Air Cooled with Floor Mounted Indoor Condenser - The refrigeration system shall be split type with an indoor evaporator sec-

tion and ﬂ oor mounted indoor condenser. The indoor evaporator section shall include the cooling coil, compressor, humidiﬁ er,

reheat, ﬁ lters and controls. The cooling coil shall be in an “A” frame arrangement to allow maximum coil surface in a small

cabinet. The large faced area coil shall be constructed with

/2” O.D. copper tube with 12 ﬁ ns per inch of corrugated aluminum

for maximum heat transfer. Maximum face velocity shall be less that 500 feet per minute. The expansion valve shall be of the

adjustable thermostatic type with external equalization. The compressor shall be hermetic scroll type, with complete overload

protection on all three power lines, internal thermostat for winding protection, crankcase heater, sight-glass and low pressure

override timer for positive starting at low temperatures. The ﬁ lter drier shall be of the ﬂ are ﬁ tting type for non-torch servicing.

The circuit shall contain high and low pressure safety switches. The high and low safety pressure switches shall be installed with

shraeder type ﬁ ttings with valve core.

Each system shall include a ﬂ oor mounted, indoor air cooled condenser section. The condenser frame shall be constructed of 14

gauge welded tubular steel and be coated with a heavy corrosion inhibiting ﬁ nish for long life. The unit shall have complete front

and side access by means of high quality furniture grade steel doors with heavy duty hinges. The doors shall be lined with one

inch (1”) thick, 1-1/2 pound density ﬁ berglass coated with neoprene. Each door shall be provided with sure close latches which

shall be quickly removable for easy access and a polyurethane gasket to prevent air leakage. The doors shall be painted to match

or contrast with other room equipment. The blower section shall be belt driven centrifugal type, double width, double inlet and

shall be statically and dynamically balanced at the factory as a complete assembly to a maximum vibration level of two mills in

any plane. The blower wheel shall be supported on a heavy steel shaft having self-aligning ball bearings with a minimum life

span of 100,000 hours. The blower wheel shall be driven by a motor mounted on an adjustable slide base. The drive motor shall

be 1750 rpm. The drive package shall be belt driven with two (2) belts and a variable pitch sheave, sized for 200% of the fan

motor horsepower.

The condenser coil shall be constructed of copper tubes and corrugated aluminum ﬁ ns. A receiver shall be factory mounted with

head pressure control and liquid line solenoid valve.

Air Cooled with Remote Outdoor Condensing Unit - The refrigeration system shall be split type with an indoor evaporator sec-

tion and remote outdoor condensing unit. The indoor evaporator section shall include the cooling coil, humidiﬁ er, reheat, ﬁ lters

and controls. The cooling coil shall be in an “A” frame arrangement to allow maximum coil surface in a small cabinet. The large

faced area coil shall be constructed with

/2” O.D. copper tube with 12 ﬁ ns per inch of corrugated aluminum for maximum heat

transfer. Maximum face velocity shall be less than 500 feet per minute. The expansion valve shall be of the adjustable thermo-

static type with external equalization.

The outdoor condensing unit shall be constructed of aluminum and contain a hermetic scroll compressor with complete overload

protection on all three power lines, internal thermostats for winding protection, crankcase heater, sight-glass and low pressure

override timer for positive starting at low temperatures. The ﬁ lter drier shall be of the ﬂ are ﬁ tting type for non-torch servicing.

The circuit shall contain high and low pressure safety switches. The high and low pressure safety switches shall be installed with

shraeder type ﬁ ttings with valve core.

The condensing unit shall include a low proﬁ le, slow speed, direct drive propeller fan air cooled condenser section. The air dis-

charge shall be vertical to minimize the effects of wind blowing through the coil at low ambient temperatures. The condenser

coil shall be constructed with copper tube and aluminum ﬁ n. The condensing unit shall have fan speed control with transducers

to modulate the speed of the ﬁ rst condenser fan motor and provide positive start-up and operation at ambient temperatures to

-20 F. Additional condenser fan motors shall be controlled by ambient thermostats. All controls including the fan speed control

shall be factory mounted in an integral factory wired and tested control panel. The condensing unit shall be manufactured by the

manufacturer of the indoor unit.

Water/Glycol Cooled - The cooling coil shall be in an “A” frame arrangement to allow maximum coil surface in a small cabinet.

The large face area coil shall be constructed of

/2” O.D. copper tube with 12 ﬁ ns per inch of corrugated aluminum for maximum

heat transfer. Maximum face velocity shall be less than 500 feet per minute. The expansion valve shall be of the adjustable ther-

mostatic type with external equalization. The compressor shall be of the hermetic scroll type with complete overload protection
