3. GENERAL
3.1Descr�pt�on of the Pump
Alarko Opt�ma�s abrand new type of c�rculat�onpump wh�ch regulates�ts speed accord�ng to the
system needsby the ECM (Electron�c Commutated Motor) technology and the controller on�t, as well
as savesenergy w�th �ts var�oustypesof operat�ng mode cho�ces. The operat�ng modesare manual,
constant pressure and var�able pressure. See sect�on7.1.1, 7.2.2and 9. The pump operates
accord�ng to the operat�ng mode and head sett�ngswh�ch are setfrom the controller.
The ma�n components and the�r mater�als are g�ven�n the follow�ng f�gure and table.

3.2Appl�cat�ons (Intended Use)
Alarko Opt�mapumpsare developed for the c�rculat�onand pressur�zat�onof the water flow�ng �n the
heat�ng and a�r cond�t�on�ng systemslocated �n the res�dent�al, commerc�al and �ndustr�al
establ�shments.
CAUTION
Opt�ma pumps can be used only for thepurposes that are stated �n th�s
manual. Themanufacturer and thedealer are not respons�ble forthe
results of them�suse.
3.3Pumped L�qu�ds
Asthe l�qu�d, only water should be used. It should be free from sol�d part�clesand �s notm�xed w�th
any add�t�ves, e.g. ant�-freeze. To avo�d any k�nd of scal�ng or corros�on, the water w�th�n the system
should meet the cr�ter�a below:

3.4Operat�ng Cond�t�ons
Alarko Opt�mapumpsare developed for the c�rculat�onand pressur�zat�onof the water flow�ng �n the
heat�ng and a�r cond�t�on�ng systemslocated �n the res�dent�al, commerc�al and �ndustr�al
establ�shments.
Input Voltage: S�ngle Phase 230 Volts AC (± 10%) and 50 Hz (earth protected).
Water Temperature: Up to +110°C
System Pressure: For m�n�mum and max�mum water pressure see Table 4.2 and Table 4.3
Amb�ent Temperature: -10°C to +40°C
Thecond�t�ons (voltage, pressure, temperature) of thepump wh�le
operat�ng should be between the l�m�ts g�ven above.

3.5Insulat�on Shells
The �nsulat�onshell �s des�gned to m�t�gate the thermal losses�n heat�ng systemsand del�vered w�th
the pump. It �s made of polypropylene foam and thoroughly mounted onthe pump by �ts perfectly
f�tt�ng des�gn.
Remove the �nsulat�on shells from the hous�ng before the pump �nstallat�on. See F�gure 3.2.

L�ftthe pump by observ�ng the local l�ft�ng and handl�ng regulat�ons.
4.3Transportat�on and Storage
Amb�ent Temperature dur�ng the Transportat�on and Storage: -25°C to +40°C
The pump should be protected from mo�sture, �mpacts and frost dur�ng the transport and storage.
CAUTION
Improper transportat�on or storage may lead to damage to the product.
It �s adv�sed to check and exam�ne the product whether �t �s the ordered type and del�vered
undamaged.

6. PUMP INSTALLATION
Mechan�cal and electr�cal �nstallat�on must be carr�ed out by qual�f�ed
personnel and �n accordance w�th the�nstruct�ons on th�s manual and
also w�th appl�cable regulat�ons.
CAUTION
Before any �nstallat�on, thep�pework should be checked for
contam�nat�on and flushed �f there �s any.
6.1Pos�t�on�ng
Thepump should be �nstalled �nto thep�pework w�thout any stra�n or
bear�ng the we�ght of the p�pework.
The f�guresg�venbelow are to be taken�nto cons�derat�on dur�ng the �nstallat�on.
The pump must be connected to the p�pework w�thoutany stra�n, do notbear the we�ghtof the
p�pework and the motor shaftmust be parallel to the ground.
