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.
CAUTION
Steam System Example
For non-standard options, please refer to the additional instruction manual(s) provided.
1. Standard Installation Example
The example below shows the inlet piping is connected to the inlet of GT5C in the
same way as a standard steam trap. The condensate inlet pipe [Si] acts like a
condensate reservoir. Refer to
“Sizing the Condensate Reservoir Pipe” at the end of
this section for the size of condensate inlet pipe [Si] (length of Dh).

Backflow
Water Hammer
Prevention
Check Valve
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.
Inner diameter should be
at least 8 mm (

*Refer to diagrams shown in
“Installation Procedure” and “(4) Inlet and Outlet Piping” in this section for the
length of condensate reservoir (Dh) in cases where the exhaust pipe is eliminated and there is vertical piping
on the pumped medium inlet due to elevated position of the equipment condensate outlet.
