Vatech’s manufacturer requirement is that all pre-installation site checks must be done prior to any Vatech device installs, during any anual inspection or troublehsooting/repair to ensure proper power requirements are met and maintained.
Power Specifications: All Hard Wired Units
The following is a brief overview of the power requirements that MUST be checked and/or resolved prior to the installation or service repair of ANY Vatech product
Verify and Run a Dedicated: Medical Grade to the Principal Pannel* if the lines are not already connected to the principal pannel.
(Typically seen between 115v ~ 125v at wall with 120v medium)
(0.00v preferred but not to exceed .2v)
If the Neutral / Ground 'Voltage & Noise exceeds the recommendation:
1.) Voltage/Surge Protection:
'AVR' or Automatic Voltage Regulator should be used for Voltage / Surge Protection.
TripLite LC1200 Or higher/Similiar devices*
These devices typically will help with voltage, brown outs and things of that nature but should not be confused as a 'Battery Backup or UPS by their more common name" as Battery Backups can cause damage to the device.
2.) Legacy Amperage Protection:
Checking Power & Neutrual To Ground proceedure:
First verify the outlet is properly wired by using Outlet tester, simply plug it in and follow the Key on the tester. Normally all testers are the same, both amber lights and red off indicates a good wiring connection. Any other combination will indicate the referenced wiring problem as specified on the tester's key diagram.
A tester can be acquired at most hardware, electric supply stores, walmart or other like locations. In the event you do not have access to a tester, you can use your volt meter to check however is less accurate due to human error.
You must measure neutral-to-ground or hot-to-ground voltage. If the neutral-to-ground is 120V and the hot-to-ground is a few volts or less, then the hot and neutral wires are reversed
Next we will need to check for the proper voltage levels first by checking Hot and Neutral, Confirming the power is with in 110 specifications +/- 10%.
Next check the Neutral to Ground for any voltage noise being fed into the ground. On a dedicated outlet the target voltage reading should be .000 however in some cases less than .2 volts may be acceptable. Anything above .2 volt should be checked for proper dedication and noise interference due to faulty wiring or other noise being fed into the environment. This can be anything from internally in the office or power supply from the electric company. It will be up to a qualified electrician to determine the root issue.
In some cases a dedicated/isolated ground may be used to clear up stray voltage noise and bypass the electric box receiving the noise.
Vatech America will not be liable for damages to the machine under the warranty terms and conditions due to non-dedicated power connections, improper voltage, noise, or faulty grounding environment.
It is the sole responsibility of the purchaser to confirm that these requirements are met prior to the installation of any Vatech device. If the specifications are not met, please insure that the issues are resolved before connecting or continuing to use with defective non-compliant power.We also recommend requesting the office’s electrician report on their findings and a confirmation of repair detailing what steps were taken to resolve the issue(s).
