Installation Guidelines & Procedures for B & D MFG., INC.
Smart Pump Multizone Flow Center
Electrical Service & Connections –
The Smart Pump Multizone Flow Center requires a dedicated 240 volt single phase circuit. Wire and fuse sizes
shall be in accordance with local codes and that of the National Electric Code. Low voltage wiring must be
isolated from primary voltage lines and connections.
Maximum Rated Amperage of Yaskawa VFD –
Input Voltage: 1x230V
Output Voltage: 3x230V
2HP & 3 HP Drive (0012): 12 Amps
5HP (0018): 17.5 Amps
Stop Function –
The system must be able to maintain a static pressure between the solenoid valves and the check valve before
the pump. If the system is not able to maintain this static pressure, then the system will not have a stop
function. This can be done by allowing continuous flow through the smallest heat pump and still allowing the
solenoid valves to close on all other heat pumps to reduce the flow. resulting in less energy consumption.
(refer to diagram on page 13)
Flow Center Canister Placement Requirement –
A level location with 36" of clearance around the canister is required. This allows enough room to hook-up the
CR series pump and associated piping. An allowance for 36" of clearance on the top of the canister (between
lid and ceiling) for insertion of an optional flow meter tool and system fluid access.
