1.0 INSTALLATION
1.1 Location
A. Air compressor intake - Locate air compressor so that
contaminants potentially harmful to the dryer (e.g.
ammonia) are not drawn into the air system.
1. Location - locate the dryer so that the coolest
ambient air possible will be drawn across
the condenser.
B. Free air flow - Do not block either side of the
cabinet. Leave 12 inches (305 mm) on each side of
cabinet for free air flow.
1.2 Mounting
A. Models RHP50 and larger - Feet are supplied as
standard. Feet may be removed if floor or shelf
mounting is desirable.
B. Models RHP13 and RHP20 include wall mounting
bracket. See Illustration.
1.3 Piping connections
A. Air Inlet - Connect compressed air line from air
compressor to air inlet.
Refer to Serial Number Tag for maximum
working pressure. Do not exceed unit’s Maximum
Working Pressure.
NOTE: For maximum capacity, install unit in air
system at highest pressure possible (e.g. before
pressure reducing valves).
NOTE: For maximum capacity, install unit at coolest
compressed air temperature possible.
NOTE: Maximum inlet compressed air temperature:
120°F (49°C). If inlet air exceeds this temperature,
precool the air with an aftercooler.

B. Air Outlet - Connect air outlet to downstream
air lines.
C. By-pass piping - If servicing the unit without
interrupting the air supply is desired, piping should
include inlet and outlet isolation valves and an air by-
pass valve.
D. Drain - It is advisable to connect the automatic drain
outlet to the condensate drainage system.
NOTE: Drain discharge is at system pressure. Drain
line should be anchored to prevent whipping.
E. Water cooled models - cooling water inlet and outlet
1. Connect inlet water line to strainer.
2. Connect outlet piping.
NOTE: Strainer and water regulating valve are supplied on
water cooled models.
1.4 Electrical connections
A. Dryer is designed to operate on the voltage, phase,
and frequency listed on the serial number tag.
B. Dryer is supplied with an electrical cord and plug.
NOTE: Refrigeration condensing unit is designed to
run continuously and should NOT be wired to cycle
on/off with the air compressor.
