| 3 | Before attempting to carry out any work on our units, all accompanying documentation including warning labels on the unit must be referenced. Should it be necessary to remove any components ensure that these are secured into position once reinstalled. It is critical that after any maintenance work has been conducted that all components removed/replaced be refitted correctly by a competent engineer. | 15.0 minute |
| 4 | Before attempting to carry out any maintenance, investigative or repair work on our units, the unit MUST BE COMPLETELY ISOLATED from its electrical supply. Ensure a minimum of two minutes after electrical disconnection before removing access panels. This will allow any moving parts to come to a rest. Care should also be taken when accessing external units as the wind and elements may cause moving parts to ‘windmill’. When used in conjunction with an inverter for speed control, a minimum of 5 minutes should be given to allow for the capacitors to discharge before starting work after disconnection from the power source. | 15.0 minute |
| 5 | Ensure the unit has been allowed to completely cool before attempting any work to the unit. | 15.0 minute |
| 6 | Should a full service be required it may be necessary to disassemble the unit casework to gain access to some components. | 15.0 minute |
| 7 | When accessing the unit ensure the access panels are handled/opened in a controlled manner so as to avoid damage to the unit or injury to personnel. This is particularly important with bottom access units. | 15.0 minute |
| 8 | Should it be necessary to remove any slide-in components ensure that these are secured into position once reinstalled. It is critical that after any maintenance work has been conducted that all components removed/replaced be refitted correctly by a competent engineer. | 15.0 minute |
| 9 | Sufficient clearance should be provided to enable access to the unit casework, for confirmation of required access please refer to the appropriate outline drawing; note some access doors are hinged. | 15.0 minute |
