Instructions VX Solo II

2.0 Safety notes

Instructions

This operating manual should be read carefully before installation and

start-up of the substation. The manufacturer accepts no liability for

damage or faults that result from non-compliance with the operating

manual.

Please read and follow all the instructions carefully to prevent acci-

dents, injury and damage to property. The risk of persons being injured

The substation is designed for district heating as the primary source

of energy. However, also other energy sources can be used where the

operating conditions allow it and always are comparable to district

heating.

Application

The substation is designed only to operate with water or a water-glycol

mixture (up to 40%), and other heating media may not be used.

Connect the substation to the house installation in a frost-free room,

where the temperature does not exceed 50 °C and the humidity does

not exceed 80%. Do not cover or wall up the substation or in any other

are exceeded.

Safety valve(s)

We recommend mounting of safety valve(s), however, always in com-

pliance with local regulations.

Sound level.

≤ 55 dB.

Connection

The substation must be equipped with features that ensure that

the substation can be separated from all energy sources (also

The stations work at a maximum supply temperature from the

district heating network of 110°C and the stations work with a op-

erating pressure of 16 bar, which may put the user at risk of burns

from touching the surface or from the emissions of hot media

(water/steam). The risk of persons being injured and equipment

damaged increases considerably if the recommended permissible

operating parameters are exceeded.

Emergency

In case of danger or accidents - fire, leaks or other dangerous cir-

cumstances - interrupt all energy sources to the station if possible,

tion has not been damaged during transport. Always transport

the substation with the utmost care and caution.

IMPORTANT - Tightening of connections

Due to vibrations during transport all flange connections, screw

joints and electrical clamp and screw connections must be check-

ed and tightened before water is added to the system.

After water has been added to the system and the system has

been put into operation, re-tighten ALL connections.

(Do not overstrain! - See item 7.2)

3.0 Storage and Handling

should be carried out on pallets.

During and after unpacking, the substation can be lifted by using

straps, fitted around the pipes or it can be lifted by hand in the

pipes Lifting in the pipes can cause leaks. ALWAYS re-tighten.

Handling

When working on the substation suitable safety shoes must be

worn.

4.0 Disposal

Dispose of packaging material in accordance with local regulations.

This product consists of materials, which must not be disposed of
