5. Installation and Debugging5.1 Operating conditions:The heat pump operates normally under the following conditions:Ambient Temperature: -8℃-43℃Relative Humidity: ≤95%Power Supply: 220V/-/50Hz Any conductive material, explosive gas, or corrosive gas that woulddamage the metal or isolation material of heat pump should not be in thevicinity. The unit is recommended to be installed outdoors or in the basement.5.2 Transportation and Installation: During transportation the unit must be right side up and should not beinclined more than 30° degrees from the vertical.The unit must be positioned with clearance in the front and on both sides: 1mfrom the front and 2m from both sides. The unit should be firmly installed withinan inclination ≤2/1000. The 220V/50Hz power supply should not be too far away from the unit toavoid high pressure drop when compressor starts. It is suggested to use2.5~16mm 2 four-core cable without joints and power switch with residualcircuit breaker. Wiring according to the electric drawing. Be sure the unit iswell grounded (a 5meter ground line is supplied with the unit).Inlet and outlet pipe connections should be checked to avoid leaks and anyexcessive pressure. A valve, filter and pressure gauge should be installed at theinlet side to control the input water pressure and flow and clear the water before itgoes into the circulation system. Refer to the installation drawing (page 3) forinstallation details. Pressure of the circulation pipes inside the heat pump should bewithin the limit of 0.6MPa.The heat pump can be connected to a solar system if needed:Clear the water inside the system if the unit is to be stopped for a long time toavoid frozen and damage of heat exchanger and water pump in cold winter.Instruction of drainage:a) Remove the four screws at the bottom of the back plate and the drainagePage 7 of 19

pan.b) Turn the knob of the outfall under the condenser to a 90°round (forward orreverse) and the water inside the system will flow out.c) Turn the knob to the original position after the water is clean.d) Replace the back plate and refit it to the drainage pan.★Note on re-operation of the unit: Filling water tank before electrified, thenpower on the unit; make sure clearance of water pump (see Debugging process a).5.3 Debugging:Each unit has been tested before leaving the factory. Users do not need tomake any changes. Ensure correct connect of the unit to the external watercirculation system. Then connect the power supply and check if there is anydamage or leak. After that the unit is ready to be switched on.The debugging processes are:a) Fill the water tank to a demand height, open all the valves and empty thewhole waterway system, be sure there is no air in the pipes, or it will causemalfunction of water pump and the unit.b) Be sure all wire connections are correct according to the electric drawing.c) Set the water temperature referring to the Controller Instruction section.d) Press the “on/off” button for 3 seconds, fan motor and water pump willstart in 3 minutes; compressor starts 1 minute later and begins to heat the water. Ifan electric assistant is installed, the electronic control system may activate theassistant heater when the ambient temperature is sensed to be 2degree C. No userintervention is required.e) The system will automatically check the release temperature, coiltemperature, intake temperature, water temperature, as well as water outlettemperature while the unit is operating. If an error occurs, the error code will bedisplayed on the control panel.f) Compressor stops running when the water reaches its set temperature; fanmotor and water pump stop 1 minute later.g) Defrosting will be done automatically when the ambient temperature is toolow to prevent ice on surface of the evaporator.

When the heat pumps are electrified, the controller automaticallysenses the water temperature and if the water temperature sensor is faulty, it will give a sign ofcommunication error and shows E10 on the display. But when the heat pump is running, it willshow E08 as the error of the water temperature sensor error.Instructions for multiple-installation (several heat pumps installed in parallel):1. P9 on the controller shows the quantity of heat pumps in a multiple-installation. Setting rangegoes from 1~16, default to be 1.2. Controller for the major heat pump and subsidiary one works likewise. The water temperaturesensor connects to the major heat pump only. Those without this sensor are determined to besubsidiary unit.3. The subsidiary heat pumps will be sorted in series and keep the same controlling functions asthe major unit.Page 15 of 19

4. The data for each subsidiary heat pump can be checked on the controller by pressing “ ”and then the “clk”. Pressto check each data with a form of “ndxx” (n: number of thesubsidiary unit; xx: number of the data; ndl=intake temperature, nd2=coil temperature,nd3=opening of expansion valve, nd4=release temperature, nd5=running time of the subsidiaryunit, nd6=outdoor temperature, nd7=water outlet temperature, nd12=solar temperature;nd8~nd11 only available for heat pump model RS-280Y5A/T).Press “clk” to retreat the checking mode.5. Communication lose: error code shows as dnXX (xx: number of the subsidiary unit), pleasecheck the connection and fix it.6. Single error for subsidiary unit, showing as: dexx (xx=number for the error, d=number of theerror subsidiary unit).7. The single and double system must be set through controller. The subsidiary unit automaticallychecks out if there is a second system, if not, it will explain it a single system.If connected to the net, please connect end of “a” and “b” to make it functioned.When the heat pump is decided to be a subsidiary unit, it will depend on the position of thetoggle switch to make the sequence of the subsidiary.

8. Important Notes8.1 After the installation, please add on a flashing shed to prevent rain or snowfrom dripping directly onto the machine. The ambient temperature is relatively lowwith higher humidity in winter, thus the vent side would be easily covered by iceafter some times of accumulation. Therefore, the performance as well as life spanof the unit will be affected without protection of a flashing shed; the worstsituation may lead to bad function of heat pump.Flashing shedHeat pumpRequirement of the flashing shed:It must cover the whole unit, with the size: front of shed 100mm over front of heatpump; back of shed 400mm over back(with net) of heat pump; right side of shed100mm over right side of heat pump; left side of shed 400mm over left side(withnet)of heat pump. The details are specified in the pictures above.Page 17 of 19

8.2 If the heat pump is connected to a pressurized water tank, make sure the tankmeets with the requirement in P1 and P2. Water pump should be Wilo pumpPUN-200E. All the problems happened to heat pump caused by unfixed water tankor water pump should be responsible by the installer.″hot outwater″water temp sensor″outlet fromheat pump″″clod inlet fromtap waterinlet fromheat pumpL pressurized tankPage 18 of 19
