It is essential when installing a new dryer [3], to review the total air
system. This is to ensure a safe and effective total system. One item
which should be considered is liquid carryover. Installation of air dryers
[3] is always good practice since properly selected and installed they
can reduce any liquid carryover to zero.
Piping should be at least as large as the discharge connection of the
equipment. All piping and fittings should be suitably rated for the
operating pressure.

ELECTRICAL

CAUTION
This procedure should only be carried out by a qualified
electrician, electrical contractor or your local Ingersoll Rand
Distributor or Air Center.
The dryer should be properly grounded / earthed in accordance with
Local and National Code requirements..
Installation of this dryer must be in accordance with recognized
electrical codes and any local Health and Safety Codes.
The dryer must have its own isolator situated adjacent to it. The fuse
protecting the circuit and the dryer must be selected in accordance with
local and national code requirements on the basis of the data provided
in the general information section
Feeder cables should be sized by the customer/electrical contractor to
ensure that the circuit is balanced and not overloaded by other
electrical equipment. The length of wiring from a suitable electrical feed
point is critical as voltage drops may impair the performance of the
dryer.

It is good practice to locate by–pass piping close to the dryer and to
install line filters [4].
IMPORTANT: The drain line must slope downward from the base to
work properly. For ease of inspection of the automatic drain trap
operation, the drain piping should include an open funnel.
CAUTION
The use of plastic bowls on line filters and other plastic air line
components without metal guards can be hazardous. Their safety
can be affected by either synthetic coolants or the additives used
in mineral oils. From a safety standpoint, metal bowls should be
used on any pressurized system.
NOTICE
Do not use the dryer to support the piping.
Feeder cable connections to incoming terminals L1–L2–L3 should be
tight and clean.
The applied voltage must be compatible with the data plate ratings.
NOTICE
The control circuit transformer has different voltage tappings.
Ensure that these are set for the specific applied voltage prior to
starting.
A hole is provided for incoming power connection. If it is necessary to
make a hole in the control box in a different location, care should be
taken to not allow metal shavings to enter the starter and other electrical
components within the box. If another hole is used, the original hole
must be blocked off.
The feeder cable must be suitably glanded into the electrical box to
ensure that dirty air does not by–pass.
On completion of electrical installation, check that fan motor rotation is
correct. Cooling air must discharge upwards.
