Proper Installation - TLV JL9X Manuel D'utilisation

4. Proper Installation

CAUTION
1. Before installation, be sure to remove all protective seals.
2. Install a bypass valve and inlet and outlet isolation valves for use in the event of trap failure
or when performing maintenance.
3. Install a strainer (40 – 60 mesh) ahead of the trap.
4. Before installing the product, open the inlet valve and blow out the piping to remove any
piping scraps, dirt and oil. Close the inlet valve after blowdown.
5. Install the product so that the arrow on the body is pointing in the direction of flow.
6. The trap should be inclined no more than 5° horizontally and front-to-back. Be sure to leave
adequate clearance for a maintenance space above the trap cover.
7. Connect outlet piping. Be sure to size outlet piping large enough to accommodate any flash
steam that may form to prevent any increase in back pressure and allow at least 1 m (3.3ft)
straight piping to avoid possible pipe erosion.
8. Open the inlet and outlet valves and check to make sure that the product functions properly.
If there is a problem, determine the cause using the "Troubleshooting" section in this manual.

NOTE: If the trap inlet pressure exceeds 0.7 MPaG (100 psig), in order to ensure that an increase
in back pressure does not prevent the rated flow capacity from being achieved, increase
the size of the piping immediately after the trap to 80 mm (6").
(Outlet pipe size should always be properly calculated, contact TLV for assistance.)
Inlet, outlet and bypass valves must be full bore valves.
This diagram is for illustration purposes only. For actual installation, piping design must
be performed by qualified personnel.
• Installation, inspection, maintenance, repairs, disassembly, adjustment
and valve opening/closing should be carried out only by trained
maintenance personnel.
• Take measures to prevent people from coming into direct contact with
product outlets.
• Install for use under conditions in which no freeze-up will occur.
• Install for use under conditions in which no water hammer will occur.
