9.Trial run
9
.1.Check the hot water side, air-conditioning side and solar side of the water system piping and all accessories
are installed correctly, heat pumps, water tanks, terminal equipment piping connections are correct. The fill
water supply of hot water side, air-conditioning side and solar side are normal, the replenishment port
whether installed pressure relief valve, one-way valve, filter and other accessories.
9.2.Open the unit hot water side, air-conditioning and solar side hydrating valve, circular inlet and outlet water
valve, main pipe backwater valve, floor branch pipe valve, terminal equipment inlet and outlet valve, fill the
hot water side water tank, air-conditioning side water tank and solar collector system with water. Check the
valves should be open if all open, the valves should be closed if all closed, pipe insulation if complete.
9.3.Open the exhaust valve, hot water valve, drain the pipe air, confirm pipe clean, close the exhaust valve, hot
water valve.
9.4.Check the power supply if required with the unit power supply on the nameplate, power supply voltage if
normal.
9.5.Check all power supply and control wires are all connected in place, whether connect correctly according to
the cable wiring diagram, all the terminals are tightened and check the reliability of ground connection.
9.6.Test Hot water side, air-conditioning side, solar side water system to test, first of all, heat pump units
connected to power supply, operating the remote controller (refer to the remote controller operation), start
the hot water side, air-conditioning side, solar side circulating pump, opened the exhaust valve again to drain
the pipe air, observe and listen water pump operation, the circulating water flow whether normal. Until the
hot water side, air-conditioning side, and solar side circulating water system work completely normal, close
the hot water side, air conditioning and solar side circulating pump.
9.7.When a full inspection of the entire system to install correctly and meet the requirements, may carry out the
whole test run.
9.8.Operate the unit controller, select the heat pump working mode and setting temperature, back to controller
main interface, press
to start the heat pump.
9.9.First water pump operate 30s, the compressor starts. To determine unit operation if have different sound
through hearing, if is, shunt down power immediately and check, only continue running if there is no different
sound, at the same time pay attention to system high and low pressure if normal.
9.10.Check again whether the unit input power and current normal, if not, then shut down to check.
9.11 View the unit control operation status display, check and record the unit's output and input status, the value
of each point temperature indicated if normal.
9.12.Operate the unit controller, change the heat pump working mode, check and record the unit's output and
input status, the value of each point temperature indicated if normal. Unit put into normal run only after
checking all the working modes are normal.
Note:
1 unit the first time power on without three minutes delay protection, other times there is three minutes delay
protection.
2 must clean the pipe air when first the unit boot.
