8.3.1. Preparing for inspection and maintenance
Danger!
Risk of death caused by fire or explosion if there is a refrigerant leakage!
Only carry out the work if you are a competent person qualified to work with R32 refrigerant.
The product contains combustible refrigerant R32. In the event of a leak, escaping refrigerant may mix with air to form a
flammable atmosphere. There is a risk of fire and explosion.
Ensure that space is sufficiently aerated around the product.
Observe the basic safety rules before carrying out inspection and maintenance work or installing spare parts.
Disconnect the product from the power supply but ensure that the product is still earthed.
8.3.2. Cleaning the product
Do not clean the product with a high-pressure cleaner or a direct jet of water.
Clean the product using a sponge and hot water with a cleaning agent.
Do not use abrasive cleaners. Do not use solvents. Do not use any cleaning agents that contain chlorine or ammonia.
8.3.3. Checking the evaporator, fan, and condensate discharge
Check whether there is dirt between the fins or whether depositions have adhered to the fins.
Clean the fins using a soft brush, avoid fins from being bent.
Check whether dirt has accumulated on the condensate tray or in the condensate discharge pipe.
Check that the water can drain freely
Preparation
Before maintenance, please ensure that the unit has stopped
running and cut off the power supply.
Inspection and
cleaning of fin
heat exchanger
In order to ensure that heat exchangers remain in optimum
condition for heat exchange, their surfaces must be kept clean.
Inspection and
cleaning of plate
heat exchanger
Every 6 months or when the capacity of the unit drops by more
than 10%, check the water-side heat exchanger for scale and
clean the heat exchanger.
Check the
electrical wiring
Check if the contact point is loose, oxidized, or blocked by
sundries, etc., which causes poor contact of the electronic wiring.
