3.7
Avoid long pipe lenghts, especially if arranged horizontally or rising.
3.8
With minimum operating pressures, leave a hydrostatic head of at least one meter between
the drainage outlet and the trap.
3.9
If the device to be drained is fitted with automatic temperature control, add a vacuum breaker.
3.10
If the condensate has to be raised to a height above the trap, install a check valve downstream
of the trap.
3.11
In case condensate return is at a higher level and operating pressure is low (< 1 bar g) or the
system is temperature controlled, please consider the adoption of a steam recovery pump.
3.12
In order to ensure an efficient discharge of incondensable, it is recommended to connect the
balancing connection of the trap to the drained system. For convenience of maintenance it
is recommended that a union is fitted in the balance line near to the trap cover.
Note:
If the trap is to discharge to atmosphere ensure it is to a safe place, the discharging fluid may
be at a temperature of 100°C (212°F).
4. Commissioning
After installation or maintenance ensure that the system is fully functioning. Carry out tests on any
alarms or protective devices. Always open isolation valves slowly until normal operating condition
are achieved. Check for leaks and correct operation.
5. Operation
Ball float steam traps quickly remove air, have continuous, modulating condensate discharge, and
can adapt immediately even to large or sudden variations of flow and pressure.
Given the absence of air eliminator, the drainage of incondensable can be ensured by connecting
a balance line to the drained system.
Drainage of Heat Exchangers
FTC23 is not fitted with internal air eliminator
due to his high sensibility to contaminants.
For this reason the trap must be vented to
the H.E. (Fig. 1).

Drip Trap
In this case, it is not mandatory to vent the
trap. It depends on the specific working
conditions (Fig. 2).
