Johnson Controls Unitary Products

Increased horsepower motors and drive components are 
available for those applications where external static pres-
sure requirements exceed the capability of the standard 
motor.

Evaporator coil shall receive a 1-mil thickness of a cathodic 
epoxy type electro-deposition coating, applied in a multiple 
dip and bake process.

Evaporator coil (and optional Water Side Economizer coil) 
drain pan shall be fabricated 304 stainless steel material The 
3/4 in NPT drain connection fitting is also of 304 stainless 
steel.

Adjustable hot gas regulator and all necessary piping shall be 
installed on lead compressor circuit. Bypass capacity shall be 
minimum 50% of compressor capacity. The bypass valve 
opens at a preset suction pressure to prevent coil freeze-up 
at light evaporator load, or low airflow conditions. The use of 
factory installed Condenser Pressure Control option is 
strongly recommended when Hot Gas Bypass is installed.

Time delay relay will be provided for each compressor circuit. 
Compressor will be lock out for 5 minutes when thermostat 
contacts open, or there is a momentary power outage.

Commercial Water Cooled Air Conditioners can achieve sub-
stantial operating cost reductions by utilizing the cooling 
effect made available by low temperature water. The Water-
side Economizer Kit consists of a field installed water cooling 
coil, pre-assembled external piping sections, a three-way 
motorized valve, and all necessary controls for unit operation 
from a conventional 24-Volt thermostat.

Hydronic heating coils shall mount on return air side of cool-
ing coil.

Available on 5-15 ton CU models only. Recommended for 
applications where return air is not ducted and air is drawn 
directly from the conditioned space.

Plenums mount on top of the evaporator section, with fans 
arranged for vertical discharge. Double deflection grills shall 
allow air discharge in multiple directions.

Increased horsepower motors and drive components are 
available as a kit. Units are field upgradeable for applications 
where external staic pressure requirements exceed the capa-
bility of the standard motor.

Water regulating valves provide control of the quantity of con-
denser water supplied to the unit by sensing the condensing 
temperature. The field installed Condenser Control Option 
provides a regulating valve for each internal condenser water 
circuit. Standard Water Regulating Valve carries a 150 psig 
working pressure rating. The valve is installed inside of the 
unit cabinet.
