Type I Reassembly
!
WARNING
Description
TYPE I: The compressor with its terminal box is removed and placed on a skid as a separate package.
The suction piping is removed and shipped loose. All other piping will be disconnected from the
compressor and remain attached to the vessel stack, where possible. Wiring and sensors to the
compressor will be disconnect ed, rolled up and tied to the control pane ls. The remaining loose parts
will be packaged in a separate crate.
1. Block-offs will cover all openings on the compressor and vessels.
2. The compressor and vessels will receive a 5-psi helium holding charge.
3. The compressor will not be insulated at the factory. An insulation kit will be shipped with the unit
and will also include a container of adhesive.
4. The unit vessel stack will be insulated at the factory.
5. This unit will be tested with a full refrigerant charge at the factory and the charge will be removed
after testing.
6. Refrigerant will not be shipped with the unit and must be secured locally and furnished and
installed by the installer.
7. Bracket and cable kit will be included for all unit-mounted starters and/or cableway for mini-
cabinet starters.
8. All free piping ends will be capped.
9. Touch-up paint and stick-on wire ties will be included.
10. Lubricant will be shipped in containers from the factory.
11. The starter will ship loose.
12. All field piping connections will be Victaulic, flanged, O-ring face seal or copper brazing.
13. The unit control panel and compressor control panel will be attached to the unit with loose sensor
wires tied up behind the panel.
Reassembly Steps
NOTE: Additional instructions may be shown on the assembly drawings.
1. Mount the compressor on the stack. Be careful to avoid damaging lines already mounted on the unit.
Mounting bolts, washers and nuts are shipped loose. Leave the mounting bolts loose until the suction
and discharge lines are installed and aligned.
During assembly, bolts holding block-off plates (motor cooling connection, for example), are used for
reassembly of the component. See Figure 1 or Figure 2 for the location and description of the blockoffs.
2. Do not remove block-offs until ready to install piping. The compressor and vessels have a Schrader
valve on their block-off plates to be used for relieving the helium holding charge.
Remove compressor and vessel holding charge through the Schrader valve in the block-off plates
before attempting to loosen any fittings on them. Failure to do so can cause severe bodily injury.
3. Install the suction and discharge piping (see Figure 3). Before tightening the Victaulic couplings,
position the suction and discharge piping so that the compressor can be aligned to give the best fit-up.
When this is achieved, secure the compressor mounting bolts and proceed with installing the Victaulic
couplings using a light coating of Victaulic lubrication.
IM 1128-1 Field Installation Procedure 5
4. Install the liquid injection line (see Figure 4). The liquid injection line is attached to the condenser
and has shipping straps securing it to the evaporator and condenser. It, and the compressor, each have
a block-off. Note that any given injection line may be configured somewhat differently than shown on
the drawing.
5. Install the motor cooling line (see Figure 5) using the same procedure as the liquid injection line.
6. Install the motor drain line (see Figure 6) using the same procedure as the liquid injection line.
7. Piping for the optional hot gas bypass is shipped mounted on the unit except for models WSC100,
WSC113 and WSC126 with vessel stacks sizes E36C30, E36C36, E42C36, E42C42, E48C42 and
E48C48. These units have the piping assembly shipped loose for field mounting. See Figure 7.
8. Install the compressor lubrication lines. There are four lines as shown in Figure 8:
a. Thrust pump return, injects lubricant from the compressor thrust pump (thrust bearing) into
the lubricant supply line.
b. Oil drain, drains lubricant from the compressor to the sump.
c. Vent line, vents refrigerant from the sump back to the compressor suction.
d. Oil supply, supplies lubricant from the pump in the sump to the compressor.
There is a variety of fitting types employed on the oil lines. Reconnect the compression fittings, bolt
on the flanges using new gaskets furnished, and re-sweat the sweat connections.
9. Install the four-way solenoid on the compressor suction housing.
10. Install compressor wiring using Figure 9 (including notes) as a guide. Figure 9 shows connections for
both Type I and Type II arrangements. Only the connections listed below are required to be made for
Type I. The wire end that has been disconnected, and its attachment point on the compressor, will
each have a label attached (VC for the vane close switch, for example) for matching purposes.
a. Guardistor, G1 (and G2 on some units), terminal box located on side of motor housing.
b. Compressor heaters, CP1 (and CP2 on some units), located on the bottom of the compressor.
c. Vane load/unload solenoids, SA and SB, located on the four-way solenoid assembly.
d. Vane close switch, VC, located on compressor next to the discharge housing.
e. Vane open switch, VO, located on suction end of compressor.
f. High pressure switch, HPS, located on compressor discharge nozzle.
11. If the unit has been ordered with a starter or VFD as unit mounted, brackets for mounting it and
interconnection cables to the compressor motor will be included as ship loose items. Control wiring as
shown in Figure 9 and Figure 13 (field wiring diagram), will also be required. The field wiring
diagram located on the control panel door should also be consulted as it will be current. If the unit has
a free standing starter, use normal field procedures for mounting and wiring.
Normal procedure of leak testing, triple evacuation, and charging with refrigerant and lubricant must
be followed prior to the start up procedure.
12. Insulate the compressor motor, suction line, and other miscellaneous areas with the included insulation
and adhesive after leak testing. See Field Insulation Guide on page 29.
This completes the reassembly procedure.

Type II Reassembly
Description
TYPE II: The compressor with its terminal box is removed and shipped on a skid. The condenser,
evaporator, oil sump, oil cooler and tube sheet support plates will remain connected only by their
attachment bolts, ready for field disassembly on site and subsequent r eassembly in the building. All
wiring and piping that interconnects the components will have been removed and will require
reinstallation. The loose parts will be packaged in a separate crate.
1. Block-offs will cover all openings on the compressor and vessels.
2. The compressor and vessels will receive a 5-psi helium holding charge.
3. The compressor will not be insulated at the factory. An insulation kit will be shipped with the unit
and will also include a container of adhesive.
4. Only the evaporator shell will be factory insulated. Loose insulation will be shipped for the
remaining surface areas.
5. The starter will ship loose.
6. The refrigerant will be field supplied.
7. All field piping connections will be Victaulic, flanged, O-ring face seal or copper brazing.
8. Bracket and cable kit will be included for all unit-mounted starters and/or cableway for mini-cabs.
9. All free piping ends will be capped.
10. Touch-up paint and stick-on wire ties will be included.
11. A bolted bracket instead of a weld will mount the oil pump.
12. The discharge piping assembly will have a bolted flange connection (instead of welded) at the
condenser. This assembly will ship loose.
13. Piping that remains attached to a component will be supported if it is not rigid.
14. The chiller will not be run-tested at the factory but the compressor, oil pump assembly and heat
exchangers will be tested as sub-assemblies.
15. The control panels are shipped separately but have all sensors wired in, labeled and tied up.
Matching labels will exist at the sensor connection to the unit.
Reassembly Steps
NOTE: Additional instructions may be shown on the assembly drawings.
The Type II arrangement is shipped with the evaporator, condenser, tube sheet support plate, oil cooler
and oil sump bolted together. This provides structural support during transit and also allows several
options for disassembly.
Figure 10, Component Disassembly
In most cases for narrow entry, the condenser will be
separated by unbolting it from the evaporator angle
bracket and from the tube sheet support plate. This
leaves the evaporator and the support plate that has
the mounting foot extended under where the
condenser used to be. Therefore, the evaporator is
usually unbolted from the two support plates, which
can then be easily handled by themselves.
14 Field Installation Procedure IM 1128-1
!
WARNING
Remove compressor and vessel holding charge through the Schrader valve in the block-off plates
before attempting to loosen any fittings on them. Failure to do so can cause severe bodily injury.
1. Disassemble the unit to the e xtent required by the site conditions. Rig the components to their final
location and reassemble them using the fasteners that came with the unit.
2. The compressor and its suction and discha rge piping should be installed on the stack before any other
lines are attached. Mount t he compressor on the stack. Mounting bolts, washers and nuts are shipped
loose. Leave the mounting bolts loose until the suction and discharge lines are in place and aligned.
Install the suction and discharge piping. Before tightening the Victaulic couplings, position the suction
and discharge piping so that the compressor can be aligned to give the best fit-up. When this is
achieved, secure the compressor mounting bolts and proceed with installing the Victaulics using a light
coating of Victaulic lubricant. See Figure 3.
3. Install the liquid line using Figure 11 as a guide. Commonly used arrangements are illustrated. The
bottom two arrangements illustrate lines with electronic valves used on some size units. Due to the
variety of vessel combinations available, variation on specific units will occur.
4. Install the motor cooling line using Figure 5 as a guide.
5. Install the liquid injection line (see Figure 4). Note that any given injection line may be configured
somewhat differently than shown on the drawing.
6. If the oil cool er and oi l sump have been removed on the job site, reinsta ll them using the fasteners tha t
came on the unit. See Figure 12 for piping between the cooler and sump and the cooling water pi ping.
See Figure 8 for the balance of the four oil lines connected to the compressor. There are a variety of
fitting types employed on the oil lines. Reconnect the compression fit tings, bolt on the flanges using
new gaskets/O-rings furnished, and re-sweat the sweat connections.
Due to the wide variety of model arrangements, some or all of the oil piping may be shipped loose.
When possible, the cooler and sump will be shipped mounted to their back plate with as much piping
remaining as possible.
7. Install the four-way solenoid valve assembly on the compressor suction housing.
8. Install the two control panels; the compressor panel is mounted adjacent to the oil sump and the unit
panel is on top of the evaporator. Wire and sensor leads have been disconnected at their terminus and
labeled. They remain connected at the panels and rolled up. Their destinations have matching labels,
which simplifies the installation. Compressor panel sensor labels are prefixed with CS, unit panel labels
with US. Use the following drawings as a guide for installing wiring and sensors:

9. If the unit has been ordered with a starter or VFD as unit mounted, brackets for mounting it and
interconnection cables to the compressor motor will be i ncluded as shi p loose ite ms. Control wiring as
shown in Figure 9 will also be required. If the unit has a free-standing starter, use normal field
procedures for mounting and wiring.
Normal procedure of leak testing, triple evacuation, and charging with refrigerant and lubricant must be
followed prior to the start up procedure.

Type III Reassembly
Description
TYPE III: The uni t ships fully assembled and is field ready to knockdown. Included are the vessel
bolt-on connection brackets, the discharge stack bolt-on flanges at the condenser and the bolt-on oil
pump assembly.
1. The unit is shipped fully charged with refrigerant and lubricant.
2. The unit will be factory insulated and painted.
3. All electrical and sensor wiring will be fastened as usual.
4. The starter will ship per order instructions.
5. Touch up paint and stick on wire ties will be included.
6. This unit will be fully tested at the factory.
7. Labels will be provided with the instructions to mark piping, electrical wiring and sensor wiring.
Reassembly Steps
Type III units offer a variety of disassembly opportunities. In some cases the condenser and tube
support plate are removed to meet narrow entrance requirements. Sometimes the compressor and unit
control panel are removed for low height situations. Other possibilities exist.
Therefore it is difficult to prescribe step-by-step procedures. Various secti ons of this manual can be
used where applicable, bearing in mind that the unit is fully charged with refrigerant and lubricant.

WARNING
It is estimated that fifty percent of retrofit applications require partial or complete disassembly of the
chiller. Daikin McQuay offers two solutions to the disassembly and reassembly effort on WMC
chillers.
WMC chillers are relatively easy to disassembly due to the small compressor size and the absence of a
lubrication system with its attendant components and piping.
TYPE IV Knockdown: The compressor(s), control panel, compressor power panel(s) are removed at
the factory and put on skids. The stripped vessel stack is shipped as a single piece. Discharge and
suction piping, liquid line and t he compressor cooling line(s) are removed and crated. All associated
wiring and piping possible will remain on the vessel stack.
1. Block-offs will cover all openings on the compressor and vessels.
2. The compressor and vessels will receive a 5-psi helium holding charge.
3. The suction line(s) is not insulated at the factory. An insulation kit will be shipped with the unit.
4. The evaporator will be insulated at the factory.
5. Refrigerant will not be shipped with the unit and must be secured locally and furnished and
installed by the installer.
6. All field piping connections will be flanged or copper brazing.
7. All free piping ends will be capped.
8. Touch-up paint will be included.
9. The unit will undergo the rigorous, full McQuay test program at the factory.
10. Contact local McQuay Factory Service for pricing and scheduling of required installation
supervision.
TYPE V Knockdown: The unit ships fully assembled, tested and is ready for field knockdown. This
option allows components to be removed as required at the site. The unit dimension drawing gives
sufficient dimensions to determine what should be removed. Approximate reduction in unit size for
Type IV knockdown is shown below

42 Field Installation Procedure IM 1128-1
Type IV Disassembly-Reassembly
!
WARNING
Disassembly
Type IV Knockdown units are shipped disassembled except for the vessel stack and are shipped less
refrigerant, If the stack size or weight dictates further disassembly, the vessels can be separated by
disconnecting any interconnecting wiring and tubing and then unbolting them. The vessels and compressors
have a helium holding charge that must be released prior to attempting to open any connection.
Reassembly
1. Reassemble the vessel stack, if disassembled, and reconnect any wiring and tubing.
2. Mount the compressor(s) on the stack. Be careful to avoid damaging lines already mounted on the unit.
Mounting bolts, washers and nuts are shipped loose. Leave the mounting bolts loose until the suction and
discharge lines are installed and aligned.
During assembly, bolts holding block off plates (suction connection, for example), are used for reassembly
of the component. See Figure 25 for the location and description of the block offs.
3. Do not remove block offs until ready to install piping. The compressor and vessels have a Schrader valve
on their block off plates to be used for relieving the helium holding charge.
Remove compressor, piping or vessel holding charge through the Schrader valve in the block off plates
before attempting to loosen any fittings on them. Failure to do so can cause severe bodily injury.
4. Install the suction and discharge line(s). See Figure 30. Tighten bolts after the entire line has been
installed and aligned. Insulate the suction line with the insulation and glue provided.
5. Install the liquid line and motor cooling lines. See Figure 31 and Figure 32.
6. Install control panel and compressor power panels by bolting to the horizontal support members.
7. If the unit has single-point power, connect the power leads from the terminal box under the control panel
to each power panel line side connection.
8. Connect any loose wiring.
9. Pressure (leak) test, evacuate, and charge with field supplied R-134a using standard refrigeration practice.
Type V Disassembly-Reassembly
Type V units are designed for a wide range of disassembly and the degree of knockdown varies. Use
instructions and drawings from Type IV Disassembly-Reassembly instructions above. Observe the following
recommendations.
1. The chiller is shipped with the full refrigerant charge that must be pumped down into the condenser or
removed before breaking any refrigerant connection. Before attempting any disassembly, assume the
condenser isolation valves may have leaked and that any component of the chiller may be pressurized with
refrigerant. Exert the proper precautions with this caveat in mind.
2. Check that power has been removed from the unit. Before disconnecting any wire, it is prudent to label its
function and connection point to facilitate reconnection.
3. The refrigerant charge must be removed from the unit if the vessels are to be separated.
4. Some insulation repair and touch-up painting may be required.
5. See Type IV instructions for reassembly of components.

Reassembly Steps
NOTE: Additional instructions may be shown on the assembly drawings.
1. Mount the compressor on the stack. Be careful to avoid damaging lines already mounted on the
unit. Mounting bolts, washers and nuts are shipped loose. Leave the mounting bolts loose until the
suction and discharge lines are installed and aligned.
During assembly, bolts holding block-off plates (motor cooling connection, for example), are used
for reassembly of the component. See Figure 1 or Figure 2 for the location and description of the
block-offs.
2. Do not remove block-offs until ready to install piping. The compressor and vessels have a Schrader
valve on their block-off plates to be used for relieving the helium holding charge.
Remove compressor and vessel holding charge through the Schrader valve in the block-off plates
before attempting to loosen any fittings on them. Failure to do so can cause severe bodily injury.
3. Install the suction and discharge piping (see Figure 3). Before tightening the Victaulic couplings,
position the suction and discharge piping so that the compressor can be aligned to give the best fitup. When this is achieved, secure the compressor mounting bolts and proceed with installing the
Victaulics using a light coating of Victaulic lubrication.
4. Install the liquid injection line The liquid injection line is attached to the condenser and has
shipping straps securing it to the evaporator and condenser. It, and the compressor, each have a
block-off.
5. Install the motor cooling line using the same procedure as the liquid injection line.
6. Install the motor drain line (see Figure 6) using the same procedure as the liquid injection line.
52 Field Installation Procedure IM 1128-1
7. Install compressor wiring. The wire end that has been disconnected, and its attachment point on the
compressor, will each have a label attached (VC for the vane close switch, for example) for
matching purposes.
• Guardistor, G1 (and G2 on some units), terminal box located on side of motor housing.
• Vane load/unload solenoids, SA and SB, located on the four-way solenoid assembly.
• Vane close switch, VC, located on compressor next to the discharge housing.
• Vane open switch, VO, located on suction end of compressor.
• High pressure switch, HPS, located on compressor discharge nozzle.
8. Mount the VFD power panel on the brackets in the front of the unit and interconnect to the
compressor motor using the cables provided. Control wiring will also be required. The field wiring
diagram located on the control panel door should also be consulted.
9. Normal procedure of leak testing, triple evacuation, and charging with refrigerant and lubricant
must be followed prior to the start up procedure.
10. After leak testing, insulate the compressor motor, suction line, and other miscellaneous areas with
the included insulation and adhesive. The following components should be insulated:
Evaporator Evaporator water heads Expansion valve
Motor cooling lines Suction elbow VFD cooling line
Stator cooling line Evaporator tube sheets
This completes the reassembly procedure.
Type II Reassembly
TYPE II ... Type II provides a total knockdown of the unit. The compressor and VFD power panel
are removed and put on a skid. The touchscreen and mounting arm will ship in a separate container.
The condenser, evaporator, and tube sheet supports will remain connected only by the attachment
bolts for easy disassembly at the job site. All wiring and piping that interconnects the components
will be removed. The remaining loose parts will be packaged in a separate crate.
1. Block-offs will cover all openings on the compressor and vessels.
2. The compressor and vessels will receive a 5 psi helium holding charge.
3. A compressor insulation kit will be shipped with the unit.
4. Only the evaporator shell will be factory insulated. Loose insulation and glue will be shipped
for the remaining surface areas.
5. The compressor and VFD power panel will ship loose.
6. Refrigerant will be field supplied and installed.
7. All field-piping connections will be grooved mechanical couplings, O-ring face seal or copper
brazing.
8. Touch-up paint and stick-on wire ties will be included.
9. The discharge piping and suction elbow will be shipped loose in a separate crate.
10. The unit will undergo the rigorous, full Daikin McQuay run-test program at the factory.
11. Contact local McQuay Factory Service for price quotation and scheduling.

WARNING
NOTE: Additional instructions may be shown on the assembly drawings.
The Type II arrangement is shipped with the evaporator, condenser, tube and sheet support plate bolt ed
together. This provides structural support during transit and also allows several options for
disassembly.
Figure 35, Component Disassembly
In most cases for narrow entry, the condenser will be
separated by unbolting it from the evaporator angle
bracket and from the tube sheet support plate. This
leaves the evaporator and the support plate that has
the mounting foot extended under where the
condenser used to be. Therefore, the evaporator is
usually unbolted from the two support plates, which
can then be more easily handled by themselves.
Remove compressor and vessel holding charge through the Schrader valve in the block-off plates
before attempting to loosen any fittings on them. Failure to do so can cause severe bodily injury.
11. Disassemble the unit to the e xtent required by the site conditions. Rig the components to their final
location and reassemble them using the fasteners that came with the unit.
12. The compressor and its suction and discharge piping should be installed on the stack before any other
lines are attached. Mount t he compressor on the stack. Mounting bolts, washers and nuts are shipped
loose. Leave the mounting bolts l oose until the suction and discharge lines are in place and aligned.
Install the suction and discharge piping. Before tightening the grooved mechanical couplings, position
the suction and discharge piping so that the compressor can be aligned to give the best fit-up. When this
is achieved, secure the compressor mounting bolts and proceed with inst alling the grooved mechanical
using a light coating of lubricant. See Figure 3.
13. Install the liquid line using Figure 11 as a guide. Due to the variety of vessel combinations available,
variation on specific units will occur.
14. Install the motor cooling line using Figure 5 as a guide.
15. Install the liquid injection line (see Figure 4). Note that any given injection line may be configured
somewhat differently than shown on the drawing.
16. Install the four-way solenoid valve assembly on the compressor suction housing.
17. Install the control panel; the unit panel is on top of the condenser. Wire and sensor leads have been
disconnected at their terminus and labele d. They remain connected at the panel and rolled up. Their
destinations have matching labels, which simplifies the installation. :

Description
TYPE III: T he unit ships fully assembled and charged and is field ready to knockdown as required
after refrigerant is pumped down or removed. Included are the vessel bolt-on connection brackets and
the discharge stack bolt-on flanges at the condenser.
1. The unit is shipped fully charged with refrigerant.
2. The unit will be factory insulated and painted.
3. All electrical and sensor wiring will be fastened as usual.
4. The VFD will be installed.
5. Touch up paint and stick on wire ties will be included.
6. This unit will be fully tested at the factory.
7. Labels will be provided with the instructions to mark piping, electrical wiring and sensor wiring.
Reassembly Steps
Type III units offer a variety of disassembly opportunities. In some cases the condenser and tube
support plate are removed to meet narrow entrance requirements. The compressor and VFD power
panel may be removed for low height situations. Other possibilities exist.
Therefore it is difficult to prescribe step-by-step procedures. Various secti ons of this manual can be
used where applicable, bearing in mind that the unit is fully charged with refrigerant.
Prior to un-sweating any connection in the field, verify there is no pressure or charge in the
component or lines. Failure to do so can cause severe injury or dearth.
Avoid applying excessive heat to valve seats when brazing or removing lines. Use cooling on valve
components. Failure to do so will cause valve damage.
Cover any opening to prevent foreign objects from entering. Failure to do so can cause equipment
damage.

Compressor Removal and Re-Attachment
Removal Preparation
1. Close the king valve at condenser liquid line outlet.
2. Close all other related shut-off valves.
3. Pump the refrigerant charge down into the condenser.
4. Ensure that the charge has been removed from the compressor and evaporator and that the discharge
check valve is holding the charge in the condenser.
5. Loosen and remove bolts on either side of the compressor discharge nozzle (see Figure 46, flag #1).
Compressor Removal
1. Loosen and remove bolts on either side of the cast suction elbow (see Figure 45, flag #2).
2. Remove rotor cooling return line on the underside of the compressor motor housing along with both
rotor cooling supply lines per Figure 43 noted as "mechanical break points”, and Figure 39,
3. Remove (2) DIN connectors from the solenoid coils (see flag #3 on Figure 41 and Figure 42).
4. Remove rotor stepping valve control wire ( see flag #4 on Figure 43).The wire ties will have to be cut
away during this process.
5. The following wires coming from the VFD will need to be removed (Figure 40):
- 300v dc power supply ( yellow cable )
- 25 pin "D" shell connector
- power leads on the top of the motor housing
- Ethernet cable coming from the unit control box
6. Remove the wireway box assembly from the compressor to the back of the VFD.
7. Loosen the (4) bolts from the compressor's bottom mounting feet see Figure 45, flag #5). Do not
loosen or remove bolts securing the compressor brackets as height is pre-set from the factory.
8. Mount a 1/2-13 swivel lifting eye to the front tapped lif ti ng hole on the compressor motor housing. (see
Figure 45, flag #6). The compressor weight is 1000 lbs.
Compressor Re-Attachment
The following gaskets and “O” rings required for compressor reassembly are shipped loose:
Table 10, WME 500 Type III Knockdown “O” Rings and Gaskets
070194992 1 “O” Ring Between suction nozzle and compressor inlet connection
070199039 1 Gasket
Notes:
1. There are four identical gaskets for the discharge pipe, all are not used.
2. Blank-off plates not shown but may be required for extended aperture opening. The discharge nozzle is the short
section of pipe with fittings between the compressor volute and the discharge pipe.
1. Set the suction elbow back on top of the evaporator and install the screws loosely at the evaporator
flange, being sure to inspect the O-rings for damage and replace if needed.
Between compressor discharge nozzle and upper discharge
2. Set compressor on mounting brackets and install the (4) mounting bolts loosely. Install the gasket at
check valve and insert bolts through the spool piece.

3. Install (12) bolts at elbow to compressor and torque to 25 ft-lbs; do not over-tighten.
4. Install (18) bolts at evaporator flange to the suction line and torque to 62 ft-lbs; do not over-tighten.
5. Torque the (8) bolts to the spool piece at the check valve to 205 ft-lbs.
6. Re-install the wireway between the compressor and the VFD.
7. Re-attach all associated power wiring & Ethernet cable.
8. Evacuate the evaporator and VFD cooling lines to 300 microns for one hour.
9. Open all valves.
10. Perform refrigerant leak check to ensure all connections and fittings are securely fastened.
