GENERAL REQUIREMENTS
IMPORTANT: NorthWind Air Conditioners have been engineered for the comfort of those using them. The ser-
vice life of the units can be extended by following the installation and preventive maintenance instructions.
NorthWind Portable Air-Cooled Air Conditioners are designed and built to cool a wide variety of applications by mov-
ing air through a 12 ½ x 7 inch evaporator discharge grille (Models MAC1211/1811), 18 ½ x 8 (Models
MAC3612/32), 22 x 11½ (Model MAC6012/32/34) and 23 x 11½ (Model MAC9032/34). These self-contained, port-
able units can direct air to specific areas or spots (spot cooling) through optional dual 5 inch diameter nozzles (Models
MAC1211/1811), 6 inch diameter dual nozzles (Models MAC3612/32), 8 inch diameter dual nozzles (Model
MAC6012/32/34) and 10 inch diameter dual nozzles Model MAC90/32/34). The 10 foot cord connected NorthWind
models range from 13,000 BTU/HR to 90,050 BTU/HR moveable floor mount configuration to meet most space re-
quirements. All models are equipped with 2 heavy duty, swivel w/lock front casters and 2 heavy duty fixed rear casters
for easy steering and parking control. MAC60 and MAC90 models have 4 swivel casters with rear swivel locks.
All models include a completely self-contained refrigeration system, air handling system (evaporator and condenser
blowers & motors), air filtration system (electrostatic filters), condensation removal system, and electrical supply and
control system in a professionally designed, neatly arranged heavy duty metal cabinet finished with exterior grade,
weather resistant, high gloss, polyester TGIC powder coating. Only power is required for operation. However, ducting
the condenser air out of the area is recommended. The 24 volt temperature controller provides the desired comfort and
unit control.
