Indoor Air Handling Units

Greenheck’s Indoor Air Handling Series, models MSCF, LFC and VFC, provide air conditioning and/ or heating for buildings and specific spaces. The series was designed with low-profile construction to fit within tight spaces in applications such as schools, office buildings, apartments, medical facilities and many other commercial applications. Each model has a variety of sizes and a wide performance range with quiet, trouble-free operation.

Modular Indoor Air Handler

Model MSCF-FC Model MSCF-BI

Modular construction allows the design engineer to configure a unit to meet their exact requirements. The modular construction also makes the MSCF ideal for retrofit applications. (See pages 5 thru 9 for more information.)

Installation, Operation and Maintenance Manual

All units are shipped on a skid or packaged to minimize damage during shipment. The transporting carrier has the responsibility for delivering all items in their original condition as received from Greenheck. The individual receiving the equipment is responsible for inspecting the unit for obvious or hidden damage, recording any damage on the bill of lading before acceptance and filing a claim (if required) with the final carrier. Some accessory items are stored inside the unit during shipping. Care must be taken during installation to prevent damage to units.

Disconnect and secure all electrical power to the “OFF” position prior to inspection or servicing. Failure to comply with this safety precaution could result in serious injury or death.

Improper installation, adjustment, alteration, service or maintenance can cause property damage, injury or death. Read the installation, operating, and maintenance instructions thoroughly before installing or servicing this equipment.

Standard Features and Benefits

Greenheck’s Indoor Air Handling products have been designed with superior quality and come standard with premium features that make it ideal for any installation.

Low-Profile — Every model has been designed as a space saving alternative to other

products on the market. The height of each unit will be 4 to 8 inches less than any competitor

model.

Side Access Panels — Units are constructed with easily removable access panels. Panels are

formed and positioned on both sides of every module or unit to provide extra rigidity and help maintain cabinet pressure.

One-Inch Double-Wall — Double-wall construction on all units provides excellent indoor air

quality as well as improved radiated sound characteristics over traditional single wall and exposed insulation models.

Internal Isolation — Internal neoprene isolation and flexible blower to housing connection is

standard on every unit. This isolation improves longevity of the unit and reduces the potential of noise and vibration generated from fan vibration that could be transmitted to the attaching ductwork. Internal spring isolation is also available on all VFC sizes and on MSCF and LFC

sizes 20 thru 85.

Drain Pan — The double-wall constructed insulated stainless steel drain pan utilizes a double

pitch slope directing condensation to a main or auxiliary drain connection. The pan improves indoor air quality by preventing the growth of mold and bacteria. The drain pan removes easily for coil cleaning.
