1. Safety precautionary measure
!
WARNING
1. This air conditioner is a comforting unit which cannot be used in any
special place for storing machines, precise instruments, food, plants,
poultries or artworks, etc.
2.The installation work must be done by the distributor or a professional
worker.
3.The installation worker must be equipped with all related knowledge as
a wrong operation may cause fire risk, electric shock, injury or water
leakage, etc.
4.If the unit is to be installed in a small room, suitable measures shall be
taken to make sure any refrigerant leakage concentration if happened in
the room will not exceed the critical level.
5.For detailed measures, place consult with the distributor.
6.Connection of power supply must be complying with rules specified by
the local electrical authority.
7.If the air conditioner is to be moved or reinstalled, please let the
distributor or a professional worker operate.
Incorrect installation will cause fire risk, electric shock, injury or water
leakage, etc.
8. The user is not permitted to rebuild or repair the unit of own
accord.Incorrect repairing will cause fire risk, electric shock, injury or
water leakage, etc, so repairing must be performed by the distributor or a
professional worker.
9. The A-weighted sound pressure level is below 70dB.
10.This appliance is intended to be used by expert or trained users in
shops, in light industry and on farms, or for commercial use by lay
persons.
11.The appliance shall be disconnected from its power source during
service and when replacing parts and, if that the removal of the plug is
foreseen, it shall be clearly indicated that the removal of the plug has to
be such that an operator can check from any of the points to which he has
access that the plug remains removed.
12.The appliance shall be maintained by the professional every three
years.
!
NOTICE
1.Make sure the water drainage ditch is useable.
2.Make sure a current leakage protection switch is equipped.
3. The current leakage protection switch must be equipped or there may
be an electric shock.
4.It mustn't be installed in any position with potential leakage of
inflammable gas.
5.If any inflammable gas leaks, there may be a fire risk around the
indoor unit.
6.Make sure the foundation installation or suspending installation is firm
and reliable.
7.If the foundation or suspension is not firm and reliable enough, there
may be a fall accident.
8. Make sure all electric cables are correctly connected.
9.If any electric cable is incorrectly connected, any electrical part may be
damaged.
10.If the refrigerant leaks during installation, the room must be ventilated
at once.
11. The leaked refrigerant may generate some toxic gas if it contacts any
flame.
12.After installation, make sure there is no refrigerant leakage.
13. If the refrigerant gas enters and contacts some flame source such as
a heater, a stove or an electric cooker, it may generate some toxic gas.
14.A lightning protection device must be equipped as per the applicable
national regulation, or the machine may be damaged by a lightning strike.
!
NOTICE
1.The products are not to be connected to public low voltage a.c
distribution systems.
2.The appliance shall be installed in accordance with national wiring
regulations.
3.Stationary appliances not fitted with means for disconnection from the
supply mains having a contact separation in all poles that provide full
......12
disconnection under overvoltage category III, the instructions state that
17
means for disconnection must be incorporated in the fixed wiring in
accordance with the wiring rules.
4. If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in order to
avoid a hazard.
5.This appliance can be used by children aged from 8 years and above
and persons with reduced physical, sensory or mental capabilities or lack
of experience and knowledge if they have been given supervision or
instruction concerning use of the appliance in a safe way and understand
the hazards involved.
6.Children shall not play with the appliance.
7. Cleaning and user maintenance shall not be made by children without
supervision.
8. GWP:R410A:2087.5.
9.Disconnect the power supply before cleaning and maintenance.
2. Key points in installation inspection
2-1 Receival and unpacking inspection
1) When the machine is received, check if there is any damage in
transportation. If any surface or internal damage is found, please inform
the transportation agency in a written form.
2) After the machine is received, check if the device type, specification
and quantity are complying with the contract.
3) When unpacking the product, please well keep the instruction manual
and check all accessories.
2-2 Refrigerant tube
1) The refrigerant tube installation must be performed by the special
refrigerant dispenser (separately ordered) for the manufacturer central air
conditioner.
2) The refrigerant tube must be of the specified tube diameter and tube
wall thickness.
3) Copper tube welding must be performed with nitrogen filled
protection, and the tube must be filled with nitrogen gas of 0.02MPa which
cannot be cut off until welding is completed and the copper tube is
thoroughly cooled down.
4) The refrigerant tube must be treated with thermal insulation.
5) After the refrigerant tube is installed and before gas tightness test and
vacuumization, the indoor unit cannot be electrified.
2-3 Gas tightness test
After the refrigerant tube is installed, nitrogen gas of 40kgf/cm (4.0MPa)
must be filled from the gas side and liquid side at the same time for 24-
hour gas tightness test.
2-4 Vacuumizations
After the air tightness test, vacuumization (vacuum degree -0.1MPa)
must be performed from both the gas side and the liquid side at the same
time.
2-5 Refrigerant refilling
1) The volume of refrigerant to be refilled is calculated on the diameter
and length (actual length) of the tubes at the outdoor unit and indoor unit
liquid side.
2) The volume of refrigerant to be refilled, liquid tube diameter, tube
length and height difference between the outdoor unit and indoor unit
shall be recorded on the confirmation table (on the cover of the electrical
box) for future reference.
2-6 Electrical wiring
1) The selection of power supply capacity and wire diameter shall be
complying with the design manual. The diameter of power supply cable
for an air conditioner is usually larger than the diameter of motor cable.
2) To prevent any disoperation of the air conditioner, the power supply
cable (380-415V 3N～) can not be twisted with any connecting cable of
outdoor unit and indoor unit (low voltage cable).
3) The indoor unit can be electrified after gas tightness test and
vacuumization.
4) The location of outdoor unit must be set, as shown in Chapter 5.4, and
the SW6 dialing code must be set within 0~3, in which, 0# is the
dominating unit and others are dominated units.
2-7 Trial running
1) The two pieces of pearl cotton protecting the condenser at the back of
the unit shall be removed before trial running. They must be taken out
carefully so as not to damage the fins or the performance of thermal
exchange will be influenced.
2) Trial running cannot be started unless the outdoor unit is electrified
and preheated for more than 12h, or the system may be damaged.
