General Advice - Kroll PE90 Manual De Instrucciones

Before using the space heater, please read carefully all the instructions for use described below and follow the
indications scrupulously.
The manufacturer cannot be held responsible for damage to persons and/or property caused by improper use of
the equipment.
This instruction manual is an integral part of the equipment and must therefore be kept carefully and passed on
with the unit in the event of a change of ownership.
DESCRIPTION
The hot air generators is designed for heating medium and
large ventilated premises, for which a fixed or mobile heating
system is required.
Space heaters can be run on natural gas (G20, G25) or L.P.G.
(butane G30 and propane G31) according to different gas supply
pressures that must be in conformity with the national laws of the
European Community countries. Gases to be used in each
country of the Community are indicated in Tab. I together with
the supply pressures, the corresponding category (which
indicates the two previous pieces of information, i.e. the type of
gas and the supply pressure), the regulation of the gas valve
group and the arrangement of the diffusion ring (3).
Space heater is set up for one of the operating categories in
Tab. I: the adhesive label applied to the gas valve group (4)
indicates the operating category.
To convert to a different category and, therefore, to another
type of gas, follow the detailed instructions given in the section
"CHANGING TYPE OF GAS".
Space heaters are of the direct combustion type. The air is
heated by the thermal energy generated during combustion and
is then conveyed to the room to be heated with the products of
combustion: the room must in any case be suitably ventilated in
order to ensure adequate air circulation.
Various safety devices (electronic control unit, overheating
thermostat LI, air pressure switch, gas pressure switch) trip in the
event of serious malfunction.
The electronic burner control unit trips if the flame is irregular
or goes out or when the supply voltage drops too low (T < 195
V). The overheating thermostat LI trips when the temperature of
the combustion chamber exceeds the safety limit. The air
pressure switch and gas pressure switch trip respectively if the
air flow is insufficient or if the gas supply pressure is too low.
In each of the cases described above, the space heater stops
working and the reset button light (8) comes on (except in the
event of low gas pressure).
Working resumes automatically only if the cause has been low
gas pressure or low supply voltage, when the missing supply has
been restored.
In other cases working operation can only be resumed by
pressing the reset button (8) or (4), as described in the
paragraph "FAULTS, CAUSES AND REMEDIES".
Nonetheless, the cause that triggered the safety device should
always be sought and remedied before restarting the heater (see
"FAULTS, CAUSES AND REMEDIES").
Space heaters can be completed with a series of accessories:
a) clock timer or room
electromechanical device for automatic switching on and off
b) kit for remote control from a Personal Computer
c) kit for control from the remote panel (max distance 5 m),
useful for ceiling-mounted installations or in restricted
situations where access to the control panel is limited
d) kit for delayed heater switching on, useful for multiple
installations to prevent overloading the electrical power
supply.
e) anti-condensation kit, indispensable for installations under
very humid conditions (greenhouses, battery farming, etc.)
to solve the problem of ignition failure.

GENERAL ADVICE

Installation, setting up and use of the hot air generator must be
IMPORTANT
thermostat or a similar
EN
effected in accordance with the applicable regulations and laws
relating to the use of such equipment.
The space heater can be installed suspended from the ceiling
by means of cables and/or chains of suitable size and length to
fix to the 4 suspension hooks.
Warning
Make sure that the cables and/or chains form a
maximum angle of 5° off vertical on the ceiling.
The minimum distance from surrounding walls, floor and/or
ceiling must be at least 1 m and the distance from the floor of at
least 500 mm.
The minimum proximity of objects, property, persons and/or
animals to be kept in front of the air distribution area must be at
least 1,5 m, having checked that they can support the maximum
temperature, which can be found by adding the room
temperature + ∆T @ 1.5 m (as shown on the identification label
affixed to the space heater itself).
Make sure that:
• The instructions in this manual are carefully followed;
• The generator is not installed in an area where there is a
high risk of fire or explosions;
• No flammable materials are stored in the vicinity of the
heater (the minimum distance must be at least 3 m)
• A check is made that there is no overheating of walls,
ceilings or floors made of flammable materials
• All precautions have been taken to prevent fires;
• The premises in which the heater is installed are sufficiently
ventilated for the burner requirements; in particular the limits
regarding the quality of the air in the room to be heated
must be complied with, as prescribed by the applicable
national or local laws or, in the absence of any standards
and/or indications, in compliance with the provisions of N
12669:2003.
• The air suction and/or supply hoses are not blocked in any
way, there are not sheets or covers resting on the machine
or walls and bulky objects near the generator;
• The generator is placed near a power switchboard having
specifications that conform to those declared;
• The unit is placed in a fixed position;
• The heater is regularly monitored during operation and
checked before being started up;
• At the beginning of each working period, before plugging it
into the electrical power supply, a check is made that the
fan moves freely;
• At the end of each working period the main switch is
disengaged and the gas stopcock is closed.
Warning
This unit may not be used by persons (including
children) with reduced physical, sensorial or
mental capacities or with limited experience and
familiarity unless they are under supervision or
instructed on how to use the equipment by the
person responsible for its safety.
