1/8" MIP Angle Valve Installation

The plumber supplies the water line and installs a 1/2"brass gate valve on the water supply line. Connect the1/4" nylon tubing and slide the nut and brass ferruleover the tubing. Push the tubing in the valve as far aspossible. Make sure the tapered end of the ferrule isfacing the end of the tubing and tighten the nut.

Vacuum Line

Vacuum lines must be installed by a local plumberaccording to local building codes. All vacuum linesand risers are recommended to be IPS, PVC, SCH.40. Type “M” copper should be used if local codedoes not allow the use of PVC.

Care should be taken to slope the lines 1" for every20' of run toward the vacuum pump(s). This allowswaste and liquids to flow with gravity, contributing tothe efficiency of the vacuum system.

Make all connections using long radius sweep fittings.To promote unrestricted flow of air and waste liquids

through the vacuum lines, directional flow connec-tions should be used.

Using 45º elbows for turns or avoiding obstructions isbest; however, do not make a trap in the line, doing sowill decrease the efficiency of the system.

All elbows and tees should be sized for the main lineand sized down with bushing reducers to accommo-date smaller lines.

Avoid sagging lines, which cause the formation oftraps in the system and prevent good air and wasteliquid flow.

Connect the evacuation system to the vacuum lineusing the hose and fittings supplied in the installa-tion kit.

Water Supply Line

Vacuum Line

The water going to the unit acts as a pump sealantand cooling agent. When the vacuum pump is inoperation, the water supply must be on at all times.The plumber supplies and installs a 1/2" gate valveon the water supply line. Connect the 3/8" nylontubing and fittings, which are supplied with the unit,as illustrated.

Vacuum lines must be installed by a local plumberaccording to local building codes. All vacuum linesand risers are recommended to be IPS, PVC, SCH.40. Type “M” copper should be used if local codedoes not allow the use of PVC.

Care should be taken to slope the lines 1" for every20' of run toward the vacuum pump(s). This allowswaste and liquids to flow with gravity, contributing tothe efficiency of the vacuum system.

Make all connections using long radius sweep fittings.To promote unrestricted flow of air and waste liquidsthrough the vacuum lines, directional flow connec-tions should be used.

Using 45º elbows for turns or avoiding obstructions isbest; however, do not make a trap in the line, doing sowill decrease the efficiency of the system.

All elbows and tees should be sized for the main lineand sized down with bushing reducers to accommo-date smaller lines.

Avoid sagging lines, which cause the formation oftraps in the system and prevent good air and wasteliquid flow.

Connect the evacuation system to the vacuum lineusing the hose and fittings supplied in the installationkit. The vacuum line can be installed from the right orleft side of the cabinet.
