● Fill the gear and bearing chambers with lubricant only once the final installation posi- tion is reached. Pfeiffer Vacuum recommends keeping the transport packaging and original protective cov- General information regarding safe transport 1. Observe weight specified on the rating plate.
– In rooms with humid or aggressive atmospheres, seal the roots pump airtight in a plastic bag, together with a drying agent. – After a storage period of 2 years, Pfeiffer Vacuum recommends changing the lubricant. The best corrosion protection for the roots pump is achieved by evacuating and then filling the suction chamber with nitrogen.
Pfeiffer Vacuum are excluded. ► Use approved lubricant only. ► Use other application-specific lubricant only after consultation with Pfeiffer Vacuum. The type of lubricant specified for the gear and bearing chambers, and the fill quantity for the entire roots pump are shown on the rating plate.

Installation 5.5 Connecting the fore-vacuum side WARNING Risk of crushing from rotating parts Fingers and hands may be caught by rotating pistons within the connection flange. This results in se- vere injuries. ► Keep limbs out of the reach of the roots pump. CAUTION Danger of injury from bursting as a result of high pressure in the exhaust line Faulty or inadequate exhaust pipes lead to dangerous situations, e.g., increased exhaust pressure.
► Route the mains connection in accordance with locally applicable provisions. ► Always provide a suitable mains fuse to protect the motor and supply cable in the event of a fault. – Pfeiffer Vacuum recommends the circuit breaker type "K" with slow tripping characteristic. NOTICE Motor damage from overheating Limited motor fan cooling capacity, caused by low speeds, causes the motor to overheat.
Installation 5.6.2 Checking the direction of rotation Fig. 8: Check of direction of rotation Procedure When switching on for the first time, check the roots pump direction of rotation. 1. Switch the vacuum pump on briefly (2 to 3 seconds) – The motor and coupling must rotate clockwise (see directional arrow on housing cover). 2.

3. Set the desired quantity of sealing gas on the dosing valve of the inferential meter. Example for Okta 1000 G with, e.g., 50 hPa intake pressure and 8 % sealing gas content = (1284 × 50 × 0.08)/1013 = = 5.07 Nm...
Operation 4. Make sure that you do not vent the vacuum chambers through the vacuum pump. 5. Switch off the process- and pump-specific media supply (e.g. the sealing gas supply). Procedure with contaminated medium With media that heavily contaminate the suction chamber, flush the suction chamber with air or nitrogen at the end of the process.
You can carry out maintenance work at Maintenance Level 1 yourself. We recommend Pfeiffer Vacuum Service for carrying out maintenance work of Maintenance Level 2 and Maintenance Level 3 (revision). If the required intervals listed below are exceeded, or if mainte- nance work is carried out improperly, no warranty or liability claims are accepted on the part of Pfeiffer Vacuum.

The usable life may deviate from the reference value specified depending on thermic and chemical loads, or due to penetrating process media in gear and bearing chambers. Safety data sheets You can obtain the safety data sheets for lubricants from Pfeiffer Vacuum on request, or from the Pfeiffer Vacuum Download Center.
A decreasing oil level, with no leaked oil visible below the roots pump, is due to a worn inner radial shaft seal ring. ► Should this occur, arrange for maintenance to be carried out by Pfeiffer Vacuum Service, during which all 3 radial shaft seal rings are generally replaced.
Maintenance NOTICE Property damage from incorrect cleaning procedure Flushing fluid and process media that enters the bearing and oil chambers will stick. ► During the cleaning processes, always protect all bearings with sealing gas in order to prevent a contamination of the lubricant and bearing chambers. The clearance between pistons and housing are within a tenth of a centimeter range.
Maintenance Install the overflow valve 1. Mount the ball, compression piece, and spring. 2. Lock the thread on the pressure screw with Loctite 243. 3. Screw in the pressure screw. 4. Locate the valve plate in the overflow channel. 5. Install the O-ring in the appropriate groove. 6.
► Attach the motor to the lifting gear with the eye bolt and pull the motor horizontally away from the vacuum pump. ► Use jacking bolts and guide pins.
