Note:
.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, ony-way valve,
filter and other accessories.
11.2.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.
11.3.Open the exhaust valve, hot water valve, drain the pipe air, confirm pipe clean, close the
exhaust valve, hot water valve.
11.4.Check the power supply if required with the unit power supply on the nameplate, power supply
voltage if normal.
11.5.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.
11.6.Test Hot water side, air-conditioning side, solar side water
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.
11.7.When a full inspection of the entire system to install correctly and meet the requirements, may
carry out the whole test run.
11.8.Operate the unit controller, select the heat pump working mode and setting
temperature, back to controller main interface, press
to start the heat pump.
11.9.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.
11.10.Check again whether the unit input power and current normal, if not, then shut down to check.
11.11.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.
11.12.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.
