NOMENCLATURE

K TM 2 9 5 M A - S1 A

Design Version

Product Name

TM = Two Way Medium Prole Unit Cooler

X 100 = Nominal Capacity

(10°F TD, 60Hz), Btu/H

Evap Temp Range

M = Medium Temp (10 - 45°F), 6 FPI. L = Low Temp (-20 - 0°F), 6 FPI.

STANDARD FEATURES

• Heavy gauge textured aluminum cabinet

construction resists scratches/corrosion and minimizes weight for shipment, installation and service.

• Capacity up to 29,500 BTUH nominal.

• Dual refrigeration coils with two-way air distribution reduces air velocities to minimize

product dehydration.

• Air enters through fan and discharges two

ways out of each coil side.

• Low height compact size useable storage

space.

Unit Electrical Designaton.

S1 = 115/1/60 (air defrost models only) S2 = 208-230/1/60 S6 = 200-220/1/50

Defrost Type.

A = Air Defrost E = Electric Defrost G = Reverse Cycle w/ Electric Heater Pan

• Internally enhanced tube.

• Attractive and durable high - density

polyethylene fan guards.

• Standard PSC motors

• Hinged drain pan provides convenient access

for cleaning.

• Terminal board allows for easy electrical

connections.

• Reduced operating charge with 3/8” OD tubing

• Refrigerants R22, R404A, R507, R407C.

• Factory mounted solenoid valve, TXV and

Thermostat on air and electric defrost models.

• Fin material and special coatings.

OPTIONAL FEATURES

• Other options available - consult factory.

• ECM motors

‡ When using R407C, the factor above is to be used when matching to condensing units with Dew Point ratings. This factor will ensure that proper system balancing will occur to compensate for glide to t the application. If the system is sized correctly, one may expect a slight increase in system

capacity, along with slightly higher saturated suction temperatures.
