WATERLINE MAINTENANCE

Dental unit waterlines, reservoir water bottles, and water distillers/processors contain bacteria (unless sterile water is used), measured in colony-forming units per milliliter (CFU/mL) of heterotrophic water bacteria. The bacteria, if not controlled, can reach elevated levels and form into biofilms on the walls of the plastic tubing that can be resistant to microbial treatment. The CDC recommends using procedural water in routine dentistry that does not exceed 500 CFU/mL. To achieve these levels, ForestTM suggests an action level of 250 CFU/mL to limit microbial proliferation. By closely following both the Forest and water treatment product manufacturer’s instructions for use (IFU), it is possible to maintain procedural water within CDC guidelines.

WARNING:
Refer to Forest Dental Unit Water Line Maintenance Operator’s Guide for monitoring and disinfection of your dental unit waterlines and dental unit reservoir bottle as well as the monitoring of source water.

SELF-CONTAINED CLEAN WATER SYSTEM WITH QUICK-DISCONNECT BOTTLE

WARNING:
Refer to Forest Operatory Equipment Asepsis Operator’s Guide for infection control procedures. Self-contained water systems do not control bacteria levels or prevent biofilm from accumulating in the dental unit water lines. This can only be achieved by flushing, monitoring and maintaining the dental unit water lines according to Forest Dental Unit Water Line Maintenance Operator’s Guide. Dental units do not deliver sterile water. Sterile solutions must be used as a coolant/irrigant for all surgical procedures from an isolated source (such as a sterile bulb syringe or sterile tubing that bypasses DUWL) as recommended by the CDC. Isolated water sources (as opposed to city water hook-up) are highly recommended to allow full control of the source and quality of water circulating through the dental unit waterline.

The self-contained water system allows you to isolate your practice from the municipal water supply. The self-contained water system uses a pressurized bottle to supply water to the dental unit giving you full control of the source and quality of the water.

• STEP 1: Ensure that the dental unit is turned off. Fill the water bottle from a known potable source with the adapter attached, then install on the manifold by turning clockwise (FIG. 1).

• STEP 2: Turn the dental unit on and check for leakage at the bottle. If air or water leakage is observed, turn the dental unit off and allow several seconds for air pressure to be released from the bottle.
  WARNING : Never attempt to remove the bottle when it is pressurized.

• STEP 3: Remove bottle and install a new bottle with adapter.

• STEP 4: Turn the dental unit on and check for leakage at the bottle as previously described.

WARNING:
Only use water bottles supplied by Forest. Do not use soft drink bottles that are thin-walled and may rupture when under pressure. When using self-contained water systems, all plastic bottles should be inspected for damage prior to every use. If a bottle appears to be damaged in any manner, it should be replaced. When filling the reservoir water bottle, leave an air gap at the top of the bottle to allow the bottle to pressurize. Do not attempt to adjust the water bottle pressure. Bottle pressure is factory pre-set at 40 PSI Pressurizing the water bottle over 40 PSI may cause the bottle to rupture.

QUICK-DISCONNECT BOTTLE

NOTE : This quick-disconnect bottle allows for a quick and easy way to change water bottles. Simply push up and turn clockwise to install the bottle. Turn counterclockwise to remove the bottle.

HANDPIECE EXHAUST

Located inside every control head (Euro: Canister underneath control head) is an exhaust canister. The sole purpose is to trap excess oil to prevent it from spraying the inside of your control head while exhausting your handpieces (FIG. 6). Before exhausting the handpieces, make sure that there is a 2” x 2” gauze pad inside the canister. This is to collect and absorb the excess oil. To prevent handpiece lubrication from contaminating the interior of the control head, make certain the drip exhaust lines remain in the canister.

EXHAUST CANISTER

NOTE : Forest TM recommends changing the gauze biweekly or when visibly saturated.

ASSISTANT’S INSTRUMENTATION & VACUUM
