Page 3: Introduction
Important The refrigerant available on the C series of Compressed Air Dryers is Refrigerant R134a or Refrigerant R407C. It is imperative that refrigerants are not mixed. A label is fixed to each compressor, which identifies the refrigerant being used within the unit, and that refrigerant ONLY should be used in the dryer. R134a & R407C are ozone benign refrigerants and meet the requirements of the revised “Montreal Protocol”. -
Page 4: Health And Safety
Health and Safety Due regard shall be given to observing safe procedures when working with or on the equipment. It is the responsibility of the Installer / Operator / Customer to ensure that the “Health and Safety at Work Act (1974)” and Normal Safe Working Procedures are adhered to at all times. -

Refrigerant Safety Data Reactivity Data Stability Unstable Stable Incompatibility (Materials and Conditions to Avoid) May react violently with sodium, potassium, barium or other alkali or alkaline earth materials. Magnesium and alloys containing more than 2% magnesium. All finely divided metals. Hazardous Decomposition Products Halogen acids formed by thermal decomposition. - Page 7 Health Hazard Data and First Aid Short term effects of over exposure when: In contact with skin: Liquid splashes may cause freeze burns. No information found on irritancy or sensitisation. There is no known hazard due to absorption through the skin. In contact with eyes: Liquid splashes or vapour spray may result in freezing of tissue or eye fluids.
- Page 8 Installation - General Storage The equipment should be stored in a secure frost free area with a maximum ambient of 55°C and maximum humidity of 90% non-condensing. Unpacking Carefully remove the unit from its packing and examine it for obvious defects or damage including: ...

Page 9: Installation - Electrical
The C series Dryers require a 220/240 Volt 1 phase and neutral 50-60 Hz supply. A flying lead is installed on the dryer for convenience. The cable core colours are: Brown Live Blue Neutral Green / Yellow Earth If the unit is connected to a junction box, receiving its supply from another source (e.g., auxiliary contacts of a main starter, or a relay), then it is important that electrical protection is provided by means of a suitably rated H.R.C. -

Electrical Description Description of Components "ON / OFF" Switch This switches the live side of the power supply to the circuit. All models are fitted with a rotary type cam switch. Compressor (complete with control box) The compressor is a single phase type and incorporates a "start" circuit to avoid risk of a stalled motor on start- General The air cooled condenser fan will run under the control of the controller sensing the temperature in the compressor discharge line. -

Page 26: Control Of Refrigerant Discharge
Control of Refrigerant Discharge By international agreement, the worldwide use of certain refrigerants will be reduced in stages. To this end, listed below are suggestions on how refrigeration engineers can contribute by the discontinuing of releasing any refrigerant gas to the atmosphere. Release of refrigerant to the atmosphere is an offence under Section 33 of the Environmental Protection Act 1990. -
Page 27: Routine Maintenance
It is not normally necessary to open the refrigerant circuit. If a problem is suspected it is strongly recommended that unit maintenance or repair is undertaken by a CITY & GUILDS 2078 (or equivalent) COMPETENT REFRIGERATION ENGINEER. A City and Guilds 2078 (or equivalent) certificate will soon be mandatory. Daily ... -
Page 28: Fault Finding
Fault Finding The following fault finding chart relates various symptoms and faults of the refrigeration system. Before attempting to identify a refrigeration system fault it must first be established that the DESIGN CONDITIONS to the compressed air system are being met i.e. flow, pressure and temperature. Excessive overload will be caused by: Excessive compressed air inlet temperature. - Page 29 PROBLEM CAUSE Compressed air flow rate too high. Excessive drop in compressed Condensate is Frozen. air pressure. Exchanger Tubes soiled by impurities in the compressed air. The condensate has frozen and blocked the passage as Compressed the probe is incorrectly air does not positioned.
- Page 30 Fault Finding continued PROBLEM CAUSE Fan motor stop working High pressure switch stop working and The room temperature is too have to high control by manual There’s circulate hot air in the room causes from wrong installation The fins of refine unit were dirty.
