We congratulate you on your choice of the EX4500/EX6100 Centrifugal Pump! It has been carefully designed using the advantages of
today's technology and carefully constructed to give you the dependability of yesterday. To insure proper performance, we urge you to
carefully follow the instructions in this manual. If you have any questions, call your nearest distributor or EasyPro for assistance.
INSTALLATION
Please read carefully! When properly installed the EX Series Pump will provide dependable trouble-free service.
1. Locate the pump as near the water source as possible. A fl ooded suction situation is preferred. The pump is not self-priming, there-
fore, if the fl uid level is below the pump, a swing check valve must be installed and the pump primed prior to start-up. (Figure 2)
2. Mount motor base to a secure, immobile foundation.
3. Use only plastic fi ttings on both the intake and discharge ports. Seal pipe connections with Tefl on™ paste. These fi ttings should be
self-supported and in neutral alignment with each port. (i.e. Fittings must not be forced into alignment which may cause premature
line failure or damage to the pump volute.) For non-fl ooded installations, a strainer basket and check valve are recommended.
4. Never restrict the intake. Keep both input and discharge lines as free of elbows and valves as possible. Always use pipe of adequate
diameter. This will reduce friction losses and maximize output.
5. This pump is not self-priming! It must not be run dry! We recommend a fl ooded suction installation. Please read carefully! When prop-
erly installed, the pump will provide dependable, trouble-free service.
