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 magnetic filter and strainer.
(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 pressure is correct and and pressure vessel is in working
order, otherwise the performance and reliability of the unit will become
compromised.
Ensure the waterways are clean and avoid dirt and blockage.
Where heat pump components need to be replaced only use parts
provided or recommended by the company, do not use nonstandard
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
engineer or dealer.
