6. OPERATION
In bi-metallic traps, the main element is the valve and the bi-metal itself. Bi metal
is a composite material consisting of two separate plates with different expansion
coefficients.
OPENING
When the system is cold, the valve is open and non-condensable gases and cold
condensate are discharged. While the system is in operation, the bi-metallic
plates, which contract with the cooling of the condensate coming to the trap, push
the valve from the seat and allow the condensate to be discharged.
CLOSING
When hot condensate comes, the amount of bending at different temperatures is
proportional to the length of the protrusions, so the long protrusions and then the
short ones are bent respectively. Therefore, they gradually pull the valve towards
its seat. As the temperature increases, the applied force also increases and
stabilizes the bearing. As can be understood from its working principle, it keeps
the condensate in the steam chamber and waits for the temperature to drop a few
degrees below. This feature should be considered in practice .
INSTALLATION STEPS
a- Unscrew the cover body connection bolts.
b- Take out the capsule.
c- Unscrew the capsule seat.
d- Clean the entire body, interior parts and gasket seating surfaces.
e- Use a new cover gasket while assembling. Check the operation of the
capsule. Replace with a new one if necessary.

5. INSTALLATION
Before the installation, you should read safety instructions carefully.
a- Check the label and technical information sheet if the product is
suitable for the required installation.
b- Check the maximum pressure and temperature values. lf the pressure
in the system is higher than the maximum value of the product, provide the
use of safety tools in order to prevent the excess pressure.
c- Remove the product from package carefully. Parts of the product may
resemble the packaging element. In this case, please contact your dealer.
d- Consider the temperature of the released condense as 100ºC if there
is discharge of condense into atmosphere. Be sure that the system is
working correctly after the installation and maintenance.
e- Be sure to install on the correct equipment by referring to the
product label.
f- Make sure that the straps are fully seated and tightened.
g- Tighten the jacket by using metal wires.
