UNIT NOMENCLATURE

Chassis/Model Type

Multi V Ducted Indoor Units

Due to our policy of continuous product innovation, some specifications may change without notification.

R410A REFRIGERANT

R410A refrigerant has a higher operating pressure in comparison to R22 refrigerant and, therefore, all piping system materials

installed must have a higher resisting pressure than the materials traditionally used in R22 systems.

R410A refrigerant is an azeotrope of R32 and R125, mixed at 50:50, so the ozone depletion potential (ODP) is 0.

WARNING

• Do not place the refrigerant cylinder in direct sunlight. Refrigerant cylinder may explode causing severe injury or death.

Note:

• Because R410A is a combination of R32 and R125, the required additional refrigerant must be charged in its liquid state. If the

refrigerant is charged in its gaseous state, its composition changes and the system will not work properly.

• Do not heat piping more than necessary during installation. Piping may become soft and fail when pressurized.

• Do not use any piping that has not been approved for use in high-pressure refrigerant systems. Piping wall thickness must comply

with the applicable local, state, and federal codes for the 551 psi design pressure of R410A. Inadequate piping may fail when

pressurized.

Installation Manual

Due to our policy of continuous product innovation, some specifications may change without notification.

Power Input is rated at high speed.

Take appropriate actions at the end of HVAC equipment life to recover, recycle, reclaim or

destroy R410A refrigerant according to applicable regulations (40 CFR Part 82, Subpart F)

under section 608 of CAA.

All communication cable to be minimum 18 AWG, 2-conductor, stranded, shielded and

must comply with applicable local and national codes. Ensure the communication cable

is properly grounded at the master outdoor unit only. Do not ground the ODU−IDU com-

munications cable at any other point.

EEV: Electronic Expansion Valve

Power wiring is field supplied and must comply with the applicable local and national

codes. Power Supply (V/Hz/Ø): 208-230/60/1

This unit comes with a dry nitrogen charge.

This data is rated 0 ft above sea level, with 25 ft of refrigerant line per indoor unit and a 0 ft

level difference between outdoor and indoor units. All capacities are net with a combina-

tion ratio between 95-105%.
