1. Safety Precautions
Read the following SAFETY PRECAUTIONS carefully before installation.
Incorrect installation may cause injury, death, or damage.
Before installing or using your solar heat pump mini-split, please print and read
this manual carefully and keep it for future reference.
1.1 Notice to Owner/Installer:
This unit is designed for easy installation by an experienced person. It is legal for a
homeowner to install it, however we highly recommend using a licensed HVAC technician
for installation.
Legal Information About Self-Installing R410A Heat Pump Mini-Split Systems
Can a homeowner install this system?
Yes, a homeowner with a vacuum pump, proper training, and equipment can install this
unit. Unless you are experienced with installing a heat pump mini-split we recommend
you hire a professional installer. The person who installs the system must do all work in
compliance with local building and electrical codes.
Are there any restrictions on the purchase of R410A refrigerants?
R410a is not an ozone-depleting substance. At this time the purchase of R410a
refrigerant is not restricted in the US. There is no technician certification requirement for
those that purchase HFC refrigerants, such as R-410a or R-134a. If you are not licensed,
some local HVAC supply companies may refuse to sell you R410a based on a
misunderstanding of the law, or because they wish to discourage homeowners from
working on their own systems.
Are there any restrictions on the use of R410A refrigerants?
Yes, it is illegal to knowingly vent or release these refrigerants. The venting prohibition
applies to R410a, and all other HFC refrigerants, just as it does for ozone-depleting
refrigerants like R-22.
Is EPA technician certification required to service R410A systems?
No, at this time EPA technician certification is not required in order to service R-410a
systems.

and evaporator.
This equipment must be installed with DC ground-fault protection (NEC 2005,
Article 690.5) Refer to grounding section in this manual.
Install drainage line descried in the installation instructions. If drainage is not
proper, water may accumulate and cause damage.
Always check for gas (refrigerant) leakage after installation or repair of product.
Low refrigerant levels may cause failure of product.
If strange sounds or smoke comes from product, turn the breaker off or
disconnect the power supply cable.
Do not use the product in a tightly closed space for a long time. Oxygen
deficiency could occur.
Do not block the inlet or outlet of air flow.
Do not step on or put anything on the product. (outdoor units)
Do not let the air conditioner run for a long time when humidity is very high and a
door or a window is left open.
