Safety Precaution - McQuay MDS080B R Installation Manual

For safety and proper installation of the units, please read this manual carefully before installation

1 Safety Precaution

Please take note of the safety item as followings before and after installation process:
1． ． ． ． 1 Preparation before Installation
● To check the electrical power supply condition, electrical power supply shall meet the requirement of local concerned rule and regulation;
● The tolerance of voltage shall be less than ±10% based on the nominal voltage, It is not allowed to share the same power cable for
welding, which will cause the vibration of power supply;
● To install the equipment , it is a must to have professional technician or Engineer to conduct the installation, otherwise, If installation is
completely improperly, will cause units leakage of water, electric power and cause fire accident etc;
● Please follow up the installation instruction of this manual to avoid any leakage of water, electric power and cause fire
● To set up an independent electrical power supply cable and meet the local concerned rule and regulation;
● Before installation of outdoor units, it shall build a solid base in the ground, also to take some measure to prevent the typhoon, earthquake
etc;
● The floor or base for installation of units shall be strong enough to support the weight of outdoor units; If intensity is not enough will cause
unnecessary damage of units and loss;
● To prepare the installation kits and protection kits , such as glove, uniform to avoid any kind of injury;
1． ． ． ． 2 Safety Notice on processing of installation
● Do not touch the fins of heat exchanger; Improper installation will cause body injury and fins damage to cause low heat exchange
efficiency;
● Do fix the outdoor unit tightly, to avoid any vibration; The cover panel of controller box shall be fixed tightly to avoid any dirt, water to enter
to cause some failure and damage;
● When installing the indoors units, please be sure the use the air filter and electrical heater provided by the supplier;
● When installing the units, in case the leakage of refrigerant, please open the window and door for good ventilation; to avoid any fire
because of the poisonous gas may occurred;
● If the indoor unit is installed in a confined limited space, it shall take prevent measure to avoid leakage of refrigerant;
● Cable of electrical power shall be far away from water, humidity, to avoid leakage of power and fire accidence;
● Do not change any protector setting, otherwise it will cause units failure , fire or explosion;
● Do not use the addition to check leakage of refrigerant;
● Please do not pull the cable of electrical power too tight, otherwise it will cause the breakage of cable;
● To ensure the cable can support sufficient ampere and power consumption;
● Units earthling is a must, to avoid any leakage of electrical power ; do not to connect earth line with telephone line;
● Indoor condensing water shall be drainage in proper way, to avoid dripping of condensing water, it shall have the insulation material to
wrap the outside layer of piping;
● Products shall be handled and carried very carefully, to find the profession people and right equipment for package and transportation of
units;
● After proper installation, it shall check the air tightness, to make sure no leakage of piping;
1． ． ． ． 3 Notice of test operation
● Before running the units, it shall to start the main switch for 12 hours, if not do in this way, it will cause the damage of components; The
power shall be in standby condition if units are required to operation frequently;
● Do not to contact the main power switch if the hand is wet to avoid leakage of electrical power;
● Do not to remove the front panel or protection guard when units is on operation; the high speed running part of the operation units will
cause unnecessary damage and injury;
● Do not the touch the refrigerant piping when units is running or just stop running, to avoid unnecessary hurt for hand because the piping
maybe too hot or too cold;
● Do not switch off the power when units stop running, wait for 5 minutes to shut off the electrical power;
