Spot Check for air source water heater
Does the unit installation heat exchange space comply with requirements?
There should be discharge ditch or discharge outlet nearby the installation position
of the unit for convenient drainage.
Does the height difference between outdoor unit and water tank comply with unit
design requirements?
1) Installation foundation or support shall be firm enough to ensure stable operation
of unit.
2) The unit shall be level after installation.
Does the total length of connection pipe comply with requirements?
Does the diameter of cables connected with IDUs and ODUs comply with unit
design requirements?
Do the circuit breaker and leakage switch comply with unit design requirements?
If all power supply and control wires are connected properly?
If the wires are connected properly according to wiring diagram? If the unit is
grounded sufficiently? If all wiring terminals are connected reliably?
Confirm if the current installation location has the engineering diagrams for electrical
and control, etc.
Is the phase sequence of main power supply correct?
1) The installation location shall be strong enough to withstand the weight of water
tank.
2) The drainage port of water tank shall be near the discharge ditch or discharge
outlet.
3. If the pressure meter, pressure relief valve, auto discharge valve, etc. are installed
properly.
4. If the water level switch, temperature sensor and controller are installed properly.
If the inlet pipes and outlet pipes of hot water and cold water adopt insulation
pipeline.
If there is water overflows from the hot water faucet.
1) The distance between communication wire of wired controller and heavy current
wire shall be above 50mm.
2) The wired controller cannot be installed in high temperature and high humidity
places, such as kitchen and bathroom.
It is suggested to install the wired controller indoors. If it is installed outdoors, an
opaque rainproof protection box shall be applied in order to prevent the wired
controller from direct sunshine or rain.
3.3 Check before Debugging
3.3.1 Check for water system
1）Check if the water tank is installed reliably. If the installation location can withstand the
