Design

The external oil filter consists of a shell with an end cover welded on to the end. At the other end,

the filter can be inspected or extracted through a flange connection. Nozzles are welded in the

shell and dished end cover.

Product description

The oil must pass the filter cartridge from the inside out. This way dirt will accumulate on the in-

side of the filter cartridge and thus not fall into the filter housing when replacing the filter

cartridge.

Application

The external oil filter is mounted in the oil pipe between the oil separator, oil cooler and the com-

pressor. The external oil filter may be constructed with either one or two parallel filters.

Shipping

The oil filter must be delivered blanked off and primed. The primer is not intended for outdoor

storage. If the oil filter is not to be placed in immediate service, take precautions to prevent rust-

ing or contamination.

The oil filter must only be lifted when empty and must not be subject to strokes or bumps during

transport. When lifting the oil filter before it is built into the unit, straps around the shell must be

used. Please note that the weight appears from the technical data.

When the oil filter is built together with the unit, a shipping description can be made.

Installation

The site and personal protection must be in accordance with EN 378-3 or national requirements.

Immediately upon receipt, the oil filter must be checked for damage occurred during transport. If

the oil filter is damaged, it must not be installed.

The oil filter must be placed in such a way that there is enough space for inspection, maintenance,

escape and emergency.

Foundations must be sufficiently robust so that they provide permanent support without settling

and absorb any normal vibrations from outside causes.

Blanked off branches to be cut off at the cutting groove depending on metal thickness on adjoin-

ing tubes. It must be ensured that dirt or other unknown elements do not get into the oil filter dur-

ing installation. Do not remove protective plugs and covers until immediately before installation.

The entire system should be clean before starting operation. Tube connections must be fitted in

such a way that tensions in the oil filter during test, operation and standstill do not exceed the al-

lowable values. Vibrations must be minimised possibly by means of vibration dampers.

Aside from branch connections, welding must not be carried out on the oil filter. The oil filter must

be secured against exceeding of the allowable pressures and temperatures. The outer surfaces

must have a top coat which is suitable for the surrounding environment to avoid corrosion.

Before start, it must be ensured that all connections are tight.

Safety equipment

Before the oil filter is put into service, it must be provided with safety equipment.

The manufacturer of the refrigeration plant is responsible for the equipment, as the safety equip-

ment is not included in the oil filter supply.

Start-up and operation

To avoid accidents or personal injury, the person responsible for the plant must ensure that the

operating staff is duly trained and instructed before the refrigeration plant is started. The training

should be based on the unit instruction manuals and should include instructions in construction,

supervision, operation and maintenance of the system as well as handling of used refrigerant.

Evacuation and charging with refrigerant must be carried out according to the unit description for

use.

Before operation, the refrigeration plant must be leak tested and inspected by a competent per-

son. Local safety and health regulations must be observed.

Bolted connections

Normal relaxing of the gasketed joints may occur in the interval between testing at the manufac-

turer’s and installation on site. Therefore, all external bolted joints may require retightening after

installation and, if necessary, once again when the vessel has reached its operating temperature.

Note that retightening must never be performed during operation.

It is important that all bolted joints are tightened evenly and in a diametrically staggered pattern.

All bolts must be tightened to the same torque using a torque wrench.

Maintenance

The oil filter should be inspected at the inspection intervals stated in the compressor specification.

Inspection must only be carried out by competent personnel.

Operating experience will show how often the oil filter needs to be inspected/checked. It depends

on the operating conditions. Johnson Controls Denmark recommends that the oil filter is in-

spected at monthly intervals during the running-in period.

After a running-in period of six months, a maintenance plan must be made. As a minimum John-

son Controls Denmark recommends inspection every third month.

Connections must not be dismounted or tightened when the equipment is under pressure. Peri-

odic inspection during the lifetime of the oil filter must meet the requirements in national instruc-

tions or EN 378-2.

Visual inspection of connections, outer surfaces, bases, vibration damper and safety

equipment

If corrosion, erosion or other weaknesses in the oil filter are found, the oil filter must be scrapped

or inspected by a competent third party, who will grant the necessary permission to continue us-

ing the oil filter. If a repair is requested, this will be carried out by approved personnel in coopera-

tion with a competent third party and Johnson Controls Denmark.

Disassembly for inspection or cleaning

Before disassembly, the user must make sure that the oil filter has been depressurised, vented

and drained, neutralised and/or purged of hazardous material.

Gasket connections

The gasket and gasket surface should be thoroughly cleaned and free of scratches and other de-

fects. The gasket should be properly positioned before attempting to retighten the bolts. When an

oil filter is dismantled for any cause, it must be reassembled with new gaskets. This will prevent

further leaks and/or damage to the gasket seating surface of the oil filter.

Spare parts and replacement parts

Environmentally correct removal

The oil filter does not contain environmentally damaging material, such as asbestos, mercury or

heavy metals.

All parts of the oil filter can be reused after being scrapped.

• Refrigerant must be drained before destruction

• All steel materials can be used again after remelting

• During the remelting process, coating will disappear without damaging the environment.
