Refrigeration Practitioner Registration

There is a certain amount of confusion regarding the issuing of Certificates of Conformity COC.

The Pressure Equipment Regulations (PER) require that a COC be signed off by the responsible person i.e. the  ‘Authorised Refrigeration Gas Practitioner’ registered with SAQCC Gas. Clause 17(3) clearly states: ‘An authorised person or an approved inspection authority shall issue a certificate of conformity after completion of a gas installation, modification, alteration or change of user or ownership on the form’.

ACOC form has been designed specifically for refrigeration and air conditioning.

Inspect air filters and inlet screens – At the very least, clean or replace filters at the start of each cooling and heating season. Clean the external air inlet screens at least once a year.

Inspect fan, housing and motor – Ensure that the fans are centered in their housing. Examine blades for severe corrosion, as well as chips, cracks, and dirt accumulation that can create noise and vibration.

Inspect belts for wear, proper tension and pulley alignment – Fan belts are a high-wear equipment that should be replaced once a year.

Check the heat exchanger – Gases could contaminate the building’s air supply if the heat exchanger rusts or fractures. Burners, igniters, and the combustion section should all be inspected (gas heat only). Ignition difficulties are indicated by popping, roaring noises, smoke, vibration, and flame rollout.

Check for leaks and test the gas pressure.

Clean drainage – Clogged drain channels make it difficult for water and other liquids to exit the unit, which can lead to damage to the unit and its surroundings over time.

Check the refrigerant charge.

Check for voltage imbalances.
