STEAM CONNECTIONS
Make Steam Supply and Steam Return connections as shown in Figure 2.
All horizontal runs must drain by gravity to respective Steam Header. Portions that connot drain
to Header must drain by gravity to machine, without water pockets.
Each Steam Header must drain, by gravity, to boiler or condensate return tank.
To prevent condensate draining from Steam Headers to machine, make steam connections (to
each respective Header) with a 12 inch or more vertical riser. Do not make steam connections to
a Header with a horizontal or downwardly facing tee or elbow.
Water pockets, or an improperly drained steam line (or header), will provide wet steam, causing
unnecessary wetting-out of buck padding.
Before installing check valve, trap and strainer, connect steam supply to machine from globe
valve (A). Open globe valve (A) to flush any foreign matter that may be in castings or pipes; open
globe valve (C) to flush foreign matter from return connections, then connect steam return from
valve (C) to machine with check valve, trap, and strainer as shown. If steam is gravity returned
to boiler, omit trap.
NOTE: For successful operation of machine, install trap as close to floor and as near machine as
possible. Inspect trap carefully for inlet and outlet marks and install according to manufacturer’s
instructions.
IMPORTANT: A separate steam trap must be used with each machine.
CAUTION
BEFORE OPERATING PANTS TOPPER, OPEN GLOBE VALVES IN STEAM LINES.
CHECK CAREFULLY FOR STEAM LEAKS, AND SEE THAT TRAP IS OPERATING PROP-
ERLY. UNDER NO CIRCUMSTANCES SHOULD MACHINE BE OPERATED UNTIL HOT.
OPERATING THE MACHINE COLD WILL WET THE NYLON BAG AND PADDING.
TO DRY A WET BAG OR PAD, DEPRESS THE “ON” MANUAL AIR SWITCH. AIR WILL
OPERATE CONTINOUSLY UNTIL “OFF” AIR SWITCH IS DEPRESSED.

ELECTRICAL CONNECTIONS
THE STANDARD Pants Topper has single phase motors. Before installation, check nameplates
on motor and control box for rated voltage and current specifications.
MAKE ELECTRICAL CONNECTIONS as indicated on wiring diagram attached to inside cover
of electrical junction box on Topper. Voltage and current of power line must be the same as the
Electrical Specifications of the motor, timers, relays, and solenoid.
FOR SINGLE PHASE CURRENT, connect power leads, L1 and L2, to an approved fused discon-
nect switch in power line.
TO CONNECT STANDARD, SINGLE PHASE MACHINE TO THREE PHASE CURRENT, con-
nect power leads, L1 and L2, to any two terminals of an approved fused disconnect switch in the
three phase power line.
FOR THREE PHASE CURRENT, connect power leads L1, L2, and L3 to the three terminals of an
approved fused disconnect switch in the three phase power line. The motor must rotate clockwise
when facing the belt and pulley. If rotation is incorrect, transpose any two leads connecting the
power line, and rotation of motor will reverse.
IMPORTANT: Consult your local electrical code before making any electrical connections; be
certain that the electrical installation conforms with all local requirements.
Always check wiring before closing the disconnect switch.

MAINTENANCE INSTRUCTIONS
IMPORTANT - Shut-off steam and electric power before performing Maintenance
Operations. Compressed air should also be cut off.
ELECTRIC MOTOR LUBRICATION:
SLEEVE BEARINGS: Motors with wool-packed sleeve bearings are oiled at the factory for two
years normal operation. After two years normal operation, add annually 1/2 teaspoon electric
motor oil or SAE-10 to each bearing. For 24 hours per day operation, add one teaspoon of oil
annually.
BALL BEARING: Motors having ball bearings are packed with sufficient grease for approxi-
mately TEN YEARS of normal operation. After ten years of normal operation, the bearings and
housing should be cleaned thoroughly. Repack each bearing and the cavity back of the bearing 1/
3 full with G. E. Ball Bearing grease.
CHECK VOLTAGE AND CURRENT:
Your Topper is wired for a given voltage and current as stamped on name plate. Motor, Timers,
Relays and Solenoid are for Single Voltage and Single current only. If machine is to be operated
on any voltage and current, other than apecified above, THE MOTOR, RELAYS, TIMERS AND
SOLENOID MUST BE REPLACED WITH UNITS CORRESPONDING TO THE VOLTAGE
AND CURRENT ON WHICH THEY ARE TO BE OPERATED.
GENERAL CLEANING:
Every six months remove top cover, rear panel, front panel, blower and belt guards and clean
thoroughly with a vacuum cleaner or air hose.
AIR LINE OIL LUBRICATOR (MODEL B)
Check Air Line Oil Lubricator and refill when less than half full. Use #10 weight oil.

Page 16
PANTS TOPPERBAG
KEEP BAG CLEAN. In operation, bag collects dust, lint, etc., greatly reducing its efficiency.
Launder bag at frequent intervals as determined by its soiled condition.
The Cissell Pants Topper bag has a double liner to extend pad life and to distribute steam uniformily.
REPAIR HOLES OR WORN SPOTS in bag to extend its useful life: REPLACE when worn be-
yond repair. A defective or worn bag will cause topper to operate unsatisfactorily. KEEP A SPARE
BAG IN STOCK.
CAUTION
Use only genuine CISSELL bags. The fabric for the Cissell Bag is
especially woven (and cut to an exact pattern) to give the correct porosity
and shape for proper steaming and drying. Rember, your CISSELL PANTS
TOPPER depends on the bag for proper operation.
Correct padding is necessary to obtain proper finishing. The Cissell buck pad is constructed of a
high, heat-resisting synthetic air foam, and perforated for rapid steaming and full air flow through
entire buck area. Replace a worn-out pad only with a Cissell perforated pad. Keep a spare pad in
stock. Do not use more than 1 pad.
RESEALINGEDGESFORSTEAM
&CONDENSATE LEAKS
When leak appears:
1. Remove top.
2. Using sealing compound Permatex #2 or
equivalent; (3 oz. tubes available from
factory).
Generously apply sealing compound
evenly along area of “Leak”. Allow
sealing compound to set and air dry for
approx. 2 hours before putting topper
back in service. Sealing compound will
not harden. If necessary, remove
switches from control box in Nose, when
fixing leaks in this area.

vertical position and align inside edge of pleat clamp with edge of buck crotch (F).
3. Apply pressure on arm knob (G) to provide pressure between pleat clamp (E) and buck. Hold pressure and
retighten cap screw (A) of arm expander.
4. With a thin card (H) check uniformity of pressure between edges of pleat clamp (E) and buck. If unequal,
rotate pleat clamp slightly to obtain a uniform pressure around all edges.
5. Re-tighten nut (B) of adjustable support. Note: Whenever tightening nut (B), do not apply pressure to knob
(G) or arm (C), as this will distrub the pleat clamp setting.
6. Top a pair of trousers.
A. If pleat clamp (E) makes an impression (too tight), loosen cap screw (B) and rotate adjustment
nut (J) counter-clockwise to reduce pressure. Retighten cap screw (B).
B. If pleat clamp does not hold pleat (too loose), loosen cap screw (B) and rotate adjustment nut
(J) clockwise to increase pressure. Retighten cap screw (B).
NOTE: Each pleat clamp must engage the padded buck uniformily with a slight pressure. Heavy pressure may
produce a hard finish and show seam imprinting. A very light pressure may allow pleat lay to shift during the air
cycle, and show wrinkles with an improperly shaped pleat. Adequate holding of the pleat lay during the air cycle
is aided by the surface texture of the pleat clamp and the buck cover.

5. Remove Rear Access Panel (H).
6. Remove Thrust Collar (I) from Blower Shaft (J).
7. Remove Blower Housing (K).
8. Remove Cut-Off Panel (L) and lift Blower
Wheel (M).
NOTE: To re-install, reverse procedure. When
placing Blower Wheel in Housing, be sure
blades are cupped towards rectangular opening.
Be sure that the two sheaves have the set
screws facing the outside.
BELT TENSION ADJUSTMENT AND PULLY ALIGNMENT
Improper belt tension or misalignment of pulleys may cause bearing and/or belt failures
The illustration at the right indicates recommended belt tension,
determined by grasping the belt as shown and when normal pressure
is applied, a deflection of approximately one inch will occur.
If the deflection is much more than indicated, slippage may occur
and wear out the belt.
If deflection is less than indicated, the belt is too tight and will shorten
the life of the bearings. Excessive tension will actually pull the shaft
through the oil film and allow metal to metal contact. Noisy blower
operation will also occur.
The illustration at the right shows the preferred method for checking
correct alignment of the pulleys. Excessive misalignment produces
increased belt wear and can produce lateral motion of the wheel and
shaft to the point that considerable noise can develop.
