Function The fill and flush pump cart is portable, pre-assembled and leak-tested for a safe, quick and clean way to fill and flush solar, geothermal and hydronic heating systems. Preassembled with a leak test pressure gauge, the Fill and Flush cart makes it easy to test a system. The Fill and Flush Cart was designed for easy manuevering, with 10 inch tires and back arm bars, this cart will manuever any stair or landscape and ease the process loading into a van or truck. Another feature of the cart is the attached pump. With a 1/2 HP (120 V AC) pump, providing up to 100 psi, giving the power needed to clear all of the air out of the solar thermal system.

CURVES AND PERFORMANCE DATA
Head H (feet)
Head H (meters)
The amount of fluid which flow through a hydronic system during filling and flushing is determined based on the pump size.
Flow Rate
This relationship is described in the graph to the left, demonstrating the physical properties of the pump connected to the cart. As an example, at 100 ft of head, the pump is producing a flow rate of 7 gallons per minute. In projects that require high psi, the pump on the Caleffi Fill and Flush cart can produce up to 220 ft of head and a flow rate of more than 13 gallons per minute. The fill and flush cart pump has 1/2 HP (120 V AC) cast iron motor.

Operating principles The fill and flush pump cart is portable, pre-assembled and leak-tested for a safe, quick and clean way to fill and flush solar, geothermal and hydronic heating systems. Preassembled with a leak test pressure gauge, the Fill and Flush cart makes it easy to test a system. Connect the fill/purge valves to the fill and flush system, allow fluid to circulate and remove air and dirt in system. Pump system to desired pressure, use the liquid pressure gauge to observe system pressure. If the system holds its pressure, the system is leak free.

Maintenance and Preventitive Care After use of Caleffi Fill and Flush Cart: 1. During operation, running pump without fluid could lead to significant damage, be sure not to operate pump without fluid. 2. Unscrew dirt filter and remove any dirt or buildup remaining. 3. Leave residual glycol fluid inside the pump and tank. 4. Make sure to collect any excess fluid and dispose of in a safe and secure manner.
5. Store hoses inside tank after use. 6. Store in controlled climate with lid properly sealed on to avoid unneccesary wear and tear, and to control cleanliness of glycol tank. 7. Always store the pump cart with some inhibited glycol to prevent freezing. This also protects the pump body from corrosion.
