6.1 Piping Instructions
WARNING
Piping between the compressor, accessory items and the sprinkler system must be at least ½" internal diameter to minimize
pressure drop from the compressor to system. Larger pipe size may be required by code and may be substituted with no
adverse effects.
NOTICE
If an air maintenance device (AMD) is used, allow sufficient distance between the compressor and AMD to ensure that the
maximum temperature at the AMD is 200°F or less.
NOTICE
All oilless compressors include a relief valve which is installed on the compressor. This valve will open at a preset value above
the pressure switch setting to prevent excess pressure in the event of a switch failure.
WARNING
A manual drain is provided on the bottom of each riser mount model with a tank. Moisture accumulated in the tank must be
drained weekly.
The compressor outlet piping should contain an accessible drain. As a minimum a manual drain may be used, but an automatic
drain is recommended to remove excess water.

NOTICE
Optional Flex Hose Installation Instructions:
An optional 30 inch Stainless Steel flex hose is available to aid the air compressor
installation. Part number 6872000000 should be ordered if desired. The flex hose
has ½" NPT male threads on both ends. Attach the flex hose to the air compressor
discharge or the air tank first. Then install a union to connect it to the piping system.
- This compressor is designed for non-lubricated service. Bearings are permanently
lubricated. Do not lubricate any part of the compressor or motor.
- Compressed air contains liquid water and is saturated with water vapor, which can
freeze when surrounding temperatures are lower than 32°F (0°C). Component selection
to minimize the effects of water vapor must be considered.
- Smaller line size must not be used and will restrict the compressor flow, lowering
capacity and causing the compressor/motor to work harder, which shortens
compressor/motor life. All piping connected to the compressor must be fully supported
and not transfer any loads to the compressor.
- An AMD must be used with all riser mounted tank units.
- Do not attempt to change the safety relief valve setting.
- Accumulation of condensed water in the system can cause corrosion of components
and reduction of system capacity.
- Warranty is void if a separate check valve is not installed to prevent water backflow to
compressor.
