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

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.

8
F�gure 6.1: Correct Pump Pos�t�ons Wh�le Vert�cally and Hor�zontally Installed to the P�pework
The pump must be not perpend�cular to the ground.
F�gure 6.2: Incorrect Pump Pos�t�ons
The pos�t�onof the control box can be changed �n order to see and use the d�splay eas�er. To adjust
the pos�t�on, the 4 bolts, wh�ch hook the motor hous�ng and pump hous�ng together, are removed and
the motor hous�ng �s adjusted by rotat�ng �t to the appropr�ate one from theallowed pos�t�ons and
reconnected to the pump hous�ng w�th bolts.
Donot separate themotorhous�ng from pump hous�ng. Rotat�on
operat�on should be done carefully and slowly. Seal damage causes
leakage.

6.2Mechan�cal Installat�on
1. Make sure that all the p�p�ng of the system must be done before beg�nn�ng the �nstallat�on.
2. Close the valvesonthe �nlet and outlets�de to �solate the pump from water flow.
3. Check the coherence of the system pressure and the m�n. & max. pressure values of the pump.
See Sect�on 5.2.
4. Mount the pump to the p�peswh�le tak�ng the arrow onthe pump hous�ng �nto
cons�derat�on. The water flow of the system and the arrow onthe hous�ng must be �n the
same d�rect�on.
5. For threaded p�pe connect�on; place the flat gaskets onto the s�desof the pump. Make
sure that the gaskets do not prevent any water flow.
6. Us�ng astrap wrench or spanner, hold the pump from the pump hous�ng and screw the
nuts. See F�gure 6.4
F�gure 6.4: Threaded P�pe Connect�on
7. For flanged p�pe connect�on; place the suppl�ed flat gaskets onto both s�desof the pump.
Make sure that the gaskets do not prevent any water flow.
8. Use the washers, bolts and nuts g�ven �n the Table 6.1 to f�x the pump to the p�pes.

10
9. Check the F�gure 6.5 for washer, bolt and nut order. See Table 6.1 for the recommended
t�ghten�ng torques for the bolts used �n the pump f�x�ng.

6.3F�ll�ng and Vent�ng
In order to ensure the pump to operate eff�c�ently also w�thout any damage and no�se, the a�r �n the
system must be vented and the system pressure must be betweenthe valuesg�ven�n Table 5.2and
Table 5.3. To fully vent the a�r from the system, the pump can be runfor a wh�le.
A�r vent�ng should not be doneby loosen�ng any bolts of motoror pump
hous�ng.

6.4Cable/Fuse Select�on and Electr�cal Installat�on
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.
Before work�ng on thepump, all poles of thepower supply must be
d�sconnected.
Thema�ns connect�on must havean earth�ng system. If not, thepump
should not be run.
For cable and fuse select�on, Table 6.2 should be cons�dered.

The power cable should not be �n contact w�th the pump or p�pel�ne.
The voltage value of the ma�ns must be �n between the l�m�ts g�ven
�n Table 5.2
It �s recommended to use ares�dual-current dev�ce (RCD) to protect the user and the pump. The RCD
should be chosenaccord�ng to the nom�nal voltage and current of the pump and �t should be able to
tr�p on h�gh frequency leakages(type B) (The tr�pp�ng current should be lower than 3.5mA accord�ng to
the EN 60335).
6.5Parallel/Back-up Operat�on
Whereas the CCM module �s notoperat�ng or �nact�ve, when�nstall�ng more than one pump for back-
up or parallel operat�on, acheck valve must be connected for each pump.
