Before starting up the unit for the first time or after a long-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 electricity, water and replace the faulty parts.
Please use the parts provided or recommended by the company, do not
use the unqualified parts.
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
engineers or dealers.
