2.5 OUTDOOR SHELTERED INSTALLATION
Many times a compressor must be installed outside due to jobsite conditions or limited space within a manufacturing facility. When this occurs there are certain items that should be incorporated into the installation to help ensure trouble free operation. These items have been listed below plus Figure
■The compressor should be on a concrete pad designed to drain water away. If the concrete pad is sloped, then the compressor must be leveled. In order to properly pull cooling air through the aftercooler, the base/skid must be sealed to the concrete pad.
■The roof of the shelter should extend a minimum of
4 ft (1.2 m) around all sides of the compressor to pre- vent direct rain and snow from falling on the unit.
■
■If the installation includes more than one compressor, the hot air exhaust should not be directed towards the fresh air intake of the second unit or an Air Dryer.
■If a standard machine is to be installed outside, the ambient temperature must never drop below 35°F (1.7°C).
■If ambient temperature drops below 35°F (1.7°C) to as low as
■Arrange the machine with the Intellisys con- troller/starter enclosure facing away from the sun as radiant heat can affect starter/lntellisys performance. Also direct sunlight and UV rays will degrade the membrane touch panel. This is not a warrantable situation.
■Power disconnect switch should be within line of sight and in close proximity to the unit. N.E.C. and local electrical codes must be followed when installing the power disconnect switch.
■Condensate drains must never be allowed to dump on the ground. Run to a suitable sump for future collection and disposal or separation of lubricant and water mixture.
■Incoming power connections must use suitable connectors for outdoor weather tight service.
■A minimum of 3 ft (.9 m) clearance must be allowed on all four sides of the unit for service access. If possible, access by a forklift and/or an overhead beam hoist should be kept in mind (for eventual service to airend or motor).
■If the area around the installation contains fine airborne dust or lint and fibers etc., then the unit should be purchased with the High Dust Filter Option and TEFC motors.
■If larger debris, such as leaves or trash, are blowing in the area, the Inlet Panel Filter Accessory should be purchased and added to the unit (ship loose item).
■Some type of protection such as a fence or security system, should be provided to prevent unauthorized access.
