GENERAL CAUTIONS
This manual is an integral part of the product and must always
accompany it.
Should the equipment be sold or passed on to someone else,
always make sure that this manual is supplied with the equipment
for future reference by the new owner and/or installer.
The manufacturer shall not be held civilly or criminally responsible
for injuries to people or animals or damages to things caused
by incorrect installation, calibration and maintenance or by
failure to follow the instructions contained in this manual or by
operations carried out by unqualified staff.
This product must be used only for the applications for which
it was designed or approved. Any other use must be regarded
as hazardous.
During the installation, operation and maintenance of the
equipment described in this manual, the user must always
strictly follow the instructions given in all the chapters of this
use and instruction manual.
----------------------------------------------------------------------------------
The condensing warm air heater must be installed
in compliance with current regulations, according to
the manufacturer's instructions and by qualified staff,
technically specialised in the heating field.
----------------------------------------------------------------------------------
----------------------------------------------------------------------------------
ATTENTION: Due to the physics of the thermal
exchange and the intrinsic functioning of the PCH
modules, the surface temperatures of the exchanger,
as they depend on different factors such as the
installation of the module inside the AHU/Roof-top
unit and the dimensioning of the air distribution
ducts and/or terminals cannot be guaranteed by the
controls on board the PCH alone.
If the PCH modules are used in combination with
flammable or slightly flammable refrigerant gases
(A2L), precautions must be taken to ensure that
accidental refrigerant leaks do not lead to dangerous
situations.
In case of doubt, please contact the APEN GROUP
SPA technical office
----------------------------------------------------------------------------------
First start-up, conversion between different types of gas and
maintenance operations must be carried out only by suitably
qualified staff of
Technical Service Centres certified by current
and older standards
prevailing in the installation country and
in compliance with the issued authorisation.

SAFETY-RELATED WARNINGS
This chapter describes the safety instructions to be followed
by machine operators
2.1. Fuel
Before starting up the heater, make sure that:
•
gas supply specifications match those written on the
nameplate;
•
the combustion air intake ducts (when fitted) and the flue
gas pipes are only those specified by the manufacturer;
•
the combustion air is supplied in such a way as to avoid
even partial obstructions of the intake grille (caused by
leaves etc.);
•
the gas seal of the feeding system has been tested and
approved in compliance with the applicable standards;
•
the heater is supplied with the same type of fuel it has
been designed for;
•
the system is correctly sized for such flow rate and is
fitted with all safety and monitoring devices required by
applicable standards;
•
the inside of the gas pipes and air distribution ducts for
ducted heaters have been thoroughly cleaned;
•
the fuel flow rate is suitable for the power required by the
heater;
•
the fuel supply pressure is between the range specified
on the nameplate.
2.2. Gas Leaks
If you smell gas:
•
do not operate electrical switches, telephones or any other
object or device that could produce sparks;
•
immediately open doors and windows to create an air flow
to vent the gas out of the room;
•
close the gas valves;
•
call for
qualified staff.
-------------------------------------------------------------------------
NOTE: supplying the gas circuit with pressure greater
than 60 mbar is strictly prohibited.
Such pressures could cause the valve to break.
-------------------------------------------------------------------------
2.3. Power supply
The heater must be correctly connected to an effective earthing
system, made in compliance with current regulations (IEC 64-8).
Cautions
•
Check the efficiency of the earthing system and, if required,
call out a qualified engineer.
•
Check that the mains power supply is the same as the
power input stated on the equipment nameplate and in
this manual.
•
Do not mistake the neutral for the live wire.
•
The heater can be connected to the mains power supply
with a plug-socket only if the latter does not allow live and
neutral to be swapped.
•
The electrical system and, more specifically, the cable
section, must be suitable for the equipment maximum
power input, shown on the nameplate and in this manual.
