Keep the unit upright during installation.
To avoid vibration or water leakage.
When installing the water source unit in a low-lying area, or
a location that is not level, use a raised concrete pad or con-
crete 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 floor condition and / or water damage to
walls.
When installing the unit in a hospital, data center, or similar
electromagentic field (EMF) sensitive environment, provide
sufficient 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 creat-
ing electrical noise that disturbs medical treatment or image broadcasting.
Do not use the product for special purposes such as pre-
serving 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.
When connecting refrigerant tubing, remember to allow for
pipe expansion.
Improper piping may cause refrigerant leaks and system malfunction.
Do not install the water source unit in a noise sensitive area.
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.
INSTALLATION, CONTINUED
Note:
SAFETY PRECAUTIONS
Replace all control box and panel covers.
If cover panels are not installed securely, dust, water and animals may
enter the water source unit, causing fire, electric shock, and physical in
-
jury or death.
Install the unit in a safe location where nobody can step on
or fall onto it.
There is risk of unit damage, physical injury or death.
Always check for system refrigerant leaks after the unit has
been installed or serviced.
Low refrigerant levels may cause product failure, and exposure to high
concentration levels of refrigerant gas may lead to illness or death.
