The pippes should always be installed using supports (Fig. C) to prevent the transmission of
voltage to the pump body. Be careful not to damage any part as a result of over-tightening the pipes
when setting them.
POWER CONNECTION
The installer is responsible to set up the power connections into the power source in
compliance with the corresponding mandatory regulations:
- The international rules require that fixed installations shall incorporate a device assuring the
omnipolar disconnection from the power source.
- Double-check the specifications in the nameplate regarding the pump capacity and the capacity
values in the line are the same. (Fig. D).
- Connect the pump to a physical grounding system. Then connect the phases according to the
diagram in the terminals block or in the nameplate.
- Our monophasic motors are protected against overload by using a thermal device (Overcurrent
cut) installed in the motor winding.
All wiring, electrical connections and grounding of the system must comply
with the official Mexican standard NOM-001-SEDE-2012, Electrical
Installations (use) or local codes and ordinances. You should contact a
qualified electrician.
It is recommended that the pump is fed with a circuit that includes a
differential switch with a current rated no greater than 30 mA
The power cables are coded with the following colors:
GREEN AND YELLOW GROUND
BLACK NEUTRAL
WHITE CURRENT
PRIMING
Fill the pump completely with clean water before starting it. Remove the threaded cap set in the upper side
of the pump body and fill with water up to the orifice level. (Fig. E). Screw on the cap and start the pump.
This operation shall be made before starting the pump for the first time; when it has not been used for long
periods of time or when there is air in the system.
Never operate the pump when
empty. If it happens accidentally turn off the
pump, wait it cools down and prime it using clear
water.
MAINTENANCE
Our pumps do not require maintenance only if the following precautions are observed. When
there is risk of freezing, drain the pump removing the drain cap set in the lower side of the
pump body. Make sure the pump is primed when starting it back. Verify regularly that the foot
valve is clean. If the pump is to be inactive for long periods of time (for example, during
winter) (Fig. F) is advisable to drain it completely, rinse it with clear water and store in a dry
place. If the shaft does not rotate freely, release it with a screwdriver inserting it in the special
slot set in the rear of the pump. (Fig. G). If this does not solve the problem, remove the pump
body loosening the corresponding mounting screws and clean perfectly to remove any debris
setting. Never service the pump when is not previously disconnected from the power source.
