Installation Considerations
PIPING
1. An air lockout valve must be installed in the air line usually just before the filter-regulator-lubricator assembly to meet OSHA 29 CFR
1910.147 Lockout/tagout requirements.
2. From the lockout valve, connect at the In threaded opening of the filter-regulator. Try to maintain an appropriate pipe size throughout for
proper air flow. Connect the piping to the ports using teflon tape on the male threads only. Do not allow tape to enter the interior of the
filter-regulator-lubricator, valve, or air cylinder. Before applying air pressure, make sure the filter and regulator bowls are at least hand
tight.
3. Most approved pipe or hose can be used on the machine. Make sure the size is consistent throughout the system in order to avoid
restriction. Keep air runs as short as possible.
4. See enclosed filter-regulator-lubricator (FRL) assembly Manual No. KSL-208 for additional details.
All air components require clean air. Blow all lines clean of water, dirt, scale, etc., before making final connection.
Drain water from filter bowl regularly. Should this bowl refill in a short period of time, it may indicate the need for a
larger filter in the main air supply line or an air line dryer system. The air filter must be kept clean at all times. Never
operate the machine unless the air filter is clean and water is drained.
CAUTION
WIRING
National Electrical Code and NFPA 79 practices are usually followed for wiring the control system, which includes color-coding and the use of numbered
wire markers on
both ends of every wire
.
Color-coding is black for power circuits, red for 120-V AC control circuits, white for current-carrying ground
(commonly referred to as the neutral), and green for any equipment grounding conductor.
The size of wire depends on local ordinances. Number 14 stranded copper wire with an approved insulation is recommended.
Do not use solid wire.
Rigid, Sealtite, or any tubular connection media that complies with local ordinance is satisfactory. Complete wiring diagrams are provided for connecting
the control and components
