    1 Safety Information

    Important: Do not operate this equipment until the safety information and instructions in this user guide have been read and understood by all

    personnel concerned.

    Only competent personnel trained, qualified, and approved by Ingersoll Rand should perform installation, commissioning, service and repair


    Use of the equipment in a manner not specified within this user guide may result in an unplanned release of pressure, which may cause serious

    personal injury or damage.

    When handling, installing or operating this equipment, personnel must employ safe engineering practices and observe all related regulations,

    health & safety procedures, and legal requirements for safety.

    Ensure that the equipment is depressurised and electrically isolated, prior to carrying out any of the scheduled maintenance instructions

    specified within this user guide.

    Most accidents that occur during the operation and maintenance of machinery are the result of failure to observe basic safety rules and

    procedures. Accidents can be avoided by recognising that any machinery is potentially hazardous.

    Ingersoll Randcan not anticipate every possible circumstance which may represent a potential hazard. The warnings in this manual cover the

    most known potential hazards, but by definition can not be all-inclusive. If the user employs an operating procedure, item of equipment or a

    method of working which is not specifically recommended by Ingersoll Randthe user must ensure that the equipment will not be damaged or

    become hazardous to persons or property.

    1.1 Markings and Symbols

    The following markings and international symbols are used on the equipment and within this user guide:

    1.2 Hazardous Substances

    The chambers of the dryer are filled with DRYFIL desiccant material. This is a powerful desiccant and will dry out the atmosphere, eyes, nose,

    and mouth.

    If the desiccant comes into contact with the eyes or skin, wash the affected area with copious amounts of water.

    DRYFIL may contain some dust therefore an orinasal dust respirator should be worn when handling the equipment. Adequate ventilation should

    be provided when working with desiccant.

    The desiccant is classified as non-hazardous for transportation.

    DRYFIL will evolve heat on contact with moisture and may generate pressure in a confined space. DRYFIL should therefore be stored in a dry

    place in its original packaging.

    DRYFIL is non-flammable. Any fire should be fought by means appropriate to the material causing the fire.

    DRYFIL should be disposed of into a licensed land fill site.

    Caution, Read the User Guide.Highlights actions or procedures which, if notperformed correctly, could lead to electric shock.

    2 Description

    Ingersoll Randdesiccant dryers are designed to remove moisture vapour from compressed air. Providing pressure dewpoints of -40C (-40F)or -70C (-100F) at specified conditions.

    The dryers comprise of extruded aluminium columns. Each column contains twin chambers filled with desiccant material that dries the

    compressed air as it passes through. One chamber is operational (drying), whilst the opposite chamber is regenerating by Pressure SwingAdsorption (PSA).

    Pressure Swing Adsorption (PSA)

    A small amount of the dried compressed air is used to regenerate the spent desiccant bed. Dried air at line pressure is expanded to atmospheric

    pressure through the regenerating column.

    Energy Management System (EMS) - optional

    If EMS is fitted, this will adjust the dryer's cycle in line with the moisture loading placed upon it, by constantly monitoring the processed air

    moisture content. Also available as a retrofit to all dryer models.

    2.1 Technical Specification

    This specification is valid when the equipment is located, installed, operated, and maintained as specified within this user guide.

    Stated flows are for operation at 7 bar g (102 psi g) with reference to 20C (68F), 1 bar (a) (14.5 psi), 0% relative humidity. For flows at other

    conditions, apply the correction factors shown..

    Installation & CommissioningEN

    3 Installation & Commissioning

    3.1 Recommended system layout

    The dryer should be installed with the correct pre-filtration and condensate management equipment to meet both the specification and local

    environmental requirements.

    Referring to diagram A4 in Annex A, the following equipment is recommended to meet these requirements:

    3.2 Locating the equipment

    Identify a suitable location for the equipment taking into consideration the minimum space requirements for maintenance and lifting equipment.

    When considering the final location of the equipment take into account the noise generated when in use.

    The dryer can be free standing or secured to the floor via the fastener points provided in the base..

    3.3 Mechanical Installation

    Once the dryer has been located into position install the piping and filtration for connection to the inlet and outlet manifold. HE grade filter is

    required at the dryer inlet and a DP grade filter at the outlet as shown in diagram A5 of Annex A.

    Ensure that each filter condensate drain is suitably piped away and any effluent is disposed of in accordance with local regulations.

    The Energy Management System (EMS) system requires a sampling point to be inserted into the piping between the DP grade outlet filter and

    the isolation valve as shown in diagram A5. This sampling point should be linked to the 4mm push in connector of the EMS system using P.T.F.E

    tubing.It is important
