For the Installer
General
VPAS 300/450 is a series accumulator tanks/water
heaters, which is suitable for connection to heat pumps,
gas or oil-fired boilers.
The water heaters consist of a hot water tank and an
enclosing, double walled sheet steel jacket. The water
tank is lined with copper or enamel corrosion protection.
The water heater is designed and manufactured for a
maximum cut-off pressure of 10 bar. Maximum permit-
ted temperature is 90 °C.
Maximum working pressure in the double jacket is 2,5
bar.
VPAS 300/450 is equipped with a copper finned tube
of 2,3 m², for connection of up to 15 m² solar panel.
The insulation is Neopor and polyester fleece, which
provides excellent heat insulation. The insulation and
grey plastic outer cladding can be removed easily to
simplify moving the water heater through doorways, for
example.
VPAS 300/450 is equipped with two immersion heater
sockets and submerged tube for control of hot water
heating, radiator operation and solar coil.
Transport
VPAS 300/450 should be transported and stored vertic-
ally in a dry place. The VPAS 300/450 may, however, be
carefully laid on its back when being moved into a
building.
