MISE EN GARDE
• L'unité doit être installée par un installateur qualifié.
• Installer la sécheuse conformément aux instructions du fabricant et aux codes locaux.
• NE PAS installer une sécheuse avec des matériaux d'aération souples en plastique. Si un
conduit d'aération souple en métal (de type feuille mince) est utilisé, il doit être d'un type
spécifiquement mentionné par le fabricant de l'appareil comme convenable pour utilisation
avec sécheuses. Se reporter à la section sur la façon de connecter le système d'évacuation.
Les matériaux d'aération souples risquent de s'affaisser, ils s'écrasent facilement, et les
fibres et les peluches s'y accumulent. Ces conditions obstruent l'écoulement de l'air et
augmentent les risques d'incendie.

General Information
Once machine is installed, please be sure to complete
the following items:
This information is to be used when installing gas
tumblers in countries, and/or on gases, different than
the machine’s factory configuration. Tumblers are
supplied from the factory for operation on Natural Gas
1000 Btu/cu. ft. (8914 kcal/m3), or L.P. Gas 2500 Btu/
cu. ft. (22,250 kcal/m3) in the countries of GB/IE/PT/
ES/IT/GR/LU/CH. To install machines in any other
country, or on any other gas, requires some level of
modification.
●
Review and verify machine operation with
customer.
●
Leave all literature and a signed Declaration of
Conformity with customer.
●
Apply warning sticker on front panel of machine,
in language appropriate to country of sale
(included in literature packet).
Installing CE Gas Drying Tumblers
Burner orifices, stickers, block-open kits, regulator
springs and other parts needed for conversions are to
be ordered separately.
Models are built in two different configurations:
WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the
tumbler before servicing.
• Close gas shut-off valve to gas tumbler
before servicing.
• Close steam valve to steam tumbler
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the
tumbler is properly grounded.
W002
●
Regulated Natural Gas – Burner orifice is sized
for Natural Gas, second family, group H (E) at
20 mbar inlet pressure. Regulator/governor is
operational. Gas valve CAN be field-converted to
a non-regulating type.
●
Unregulated L.P. (Liquefied Petroleum) Gas –
Burner orifice is sized for L.P., third family,
group 3+ at 28.37 mbar inlet pressure. Regulator/
governor is blocked open. Gas valve CANNOT
be field-converted to a regulating type.
Serial plates supplied from the factory are configured
for the countries of GB/IE/PT/ES/IT/GR/LU/CH.
These instructions pertain to the situations when the
country of use or gas supply is different than that on
the serial plate.
Table 2 describes the different gases that are available
in different CE countries, and how the machines need
to be configured to operate with those gases. In the
CE, there are Natural Gas configurations that do not
allow for machine regulation, and L.P. Gas
configurations that must be regulated. For L.P. Gas,
third family B/P at 50 mbar, order Regulated Natural
Gas machines and convert according to Table 2.

Exhaust Requirements
WARNING
A drying tumbler produces combustible
lint. To reduce the risk of fire, the tumbler
must be exhausted to the outdoors.
W057
To reduce the risk of fire and accumulation
of combustible gases, DO NOT exhaust
tumbler air into a window well, gas vent,
chimney or enclosed, unventilated area
such as an attic wall, ceiling, crawl space
under a building, or concealed space of a
building.
Make-up air openings for a room containing
tumbler(s) and/or gas fired hot water heater or other
gravity vented appliances must be increased
sufficiently to prevent downdrafts in any of the vents
when all tumblers are in operation. Do not locate
gravity vented appliances between tumbler(s) and
make-up air openings. If it is necessary to duct makeup air to the tumbler(s), increase the area of the
ductwork by 25% to compensate for any restriction in
air movement.
Venting
WARNING
W059
Layout
Whenever possible, install tumblers along an outside
wall where duct length can be kept to a minimum, and
make-up air can be easily accessed. Elbows and long
vents tend to increase drying time. Construction must
not block the airflow at the rear of the tumbler. Doing
so would prevent adequate air supply to the tumbler’s
combustion chamber.
Make-Up Air
A tumbler is forced air exhausted and requires
provisions for make-up air to replace the air exhausted
by the tumbler.
IMPORTANT: Do not obstruct the flow of
combustion and ventilation air.
Make-up air openings should be as close to the
tumbler(s) as possible.
The required make-up air opening to the outside for
each tumbler is:
110 square inches (709 sq. cm)
for 25 and 30 pound models
144 square inches (928 sq. cm)
for 35 and 55 pound models
Make-up air openings with louvers will restrict
airflow. The opening must be increased to compensate
for area taken up by louvers.
70390001
To reduce the risk of fire due to increased
static pressure, we do not recommend
installation of in-line secondary lint filters
or lint collectors. If secondary systems
are mandated, frequently clean the
system to assure safe operation.
W749
IMPORTANT: Installing in-line filters or lint
collectors will cause increased static pressure.
Failure to maintain the secondary lint system will
decrease tumbler efficiency and may void machine
warranty.
For maximum efficiency and minimum lint
accumulation, tumbler air must be exhausted to the
outdoors by the shortest possible route.
Proper sized exhaust ducts are essential for proper
operation. All elbows should be sweep type. Exhaust
ducts must be assembled so the interior surfaces are
smooth, so the joints do not permit the accumulation
of lint. DO NOT use plastic or thin foil ducts - rigid
metal ducts are recommended. Use exhaust ducts
made of sheet metal or other noncombustible material.
DO NOT use sheet metal screws or fasteners on
exhaust pipe joints which extend into the duct and
catch lint. Use duct tape or pop-rivets on all seams and
joints.
Verify that old ducts are thoroughly cleaned out before
installing new tumbler(s).

Exhaust Requirements
NOTE: The maximum length of a flexible metal
duct must not exceed 2.4 m (7.87 ft.) as required to
meet UL2158, clause 7.3.2A.
WARNING
Improperly sized or assembled ductwork
causes excess back pressure which
results in slow drying, lint collecting in the
duct, lint blowing back into the room, and
increased fire hazard.
W355
NOTE: Exhaust ducts must be constructed of sheet
metal or other noncombustible material. Such
ducts must be equivalent in strength and corrosion
resistance to ducts made of galvanized sheet steel
not less than 0.0195 inches (0.495 mm) thick. Local
codes may require additional thickness.
Where the exhaust duct pierces a combustible wall or
ceiling the opening must be sized per local codes. The
space around the duct may be sealed with
noncombustible material. Refer to Figure 12.
IMPORTANT: For best performance provide an
individual exhaust duct for each tumbler. Do not
install a hot water heater in a room containing
tumblers. It is better to have the water heater in a
separate room with a separate air inlet.
Individual Venting
For maximum efficiency and performance, it is
preferred to exhaust tumbler(s) individually to the
outdoors.

Table 3
Example: A 12 inch (305 mm) diameter duct’s
equivalent length of 14 feet (4.3 m) of duct and two
90° elbows is:
Equivalent Length = 14 feet + (2) 90° elbows
= 14 feet + 14 feet + 14 feet
= 42 feet (12.8 meters)
With the tumbler in operation, airflow at any point in
the duct should be at least 1200 feet per minute (366
meters per minute) to ensure that lint remains airborne.
If 1200 feet per minute cannot be maintained, schedule
monthly inspections and cleaning of the ductwork.
IMPORTANT: At no point may the cross sectional
area of installed venting be less than the cross
sectional area of the exhaust outlet of the tumbler.
The exhaust duct must be designed so the static back
pressure measured 12 inches (305 mm) from the
exhaust outlet does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of the tumbler.
NOTE: Static back pressure must be measured
with the tumbler running.
The maximum allowable length venting of the same
diameter as the exhaust thimble is 14 feet (4.3 m) and
two 90° elbows or equivalent. If the equivalent length
of a duct required for an installation exceeds the
maximum allowable equivalent length, the diameter of
a round duct must be increased by 10% for each
additional 20 feet (6.1 m). Cross section area of a
rectangular duct must be increased by 20% for each
additional 20 feet (6.1 m). Refer to Table 3 to
determine equivalent venting.

Exhaust Requirements
Manifold Venting
While it is preferable to exhaust tumblers individually
to the outdoors, a main collector duct may be used if it
is sized according to Figure 14 and Figure 15. This
illustration indicates minimum diameters, which
should be increased if the collector length exceeds 14
feet (4.3 meters) and two 90° elbows. The diameter of
a round duct must be increased by 10% for each
additional 20 feet (6.1 meters). Cross sectional area of
a rectangular or square duct must be increased 20% for
each additional 20 feet (6.1 meters). Refer to Table 4
and Table 5 to determine equivalent ducting sizing.
The collector duct may be rectangular or square in
cross section, as long as the area is not reduced.
Provisions MUST be made for lint removal and
cleaning of the collector duct.
The vent collector system must be designed so the
static back pressure measured 12 inches (305 mm)
from the exhaust outlet does not exceed the maximum
allowable pressure specified on the installation sticker
on the rear of tumbler. Static back pressure must be
measured with all tumblers vented into the collector
operating.
32
NOTE: Never connect a tumbler duct at a 90° angle
to the collector duct. Refer to Figure 13. Doing so
will cause excessive back pressure, resulting in poor
performance. Never connect two tumbler exhaust
ducts directly across from each other at the point of
entry to the collector duct.
With the tumbler in operation, airflow at any point in
the duct should be at least 1200 feet per minute (366
meters per minute) to ensure that lint remains airborne.
If 1200 feet per minute cannot be maintained, schedule
monthly inspections and cleaning of the ductwork.

Gas Requirements
The following must be furnished and installed by the
customer for the gas service line to each tumbler.
Refer to Figure 16.
WARNING
To reduce the risk of fire or explosion, DO
NOT CONNECT THE GAS LINE TO THE
TUMBLER IF THE GAS SERVICE IS NOT
THE SAME AS THAT SPECIFIED ON THE
TUMBLER SERIAL PLATE! It will first be
necessary to convert the gas burner
orifice and gas valve. Appropriate
conversion kits are available.
W060
IMPORTANT: Any product revisions or
conversions must be made by the manufacturer’s
authorized dealers, distributors, or local service
personnel.
IMPORTANT: The tumbler must be isolated from
the gas supply piping system by closing its
individual manual shut-off valve during any
pressure testing of the gas supply piping system at
test pressure equal to or less than 0.5 psig
(3.45 kPa, 34.5 mbar).
IMPORTANT: The tumbler and its manually
operated appliance gas valve must be disconnected
from the gas supply piping system during any
pressure testing of that system at test pressures in
excess of 0.5 psi (3.45 kPa, 34.5 mbar).
IMPORTANT: The installation must comply with
local codes or, in the absence of local codes:
●
with the latest edition of the “National Fuel
Gas Code,” ANSI Z223.1/NFPA 54 in the
U.S.A.,
●
with CAN/CSA-B149.1 or Natural Gas and
Propane Installation Code in Canada,
●
and Australian Gas Association/Australian
L.P. Gas Association requirements in
Australia.
Obtain specific gas service pipe size from the gas
supplier. Refer to Table 6 for general pipe size.
●
Sediment traps
●
Shut-off valves
●
Supply pressure taps
It is important that equal pressure be maintained at all
tumbler gas connections. This can best be done by
installing a one inch (25 mm) pipe gas loop. Refer to
Figure 17.
WARNING
To reduce the risk of fire or explosion, if
the tumbler is to be connected to Liquefied
Petroleum (L.P.) gas, a vent to the
outdoors must be provided in the room
where the tumbler is installed.
W062
NATURAL GAS line pressure must be maintained at
6.5 water column inches (1.62 kPa), with no less than
5 water column inches (1.24 kPa) and no more than
10.5 water column inches (2.61 kPa), with all gas
appliances running (tumblers, water heaters, space
heaters, furnace, etc.). An in-line pressure regulator
may be required if the line pressure exceeds 8 water
column inches (2.0 kPa) with all gas appliances
running.
LIQUID PETROLEUM GAS (L.P.) line pressure must
be maintained at 11 water column inches (2.74 kPa),
with no less than 10 water column inches (2.49 kPa)
and no more than 13 water column inches (3.23 kPa),
with all gas appliances running (tumblers, water
heaters, space heaters, furnace, etc.).
For converting Non-CE models from Natural Gas to
L.P. Gas:

Gas Requirements
Turn on gas and check all pipe connections (internal
and external) for gas leaks with a non-corrosive
detection fluid. Purge air in gas service line by
operating the tumbler in the drying mode. If burner
does not light and unit goes into lockout, open and
close the door and restart. Repeat these steps until
burner ignites. Use pipe compound, resistant to
actions of L.P. Gas, on all pipe threads.

To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the tumbler
before servicing.
• Close gas shut-off valve to gas tumbler
before servicing.
• Close steam valve to steam tumbler
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the
tumbler is properly grounded.
W002
To reduce the risk of fire and electric
shock, check with a qualified serviceman
for proper grounding procedures. Improper
connection of the equipment grounding
conductor may result in a risk of electric
shock.
W068
To reduce the risk of fire and electric
shock, if electrical supply is coming from a
three phase service, DO NOT connect a
“High Leg” or “Stinger Leg” to a single
phase machine. On a three phase machine,
if there is a “High Leg” or “Stinger Leg” it
should be connected to L3.
W069
Grounding Instructions
NOTE: To ensure protection against shock, this
tumbler MUST be electrically grounded in
accordance with the local codes or, in the absence of
local codes, with the latest edition of the National
Electrical Code ANSI/NFPA No. 70. In Canada the
electrical connections are to be made in accordance
with CSA C22.1 latest edition Canadian Electrical
Code, Part I, and/or local codes.
This tumbler must be grounded. In the event of
malfunction or breakdown, grounding will reduce the
risk of electric shock by providing a path of least
resistance for electric current. This tumbler must be
connected to a grounded metal, permanent wiring
system; or an equipment grounding conductor must be
run with the circuit conductors and connected to the
appropriate ground location.
●
Metal conduit and/or BX cable is not considered
ground.
●
Connecting the Neutral from the electrical
service box to the tumbler ground screw does not
constitute a ground.
●
A dedicated ground conduit (wire) must be
connected between the electrical service box
ground bar and the tumbler ground screw.
WARNING
All electrical connections should be made
by a qualified electrician.
To reduce the risk of electrical shock, deenergize the electrical circuit being
connected to the tumbler before making
any electrical connections. Never attempt
to connect a live circuit.
W070
CAUTION
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause
improper and dangerous operation. Verify
proper operation after servicing.
W071
For CE Models Only
All manually operated models are factory-equipped
with an emergency stop button on the front panel. If
the emergency stop function is desired on coinoperated models, an external emergency stop button
may be installed as specified on the machine wiring
diagram.
NOTE: Activation of the emergency stop button
stops all machine control circuit functions, but
DOES NOT remove all electrical power from
machine.

Electrical Requirements
Connecting Electrical Service
The following steps outline the procedure for
connecting electrical service to the tumbler.
●
●
●
3 Phase Models – Each tumbler must be
connected to its own individual branch circuit
breaker, not fuses, to avoid the possibility of
“single phasing” and causing premature
failure of the motor(s).
Electrical service must be connected using the
appropriate permanent rigid metal conduit
system.
Service conductors must be copper only.
For an existing service, determine your service voltage
and conductor amperage. Carefully review the tumbler
serial plate ratings and Electrical Requirements
section of this manual. If service is inadequate it must
be upgraded by a qualified electrical contractor. Never
connect an improper or inadequate service to any
machine.
Configuring Your Tumbler for Other
Service Voltages
Several gas and steam tumbler models have been
designed to be field convertible to other service
voltages. Refer to Table 8 for these models:
If your Serial Plate
voltage is:
Your tumbler can be
converted to the
following voltages:
120 Volt/60 Hertz/
1 Phase
208-240 Volt/60 Hertz/
1 Phase
200-220 Volt/60 Hertz/
1 Phase
100 Volt/60 Hertz/
1 Phase
200 Volt/50 Hertz/
1 Phase
100 Volt/50 Hertz/
l Phase
240 Volt/60 Hertz/
3 Phase
200-208 Volt/60 Hertz/
3 Phase
380 Volt/50 Hertz/
3 Phase
400-415 Volt/50 Hertz/
3 Phase
If tumbler requires conversion for use on another
service voltage, complete the steps detailed in the
Conversion Instructions section prior to connecting
service to machine.
If tumbler does not require conversion or has been
converted according to the Conversion Instructions
section of this manual, continue with step 1.
NOTE: The wiring diagram is located inside the
junction or contactor box.
1. For new service, install a circuit breaker or fused
disconnect of proper voltage and current rating as
close to each tumbler as possible.
2. Route service conduit from service breaker panel
or disconnect panel to tumbler service connection
box. Conduit routing should not obstruct access
for maintenance or servicing. Refer to Service/
Ground Location.
3. Pull conductors through conduit and attach to
circuit breaker and ground connection. Secure
service ground wire to the grounding screw or
lug. Attach service conductors to appropriately
labeled positions on the terminal block. Make
sure all connections are secure.
4. Complete ferrite installation instructions for all
gas and steam OPL Micro.
5. Check electrical service phase sequence (3 Phase
models only) as follows:
a. Energize the electrical service and
momentarily start the tumbler. Check the
direction of cylinder rotation. If the cylinder
rotates clockwise as viewed from the front,
the phase sequence is correct. If the cylinder
rotates counterclockwise, proceed with step b.
b. Disconnect power to machine, disconnect and
reverse the L1 and L2 connections on the
terminal block.
Table 8
NOTE: Electric models are not field convertible
and must be connected to service specified on serial
plate.

Ferrite Ring Installation
To Install:
Gas and Steam OPL Micro Control Models Only
The ferrite ring provided in the literature packet must
be installed over the power leads during connection of
electrical service. The ferrite protects the sensitive
electronic controls from destructive electrical
disturbances which may be present on power lines to
the machine. Failure to properly install the ferrite ring
may result in damage to the electronic controls and
will void control warranty.
1. Immediately after connection of power leads and
before applying power to machine, locate each of
the incoming service leads including ground.
2. Snap the ferrite ring closed over all of the service
leads inside of the control tray as shown. It is
important that the ferrite ring be installed inside
the control tray. Refer to Figure 19. Do not install
the ferrite outside of the box or other area. Make
sure that service leads are in the center of the
ferrite before closing the ring so as not to pinch
or damage leads.

Steam Requirements
NOTE: Machines require a constant 80 to 100 psig
(5.62 to 7.03 kg/sq. cm) stream service for optimum
operation. The maximum allowable steam pressure
for use with 60 Hertz or 50 Hertz tumblers is
125 psig (8.6 bar). In no case may the pressure
exceed the above value.
Obtain specific steam service pipe sizes from the
steam system supplier or a qualified steam fitter.
●
Refer to Figure 20 for proper steam pipe
configurations.
●
To prevent condensate draining from headers to
tumbler, piping should have a minimum 12 inch
(305 mm) rise above respective header. Do not
make steam connection to header with a
horizontal or downward facing tee or elbow.
●
●
Whenever possible, horizontal runs of steam
lines must drain, by gravity, to respective steam
header. Water pockets, or an improperly drained
steam header, will provide wet steam, causing
improper operation of tumbler. If pockets or
improper drainage cannot be eliminated, install a
bypass trap to drain condensate from the low
point in the steam header to the return.
In both steam supply and steam return line, it is
recommended that each have a pipe union and
shut-off valve. This will enable you to disconnect
the steam connections and service the tumbler
while your laundry facility is in operation.
●
Connect the steam solenoid valve to the related
steam coil inlet connection with nipples, flex
hoses, unions and tee.
●
Strainers may require cleaning due to materials
from hoses or pipes.
●
Install vacuum breaker (optional), bucket trap
with built-in strainer and check valve. For
successful operation of tumbler, install trap 18
inches (457 mm) below coil and as near to the
tumbler as possible. Inspect trap carefully for
inlet and outlet markings and install according to
trap manufacturer’s instructions. If steam is
gravity returned to boiler, omit trap but install
optional vacuum breaker and check valve in
return line near tumbler. Gravity return requires
entire return plumbing be below steam coil
outlet.
●
Install union and shut-off valve in return line and
make final pipe connections to return header.
52
NOTE: To prevent water hammering, route return
lines below outlets of steam coils.
Piping Recommendations
●
Trap each steam coil individually. Always keep
the trap clean and in good working condition.
●
When tumbler is on the end of a line of
equipment, extend header at least 4 feet (1.2 m)
beyond tumbler. Install shut-off valve, union,
check valve and bypass trap at end of line. If
gravity return to boiler, omit trap.
●
Insulate steam supply and return line for safety of
operator and safety while servicing tumbler.
●
Keep tumbler in good working condition. Repair
or replace any worn or defective parts.
WARNING
All system components must have a
125 psig (8.6 bar) working pressure.
Shut-off valves must be installed upstream
of the steam solenoid valve and
downstream of each steam trap so
components can be isolated for
maintenance or emergency purposes.
All components (solenoid valve, traps)
must be supported to minimize loads on
the tumbler steam coil connections.

Steam Requirements
Installing Steam Trap and Making
Condensate Return Connections
The steam trap must be installed and the coil outlet
connections must be connected to the condensate
return lines. The following steps outline the procedure
for installing the steam trap and connecting the
condensate return lines. Refer to Figure 20 for typical
installations.
1. Use flexible lines between steam inlet solenoid
and steam coils, as well as outlet between steam
coil and traps.
2. If necessary, install a strainer at the end of each
flexible hose.
WARNING
The flexible steam hoses connecting the
coil outlet connections and steam traps
must have a minimum of 125 psig
(pounds per square inch gauge) (8.79 kg/
sq. cm.) working pressure. A shut-off
valve must be installed downstream from
each steam trap so the condensate return
line can be isolated in event a steam trap
requires maintenance.
Each steam trap must be supported so
minimum load is exerted on the coil outlet
connection.
3. Install a steam trap to each strainer.
W066
IMPORTANT: Steam trap must be installed a
minimum of 18 inches (457 mm) below the steam
coil outlet connections.
4. Install a shut-off valve to each steam trap.
5. Connect to the condensate return lines.
6. For steam solenoid valve wiring connections,
refer to Wiring Diagram supplied with tumbler.

Adjustments
Loading Door Switch
Airflow Switch
The door switch should be adjusted so the cylinder
stops when door is opened 2 inches (51 mm) plus or
minus 0.25 inch (6 mm). This switch is a normally
open switch and is closed by the hinge cam when the
door is closed. If adjustment is required, refer to
Figure 21 and proceed as follows:
The airflow switch is set at the factory for proper
operation. No adjustment necessary.
1. Close door and start tumbler, slowly open loading
door. Cylinder and heat system should shut off
when door is open 2 inches (51 mm) plus or
minus 0.25 inch (6 mm).
2. Slowly close the loading door. When door is
2 inches (51 mm) from being fully closed, the
door switch actuating bracket (located on the
door) should depress the button and the switch
arm with an audible “click.”
3. If the actuating bracket does not operate the
switch at the appropriate door closure, bend the
actuating switch arm in or out to achieve proper
actuation.
The airflow switch operation may be affected by
shipping tape still in place, lack of make-up air, or an
obstruction in the exhaust duct. These should be
checked and the required corrective action taken.
WARNING
The tumbler must not be operated if the
airflow switch does not operate properly.
Faulty airflow switch operation may cause
an explosive gas mixture to collect in the
tumbler.
W072
IMPORTANT: Airflow switch vane must remain
closed during operation. If it opens and closes
during the drying cycle, this indicates insufficient
airflow through the tumbler. If switch remains
open, or pops open and closed during the cycle, the
heating system will shut off. The cylinder and fan
will continue to operate even though the airflow
switch is indicating insufficient airflow.
NOTE: To properly mount the airflow switch
bracket, or in case of a load not drying, the airflow
switch bracket may need to be checked for proper
alignment. Be sure the locator pins are securely in
their respective holes before tightening the bracket
mounting screws. This will assure proper
alignment of the airflow switch arm in the channel
of the airflow switch bracket and prevent binding
of the arm.

Adjustments
Door Strike
The door strike must be adjusted to have sufficient
tension to hold loading door closed against force of the
load tumbling against it. There is proper adjustment of
pull force when 8 to 15 pounds (35.6 N – 66.7 N) is
required to open door.
If adjustment is required, refer to Figure 22 and
proceed as follows:
To adjust, open door, loosen acorn nut, and turn door
strike screw in or out as required. Retighten acorn nut.
