SAFETY INSTRUCTIONS
INSTALLATION - CONTINUED
Don’t install the unit where it’s directly exposed to ocean winds.
Ocean winds may cause corrosion, particularly on the condenser and 
evaporator ns, which, in turn could cause product malfunction or inef-
cient performance.
When installing the unit in a low-lying area, or a location that 
is not level, use a raised concrete pad or concrete blocks to 
provide a solid, level foundation. 
This may prevent water damage and reduce abnormal vibration. 
Properly insulate all cold surfaces to prevent “sweating.” 
Cold surfaces such as uninsulated piping can generate condensate that 
may drip and cause a slippery oor condition and/or water damage to walls.
When installing the unit in a hospital, mechanical room, or 
similar electromagnetic eld (EMF) sensitive environment, 
provide sufcient protection against electrical noise.
Inverter equipment, power generators, high-frequency medical equip-
ment, or radio communication equipment may cause the air conditioner to 
operate improperly. The unit may also affect such equipment by creating 
electrical noise that disturbs medical treatment or image broadcasting.
Do not use the product for special purposes such as 
preserving foods, works of art, wine coolers, or other 
precision air conditioning applications. The equipment is 
designed to provide comfort cooling and heating.
There is risk of property damage.
Do not make refrigerant substitutions. Use R410A only.
If a different refrigerant is used, or air mixes with original refrigerant, the 
unit will malfunction and be damaged.
Keep the unit upright during installation to avoid vibration or 
water leakage. 
Do not install the unit in a noise sensitive area.
When connecting refrigerant tubing, remember to allow for 
pipe expansion.
Improper piping may cause refrigerant leaks and system malfunction.
Take appropriate actions at the end of HVAC equipment life 
to recover, recycle, reclaim or destroy R410A refrigerant 
according to applicable U.S. Environmental Protection 
Agency (EPA) rules.
Periodically check that the outdoor frame is not damaged. 
There is a risk of equipment damage.
Install the unit in a safe location where nobody can step on 
or fall onto it. Do not install the unit on a defective stand.
There is risk of unit and property damage.
Install the drain hose to ensure adequate drainage.
There is a risk of water leakage and property damage. 
Don’t store or use ammable gas / combustibles near the unit.
There is risk of product failure.
Always check for system refrigerant leaks after the unit has 
been installed or serviced.
Low refrigerant levels may cause product failure
The unit is shipped with refrigerant and the service valves 
closed. Do not open service valves on the unit until all 
non-condensibles have been removed from the piping system 
and authorization to do so has been obtained from the com-
missioning agent.
There is a risk of refrigerant contamination, refrigerant loss and equip-
ment damage.
Be very careful when transporting the product.
• Do not attempt to carry the product without assistance.
• Some products use polypropylene bands for packaging. Do not use 
polypropylene bands to lift the unit. 
• Suspend the unit from the base at specified positions.
• Support the unit a minimum of four points to avoid slippage from 
rigging apparatus.
If the air conditioner is installed in a small space, take 
measures to prevent the refrigerant concentration from 
exceeding safety limits in the event of a refrigerant leak.
Consult the latest edition of ASHRAE (American Society of Heating,  
Refrigerating, and Air Conditioning Engineers) Standard 15. If the  
refrigerant leaks and safety limits are exceeded, it could result in personal  
injuries or death from oxygen depletion.
Install the unit in a safe location where nobody can step on or 
fall onto it.
There is risk of physical injury or death.
