Planning your Installation

Twin-ended
Shower Booster Pump
DURASPEED, VARISPEED 50, DURASPEED 2
& SINGLESPEED (Fig. 1.)
Twin booster pumps are best installed in the airing cupboard with separate hot and
cold water supplies running to the pump. For correct operation of the shower
pumps both hot and cold water supplies to the unit must be gravity fed, at
nominally equal pressures; cold water from a cold water storage tank and hot water
from a hot water storage cylinder fed from a cold water storage tank.
Single-ended
Shower Booster Pump
VARISPEED SI (Fig. 2.)
Single Booster pumps are best installed after the mixing valve with blended hot
and cold water running to the pump and then onto the handset position. With a
recessed installation, the outlet from the mixer valve can be fed to the inlet of the
single ended pump, and the pump outlet connected to the shower hose, normally
via a shower hose union elbow. See page 4 for gravity hot water boost only.

Plumbing

• We recommend a minimum 115 litres (25 gallon) cold water storage tank, but
please ensure compliance with all water by-laws.
• Under no circumstances must the pump be connected to the mains cold
water supply.
• Do not use jointing compounds
• Before proceeding with the installation of this unit, it is essential to check that
the handset and all pipework will be a minimum of 230mm (9") below the water
level in the cold water storage tank.
• If your installation does not allow this, you will require a negative head switch.
Contact your supplier or NewTeam Customer Services. If you have not sourced
your negative head switch from NewTeam, please contact NewTeam Customer
Service for a connection block. Please refer to page 9 for details of negative
head installation.
• Please ensure that the shower pump and mixing valve are not positioned
in areas subjected to freezing conditions.
