Introduction Thank you for purchasing the PowerTrap. This product has been thoroughly inspected before being shipped from the factory. When the product is delivered, before doing anything else, check the specifications and external appearance to make sure nothing is out of the ordinary.
The three types of cautionary items above are very important for safety: be sure to observe all of them as they relate to installation, use, maintenance and repair. Furthermore, TLV accepts no responsibility for any accidents or damage occurring as a result of failure to observe these precautions.

CAUTION Be sure to use only the recommended components when repairing the product, and NEVER attempt to modify the product in any way. Failure to observe these precautions may result in damage to the product and burns or other injury due to malfunction or the discharge of fluids.
General Description DO NOT use this product outside the recommended operating pressure, temperature and other specification ranges. Improper use may result in CAUTION 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.
Operation 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 CAUTION the discharge of fluids. (1) When condensate flows from the condensate inlet pipe through the inlet check valve into the body of the unit, the air in the body escapes through the exhaust valve (which equalizes the internal pump pressure to the pressure of the condensate source) and the float rises, as shown in (1) below.
Specifications DO NOT use this product outside the recommended operating pressure, temperature and other specification ranges. Improper use may result in CAUTION 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.
Installation DO NOT use this product outside the recommended operating pressure, temperature and other specification ranges. Improper use may result in CAUTION 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.
NOTE: In closed system applications, the motive medium must be compatible with the liquid being pumped. If a non-condensable gas such as air or nitrogen is used as the motive medium, please consult TLV for assistance. Condensate Supply Se Exhaust Pipe...

(3) Pressure Reducing Valve on the Motive Medium Supply Piping: !"When the motive medium pressure is greater than 1.05 MPaG (150 psig, 10.5 barg), install a TLV COSPECT Series pressure reducing valve in order to reduce the motive medium pressure to the PowerTrap. Use good piping practices when selecting the installation location for COSPECT.

Size of the Condensate Receiver / Reservoir Pipe When selecting the receiver/reservoir pipe for the PowerTrap, select from among the following 3 conditions: Flash Steam When large quantities of flash steam are involved (For open systems using steam) a) Determining the amount of flash steam: Condensate Receiver Amount of flash steam Fs = Qd ×...

Installing Several PowerTrap Units in Parallel Refer to the figure below for the piping when several PowerTrap units are to be installed after the same condensate inflow pipe. The size of the condensate inflow pipe and condensate recovery line is determined by the number of PowerTrap units installed.

Operation and Periodic Inspection • After all piping work has been completed in accordance with the specific piping system designed when the decision to utilize the WARNING PowerTrap was made, check once again to make sure that all pipe connections have been tightened, gaskets have been inserted where needed and all parts are securely installed.
motive pressure. (The interval of operation is considered to be the length of time between the start of one discharge cycle and the start of the next discharge cycle.) The interval of operation Tc (s) can be roughly determined using the following formula: Tc = 21,600/Q Tc = 47,600/Qp...

(2) Disassembly Inspection !"Refer to the “Disassembly / Reassembly” section on pages 21 - 28. !"As a general rule, this inspection should be performed at least once every 2 years. !"When inspecting the interior of the unit, check the following items: a) Make sure the snap-action moves up and down smoothly as the float rises and falls.
Disassembly / Reassembly NEVER apply direct heat to the float. The float may explode due to increased internal pressure, causing accidents leading to serious injury WARNING or damage to property and equipment. Use hoisting equipment for heavy objects (weighing approximately 20 kg (44 lb) or more).

2. Removing / Reattaching the Float It is not necessary to remove the float if only the intake (motive medium) and exhaust valves are to be serviced or replaced. It is not always necessary to replace the float when replacing the snap-action unit. The float should be replaced only when there are irregularities such as damage to its exterior or condensate found inside the float.

Troubleshooting NEVER apply direct heat to the float. The float may explode due to increased internal pressure, causing accidents leading to serious injury WARNING or damage to property and equipment.
