Sequence of functions
After the unit has been switched on
or in case heating is reqired (automatic function with room thermostat), the supply air fan also switched
on.
After the preliminary ventilation of
the burner, the solenoid valve opens
the fuel supply for the oil nozzle.
The fuel, sprayed under high pressure, is enriched with an amount of
oxygen that has been adapted to the
heating capacity and ignited using
an electrical, high-voltage ignition
spark.
As soon as a flame is burning without a problem, the automatic burner relay assume the optical flame
monitoring function.
After a short period of time, hot air
is blown out.
The automatic burner relay perform
all device functions fully automatically and monitor them securely.
In case of any irregularities or an
instable or extinguished flame, the
unit is deactivated by the automatic
burner relay.
The pilot lamp on the automatic
burner relay lights red.
A restart of the unit is only possible
after a manual reset of the automatic burner relay.
After the unit has been shut down
using the operating switch or by
the room thermostat, the supply air
fan continues to run for a certain
period of time to cool the combustion chamber and then shuts down
independently.
Concerning to each room temperature the thermostat operation
repeats the descripted operation
automatically.
When the unit is in use, the safety
guidelines of the employers‘ liability
insurance associations, the respective
country construction ordinances, and

Proper Use
Due to their conception and equipping, the devices are designed
solely for heating and ventilation
purposes in industrial or commercial use (no private living area
heating).
The unit may be operated only by
accordingly trained personnel.
The manufacturer is not liable for
damage that occurs due to nonobservance of manufacturer instructions or the legal requirements or
due to unauthorised changes to
the device.
Customer Service and
Guarantee
The prerequisite for any warranty
claims is that the customer or its
recipient has returned the completed „Warranty Document“ included in delivery to REMKO GmbH
& Co. KG at the time of the sale
and commissioning of the unit.
The unit wastested several times at
the factory for perfect function.
If any malfunctions should
occur, however, which cannot be
eliminated by trouble shooting
measures performed by the operator, please consult your dealer or
contract partner.
Environmental Protection and Recycling
Disposal of packaging
When disposing of the packaging
material, think of the environment.
Our equipment is carefully packed
for transport and delivered in a
stable cardboard transport package
on a wooden pallet, if necessary.
The packaging materials are
environmentally friendly and can
be reused.
With the reuse of packaging material, you make a valuable contribution to the reduction of waste and
the preservation of raw materials.
You should thus dispose of the
packaging material at the corresponding disposal sites.
NOTE
Another operation other than
that described in these operating instructions is not
permitted.
Nonobservance leads to the
extinguishment of any liability
and warranty claims.
NOTE
Adjustment and maintenance
tasks may be performed only
by authorised expert
personnel.
Disposal of the old device
The equipment manufacturing
process is subject to constant quality control.
Only high-quality materials that
are recyclable to a great extent are
used.
You also contribute to environmental protection by guaranteeing
that your old unit is disposed of an
environmentally friendly manner.
For this reason, bring the old unit
only to an authorised recycling
company or to a corresponding
disposal site.
