7. Maintenance
7.1. Precautions for Daily Use
Before starting up the unit for the first time or after along-time shutdown, the
following preparations must be made:
(1) Thoroughly inspect and clean up the unit.
(2) Clean the waterway system.
(3) Check water pump, regulating valve and other waterway
equipment.
(4) Tighten all wire connections.
Do not change the system parameters before consulting the engineer.
Ensure the water refill and exhaust device in the waterway is well, otherwise
the performance and reliability of the unit will become worse.
Ensure the waterways are clean and avoid dirt and blockage.
Timely check the electrical, water and replace the faulty parts.
Please use the parts provided or recommended by the company, do not use the
parts unqualified.
Refrigerant supplement:
Each unit has been equipped with sufficient refrigerant when leaving the factory.
Do not charge or change the refrigerant.
If you need to replenish the refrigerant due to leakage, please contact the
engineer or dealer.

7.2. Periodic Maintenance (every 6months)
7.3. Inspection and Maintenance
7.3.1. Preparing for inspection and maintenance
Danger!
Risk of death caused by fire or explosion if there is arefrigerant leakage!
Only carry out the work if you are competent and have knowledge about the special
features and risks of R32 refrigerant.
The product contains combustible refrigerant R32. In the event of aleak, escaping
refrigerant may mix with air to form aflammable atmosphere. There is arisk 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.
7.3.2. Cleaning the product
Do not clean the product with ahigh-pressure cleaner or adirect jet of water.
Clean the product using asponge and hot water with acleaning agent.
Do not use abrasive cleaners. Do not use solvents. Do not use any cleaning agents
that contain chlorine or ammonia.
7.3.3. 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 asoft 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 stop
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 6months 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.
