COLD WEATHER HEATER PACKAGE
To preheat critical components and lubricant sumps during a
cold weather shutdown, an optional Cold Weather Heater
Package is available. The package contains the following
heaters:
See Figure 3-19
• Battery pad heaters (1): two, 75 watts each.
• Engine coolant heater (2) 1,000 watt.
• Engine oil heater (3): 300 watts.
• Hydraulic tank heater (4): 2,000 watt.
The hydraulic tank heater is designed to keep the
hydraulic oil temperature 30°F (17°C) warmer than the
ambient air temperature.
A thermostat (located under heater cover) is factory-set
to turn the heater on at 60°F and off at 80°F (16°C and
21°C).
• Control console air heater (6): 125 watt.
The thermostat (5) turns on the control console air
heater at 50°F and off at 60°F (10°C and 16°C).
The heater package is powered by the AC Electric System
described on page 3-51
.
Refer to Figure 3-18
for identification of the heater circuit
breakers.
NOTE When operating below –30°F (–34°C), the heater
package may not provide adequate protection.
Contact your Manitowoc dealer for
recommendations.
To turn the heaters ON, see Turning On AC Components on
page 3-51.
To turn the heaters OFF, see Turning Off AC Components
on page 3-51.
CAUTION
Avoid Machinery Damage
Operating in an arctic climate without heaters can
damage machinery during cold weather start-up due to
lack of lubrication.
When the MLC165-1 is operated in an arctic climate,
defined as an outside temperature continuously below
0°F (–18°C) and –30°F (–34°C), the crane should be
equipped with heaters identified in this section and
lubricated with the lubricants listed in the Lubrication
Guide.
CAUTION
Avoid Machinery Damage
When the ambient temperature is above 30°F (–1°C) or
when the engine is running, do not turn on the engine oil
pan or coolant heaters. Doing so may result in
overheating because they are not supplied with a
thermostat.
