Roughing In, Continued
Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of the DOAS unit.
Doing so could result in fire, physical injury and/or death.
Do not work in a closed area where refrigerant or nitrogen
gases may be leaking.
Vapors may be present and can result in physical injury and/or
death.
Always use a pressure regulator to control incoming pressures
when pressure testing.
Excessive pressure may result in product damage, physical injury or
death.
Do not install this product outdoors or where it will be directly
exposed to coastal conditions.
Air from the ocean may cause the condenser and evaporator fins to

The information contained in this manual is intended for use by
a qualified, experienced service technician familiar with safety
procedures, and who is equipped with the proper tools and test
instruments.
Failure to carefully read and follow all instructions in this manual can
result in equipment malfunction, property damage, personal injury
and/or death.
This equipment uses high voltage electricity. Only a qualified,
experienced electrician should wire this system. Never assume
that the electrical power has been disconnected.
Verify with a meter.
Failure to follow all guidelines, properly respect electricity, use
industry best grounding practices, follow suggested wiring instruc-
tions, local, and NEC codes can lead to electrical shock, physical
injury, seizures, and/or death.
Use a properly sized circuit protective device. Using an
undersized protective device will lead to equipment malfunc-
tion. Installing an oversized protective device may cause burns,
fire, and death.
There is risk of fire, electric shock, explosion, physical injury and/or
death.
Properly secure power wires and communications cables at
connectors to eliminate wire strain.
Inadequate connections may generate heat, cause a fire and
physical injury and/or death.

SAFETY PRECAUTIONS
corrode, which may cause product malfunction.
Do not install this product in a location that is noise sensitive.
Provide additional acoustical treatment as needed.
The risk may be occupant discomfort.
When installing refrigerant piping, consider pipe expansion and
use flare connections.
Improper pipe installation may lead to pipe fatigue, failure, and a
rapid release of refrigerant, frostbite, suffocation, physical injury, and
/or death.
Verify the piping system has been properly evacuated (<500
ppm), and the system's refrigerant charge is correct before
commissioning and after any repair is made.
Improper system evacuation and / or an improper refrigerant charge
may cause product malfunction.
Verify all power, ground, and communications wires and cables
are properly terminated before applying power to the product.
Securely tighten all wire terminations.
Improper and/or loose wire and communications cable terminations
may cause product malfunction, fire, physical injury and/or death.
Turn power off at the unit disconnect before servicing.
Electrical shock can cause physical injury and/or death.
When servicing controls, ensure all wires are labeled properly
prior to disconnecting.
Wires labeled incorrectly could cause product malfunction, fire,
physical injury and/or death.
Properly replace all controls.
Failure to replace controls could result in fire and/or explosion.
Do not overload the VFD motor. The overload ampere setting
must not exceed 115% of the electric motors FLA rating as
shown on the motor nameplate.
There is risk of fire, electric shock, explosion, physical injury and/or
death.
Verify the DOAS unit is operational after servicing. Secure all
doors with a door latch or nut and bolt.
