Installation

Install properly and DO NOT use this product outside the recommended

operating pressure, temperature and other specification ranges.

Improper use may result in such hazards as damage to the product or

malfunctions which may lead to serious accidents. Local regulations

may restrict the use of this product to below the conditions quoted.

CAUTION

Use hoisting equipment for heavy objects (weighing approximately

20 kg (44 lb) or more). Failure to do so may result in back strain or other

injury if the object should fall.

CAUTION

Take measures to prevent people from coming into direct contact with

product outlets. Failure to do so may result in burns or other injury from

the discharge of fluids.

CAUTION

Do not use excessive force when connecting threaded pipes to the

product. Over-tightening may cause breakage leading to fluid

discharge, which may cause burns or other injury.

CAUTION

Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.

1. Before installation, be sure to remove all protective seals.

2. 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.

3. Install a bypass valve and inlet and outlet isolation valves for use in the event of trap

failure or when performing maintenance.

4. Install a strainer (40

– 60 mesh) ahead of the product.

5. Install the product so that the arrow on the body is pointing in the direction of flow.

6. The product 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 (3.3 ft) straight piping to avoid possible pipe erosion.

8. Open the inlet and outlet valves and ensure that the product functions properly.

If there is a problem, determine the cause

using the “Troubleshooting” section in this

manual.
