Note: Before actioning any installation observe the ‘Safety information’ in Section 1.
Referring to the Installation and Maintenance Instructions, name-plate and Technical Information
Sheet, check that the product is suitable for the intended installation.
3.1
Check materials, pressure and temperature and their maximum values. If the maximum
operating limit of the product is lower than that of the system in which it is being fitted,
ensure that a safety device is included in the system to prevent overpressurisation.
3.2
Determine the correct installation situation and the direction of fluid flow.
3.3
Remove protection covers from all connections before installation.
3.4
Install the trap below and as close as possible to the drainage outlet; make the connections
so that the trap is positioned with the arrow on the body pointed vertically downwards.
3.5
Insert a strainer with an adequate capacity immediately ahead of the trap to prevent damage
to the device’s internal components; in systems with steam recovery, it is recommended to
mount a flow indicator downstream of the trap to check that it is working.
3.6
Avoid long stretches of connecting pipe, especially if arranged horizontally or rising.
3.7
With minimum operating pressures, leave a hydrostatic head of at least one metre between
the drainage outlet and the trap.
3.8
If the device to be drained is fitted with automatic temperature control, apply a vacuum
breaker in addition to the hydrostatic head (see Fig. 1).
3.9
If the condensate has to be raised to a height above the trap, install a check valve
downstream of the trap.
3.10
Avoid raising the condensate in the case of low operating pressure (<1 bar) or automatic
temperature control, but use a steam recovery pump.
3.11
Changing the connection configuration
The device is supplied with the connections arranged in a horizontal line and in the direction
of flow shown in Fig. 2a). To change the arrangement of the connections, use the following
procedure, with reference to Fig. 2 and Fig. 3.
- Open the trap by unscrewing the 8 nuts (
13 ) using a size 24 wrench and remove the
cover ( 2 ).
- Disassemble the frame, together with the various mechanisms and ball float, by
unscrewing the 4 screws ( 7 ) with a size 13 wrench.
- Change the body position by moving the connections as desired, to one of the possible
solutions given at Fig. 2 (a, b, c, d).
- Fix the frame to the body in such a way that the float is free to move vertically from top
to bottom and viceversa.
- Close the trap again, making sure that the arrow on the cover is pointing vertically downwards.
- When mounting the frame and closing the cover, make sure that the gaskets are in good
condition and correctly positioned.
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).
