2 Set Up Instructions for DVFP Inspect the packaging of the equipment to confirm that nothing was damaged during shipping. Remove the system from the packaging. Make sure everything is included and without damage. Below is a checklist with everything you should have received. The system will already be assembled and should arrive in one piece. 1) Pump (Figure 1) 2) Variable Frequency Drive (VFD) (Figure 2) 3) Pressure Tank (Figure 3) 4) Plumbing Figure 1: Pump Figure 2: VFD Figure 3: Pressure Tank Call Diamond H2O right away if anything is missing. Contact the freight company immediately if anything is damaged. Diamond H2O will not be liable for any damage received after shipping. Packaged By: Received By: Date: Date: Table 1: System Specifications Model HP Suction Discharge psi DVFP " 1.5" 70 gpm DVFP " 1.5" 100 gpm DVFP " 2" 140 gpm 1. AWG will change depending on length of wire (values are for a max 300ft from input). 14 AWG wire can be used for any system using less than 100ft of wire from power supply. 2. With properly-sized circuit breakers, the Drive is protected from short circuit on the input and the output. 3. Minimum 240V generator size. pg. 2

3 Additional Pressure (psi) DVFP Series Variable Frequency Drive - Product Manual DVFP DVFP-70 DVFP Flow Rate (gpm) Figure 4: DFVP Sizing Recommendations Warnings All installation, service work, and inspections must be done by a qualified electrician. Risk of highvoltage electrical shock from EMI/RFI filter inside drive. Can shock, burn or kill if the front cover of the PENTEK INTELLIDRIVE is open or removed while power is connected to the Drive or the Drive is running. The front cover of the Drive must be closed during operation. Make all wiring connections, then close and fasten the cover before turning on power to drive. NEVER open the box when power is connected to Drive. Before doing any service or maintenance inside Drive or when connecting or disconnecting any wires inside Drive: A. DISCONNECT power. B. WAIT 5 minutes for retained voltage to discharge. C. Open box. Before starting any wiring or inspection procedures, check for residual voltage with a voltage tester. NEVER o connect power wiring to Drive before mounting the box. o handle or service Drive with wet or damp hands. Always make sure hands are dry before working on Drive. o reach into or change the cooling fan while power is applied to Drive. o touch the printed circuit board when power is applied to Drive. pg. 3

4 Warnings continued Do not modify equipment. Do not use power factor correction capacitors as they will damage both motor and PENTEK INTELLIDRIVE. Do not remove any parts unless instructed to do so in Owner s Manual. Do not use a magnetic contactor on Drive for frequent starting/stopping. Do not install or operate Drive if it is damaged or parts are missing. Before starting Drive that has been in storage, always inspect it and test operation. Do not carry out a megger (insulation resistance) test on the control circuit of the Drive. Do not allow loose foreign objects which can conduct electricity (such as screws and metal fragments) inside Drive box at any time. Do not allow flammable substances (such as oil) inside Drive box at any time. Ground Drive according to the requirements of the National Electrical Code Section 250, IEC 536 Class 1, or the Canadian Electrical Code (as applicable), and any other codes and ordinances that apply. Setup Instructions 1. Place the System near a water source and a power source. Decide where you would like to place the system. Ideally, it should be very close to the water source and within 25 feet of a circuit breaker. The VFD should be mounted on the wall with a few inches of clearance on every side of the VFD. This will allow free air flow to the unit. 2. Connect the Pump to the Water Source System piping should be at least one commercial pipe size larger than pump connections and flow velocity should not exceed eight (8) feet per second. In pool installation, flow velocity should not exceed six (6) feet per second. The inlet of the pump is shown in Figure 4. Follow all local codes. Pump Outlet Pump Inlet Figure 5: Pump Diagram pg. 4

5 A. Pipe or tube a line from the Water Source to the Pump Inlet. a. Take Care to align piping with pump case. Misalignment or excessive pipe strain can cause distortion of pump components resulting in rubbing, breakage, and reduced pump life. B. Make sure there is no pressure on the connections. a. Support the pipe so it doesn t affect the connection to the pump. b. Check the pump alignment. C. Follow the recommendations in Figure 6 when attaching the piping. Figure 6: Plumbing recommendations 3. Connect the variable frequency drive (VFD) to the circuit breaker. 1. Carefully remove the cover from the VFD Enclosure 2. Inspect the system to verify the wiring is set up correctly. 1. Check that the pump is wired to the U, V, and W lines of the VFD controller. 2. Check that three wires are connected from the R, S, and T lines of the VFD Controller to the Fuse block. pg. 5

6 2. 1. U (T1), V (T2), W (T3) 3. Connect the positive (red, DIN terminal 1) wire of the pressure transducer to the 24V terminal of the VFD, the negative (black, DIN terminal 2) wire to the AI terminal of the VFD, and the ground wire of the pressure transducer to a ground. 4. Connect GND to GND and NO as shown below. Connect 24V to COM as shown below. 5. Set the AI Type Selection switch to ma (I). 6. Connect the power to the VFD. Set to I Pressure Transducer pg. 6

7 4. Set the Pressure Tank Pressure The pressure tank should be set to 70% of the desired line pressure. For example, if the desired pressure was 60psi, the pressure tank should be set to 42psi. 5.
