Pipe connections

General

The pipe installation must be carried out in accor-

dance with applicable standards.

A circulation pump must be used to ensure the flow

over the immersion heater. If the heating system

valves can close the circulation completely, the by-

pass valve must be installed so that the flow through

the electric heater does not stop. In closed installa-

tions an approved safety valve and pressure expan-

sion vessel must be used.

CAUTION

Also see the installer manual for your heat pump/in-

door module.

NOTE

The pipe work must be flushed before the electric

heater is connected, so that any contaminants do not

damage the component parts.

Draining

The system is most easily drained by installing a

drainage valve at the lowest point on the pipe instal-

lation. The remaining water in ELK 9M is drained

through the return line connection (XL2), see "Com-

ponent location" on page 5. If the return line connec-

tion on ELK 9M is normally used for draining the unit,

a drain valve can be installed here.
