. Any work done to the Compressed Air Dryer involving entry into the control panel, fitting gauges, adjusting controls, charging the system, evacuating the system or opening the system in any way, must be carried out by a FULLY QUALIFIED REFRIGERATION ENGINEER. A City and Guilds 2078 or equivalent certificate is strongly advised and will soon be mandatory. Description of Operation The saturated compressed air enters the evaporator and is pre-cooled by the outgoing cooler air. The internal refrig

Corrosion Air cooled units are designed for operation in normal ambient air. Any corrosive agent in the air such as ammonia, sea water spray etc. will cause corrosion and would require special protective measures. Corrosion can result in release of pressure and refrigerant. 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 / Ye

It is not teratogenic in rats or rabbits. Short-term screening tests for carcinogenicity have proved negative. No long-term effects were noted when administered by gavage to rats at a dose of 300 mg/kg/day for one year and the rats held for the remainder of their life span. Occupational Exposure Limit (OEL): 1000 ppm v/v – 8 hr TWA value. Emergency and First Aid Procedures: Skin: Thaw affected areas with water, remove contaminated clothing carefully, wash affected areas of skin thoroughly with c

The voltage tolerance for each model is shown on the respective wiring diagram in this Manual. . The dryer must be fully isolated from the supply BEFORE maintenance work is started. . The dryer MUST NOT be used on other supplies without prior approval from the manufacturer. . The dryer should only be used in a SAFE (i.e. non- hazardous) area. . Observe any electrical safety labels fitted to various parts of the dryer. . Solenoid coils should not be removed from valve stem until they have been el

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”. These refrigerants require the use of ESTER oil within the system and not MINERAL oil as used with R22 systems, and therefore again these oils must NOT be mixed. Introduction The Denco C seri

(3) Leak test using pure refrigerant. (3) Leak test using Nitrogen and just a trace of refrigerant gas. (4) Recharge before mending leaks. (4) Find and mend leaks before recharging system. (5) Dispose refrigerant gas to waste. (5) Send used refrigerant gas back for reprocessing. Note: Disposal of refrigerants must be
