Transported air must not contain any flammable or explosive mixtures, evaporation of chemicals,
coarse dust, soot and oil particles, sticky substances, fibrous materials, pathogens or any other
harmful substances.
DESIGN AND OPERATING LOGIC
The unit is designed for indoor air heating by means of the electric heater and uniform air flow
distribution with the fan and louvre shutters.
The special unit design enables quick air heating in large premises due to high-efficient electric
heater and a powerful fan. The electric connections and control connections are performed in a
terminal box at the side unit panel.
UNIT MOUNTING AND SET-UP
THE UNIT INSTALLATION IS ALLOWED BY QUALIFIED PROFESSIONALS AFTER
CAREFUL STUDY OF THE USER’S MANUAL.
While mounting the unit provide the minimum required access to the unit for maintenance and
repair.
The unit is designed for wall mounting or mounting to any other vertical surface or ceiling mounting
with fixing bracket.
While mounting the unit provide free air flow to the unit intake opening. The minimum distance from
the wall or the ceiling to the unit is 300 mm.
WARNING!
REDUCING MINIMUM DISTANCE FROM THE UNIT TO THE WALLS OR CEILING ADVERSELY
AFFECTS AERODYNAMIC AND HEATING CHARACTERISTICS AND THE UNIT SERVICE LIFE.
UNIT INSTALLATION WITH MKP-AOW MOUNTING KIT
The mounting kit MKP-AOW (available upon separate order) is used for ceiling mounting of the unit
with mounting studs or chains.
The unit mounting example with the mounting kit MKP-AOW is shown below.
CONNECTION TO POWER MAINS
DISCONNECT THE UNIT FROM POWER MAINS PRIOR TO ANY ELECTRIC
INSTALLATION OPERATIONS. CONNECT THE UNIT TO A CORRECT INSTALLED SOCKET WITH A
GROUNDED TERMINAL. ANY INTERNAL CONNECTION MODIFICATIONS ARE NOT ALLOWED
AND RESULT IN WARRANTY LOSS.
The unit must be operated only jointly with an automation system that enables the following
functions:
1. Disabling power supply to the heater when the fan is off.
2. Air supply to the electric heating elements for heat removal within 2 minutes after the unit is
off.
3. Maintaining minimum air speed 2 m/s to avoid heating elements overheating.
4. Power supply cut-off in case of overheating of the electric elements by means of the thermal
switches mounted inside of the heater casing
5. Automatic heating capacity control to keep the maximum air temperature downstream of
the electric heater +40 °C to avoid the heater overheating and reducing its service life.
The unit with a selected control system is rated for connection to three-phase ac 400 V / 50 Hz power
mains. Connection to power mains of the unit with any control system must be performed with
insulated, durable and heat-resistant conductors (cables, wires).
The external power input 400 V / 50 Hz must be equipped with an automatic circuit breaker built into
the stationary wiring to disconnect all the power mains phases. The circuit breaker QF position must
ensure free access for quick power-off of the unit. The circuit breaker trip current must be in
compliance with the current consumption of a specific E-HP model.
The recommended circuit breaker trip current and the cable cross sections for various Е-HP models
are given un the table below. However, the conductor selection shall be based on the maximum
permissible wire heating depending on the wire type, its insulation, length and installation method
(i.e. overhead, in channels or inside the walls)
Terminal block x1 (in the control circuit):
RT1 –temperature sensor;
TK1 –self-resettable thermal switch (normally closed contact), response temperature +50 °C;
TK2 –manually resettable thermal switch (normally closed contact), response temperature +90 °C;
Connect the thermal switch contacts in series to the circuit of the starter (contactor) actuating coil
that starts the unit or the heater. In case of overheating one of the contacts gets broken and
switches the starter actuating coil off to cut power off and stop the motor.
Terminal block x2 (heaters):
L1, L2, L3 –phases (for Е-HP 9,12,15);
1L1, 1L2, 1L3, 2L1, 2L2, 2L3 –phases (for Е-HP 18,24,30);
N –neutral;
PE –protecting grounding.

UNIT WIRING DIAGRAM
The emergency thermal switches are actuated in case of unscheduled power outage or wrong
selected control system.
The automatically resettable thermal switch with response temperature +50 °C resets to operating
condition after the heater cooling.
Reset of the manually resettable thermal switch with response temperature +90 °C is as follows:
Disconnect the unit from power mains.
Let the heater fully cool down.
Remove the emergency thermal switch cap.
Press the Reset button using a rod of non-conducting material. Troubleshoot the unit overheating
and make steps to prevent it.
MAINTENANCE
Regular routine maintenance is required. The unit must be cleaned of dust once in year by means of
air blushing. Disconnect the unit from power mains prior to the unit cleaning.
