Important Installation Notes - Thermo King MD-200 MT Manual De Instalación

Safety Precautions
• See "Safety Precautions" on pages v-vii prior to installing and
servicing this product.
Evaporator Location
• The best airflow is achieved when the evaporator is installed an
equal distance from each side wall.
• It is recommended that moving bulkheads not be allowed closer
than 1219 mm (48.00 in.) or 1 pallet from the evaporator outlet
(Detail A).
• The minimum clearance from the bottom of the evaporator to the
top of the cargo should be 101 mm (4.00 in.) (Detail A).
NOTE: This minimum clearance is required under the fan
intake area only and does not refer to the LOAD LINE.
• The evaporator should be located a minimum of 51 mm (2.00 in.)
from the truck wall (Detail B).
Defrost Drains
• The evaporator must be properly mounted to provide a slope
towards the drain. This is accomplished by adding one 3/8 in. and
one 3/16 in. washers on the drain side and only one 3/8 in. washer
on the other side at each mounting surface.
• Defrost drains must exit the evaporator at a 45° angle. Drains
should be 267 mm (10.50 in.) from the evaporator to the truck wall
(Detail C).
Door Curtains
• It is always recommended to use good quality insulated curtains
on all doors to limit the amount of warm, moist air from entering
the load space during door openings.

Important Installation Notes

Refrigerant Tubing and Electrical Wiring
• It is important to minimize the amount of time the tubes are
uncapped and open to ambient conditions. Always keep tubes
capped until ready to connect and solder.
• Check tubes and copper fittings for obstructions prior to assembly.
• It is also required that nitrogen or another inert gas be used to
purge the tubes while soldering. This prevents oxidation and
formation of scale inside tubes.
• Use 35% silver solder for joining all remote refrigerant tubes.
• Insulate suction and hot gas lines.
• All refrigeration tubes should be secured by clamps every 600 mm
(24.00 in.).
• All electrical harness should be secured by clamps or tie bands
every 600 mm (24.00 in.).
• Only one trough (W = Wall and C = Ceiling) is required
(Detail D & E).
• All dual evaporator installations require two suction tubes.
Door Switches
• Door switches are recommended for all multi-temp installations.
Door switches automatically turn off remote evaporators when the
corresponding door is opened. This avoids the entry of warm,
moist air into the load space.
