A traceable service history
Organise the equipment inventory, service dates, completed work and outstanding observations. Link each report to a unit identified by model, serial number or internal code.
Documents suited to the activity
A maintenance report records completed work. It does not by itself confirm compliance of the entire premises or replace activity-specific requirements. The required format and retention period must be determined for the situation.
Preparing an enquiry
Record the model and room for each unit, observed symptoms and the last known maintenance. Describe access to indoor and outdoor units without dismantling components to obtain information.
For multiple units, keep a room-by-room list. Dates, work and associated records are agreed in the discussion according to the situation.
