INSTALLATION INFORMATION

Grounding reliability can only be achieved when the equipment is connected to a receptacle marked HOSPITAL ONLY or HOSPITAL GRADE.

For new installations it is recommended to follow the following guidelines:

I

Suction line from the operatories to be a minimum of 1-1/2” diameter. and must be sloped (1/4” minimum for every 10’) toward the separation tank. The suction line should not have any sharp right angle bends.

I

I

The suction line should be connected to the CAS

TM separation tank with a short run of

1-1/2” diameter. flexible tubing.

The STS

TM system can replace water ring pumps with smaller diameter piping in existing installations.

I

The drain on the base of the separation tank must be connected to an open floor drain capable of handling 10 gallons in 30 seconds. Drain pipe size 1-1/2” schedule 40.

I

I

The drain line should be a short run with a minimum slope of ¼” for every 10’ toward the drain (avoid any sharp right angle bends).

The vent line should be 2” diameter pipe for a single STS

TM and 3” diameter. pipe for a dual system. The vent should be sloped 1/4” per 10’ towards the pump. Vent line must be capable of handling vapors and liquids.

I

I

The outside vent must be protected from rain and animals.

I

A flexible air exhaust hose is provided to connect to the 2” diameter vent pipe and heat exchanger. Hose clamps are provided to secure hose to heat exchanger and pipe.

Wash-out port uses a 3/4” garden hose connection, affixed to the CAS

OPERATING INFORMATION

I

I

I

I

I

The STS

TM may be turned “ON/OFF” from a single, convenient location within the dental office using a Remote Control Panel. Remote wiring must be done by a licensed electrician in accordance with local codes.

The vacuum level is factory preset at 10 in Hg (inches of mercury). This is the reading on the gauge when all HVE’s and SE’s are CLOSED. If this setting needs to be adjusted contact your dealer to readjust the setting.

The unit is capable of running continuously. To conserve electricity, the system may be turned off when not in use.

The CAS

TM separation tank has been designed to collect the fluids evacuated during a normal operating day. If an excessive amount of fluids are collected in the CAS

TM

, the protective mechanism in the CAS

TM will interrupt the vacuum flow in order for the tank to automatically drain. This process takes approximately 30 seconds. To restore the vacuum to full operation turn OFF the power to the STS

TM for a minimum of 10 seconds and then turn back ON.

Turn the power OFF at the end of the day. This will drain collected liquids in the CAS

TM separation tank.

MAINTENANCE

Preventive Maintenance

Whenever a service technician fulfills a repair call at the customer site routine checks should also be performed to detect general overall wear, and replacement of parts should be made if necessary before a failure causes a prolonged shut-down. This preventive maintenance program will aid in dependable equipment operation and help reduce breakdown.

Initial Maintenance

The CAS

TM

uses patented technology to provide cyclonic action cleaning within the tank.

After installation, clean the vacuum lines with Clean Stream

TM

Cleaner. This is especially necessary when a new system is being installed into existing dental system piping. Using

Clean Stream

TM

Cleaner helps the STS

TM

system to remove any built up deposits in the piping system.

Daily Maintenance Recommendation

Further, to maintain the cleanliness of the CAS

TM

, including all the vacuum lines and tubing in the dental system, Air Techniques recommends that the dental office personnel be instructed to use Clean Stream

TM

Cleaner daily as part of the overall preventive maintenance program.

Yearly Maintenance

Although the CAS

TM

uses patented technology to provide cyclonic action cleaning within the tank during operation of the STS

TM

system, the tank does need to be inspected and cleaned yearly to insure proper operation. Procedures to inspect and clean the new and old style

CAS

TM

tanks are provides by the following pages. Perform the procedures corresponding to the to installed tank style to remove any solids trapped in the tank.

Maintenance-Free STS Pumps

All STS pumps are designed for maintenance-free operation. The pump features a powerful permanent split capacitor motor, with a highly reliable contactor and powerful transformer. The motor is completely water and oil-free and provides a dependable operation requiring no scheduled maintenance.

MAINTENANCE

Yearly Tank Maintenance Procedure. Refer to Figure 11 and perform the procedures to remove any solids trapped in the tank.

1. Turn OFF the power to the STS

MAINTENANCE

Over or under adjustment of the Vacuum Relief Valve can degrade overall system operation. Adjustments should only be made to keep the suction level at the factory-set 10 InHg level, which is adequate to provide optimum operation.

Vacuum Relief Valve Adjustment

The STS

TM

system vacuum level is factory set at 10 InHg (inches of Mercury) as shown by the Vacuum Gauge. This suction level is more than adequate to provide a properly sized system service for a multiple-user dental facility. Whenever the suction level varies above or below the factory set point, adjustments can be made as necessary via the Vacuum Relief

Valve. Refer to Figure 12 and adjust the system suction level by performing the following:

1. Access Vacuum Relief Valve by removing Vacuum Relief Valve Cap from the Vacuum

Connection Assembly.

2. Hold Adjusting Nut with a 7/16-inch open-end wrench.

3. Using a flat screwdriver, adjust suction level as follows: a. Increase suction by turning adjusting screw clockwise in no more than 1/4 increments.

b. Decrease suction by turning adjusting screw counterclockwise in no more than 1/4 increments.

Vacuum Relief Valve Cleaning

A dirty or clogged Vacuum Relief Valve degrades the STS

TM

system suction level. Clean the Vacuum Relief Valve by removing Vacuum Relief Valve Cap and carefully pulling the valve from the Vacuum Connection Assembly. Blow out accumulated solid deposits using clean low pressure compressed air.
