For the Installer

General
VPA 450/300 is a series water heater, 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 for copper and 3 bar for enamel.
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.
VPA 450/300 is equipped with two immersion heater
sockets and submerged tube for control of hot water
heating.
Transport
VPA 450/300 should be transported and stored vertically
in a dry place. The VPA 450/300 may, however, be care-
fully laid on its back when being moved into a building.
Assembly
The water heater is only designed for upright installation.
The water heater is unscrewed from the pallet and lifted
into position, using the lifting eye at the top.
The top insulation must be removed to access the lifting
eyes on VPA 450/300 E.
Position VPA 450/300 on a firm base that can take the
weight, preferably on a concrete floor or foundation.
Use the product's adjustable feet to obtain a horizontal
and stable set-up.
The area where VPA 450/300 is located must be
equipped with floor drainage.
