Nibe VPB 500 Installation And Maintenance Instructions Manual page 9

General
VPB is a series of water heaters, which are suitable for
connection to heat pumps, gas or oil-fired boilers.
The water tank consists of a steel jacket, with a copper
lining to protect against corrosion. The water heater is
equipped with a copper coil of finned tube (two finned
tubes VPB 1000).
The water heater is designed and manufactured for a
maximum cut-off pressure of 10 bar. Maximum permit-
ted temperature is 95 °C.
The insulation is polyurethane, which provides excellent
heat insulation. The insulation and outer shell of grey
plastic is easy to remove. On VPB 750/1000, the top
insulation must be removed to provide access to the lift-
ing eyes.
The VPB is equipped with a immersion heater connec-
tion and an submerge tube for control of water heating.
Removing the insulation
The insulation on VPB can be removed in order to facili-
tate handling in confined spaces (the heater's diameter
without insulation is Ø 650/770/870 mm).
1. Remove all screws along the joining plates.
2. Lift off the top cover.
3. Pull the insulated jacket halves straight off.
Carry out assembly in reverse order. If the screws are
difficult to fit in the old holes, the plate can be turned
upside down, which produces new holes in the insu-
lated jacket halves.

Installation
The hot water heater is unscrewed from the pallet and
lifted into position, use the lifting eyes if necessary. The
water heater must be installed in an upright position.
The four feet are height-adjustable. VPB 500, 750, 1000
can be equipped with the following immersion heaters,
connection dimension G2. When installing the water
heater, ensure that there is enough room for removing
the immersion heater in front of the connection area,
see following table.
Fit the supplied cover discs before pipe installation. The
cover discs, with self-adhesive backs, must be fitted on
the relevant connection by pushing them over the con-
nections.
All connections (including those not used) must be insu-
lated to minimise idle losses.
