6.2 Warning and caution for installation
Warning
1. Condensate may blow out from vent port following driving pressure drop or stop or failure of the
product. Connect a pipe to the port and extend the pipe to safe place.
* Failure to follow this notice may scald your skin by blowout of condensate.
Caution
1. Before installing the product, remove foreign substances and scale from the piping, and note that
seal materials must not flow into the inside of the product or piping.
* Commingling of foreign substances such as scale or seal material leads to malfunction of the
product.
2. Before connecting pipes, check the condensate inlet, condensate outlet, driving fluid port and vent
port. (See 6.1. Piping example.)
* The product does not function properly if piping is not connected correctly.
3. Install the product horizontally, with vent port facing upward.
* The product does not function properly if installation direction is not correct.
4. Connect the product to piping firmly.
* Failure to follow this notice may cause burn injury by leakage of condensate from joints due to
vibration.
5. Use union joints, etc. for connection with pipes. (See 6.1. Piping example.)
* If union joints, etc. are not used, removal of pipes may become impossible or require more time
in disassembly/assembly for maintenance/inspection.
6. Do not apply any shocks such as water hammer. Avoid using quick open/close valves at inlet
/outlet side of the product.
* Failure to follow this notice may cause burn injury by blowout of condensate caused by
excessive shock on the product.
7. Do not disassemble the product unless necessary.
* Failure to follow this notice may hamper proper operation of the product.
8. Attach strainers in front of condensate inlet and driving fluid port. (See 6.1. Piping example.)
* If strainers are not attached, the product does not function properly due to intrusion of dust, etc.
into the product.
9. Check valve is not connected to the product. Be sure to install check valve at inlet and outlet of the
product. (See 6.1. Piping example.)
* Without check valve, the product do not function as pumping trap.
10.
If driving fluid is steam, install a steam trap to the pipe on driving fluid port for condensate
discharge. (See 6.1. Piping example.)
