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
Use only under conditions in which no water hammer will occur. The
impact of water hammer may damage the product, leading to fluid
discharge, which may cause burns or other injury.

If water hammer due to steam backflow in the condensate
recovery line is expected, installation of a check valve vertically
and as close as possible to the recovery line is recommended
When the rise in piping is 30 m (100 ft) or farther from the
PowerTrap
, installation of a check valve is recommended for
the prevention of return water hammer
