INTRODUCTION
These instructions cover the use of the B&D Power-Flow Purge Cart Part No. GT-304SS-1.5 and GT-304SS-2. The
Power-Flow Purge Cart is designed for flushing out air and debris in the loop field. It can also be used to introduce
glycol into the system. The package contains a water holding tank, cart with solid foam tires, hose with camlock
connections and a lift out filter screen for easy removal of debris.
SAFETY PRECAUTIONS
*Electrical Supply to flush cart must be a single 20 amp, 120 volt circuit. If using extension cord, do not exceed
manufacturer’s rating for cord.
*Servicing of closed loop systems should be performed only by trained and qualified service personnel. Proper
precautions should be taken to minimize risk of electrical shock when using a flush cart. Wear proper safety glasses
and work gloves.
*When transporting the cart, be sure to keep cart in an upright position and secured to avoid any damage to the
flush cart.
*Be sure to drain the tank after each use to prevent damage to the rubber seals of the pump. It is best to store the
flush cart in an area free of freezing temperatures.
*Must Read and Follow Anti-freeze Manufacturer’s Recommendations and Procedures for adding anti-
freeze solution to the system.

ASSEMBLY INSTRUCTIONS
Open the crate and install the 13” wheels. That’s it, because we have mounted our stainless steel tank, pump, motor
and hoses securely to a heavy duty cart for easy handling. Everything has been factory tested so that when it arrives,
it’s ready to go.
CAUTION: Must read all instructions in this manual before operating the Power-Flow Purge Cart.

How to Flush a Loop Field
OPERATING INSTRUCTIONS
Connect the two provided camlock connections to the flush ports on the loop field piping system using sealant tape or
compound to prevent leaks.
NOTE:

may control the amount of water supplied to the tank by regulating the valve on the drainage port.

observing the water level at the discharge valve. When water level is at the level of the discharging valve (3.), close the
valve and allow the water to continue filling the tank to top of elbow. This will purge the air from the pump while filling
the tank, preventing an air lock.
Check screen position in tank to be sure it is below the return elbow, so all water goes through the screen to catch
debris.
NOTE
:
System should be filled with clean potable water.
Connect the provided hoses between the camlock connections on the purge cart with camlock connections now mounted
in the flush ports.
Make sure the power switch is in the off position before plugging in the power supply.
Plug in power supply for flush system using only a
20 amp, 120 volt circuit
. If using an extension cord, do not exceed
manufacturer’s rating for cord.
Open the valves on all of the fill and flush ports into the position that allows flow to and from the loop field.
Open the ball valves on the supply and return water lines of the purge cart system.
** IMPORTANT ** Keep water supplied to flush system tank to prevent pump from being run dry. Do not
** NOTE **
allow flush tank to overflow.
Turn on pump.
NOTE
:
If the pump is air locked, then turn the pump off. Disconnect the supply hose from the flush
port and place in the top of the tank and turn pump on. This will prime the pump and allow water to
circulate directly back to the tank. Re-attach the hose and begin the purging process over again.
