Troubleshooting

Vacuum System Operation

Operatory waste (air, solids and liquids) is pulled into the separator through the inlet hose by the rotary claw pump in the vacuum base unit.

Air is separated from liquids and solids. Air then flows into the pump and out through the exhaust hose.

Fresh air is pumped in through the Vacuum Relief Valve to the pump and out through the exhaust. (When ports are opened in the operatories the

VRV closes to compensate.)

The check valve connected below the drain port allows the unit to drain liquids and solids upon removal of vacuum from the chamber when the pump / motor shuts off.

The fan(s), hour meter and vacuum pump start to run when power is supplied by the wall switch. The fan(s) and hour meter then begin to cycle with the vacuum pump / motor. The float switches control the pump motor by a 24 vac relay via motor contactor.

The upper and lower reed switch floats interact as a latching circuit with the internal relay to release upon drain below the bottom float.

Electrical System for Accessory - Liquid Evacuation Pump

The Liquid Evacuation Pump is an optional accessory for the PowerVac ® .

• 115 VAC is applied to the 115V / 24V Transformer energizing it.

• 24 VAC is applied from one side of the Transformer to the J3 plug.

• When the water level reaches the Bottom float switch, K3 relay contact closes.

• When the water level reaches the Middle float switch, K2 & K4 relay contact close.

Power is supplied to J8 and J9 terminals, energizing the Liquid Evacuation Pump.

NOTE:

The Liquid Evacuation Pump will continue to run until the water level drops below the Bottom float switch, opening K3 & K4 relay contacts.

Refer To:

Evacuation Pump Will Not Run ............. A-12

Pump Runs But Will Not Pump ............. A-13

Pump tripping Thermal Overload .......... A-14

Optional Liquid Evac Pump Must use a Three Float Assembly

If the Top float closes, K1 relay contacts close, and its LED is on, a problem is occurring with the system.

Check for a restriction in the lines, pump not functioning, or PC board problem.

Check Valve

Location and Function

The Check Valve located in the drain allows the separator to drain upon removal of vacuum pressure. When the pump is not running, the valve opens, allowing liquids to drain. If the pump is running the valve closes to keep air in the drain from back flushing into the system.

Each vacuum pump in a multiple pump installation requires a check valve to be installed into the intake line.

This prevents loss of suction pressure when one pump in the system is turned off. If no check valve is present, flow will be allowed through he "off" pump, creating a loss suction of the rest of the system.

Vacuum Pressure keeps Valve

Closed when Pump is Running

Float Assembly

Location and Function

The Float Assembly contains three Float (Reed) Switches mounted on a bracket at different intervals.

The Reed Switch has contacts that remain open until the liquid in the separator rises, causing the float to rise until the magnet contacts the Reed Switch.

When the magnet contacts the Reed Switch, the open contacts inside the reed close.

When the top float switch closes, the fan, hour meter and vacuum pump stop running until the bottom float opens and the cycle starts again.

The upper and lower floats interact as a latching circuit with the internal relay to release upon drain below the bottom float. The magnet in the float is to activate the reed switch within the stem.

If the PowerVac

® has a Liquid Evacuation Pump (Accessory) installed, it begins running when the middle float switch closes, avoiding the vacuum pump shut-off that would occur if the liquid level closed the top switch.

Earlier Versions had Three Reed Switch Floats. The Middle Float was for the Liquid Evac Pump Option. If You Have a Liquid Evac

Pump Connected to the PowerVac you Must Replace Float With a

Three Reed Switch Float Assembly. If There is No Evac Pump

Connected to the PowerVac, You can Replace the Float With a Two

Reed Switch Float Assembly.

Door Limit Switch &

PowerVac

®

Circuit Breaker

(ON/OFF Switch)

Location & Function

With facility power (230 VAC) supplied to the system....

The transformer continuously supplies 24 VAC to the normally-open door limit switch.

With the front access cover in place...

The plastic bumper on the top right side of the access cover, trips the door limit switch causing it to close.

When the limit switch is closed, 24 VAC flows thru the switch to the PowerVac ® circuit breaker (ON / OFF Switch). With the circuit breaker switch ON, current is supplied to the remote wall switch (if applicable).

Note:

If the facility does not have a remote wall switch, the PowerVac

®

circuit breaker serves as the ON/OFF switch for the system.

When the front access cover is removed...

The door limit switch opens and stops current flow to the

PowerVac

®

circuit breaker. This is a safety feature that prevents the system from operating with the cover removed.

Frequently Answers and Questions

What is the recommended vacuum pressure range for the PowerVac system?
The recommended vacuum pressure range for the PowerVac system is from 10" to 18" Hg. The valve is preset at the factory for 12" Hg.
Where is the Vacuum Relief Valve located on the PowerVac system?
The Vacuum Relief Valve is located on top of the separator tank in the 'T' Fitting on Single Models and in the center of the mounted 'T' assembly on the Twin Models.
How do I adjust the vacuum pressure on the PowerVac system?
To adjust the vacuum pressure, you will need to adjust the center mounted screw inside the valve. Each full clockwise turn increases the vacuum level by approximately 2 inch Hg.
What should I do if the vacuum pressure is low on the PowerVac system?
If the vacuum pressure is low, check for leaks or open operatory lines.
What should I do if the vacuum pump is not running?
Check the float switch system to make sure it is working properly. Also, check the fuse, relay, and contactor to ensure they are not faulty.
How do I replace the belt on the PowerVac system?
Disconnect power to the system. Remove the front cover. Slightly push up on the tension arm and remove the belt. To install a new belt, slightly push up on the tension arm and install the new belt. Replace the front cover and reconnect power.
