Requirements and Recommendations for Installation
Electrical Requirements
The system is equipped with a high grade rated SJT power cord and hospital grade plug. By design, the plug is to be placed into a standard 115 volt 60 Hz outlet. Generally, contractors will provide a duplex or quadplex box that can be floor or wall mounted. For systems shipped outside of North America with 230 volt 50 Hz service, you will need to supply the correct plug per your country’s electrical code.
IMPORTANT REQUIREMENT: Due to the sensitive nature of the electrical components installed in the system, the electrical supply needs to be made to a dedicated AC circuit with an isolated ground to provide line noise rejection and computer-grade electrical current.
Pipe Junctions – Housings and Concealment
It is recommended to cover the area where the pipe stubs and connections are made to prevent them from being bumped into and to conceal them within the operatory. If a computer or monitor will be attached to the delivery system, it is advisable to have network cables, or other types of connection device cables such as USB or monitor cables, run through the same area as the plumbing to manage all the various tubing, wires and cables. Any housing type is acceptable and can even be custom made to complement the woodwork trim or cabinetry in the operatory.
For cart installations, it is recommended to have the plumbing and electrical run inside the wall between two studs (similar to a recessed washing machine connection box in households).A decorative trim panel can then be placed over the wall with cut-outs for the umbilical lines. The location in the wall should be approximately 12″ to 18″ off the floor and should be near where the cart will be placed.
Compressed Air
The system is provided with a standard dental air line for supplying compressed air to the system.
The air line is 1/4″ outside diameter (O.D.) and has a 1/8″ inside diameter (I.D.). The system also includes a combination master air supply assembly with regulator and internal air filter, and a standard angle stop with a manual shut-off valve. The angle stop has a 5/8″ compression fitting inlet to connect onto 1/2″ copper pipe. The outlet of the angle stop has a 3/8″ compression fitting to accept the connector from the master air supply. Air supplied to the system should be oil-free and regulated to a standard dental unit pressure of 75 to 80 psi. The 1/4″ air line is connected directly to the master air supply assembly.
An optional quick connect (Model 2744) can be ordered to allow easy disconnection of the air supply. This is ideal for cart type systems, allowing carts to be used in different operatories or for serviceability. The quick connect uses a Parker brand 3/8″ type which is commonly used in the dental industry for compressed air. The 3/8″ male quick connect is placed on the air line to the cart and the 3/8″ female quick connect is placed on the line to the air supply. The back end of the quick connects have reducers to adapt to the 1/4″ tubing.
Foot Control Tubing – Installation Recommendation
For carts that do not have a requirement for mobility out of the treatment room, it is recommended that conduit (pipe) of 3/4″ or larger be placed under the floor to allow the foot control tubing to run under the floor and exit out of the floor behind the base of the patient chair. This eliminates having to pull the foot control out while pulling the delivery system towards you. Excessive runs of tubing greater than 12 feet should be avoided, as there may be a lag in electronic instrument shut-off when the foot pedal is released by the operator.
Water Supply
All systems include a Dual Closed Clean Water System standard. There is no need to connect to municipal water lines. To optimize infection control, connecting to municipal water is not recommended. If this option is still desired, connection to city water can be provided by requesting a selector switch (Model 9776) to connect between city water and bottled water.
Each model also includes an air/water master valve assembly. You may request a Master Air & Water Supply Template and Schematic if connecting to city water.
Suction Connections and Piping Recommendations
ASI supplies suction line tubing made from a special grade of material that is inert to common caustic irrigants and disinfectants used in dentistry. The suction tubing has a 5/8″ inside diameter (I.D.). Included with suction packages are PVC adapters to connect the 5/8″ tubing to either 1/2″ or 3/4″ PVC pipe. If using 1/2″ copper pipe for suction, the tubing can simply be slipped over the pipe and clamped into place.
RECOMMENDATION: PVC pipe is recommended for suction plumbing lines and NOT copper, as the copper can corrode from some of the caustic irrigating and disinfectant solutions used in dentistry, such as sodium hypochlorite. Check your local building codes to see which piping materials may be used for suction lines.
For cart systems, an optional quick connect (Model 2769) is available to allow the suction hose to the cart to be disconnected. It comes with a 5/8″ barb that plugs into the receptacle half and a blank plug to seal the outlet if the hose is disconnected.
Optional Suction Quick Connection 90-2769
Optional Suction Quick Connection with Plug in Place
For systems with optional Micro Evacuation that are not connected through a Solids Trap, a separate 1/4” beige suction line will be provided. Depending on the configuration, there are a few different ways to connect this tubing. It may be connected straight to a PVC elbow with the provided adaptor, or you may need to Tee off the main suction line. Two size Tees are provided, one is for a 5/8” ID tubing, or one is for 3/4” ID tubing.
