OIL RESERVOIR DRAIN
- The oil drain is piped from the bottom of the reservoir to the side of the base.
This drain is approximately 4.50 inches (115 mm) above the floor level. If this is not sufficient to
conveniently drain the oil, other methods are:
1.
Elevate the compressor unit on a suitable structure to obtain the desired drain height.
If the compressor unit base is raised above floor level, the space between the
floor and the base bottom must be closed with solid material all around to
prevent main motor from running hot.
2.
Construct an oil sump or trough below the floor level and pump or bail the drained oil.
3.
Pump oil from the reservoir filler opening or drain to a container.
ENCLOSURE
- The compressors, electric motors and control devices are mounted inside the compressor
package enclosure. Service doors are provided for maintenance access. Be sure to allow enough space
around the unit for the doors to open completely.
To remove the enclosure doors, open the door and lift it up slightly to disengage the hinges.
Ducting may be required on air-cooled machines.
INSTALLATION FOR COLD WEATHER OPERATION -
It is recommended that the unit be installed
inside a shelter that will be heated to temperatures above freezing (40
°
F, 5
°
C). This will eliminate many
of the problems associated with operating units in cold climates where freezing rain, drifting snow,
freezing condensate and bitter cold temperatures are encountered.
Do not operate the compressors with the fan or coupling guard removed.
Exposed fan and couplings may cause personal injury.
