Regular Inspection Of The Project - Haier CA0065EANR Service Manual

6.6 Regular inspection of the project

Before delivery, the unit has been rigorously tested and inspected to ensure that the product has good
performance after leaving the factory. In order to ensure long-term good operation of the unit, the user should
carry out regular maintenance and maintenance.
1. Condenser inspection and cleaning
In order to ensure the effective work of the condenser and the maximum heat exchange, the outside must be
cleaned without any contaminants such as fallen leaves, lint, insects and the like that easily block the condenser
fins.
2. Inspection and cleaning of heat exchangers
To determine if the water side heat exchanger is clean, check the heat and water temperature of the heat
exchanger and compare it to the evaporation temperature. For example, if the outlet temperature and the
evaporation temperature differ by more than 5~7 °C at the rated water flow rate, the operating efficiency of the
heat exchanger has been reduced and cleaning is required.Since some chemical treatment is required during the
cleaning process, cleaning must be done by a professional.
3. Replenishment of refrigerants and lubricants
Each unit is shipped with sufficient refrigerant R410A and lubricant. When the system is working properly, there
is no need to replenish refrigerant or lubricating oil, and it is not allowed to charge or replace refrigerant and
lubricant. If it is necessary to replenish due to leakage, please refer to the charging amount specified on the
nameplate on the unit.
