3.2 Electrical Installation
Electrical connections should be made by a qualified electrician in accordance with all applicable
codes or requirements. Use a separate branch circuit to power each machine. Do not share circuits
with lighting or any other equipment.
A shielded liquid tight or approved flexible conduit with proper conductor of correct size installed
in accordance with National Electric Code (USA) or other applicable codes is required. The connec-
tion must be made by a qualified electrician using the wiring diagram provided with the machine.
For personal safety and for proper operation, the machine must be grounded in accordance with
state and local codes and in the USA in accordance with the National Electric Code, article 250-96.
The ground connection must be to a proven earth ground, not to conduit or water pipes.
Do not connect the ground to the neutral (N) leg at the terminal strip (if so equipped).
If a DELTA supply system is used, the high leg should be connected to L3, since control voltage is
derived from L1 and L2.
Insure that the control transformer taps are connected in accordance with the incoming line volt-
age. Verify connections as shown on the schematic with each machine.
Note:
Ensure that all power connections are tight. Loose connections will
cause burned wires and contactors on electrically heated machines.
Check the electrical connections at the incoming power terminal block,
contactors, and heating elements at installation, after the first week of
operation, and quarterly thereafter. Failure of switchgear due to negli-
gence in this area is not covered under any warranty!

3.3 Gas Connection
3.3.1 Gas Supply Line
•1” IPS pipe is recommended.
•1” approved tubing is acceptable for lengths under 25 ft (6.1 m) if local codes and gas supplier
permit.
•Must include 1/8” NPT minimum plugged tapping accessible for test gauge connection,
immediately upstream of the gas connection to the dryer (see figure 3.8 on page 15).
•Must include a shutoff valve:
An individual manual shutoff valve must be installed within 6 feet (1.8m) of the equip-
ment in accordance with the National Fuel Gas Code, ANSI Z223.1. The location should
be easy to reach for opening and closing.
3.3.2 Gas Supply Connection Requirements
There are many methods by which the DE series dryer can be connected to the gas supply. Fol-
lowing are some guidelines for methods of connection.
Option 1:
Flexible stainless steel gas connector:
If local codes permit, use a new flexible stainless steel connector (Design certified by the American
Gas Association or CSA International) to connect between the dryer and the gas supply line. Use
15

an elbow and a 1” flare x 1” NPT adapter fitting between the stainless steel gas connector and the
gas inlet of the machine as needed to prevent kinking.
Option 2:
Other approved piping:
Lengths under 25 feet (6.1m) use 1” approved tubing.
Lengths over 25 feet (6.1m) should use larger piping.
Pipe joint compounds that resist the action of gas must be used. DO NOT USE TEFLON R /PTFE
TAPE.
IMPORTANT: Be certain the dryer is configured for the type of gas being used. The gas type is
shown on the serial sticker on the electrical panel of the unit.
Inlet Pressure
Use a manometer to verify that the inlet pressure meets the following requirements:
Natural Gas service must be supplied at 4-14 inches of water column pressure.
LP Gas service must be supplied at 11-14 inches of water column pressure.
If the incoming gas pressure exceeds the above, install a locally obtained gas regulator that has
sufficient BTU capacity to supply the machine (Maxitrol 325-5AL for up to 300,000 BTU, 327-7L
for up to 900,000 BTU or equivalent). A chattering gas valve indicates improper line pressure, not
a faulty gas valve.
Manifold Pressure (Secondary)
Be sure to check the manifold pressure. Use a manometer to verify that the manifold pressure
matches the information on the serial sticker and the type of gas being used. A separate gas
regulator (locally obtained) must be installed if the incoming line pressure is greater than 14 inches
water column pressure.
1. Connect the manometer to the pressure connection on the gas valve (disconnect gas service).
2. Restore gas service, and determine the pressure while the burner is ignited. The pressure
must match the indicated manifold pressure on the serial sticker.
Gas Conversion Notice: Do not connect a machine configured for Natural Gas to LP Gas service or
vice-versa without a qualified service technician doing a proper conversion. After the reconfigura-
tion is complete, the manifold pressure must be verified. See Section 8.1 on page 39 for conversion
details.
3.4 Steam Connection
For best results, operate with a steam pressure of 90 psi (6.2 bar). The steam inlet and return are
located on the rear of the machine.
16

Important: Insulate all steam and return lines for the safety of the operator and service technician.
Important: All steam components must be rated for a minimum of 200 psi (14 bar) working pres-
sure. Shut off valves must be installed upstream of the steam inlet, and downstream of the steam
trap so that the equipment can be isolated for maintenance or emergency.
Important: Support all steam lines and components to minimize the load on the steam connections
to the dryer.
Obtain steam service piping from a steam system supplier or a qualified steam fitter.
Use a minimum of 12 inch (300mm) rise above the header to prevent condensate from draining
into the dryer. Do not make a steam connection to the header with a horizontal/downward facing
tee or elbow.
Wherever possible, horizontal runs of steam lines must gravity drain to the steam header. Water
pockets or improperly drained headers will yield poor results due to wet steam.
Install a union and valve in the steam supply and return lines for ease of service.
For best performance, install an inverted bucket trap with strainer and a check valve. Avoid ther-
mostatic traps. For best results, install the trap at least 18 inches (450mm) below the inlet and as
close to the machine as possible. Install the trap according to the instructions with the unit, noting
the steam flow direction. If the steam is gravity returned to the boiler, install a vacuum breaker
and check valve in the return line near the machine. Note that all return plumbing must be below
the return inlet.
To prevent eventual water hammer, route all return lines below steam outlets.

3.5 Steam Damper
The DE-120 and DE-170 are manufactured with a pneumatic (piston) damper system which re-
quires an external supply of compressed air. The air connection is made to the steam damper
solenoid valve which is located at the rear inner top area of the dryer just above the electric service
relay box. See Table 3.2 on page 18 for details.
