IS THE UNIT SENSITIVE TO LIGHTING STRIKES OR VOLTAGE DISTURBANCES?
Yes. Nothing can prevent direct hits from lightning, however, the Aquavar SOLO2 does use surge arrestors to
prevent damage of indirect strikes and intermittent voltage fluctuations. These protective devices are the same as
used in expensive residential surge arrestors for computers and electronic protection. For additional protection we
recommend an external surge and lightning protection.
CAN I USE THE AQUAVAR SOLO² WITH GENERATORS?
Yes, properly sized and equipped generators can be used. See IM229 for sizing and requirements.
CAN I USE GFCI PROTECTED POWER FOR THE AQUAVAR SOLO² CONTROLLER?
No, like most VFD’s there is a higher leakage current to ground that will cause nuisance tripping. It is designed for
equipment protection on short circuit.
IS MY PRESSURE TRANSDUCER SENSITIVE TO STRAY VOLTAGE AND ELECTRICAL DISTURBANCES?
Yes. The Aquavar SOLO² provided pressure transducer also has electrical surge protection built into the electronics. It
is still recommended to ground the metal piping and sensor casing for plastic pipe to ensure the transducer is bonded
to the same ground point as the incoming power and submersible motor.
WHAT TYPE OF BREAKERS OR FUSES SHOULD I USE?
Fast acting or quick trip type to ensure proper short circuit protection of the drive electronics. Class T fuses or UL 498 /
UL98 rated breakers. Breaker must not have a time delay.
CAN I USE ALUMINUM WIRE (PRE-EXISTING OR NEW INSTALLATION)?
No. Due to the differences in resistance and other properties, it is NOT recommended using aluminum wire (even if
oversized) with the Aquavar SOLO².
WILL THE AQUAVAR SOLO² INCREASE THE LIFE OF MY PUMP AND MOTOR COMPARED TO A CONVENTIONAL
SWITCH SYSTEM?
All things being equal the Aquavar SOLO² reduces the initial start up thrust, and water hammer associated with
conventional systems. Soft-start, soft shut down, reduced in-rush current, reduced wear on mechanical components of
the pump and motor will help extend life. Proper installation and well conditions still remains the key to pump system
longevity.
IS THE PRESSURE TRANSDUCER OPERATION SENSITIVE TO POOR SIGNAL AND ELECTRICAL DISTURBANCES?
Rule of thumb is to not coil excess transducer cable. Coiling the excess cable can lead to stray voltage/electrical
disturbances that can affect the transducer’s ability to correctly read the pressure. Cut excess transducer wire once
correct length is determined and run transducer wire through its own separate conduit whenever possible.
CAN SUBMERSIBLE CABLE (COPPER 75°) BE USED TO EXTEND THE LENGTH OF TRANSDUCER?
Yes, Single and double jacketed, single stranded wire is acceptable; please refer to local code requirements.
