e, Regulations for the Use of Control and Adjustment Devices
On principle, there are 4 parameters to be observed for the control of a heat battery made by VOLTA:
- quantity of air;
- air intake or air exhaust temperature;
- operating voltage or current resulting thereof;
- use of operating groups (performence distribution).
If the air exhaust temperature is required to be changed or if the air intake temperature changes a control
can be achieved by switching on or switching off one or more operating groups without changing the
quantity of the air. If the quantity of air changes (to less than approx. 70-80 per cent of the quantity of air
defined for each heat battery embodiment) this may be balanced only by a voltage control (less current
required). For technical reasons the switching off of one or more operating groups will not lead to success.
If these instructions recommended by the manufacturer are not complied with this may result in a partly or
completely destruction of an air heating battery.
f, Operating Conditions
Air heating batteries are single piece productions which are produced for special customer operating
conditions and in accordance with the dimensions provided and requested for by our customer. On
delivery of the air heating batteries a complete documentation (Operating Instructions, Declaration of
Conformity, Technical Data Sheet, Table of Dimensions, Wiring or Circuit Diagram, Operating Instructions
for Thermostats used) is provided, the dates and operating instructions of which apply exclusively to this
individual air heating battery provided. The data included in the Technical Data Sheet are to be considered
as nominal operating values applying to the air heating battery specified by the customer and
manufactured in accordance with the requirements requested for by the customer. They must be complied
with to ensure an application of the air heating battery as directed.
It is also possible to manufacture air heating batteries in accordance with different operating conditions
which are considered on the occasion of its development and design and included in the Technical Data
Sheet. Any deviations from these recommended data provided must be compensated by suitable control
and adjustment actions to be carried out on-site. In unfavourable cases partial considerations of or
deviations from the values prescribed by the manufacturer (Technical Data Sheet refers) may cause
damage to or destruction of the air heating battery.
Unless otherwise specified in the Documentation of the Air Heating Battery normal environmental
and operating conditions, normal methods and modes of operation in accordance with Standard
DIN VDE 0100 are a prerequisite for the use and operation of the Air Heating Battery.
g, Repair Activities
VOLTA are able to supply replacement heating rods within a few days if the manufacturer's identification
number of the heating battery is advised by the customer. Then a qualified electrician will be able to
perform the required repair himself. Repair or maintenance activities may be performed only if all electrical
devices have been switched off, and the current supply system must be protected against re-switching in.
Furthermore it must be paid attention to the fact that the heating rods are cooled off sufficiently prior to
beginning with any repair and maintenance activities.
All repair activities may be performed by a corresponding expert only who installs and connects
replacement heating rods the same way he has removed the damaged heating rods prior to repair
activities involved. If larger heating batteries are subject to repair activities and to the extent that no
experts are available, it is advisable to have the repair work performed by the manufacturer. A heating
battery sent in for repair purposes will be returned in a few days as good as new and tested in accordance
with the regulations and/or specifications.
h, Long-Term Control and Maintenance
As a matter of principle it is not required to maintain air heating batteries. It will be sufficient to examine
the connecting cables periodically to ensure that the screws at the terminals are still tight and that both
earthing systems (connection and housing) are still operating properly and that the insulation of the cables
has not been cracked. Cleaning activities are required to be part of the maintenance activities only if the
medium to be heated is extremenly dirty or dusty (e.g. wood dust produced in a joiner's shop). It is
recommended to clean the heating rods with the help of compressed air.
