Quick Installation Guide

Read these Safety Precautions carefully to ensure correct installation.
This manual classifies precautions into WARNING and CAUTION.
WARNING
Only qualified personnel must carry out the installation work.
Ask your dealer or technical representative to install the unit.
Any deficiency caused by your own installation may result in an electric shock or fire.
All electrical work must be performed by a licensed technician, according to local regulations and in
accordance with the instructions in the installation manual.
Any lack of electric circuit or any deficiency caused by installation may result in an electric shock or fire.
Do not relocate or reinstall the CoolMasterNet by yourself.
Any deficiency caused by your own re-installation may result in an electric shock or fire.
Make sure that all wiring is secured, that specified wires are used and that no external forces act on
terminal connections or wires. Improper wiring connections or installation may produce heat and
result in fire.
Before touching electrical parts, turn off the unit.
To dispose of this product, consult your dealer.
Failure to follow WARNING is very likely to result in such grave consequences
as death or serious injury
Warning

CAUTION
Do not allow children to play with the CoolMasterNet and supervise them not to get access to the
appliance.
CoolMasterNet is not to be used by persons with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge.
Do not disassemble, modify or repair the CoolMasterNet.
Any deficiency caused by your modification or repair may result in an electric shock or fire.
Never let the CoolMasterNet to get wet.
Water can cause damage to the CoolMasterNet, and may cause an electric shock or fire.
Do not use flammable materials (e.g. hairspray or insecticide) near the
CoolMasterNet.
Do not clean the CoolMasterNet with organic solvents such as paint thinner. The use of organic
solvents may cause cracking, damaging the CoolMasterNet, causing electrical shock or fire.
Do not apply AC110V or AC220V to the CoolMasterNet. The maximum voltage that can be applied to
the unit directly is 24V DC.
If damaged CoolMasterNet can generate heat and cause a fire.
Failure to follow CAUTION may result in serious injury or property damage,
and in certain circumstances, may result in a grave consequence.
Caution

DO NOT INSTALL THE COOLMASTERNET IN THE FOLLOWING LOCATIONS:
a) Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen.
Plastic parts may deteriorate and fall off or result in water leakage.
b) Where corrosive gas, such as sulfurous acid gas, is produced.
Corroding copper pipes or soldered parts may result in refrigerant leakage.
c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of the CoolMasterNet and cause the unit to
malfunction.
d) Where flammable gas may leak, where there is carbon fiber or ignitable dust suspensions in the
air, or where volatile flammable such as thinner or gasoline are handled.
Operating the CoolMasterNet in such conditions can cause a fire.
e) High temperature area or directly flamed point.
Heating and/or fire can occur.
f) Moist area, where there is exposure to water.
If water enters the inside of the CoolMasterNet, it may cause electric shock and electrical components
may fail.
Failure to follow CAUTION may result in serious injury or property damage,
and in certain circumstances, may result in a grave consequence.

Changing the dip switches , while DC voltage is present on L1,
may damage the CoolMasterNet.
Non-VRV HVAC configuration
For Daikin/Mitsubishi Electric Non—VRV/VRF equipment, DC voltage supply by CoolMasterNet might be
required for proper operation.
Make sure CoolMasterNet is disconnected from power and HVAC line.
 Measure DC voltage on HVAC communication line L1
 If no DC voltage. Daikin 14-16V DC, Mitsubishi 28-30V DC, change the dip switches as shown below
 Turn ON the power for CoolMasterNet and connect it to HVAC line.
