DESCRIPTION
Stainless Lite is a range of unvented hot water storage cylinders, manufactured in
the latest high quality duplex stainless steel. They are designed to provide mains
pressure hot water and are supplied as a package which complies with Section G3
of the Building Regulations. The appliance is extremely well insulated using high
density HCFC free foam insulation with an ozone depleting potential (ODP) of zero
and a global warming potential (GWP) of 1. It is fi tted with all necessary safety devices
and supplied with all the necessary control devices to make installation on site as
easy as possible.
Stainless Lite Heat Pump (HP) models:
The Stainless Lite HP is an unvented hot water storage cylinder fi tted with two high
effi ciency internal primary heat exchangers especially designed for use with heat
pump systems. These two heat exchangers can be connected in parallel to the heat
pump circuit when a solar thermal system is not installed. When both heat pump
and solar thermal systems are installed, the top heat exchanger is connected to the
heat pump circuit and the bottom heat exchanger is connected to the solar circuit
a shown in fi gure 2.
All Stainless Lite HP models are fi tted with 3kW (230Vac, 50Hz) immersion heater
for raising the temperature of the stored water to about 60°C after the heat pump
heating cycle if necessary. The technical details of the Stainless Lite HP models are
listed in table 1.
Important notes:
1. All Stainless Lite HP models are suitable for both open vented and sealed primary
systems.
2. When used with a sealed primary heating system, the heat pump must incorporate
its own over heat thermostat.
3. Stainless Lite HP models must not be used with solid fuel boilers or steam as the
heat source.
4. Heat pumps can normally only heat the domestic hot water to between 45 – 50°C,
therefore provision should be made to periodically heat the cylinder to about 65°C
to prevent growth of legionella.
5. The cold supply elbow c/w drain tapping must be fi tted as shown in fi gures 1 &
2. A fl exible hose can then be connected to the drain tapping and providing the
hose runs below the lowest level of the cylinder, then all the water content can be
drained out by the symphonic action.
