Installation and Operating Manual
Art. No. 13512-.../13513-...
Version 10.2012 Page 5
Optional installation of metal filter cover PS = 16 bar
•
Turn retaining ring anti-clockwise
to loosen it, hold and remove filter cover
•
Take care not to damage the O-ring. Replace it if necessary (a new O-ring must be oiled!)
•
Hold the metal filter cover and the O-ring in position and tighten by hand by turning the retaining ring
clockwise.
•
Check for existing leaks, make sure no leaks will occur!
START-UP
If a pressure test is required before starting up the oil-fired installation, e.g. according to OFTEC Technical Book
3 section 5, the GS Pro-Fi 3 can be subjected to a test pressure of a maximum of 6 bar with plastic cover, or 16
bar with metal cover. Avoid any pressure increase beyond 6 bar or 16 bar caused by heating of the test medium.
Higher test pressures can damage the GS Pro-Fi 3.
Before start-up, the GS Pro-Fi 3 and all the connections must be checked for leaks. This test can be included in
the pressure, leak, or function test of the oil-fired installation. Any leaks must be sealed, e.g. by re-assembly of
the connections with new conical nipples or tightening of the screwed connections.
Observe the safety information under
MAINTENANCE
!
Unless defined otherwise in the start-up
instructions of the burner/furnace
manufacturer, proceed as follows:
Deaerate the installed oil lines (burner flow
and return lines) and the deaerator with a
suction pump and fill them with fuel. To this
end, open the quick-acting valve
and the
deaeration screw
. Connect the suction
pump directly at the deaeration screw by
means of the enclosed adapter, Art. no.
13610-60. We recommend continuing the
suction process until the upper cover is filled
with oil as well. After that, re-tighten the
deaeration screw.
OPERATION
In ongoing operation of the oil-fired installation, the GS Pro-Fi 3 does not require any attendance. Set the
integrated quick-acting valve
- a ball valve - to the
‘
open
’
position
by turning the handle in flow direction, as
shown in the figure on Page 1.
Turn the handle of the quick-acting valve to ‘closed’ position – vertical to the flow direction – for longer standstill
periods or MAINTENANCE measures.
Due to the intelligent design of the GS Pro-Fi 3, the full fuel oil column will be available on burner start-up without
any noticeable air particles.
INFORMATION ON THE FILTER ELEMENT
:
There is no universal filter element. Select a filter element according to the specification of the burner
manufacturer, taking into account filter fineness and the respective operating conditions. The IWO Institute for
Economically Efficient Fuel Oil Heating Systems recommends filter elements of sintered plastic of a mesh width
of 30 to 75
µ
m. For oil-fired installations with so-called “low NO
x
burners“ and burners of lower thermal output,
GOK filter elements FEINFILTERUNG of a mesh width of < 35
µ
m are recommended.
SAFETY FUNCTION
In case of hose rupture in the flow
or return line
, the aspired ambient air will cause the burner to go to
“lock out” state.
For pressure testing, unscrew the manometer blind screw
and screw in the manometer G 1/8.
Make sure that the O-ring remains in the manometer blind screw.
After testing, unscrew the manometer and screw in the manometer blind screw with O-ring.
