SAFETY RECOMMENDATIONS
Disconnect all power sources before servicing.
When uncrating avoid contact with staples, nails, splinters and sharp edges. The sheet metal and coil
have sharp edges. Care must be taken when uncrating to prevent damage to the equipment and prevent
injury to the people working with it. Take time and care to be safe.
This equipment should be installed, started-up, and operated by certified and experienced commercial
refrigeration technicians. System piping must be in accordance with good refrigeration practice. Field
wiring must conform to the equipment specplate requirements, wiring diagram, and local and national
electrical codes. Use only copper conductors.
Read and study this complete installation and service manual before starting to work.
WORK SAFELY!
RECEIVING
A responsible person should inspect the crating or carton for possible shipping damage. Check each
shipment with the bill of lading to make sure all items are received in good condition. Report any short-
ages or damages to the delivering carrier. Damaged material is the responsibility of the carrier and a
freight claim should be filed with them.
DO NOT return damaged equipment to the manufacturer without prior approval.
APPLICATION OF ELECTRIC DEFROST EVAPORATORS
The evaporators covered in this bulletin are designed to operate at room temperatures below 35°F. LPE,
CSE and MSE models are recommended for room temperatures to -20°F, model CED and KED to -30°F,
and model HSE to -10°F. Model CED and KED are available with D type, direct drive fans as standard or
an optional PP type, high output cast aluminum pressure propeller fan blade.
Model LVE, with Low Air Velocity, is recommended for 28°F to 34°F rooms. The low velocity air flow
makes this unit ideal for meat holding rooms. Meat will hold longer and look better at 28 to 30°F than it
will at higher temperatures. Meat at this temperature is not frozen hard but it is firm, and therefore much
easier to handle, saw and cut.
System TD should be limited to 16° TD MAXIMUM on medium temperature systems and 11° TD MAXI-
MUM on low temperature systems. Most low temperature systems should be selected to operate at 8° to
10° TD. The greater the TD, the faster frost will accumulate on the coil requiring more frequent defrosts.
A wider TD also means reduced system capacity for a given room temperature and therefore, more com-
pressor run time.
HANDLING
Move evaporators with care. Use gloves to protect your hands. The sheet metal edges can be sharp.
Contact with fins should be avoided. Fins should be protected while the unit is being handled. The fins
are easily bent if hit. Damaged fins must be straightened. Use care when lifting not to damage the sheet
metal or copper connections. Do not lift against the center of the drain pan.
WORK SAFELY!
