1Introduction

1.1 Scope and definitions

This manual provides installation, operation and maintenance instructions for the Edwards EMF Gas Ballast Oil Drain

Kit for RV3to RV12 Pumps. You must use the Oil Drain Kit as specified in this manual. Read this manual before you

install and operate the Oil Drain Kit.

1.2 Description

Note: In normal operation, oil will not be visible in the sight-glasses of the oil mist filter.

The Oil Drain Kit is designed for use with an RV3, RV5, RV8 or RV12 pump (fitted with an EMF oil mist filter) which

operates continuously with gas ballast switched on. You cannot use the Oil Drain Kit if you want to introduce a purge

gas into the RV pump. If you want to introduce a purge gas into the RV pump, you must fit a Gas Ballast Adaptor to

the pump (refer to the RV pump instruction manual) and oil cannot be returned from the pump.

When fitted, the Oil Drain Kit continususly returns oil trapped in the oil mist filter to the pump. This reduces oil loss

from the pump and minimises the need to check the pump oil-level and to refill the pump with oil.

At high inlet pressures (above 200 mbar, 2 x 104Pa), the Oil Drain Kit will not work correctly. If you want to return

oil to the pump when the pump is operated at high inlet pressures, contact your supplier or Edwards for advice.

The Oil Drain Kit is not suitable for use with an RV pump which is used in hazardous processes.

2 Installation

2.1 Unpack and Inspect

Remove all packaging materials and protective covers and check the Oil Drain Kit. If the Oil Drain Kit is damaged,

notify your supplier and the carrier in writing within three days. You must state the Item Number of the Oil Drain Kit

together with your order number and your supplier’s invoice number. Return all packaging materials for inspection.

Do not use the Oil Drain Kit if it is damaged.

Check that your package contains the items listed in Table 1. If any tiem is missing, notify your supplier in writing

within three days.

If the Oil Drain Kit is not used immediately, replace the protective covers. Store the Oil Drain Kit in suitable

conditions, as described in Section 4.1.

2.2 Fit the Oil Drain Kit

Where necessary, refer to the instruction manuals supplied with your pump and oil mist filter when you fit the Oil

Drain Kit.

1. Switch off the pump and allow it to cool to a safe temperature. Isolate the pump from the electrical supply, so

that it cannot be operated accidentally.

2. Remove the drain-plug from the oil mist filter and drain the oil from the oil mist filter. Retain the drain-plug for

future use.

3. Refer to Figure 1. Fit the drain adaptor (8) to the oil mist filter (1).

4. Turn the gas ballast control on the pump to the high flow position (position II). Push the control down (against

the spring), turn the control anticlockwise to release it and remove the control from the pump. Leave the spring

in position in the gas ballast inlet.

5. Refer to Figure 3. Fit the two ‘O’ rings (6, 7) to the oil return assembly.

6. Refer to Figure 1. If you have an RV3 or RV5 pump, lift the handle. Fit the oil return assembly (5) to the gas

ballast inlet on the pump, push the assembly down (against the spring) and turn the adaptor clockwise to secure

it on the pump. When the oil return assembly is correctly secured to the pump, the nozzle (4) should be over the

gas ballast ‘0’ position marked on the top of the pump:see detail B.

7. Cut a suitable length from the flexible oil-return tube. The routing of the tube (3) must be approximately as

shown in Figure 1. When fitted, the tube must not be taut and there must be no tight bends in the tube. Ensure

that the ends of the oil-return tube are free of burrs and that they are squarely cut(that is, the cut faces are at

a right-angle to the length of the tube).

8. Fit the restrictor (7) into one end of the tube as shown in Figure 1, then fit the end of the tube (3) to the drain

adaptor (8) on the oil mist filter.

9. Fit the other end of the tube to the nozzle (4) on the oil return assembly (5).

10. Use the hose clips (2) to secure the ends of the flexible oil return tube (3).

11. Reconnect the pump to the electrical supply.

2.3 Select the gas ballast flow rate (optional)

Note: If re quired, use the pro cedure be low to change the gas bal last flow rate af ter you have used the Oil

Drain Kit; you must switch off the pump, al low it to cool and iso late it from the elec trical sup ply be fore

you use the fol lowing pro cedure.

The Oil Drain Kit is supplied configured so that the gas ballast flow rate is equivalent to that with the gas ballast

control on the pump in position ‘II’. If required, you can adjust the gas ballast flow rate; use the following procedure:

1. Refer to Figure 2. Undo and remove the three screws (1) which secure the restrictor plate (5); do not dismantle

the assembly.

2. The restrictor plate (5) has circular indentations (2 and 3); the position of these indentations with respect to the

indentation (4) on the oil return assembly identifies the gas ballast flow setting. Turn the restrictor plate to the

required position:

To select no gas ballast flow (equivalent to the gas ballast control on the pump in position ‘0’), turn the

restrictor plate so that none of the indentations (2 and 3) are aligned with the indentation (4) on the oil

return assembly.

To select low gas ballast flow (equivalent to the gas ballast control on the pump in position ‘I’), turn the

restrictor plate so that the single indentation (2) is aligned with the indentation (4) on the oil return

assembly.

To select high gas ballast flow (equivalent to the gas ballast control on the pump in position ‘II’), turn the

restrictor plate so that the two indentations (3) are aligned with the indentation (4) on the oil return

assembly.
