Service Information: Details on obtaining service and spare parts.
Accessories: List of available accessories for the pump.

Illustrations and Tables

Includes diagrams of pump components, wiring connections, and performance curves.
Tables provide detailed data on operating conditions, performance, and construction materials.

Cooling System Specifications and Recommendations:

90% of heater input power is transferred to the water supply, with the remainder lost as radiant heat.
Cooling-water must be additive-free and maintain an outlet temperature no higher than 35°C.
Water flow rate should be at least 20% higher than the calculated minimum to ensure efficiency.

Electrical Connection and Safety:

Use a suitable isolator with overcurrent trip for electrical supply connection, ensuring cables are adequately rated and protected.
Incorporate an RCCB to disconnect supply if insulation resistance is too low, and include fuses and an emergency stop button for safety.

Thermal Snap-Switches and Safety Measures:

Connect cooling-fail thermal snap-switches to the control circuit to prevent overheating due to cooling failure.

System Leak Testing and Fluid Handling:

Leak-test the system before filling with pump fluid to ensure vacuum integrity.
Handle vapour pump fluids with care, avoiding high temperatures to prevent dangerous thermal breakdown products.

Filling Procedure:

Two methods are provided for filling the pump with fluid, ensuring the fluid level is correct using a dipstick.

Maintenance Procedures for Pump Systems

1. Checking the Pump Fluid-Level

To ensure optimal operation, regularly check the fluid level in the pump boiler.

Allow the pump to cool and open it to atmospheric pressure.
Loosen the union nut, remove the dipstick and ‘O’ ring seal, and check the fluid level.

2. Inspecting and Draining Pump Fluid

If the pump's performance is unsatisfactory, inspect the fluid condition:

Allow the pump to cool and open it to atmospheric pressure.
If cold, warm the fluid by switching on the heaters for up to two minutes.

3. Cleaning and Inspecting the Pump

Regular cleaning is essential for maintaining pump efficiency:

Choose a cleaning solution suitable for the pump fluid.
Disassemble the pump following the detailed steps, ensuring all components are cleaned and inspected for damage.

4. Maintenance Schedule

Adhere to the following maintenance schedule for optimal performance:

Operation	Frequency	Section
Check the pump fluid-level	Weekly	5.4
Inspect and drain pump fluid	As required	5.5

5. Safety and Handling

Always use suitable lifting equipment to prevent injury or damage. Ensure all cleaning solutions are removed before operation to avoid fire or explosion risks.

Refer to Figure 1 which shows a part-sectional view of the 18B4B pump. The pump has: • A vertical top cone assembly (45) which incorporates the three diffusion pump stages (42, 6 and 5). • A horizontal side cone assembly (14). • A boiler (33), which forms part of the base of the pump. • A 'T' piece (38), which connects the top cone (45), the side cone (14) and the boiler (33). • A vertical backing condenser (17), which incorporates a baffle assembly (18). The diffusion pumping jet stages have top (5), second stage (6) and lower (42) vapour tubes, each of which has a jet cap (47, 44, 43). The...

1.5.1 Cooling-fail thermal snap-switches Refer to Figure 1. The pump has two cooling-fail thermal snap-switches (7, 9) on the cooling-coils. These snap-switches protect the pump against damage due to failure of the cooling-water supply. Both snap-switches have normally closed contacts that will open if the temperature of the cooling coils increases above 46 °C. The snap-switches will reset automatically when the pump cools down. You must configure the snap-switches to switch off the electrical supply to the pump heaters when the snap-switch contacts open. You must also interlock the snap-switches...
