1.First use
Before the first use, carefully read the manual to confirm the power range and environmental climate.
When the power is turned on, the temperature and snowflake icons will be displayed on the temperature control panel, indicating that the
power supply is normal and the machine is running.
In addition, if there is a lamp in the box, you can choose to turn it on or off according to your own situation.
2.The following foods must be packed in sealed containers or plastic wrap because they will produce
corrosive gases
1. Sushi rice, home cooked dishes, bread and other foods containing acetic acid and yeast;
2.Natto, bean curd, bean curd residue, bean stuffing and other bean processed products;
3.Boiled eggs, scrambled eggs and other egg processed products;
4.Fresh fish, ham, smoked and boiled products.

Be careful trictly distinguish the sensor lead, power line and output relay interface, and do not use them by mistake or overload;
This appliance is prohibited to be used in high temperature, high humidity, strong electromagnetic interference and strong corrosive environment;
The power supply voltage shall be consistent with the voltage marked on the machine to ensure stable voltage;
The buttons on the top can't be operated by non professionals at will.

六.Installation precautions (Split cabinet)
1、 Distribution environment
1).Customer site selection of power supply type: Single power 220V (3 or less) 、Three phase 380V (More than 3 horses).
2).Before power on, please check that the power supply voltage and frequency are consistent with the requirements, confirm the grounding, and configure D-type leakage protector;
2、 Installation position limit
1).15 ~ 20cm heat dissipation space must be reserved at the back of the whole cabinet and 60cm heat dissipation space must be reserved at the front
2).There shall be no air conditioner; fan and other equipment on or near the top of the air curtain cabinet, which will affect the air curtain;
3).Use high-power complete machine air curtain cabinet or multiple complete cabinets. If the indoor temperature rises, please add air conditioning equipment.
3、 Splicing
1).The splicing section shall be pasted with Shanghai cotton strips first, then marked with silica gel, and the spliced cabinet shall be fixed with bolts;
2).The connecting copper pipe shall be horizontal and vertical, and the use of elbows and tees shall be minimized. The air return pipe shall be sleeved with thermal insulation pipe;
3).After splicing, pour water at the bottom of the box to test to ensure that there is no water leakage and the water can flow away completely.
4
、
Drainage
1) .The drain is on the right side of the bottom of the cabinet. Please lay it <P 40pvc water pipe, led into outdoor or floor drain;
2).The drainage outlet shall be cleaned at least once a month and blocked by sundries.
5
、 Precautions for outdoor unit installation
1) .The outdoor unit should be placed in a cool, dry and well ventilated space to avoid direct sunlight, Wall mounted and floor mounted can be adopted;
3) the height difference between the unit and the cabinet is higher than 3m, please set an oil return bend (Oil return radius«5 times pipe diameter);
4).Short route and less bending are preferred for pipeline laying. The horizontal pipeline shall have a slight inclination angle of 1:125 to the outdoor unit side, air and oil return bends and anti countercurrent bends.
5).External unit accessories: Solenoid valve、 Ophthalmoscope, It needs to be installed in a reasonable position (Try to get close to the cabinet).
