaves it vulnerable to
freezing, and air locks.
• The pump should be in a well-ventilated position and not covered with towels,
clothes, etc., and accessible for future servicing/maintenance.
• The pump can be connected to a combination cylinder system providing it
has a cold water storage capacity of 115 litres.
• When connecting pipework avoid using elbows. Sweep or formed bends will
ensure optimum performance.
• Do not solder within 300mm of the pump, or expose parts to excessive heat.
• Do not run pump dry.
• The minimum inlet size is 15mm for all pipework to and from the pump.
• Non restrictive full bore isolating valves (accessible for ease of maintenance on hot
and cold supplies to the pump) must be fitted e.g gate valve.
• In normal circumstances the temperature of stored water must not exceed
65˚C. A stored water temperature of 60˚C is considered sufficient to meet all
normal requirements and will minimise limescale in hard water areas.
IMPORTANT THE BOOSTER PUMP AND ALL CONNECTING PIPEWORK
MUST BE EARTHED.
Installation Procedure:
IMPORTANT:
Do not connect brass or copper fittings directly on to the pump threads. Use only the
hoses supplied with the pump.
1. Isolate appropriate water and electrical supplies.
For the benefit of the user and
for any future servicing please fit full bore isolating valves 1/2 metre from the
pump on the inlet pipework.
2. Make your connection into the hot water supply pipe from the cylinder,
ensuring that it is in the vertical pipe (below the expansion pipe tee).
A minimum of 1 metre below the base of the cold water storage tank and the
top of the hot water cylinder must be achieved. (See Fig.1. for typical pump
installation)
3. If this is not possible, a direct connection must be made from the hot water
cylinder with an Essex Flange with dip tube. (See Fig.4)
4.
TWIN PUMPS ONLY:
The cold water supply should be taken directly from the
cold storage tank, and must be positioned 60mm below the cold feed connection
to the hot water cylinder. (See Fig.1. for a typical twin pump installation)
