1. INTRODUCTION
The company PROTON GROUP LLC thanks you for choosing
air heaters PROTON.
This manual is an integral part of the product and must
always accompany it, and should be transferred to the user.
To provide proper wiring and application of the unit, please,
study this manual thoroughly before installation.
We recommend keeping the manual safe in order to address
it during operation.
The user should strictly follow safety instructions while
installing, using and servicing the unit.
The access to the unit must be restricted for unauthorized
and unqualified personnel. The appropriate training of the
maintenance sta should be provided.
The manufacturer disclaims any responsibility for damages
caused by wrong installation and misuse of the unit.
The manufacturer disclaims any responsibility for damages
done by people who didn’t study the manual.
The manufacturer preserves the right to introduce any
amendments to the manual without prior notification.
The manufacturer preserves the right to alter the
construction which doesn’t impact its functioning and basic
technical parameters.
The air heater is intended only and exclusively to be installed
and used for purposes which it has been designed. Any
misuse or noncompliance with the manufacturer’s
instructions may lead to property damages, personnel injuries
or death. The user has to take measures to eliminate
possibilities of misuse of the unit.

2. SAFETY PRECAUTIONS
Before any actions connected with the air heater, please, study
this manual to provide safety.
Installation and connection of the equipment to pipelines and
networks must be performed by qualified personnel only,
having appropriate access.
During installation, start-up, repair and maintenance of the
air heater follow the safety rules.
Install the unit on a firm base or surface, which can stand its
weight filled with water.
Use screws appropriate for the material which the base is
made of.
Check correctness of connections of the system, accordance
of the heat medium parameters to the parameters indicated
on the rating plate as well as leak proof of joints before filling
in the heat medium.
Avoid substances and impurities in the heat medium causing
copper corrosion.
Check compliance of parameters of the electrical supply
network to the ones indicated on the unit’s rating plate
before connecting to the power supply.
Check grounding. Prohibit the use of the unit without
grounding as it may cause property damages, personnel
injuries and death.
Current network which feeds the unit’s motor and controls
must be additionally protected by a fuse to prevent
consequences of shunt fault.
Thermal protection of fan’s motor is built-in and works in a
standalone mode.
While the air heater is operating under low temperatures, the
-t
user must provide protection of the water heat exchanger or
use heat medium with special additives preventing copper
corrosion.
To prevent defrosting of the air heater’s heat exchanger
when circulation of the heat medium is stopped during a
heating period under outdoor temperatures lower than 0°C,
you need to drain the heat medium from the heat exchanger
and blow it o by compressed air.

PROTON GUARD
This equipment is designed for using in buildings with extremely heavy conditions: increased dustiness,
aggressive particles in the air, corrosiveness. Design solutions applied in this series significantly
increase operational safety and life time. Due to using: casings of special construction, heat exchanger
with polymeric protection cover, enlarged thickness of lamellas and interlamellar distance –
PROTON GUARD sets a new standard of industrial air heaters.
Air heaters PROTON G 710 are equipped with three-speed AC-motors.
Air heaters PROTON G 750 are equipped with electronically commutated EC-motors.

It can be optionally equipped with a front panel and louvers.
The air heater PROTON is an element of a
heating system. It is designed for heating air
and its even distribution in buildings. Its work is
based on axial fan functioning, which charges
the air and pass it through a copper-aluminum
heat exchanger in which the heat medium (hot
water) flows at certain temperature. Heated air
is supplied into a room and is directed to the
working area.

5. CONSTRUCTION
Major components of the air heater PROTON GUARD
Diuser
Only plastic diusers are used for this series produced by the method of
vacuum molding. In addition to creating a form around an impeller, the diuser
performs a role of a body to fix a fan and additional stiening ribs are provided
ad hoc. The diuser is fixed to a heat exchanger by a flat side, that enables to
fully use air charged by a fan to move through lamellas of the heat exchanger.
Fan
The fan is fixed in a plastic diuser on the back of the unit, thanks to which air
can be eectively charged in a heat exchanger. The diuser is made in the
shape of a ring around fan blades as well as creates a body of the air heater.
Fans applied are axial and can have either single-phase electronically
commutated or single-phase asynchronous motors. These fans are
manufactured in a single production process, tested and balanced by the
manufacturer, installed on a protection grill which protects the heater from
falling in of debris, leaves etc. as well as prevents possible personnel injures or
death caused by rotating fan blades.
PROTON G 710 with single-phase asynchronous motor
This type of motors can work only with nominal voltage of 230 V. To start the
motor a capacitor is needed, so the latter is installed into the motor, and this
eliminates the necessity of using external elements to be connected to the
power network. The use of the single-phase motor enables regulation of
rotation speed by additional step-down transformers or to use of additional
contacts from motor windings with dierent powers.
PROTON G 750 with electronically commutated motor
The motor contains a built-in electronic controller which enables to set rotation
speed. This technology makes possible remote smooth regulation of the motor
and increases its eciency. Using appropriate control elements in an automatic
mode you can maintain necessary speed for as comfortable as possible relation
between noise of blades and heating power of the unit. Construction of these
motors doesn’t dier from asynchronous ones.
Heat exchanger
The heat exchanger consists of copper tubes and aluminum lamellas pressed on
them. It is equipped with copper pipes with threading connection (external
thread 3/4”). The copper-aluminum heat exchanger is distinguished by high
eciency, is not exposed to corrosion if you don’t use substances and
impurities in a heat medium causing copper corrosion. Maximal parameters of
heat medium supply are 105 °C/1,6 MPa. The air heaters PROTON GUARD are
equipped with the heat exchanger with polymeric protection cover with
enlarged thickness and interlamellar distance, that allows to use them
eectively in the agriculture sector.

Data on operating characteristics of air heater PROTON, when using heat medium with diering temperatures, is to be provided on demand.
There is danger of heat exchanger defrosting (breakage) if room temperature falls lower than 0 °C.
As maximal pressure of the heat medium is 1,6 MPa, the water cir cuit system must have protection from pres sure rise higher than accepted value.
