General Information

• This manual should always be accessible and close to this air condition equipment.

• There are two types of indications, " WARNING" and " CAUTION". The indication preventing from death

or heavy injury is listed as " WARNING". Even the indication listed as " CAUTION" may also cause serious

accident. Both of them are related to safety, and should be strictly followed.

•After installation and start-up commissioning, please handover the manual to the user. The manual should be well

kept in safe place and close to the unit.

• The installation or the maintenance should be performed by an authorized agency. The wrong operation of this air

condition equipment may cause water leakage, electric shock or re.

• Please install the unit on the top of a solid foundation or structure which is strong enough to support the unit.

• The installation of this air condition equipment should follow local construction codes.

• Use the right cable size, secure the terminal rmly, organize the cables well and make sure no tension is added

on cables. Cable insulation should not be damaged. The incorrect installation may lead to overheat or re.

• Must install leakage protection switch, or it will cause electric shock.

• Please install the ow switch which in the outdoor accessory in the middle of the outlet pipe.

• In winter, if you do not use for short periods of time, please ensure the machine 24 hours power on, if you do not

use for a long time, please sent out the water in the system, prevent frost crack system.

• When installing or moving the unit, the refrigerant system should be vacuumed and recharged with R410A

refrigerant. If any other gas enters the system, it may lead to abnormal high pressure which may cause damage or

injury.

• Please use the proper manifolds or branches during the system installation. The wrong parts may cause

refrigerant leakage.

• Keep the drain pipe away from toxic gas vents to prevent possible pollution of indoor environment.

• During or after the installation, please check whether there is refrigerant leakage. If any leakage, please take any

measures for ventilation. The refrigerant may be toxic at some concentration levels. The unit connect with closed

water system

• The unit is not explosion-proof. Please keep it away from ammable gases.

• The water pipe should be installed per this manual to ensure proper drainage. The pipe should be well insulated

to avoid condensation. Wrong installation may lead to water leakage.

Both liquid pipe and the gas pipe should be also well insulated. Not enough insulation may lead to system

performance deterioration or humidity formation.

• This air condition equipment is not intended to be operated by persons with lack of experience and training, unless

they have supervision or instruction concerning use of this air condition equipment.

• Please keep children away from this air condition equipment.

• The grade of waterproof and dustproof is IPX0, Please pay attention to waterproof.

WARNING

1. General Information

1.1 Safety

• Grounding wire should be connected with the grounding bar. The grounding wire can not be connected to the gas

pipe, water pipe, lightening rod or the telephone grounding wire. Improper grounding may cause electric shock.

• Units installed on roof should have appropriate access and handrail.

• Use the wrench to fasten the nut and are at proper torque. Excessive torque may cause ared section to broke

leading to refrigerant leakage.

• After refrigerant pipe installation, please take nitrogen leakage test to avoid refrigerant leakage.

• R410A is the only permitted refrigerant.

• To avoid mischarging wrong refrigerant, the check valve diameter is changed for R410A. To strengthen the pipe,

the ared pipe dimension is also changed. Please use R410A specied tools as shown below.

• When charging refrigerant, the refrigerant must be in liquid state from the tank.

• To prevent EMC interference on other appliances, please keep indoor unit, outdoor unit, power cable and

connecting wire at least 1m away from those appliances.

• Fluorescent lamp (reverse phase or rapid start type) may interfere with the remote controller's signal. Please

install indoor unit away from uorescent lamp. The farther the better.

• The temperature and ow of the outdoor unit inlet water need to conform to the requirements of the specication,

the water temperature is too low or the water is too small will cause the unit malfunction.

• The water pipe network including water lter and tube heat exchanger need to regularly clean, otherwise it will

decrease the capacity.

• The quality of the circulating water must conform to the specications. otherwise it will decrease the system life.

R410A specied tools Remarks

1 Gauge manifold Range: HP>4.5MPa,LP>2MPa

2 Charge hose Pressure: HP 5.3MPa, LP 3.5MPa

3 Electronic weight for charging R410A No other means permitted

4Torque wrench

5 Flare tool

6 Copper pipe gauge for adjusting projecting margin

7Vacuum pump tting Vacuum pump must be equipped with check valve

8 Leakage detector Only Helium detector permitted

General Information

1.2.2 Double EEVs control

The double EEVs control the 2 stages heat exchanger separately, which can adjust the condenser volume and

optimize system performance.

1.2.3 Energy Saving: Heat recovery between different refrigerant system

Heat recovery is achieved within the water loop among different refrigerant systems, higher whole system efciency

due to cooling and heating simultaneously in different refrigerant systems.

1.2 Feature

1.2.1 User friendly outdoor structure

1.2.5 Water pump controlled together with the outdoor

The reserved water pump linkage control realizes the pump linkage control, reduces the energy consumption and

eliminates hidden risks.

1.2.6 High reliability

Wide operation range

1.2.7 High convenience (use/installation/service)

• Various mode and priority selection.

• The outdoor units are smaller and can be staked, reducing the installation space and increasing the customers

usable space.
