DESCRIPTION
OF THE SYSTEM
3.1 The BMTB heat pump water heater (BMTB) consists of a Solar Assisted
heat pump, coupled with either a 32, 54 or 79 gallon capacity hot
water storage tank. The Solar Assisted Heat Pump is integral to and
positioned on top of the unit within the unit casing.
3.2 The BMTB is designed to heat the domestic hot water within the
tank up to 130OF.Themaximumtemperatureisinuencedbythe
individual installation, pipe lengths and insulation. It uses an exterior
aluminium panel (evaporator) to absorb energy from the ambient air.
A copper coil(condenser) is wrapped around the external wall of the
inner cylinder which heats the water inside the cylinder. The product
 hasareciprocatingcompressorforquietandefcientperformance.
With these features the BMTB is designed to have a long, trouble free
life.
3.3 The BMTB has integral safety devices to protect the product from
internal and external faults. An adjustable digital thermostat, locted at
the front of the BMTB controls the water temperature.
3.4 The BMTB is designed to store potable water supplied from the public
mains with a maximum of 200 p/m.
3.5 The BMTB has a built in timer which once a week heats the water in
the cylinder above 140OF to provide pasteurisation.
3.6 The BMTB is manufactured in the United Kingdom in an
 ISO9001:2000certiedfactoryandtestedtoEN16147,UL1995,CE,
CSA.
3.7 SAHP supplies an Installation Kit which contains items that will be
needed on the installation of the BMTB’s refrigeration circuit.

4.1 The BMTB must be installed on a stable base which must be capable
of supporting the weight when the cylinder is full of water.
4.2 Access for maintenance of all equipment should be considered when
positioning the vented / unvented cylinder. Care should be taken
that the immersion heater can be withdrawn for servicing if required
these are 15” long. Relevant local and national standards should
always be followed when installing discharge pipe work from the
safety valves.
4.3 We recommend that the hot and cold water requirements of the
property and user are ascertained before the installation of the BMTB
either unvented type or vented type.
4.4 The minimum incoming cold water mains inlet requirements for the
 BMTBis20psioperatingpressureand5USgalperminuteowrate.
4.5 Adjustable pressure reducing valve factory set at 43.5 psi is supplied
 withtheBMTBwhichmustbettedintheincomingcoldwatersupply
to the cylinder. The pressure reducing valve will deliver maximum of
13 US gal per minute.
4.6 Inhardwaterareaswerecommendthatawatertreatmentunitistted
to eliminate the formation of limescale in the system.
4.7 Do not install the equipment in the following places as they will lead
to a malfunction of the equipment: areas with corrosive gases,
 factorieswheretheelectricalvoltageexperienceswideuctuations,
 placeswithstrongelectromagneticwaves,placeswithinammable
materials or gases, other special environments.

4.9 Afullborecoldwaterisolatingvalvemustbettedinthecoldwater
 supplytotheBMTB.Thisvalveisnotsuppliedwiththettingkitofthe
unit.
4.10 It is good practice to position the mains inlet control manifold at the
top of the unvented unit to ensure that the cylinder does not have to
be drained down for the purpose of maintenance.
4.11 The expansion vessel can be mounted in any Orientation. Access
must be available to the top and bottom of the vessel. The vessel
 shouldbexedtoasolidwallusingthebracketsprovided.Please
remember that the vessel will get much heavier once it is full of water.
4.12 For mixer showers and taps a balanced cold feed at the same pressure
as the hot feed may be necessary. A 3/4” balanced connection on
the inlet manifold is provided for this purpose. Pipe work should
initially run in3/4” then this can be reduced where necessary.
4.13 We highly recommend installing a thermostatic mixing valve in system
where the set point temperature of either the heat pump or any heat
sources connected to the boiler coil are set to 120OF or above.
4.14 All exposed pipe work should be insulated and additional
considerations should be taken to protect the unit from frost damage.
Particular care is needed if the cylinder is to be installed in an exposed
location such as an out building or garage.
4.15 Beforellingandpressuringthecylindercareshouldbetakento
 checkandtightenallconnectionsincludingfactoryttedconnections
as they may work loose during transportation and positioning.
All of the pipe work connections on the cylinder are either 3/4”
compression or 3/4” copper tube should only be used to
connect to these connections. Good working practices should be
used when preparing pipe work such as using correct pipe cutters
and de-burring.
4.16 The boiler coil connections supplied are compression connections.
The boiler circuit must be positively pumped, gravity circulation will
not provide the required heat transfer through the coil.
