Nibe EKS 500 Installation And Maintenance Instructions Manual page 6

General
The water heater consists of a steel vessel, with a cop-
per lining to protect against corrosion.
The heater is designed and manufactured for a maxi-
mum cut-off pressure of 9 bar.
Maximum permitted temperature is 95°C.
The EKS 500 is insulated with 50 mm thick poly-
urethane. The insulation can be removed to make it
easier for the heater to pass through doorways, for
example.
The outer shell is grey plastic.
The water heater is equipped with a lifting eye.
The EKS 500 can be equipped with up to two immer-
sion heaters. The connection diameter is G50 and the
maximum immersion heater length is 650 mm.
The enclosed kit contains cover discs and a drain valve.
Removing the insulation
The insulation on EKS 500 can be removed, to facilitate
work in confined spaces (the heater's diameter without
insulation is 670 mm).
1. Remove all screws along the joining plates.
2. Remove the lifting eye at the top by unscrewing it
anticlockwise.
3. Lift off the top cover.
4. 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 joining plate can be
turned upside down, which produces new holes in the
insulated jacket halves.
