Installation Steps
Stand Mounted Units Only
VMS® Wall Mounted Units Only
Note: Mounting hardware not included for wall installation.
Step 1: Prepare Base
Remove contents from cartons. Place base with casters on floor.
Wood Stud Mounting
Use #12 x 2 1/2" wood screw and #12 x 5/8" flat washer to mount wall bracket to wood stud thru 1/2" min dry wall.
Note: Two screws are required for each mounting.
Concrete Wall Mounting
A) Drill hole in wall for #12 lead anchor as instructed by anchor manufacturer.
B) Drive anchor in wall.
C) Use #12 x 2" screw and #12 x 5/8" flat washer to screw wall bracket into anchor.
Note: Repeat for each mounting hole.
Diagrams illustrate wood stud and concrete wall mounting methods for the wall bracket. The mounting surface is shown with measurements of 6.300 inches (16 cm). The concrete wall mounting shows the use of a lead anchor. Identifiers VA1139, VA114401 are present.
Note: Refer to chase installation manual for mounting hole locations. To install VMS, use hardware included with chase cabinet. (5/16" bolts, washers and nuts)
Step 2: Install Mounting Column
Install tapered end of mounting column into base.
Diagrams show the base with casters, the column, and the chase/wall bracket components. Identifiers VA17711, VA1770i are present.
Assembly Steps
Step 3: Install Absorber/Drawer/Shelf Assembly
Install absorber/drawer/shelf assembly into column/stud.
VMS® Stand Mounted
Diagram shows the VMS stand-mounted unit assembly. A 'Post Spacer' is shown, and the assembly is secured by tightening a 'T-handle'. Identifier VA114001 is present.
VMS Plus™ & VMC™
Diagrams illustrate the assembly for VMS Plus™ and VMC™ models. Components include the main unit, a shelf, and mounting hardware. Identifier VA1141 is present.
VMS Wall Mounted
Diagram shows the VMS wall-mounted unit assembly. Dimensions are provided: 8.37" (21.26 cm) To Wall, 6 3/4" (17.15 cm) Swing Radius, 8" (20.32 cm) width. A 'Post Spacer' is shown with a size of 2 3/4" (6.99 cm). It also notes a 65° (Degrees) range in both directions and a 3" (7.62 cm) dimension. A note specifies using a 3/4" (1.9 cm) Post Spacer with VMS and Monitor Wall Mount Combination instead of the 2 3/4" (6.99 cm) one used with the VMS wall mount. Identifier VA1633 is present.
Assembly Steps
Step 4: Install Vaporizer
Note: Vaporizer is not included with anesthesia machine, however the mounting kit and 10 mm nut driver for vaporizer installation is included.
VMS® Stand and Wall Mounted Units
Diagrams show the mounting of a vaporizer onto VMS stand and wall-mounted units. The vaporizer is labeled 'VIP Use Only Isoflurane'. The process involves attaching a bracket and securing it with fasteners. Identifier VA114601 is present.
VMS Plus™ and VMC™
Diagrams show the mounting of a vaporizer onto VMS Plus™ and VMC™ units. The VMC™ diagram shows the vaporizer mounted on a shelf unit.
CAUTION - VMS Plus™ Model ONLY
For proper machine balance, mount single vaporizer as shown. Mount second vaporizer at other end.
Assembly Steps
Step 5: Install Tubing, Breathing Bag, and Breathing Circuit
Install tubing, breathing bag and breathing circuit.
Main Diagram
The diagram illustrates the connection of tubing and the breathing circuit. Components shown are 'Vaporizer Inlet', 'Breathing Circuit', 'Breathing Bag', 'Vaporizer Outlet', and a '"Y" Connector'. The 'Breathing Circuit' connects to the machine, and the 'Breathing Bag' connects to the circuit. The 'Vaporizer Outlet' connects to the 'Y' Connector, which then connects to the 'Fresh Gas Connection' on the machine.
REFERENCES
Diagrams for VMC™ and VMS Plus™ show how the connections are made on those specific models. The VMC™ reference shows the connection to the 'Fresh Gas Connection'. The VMS Plus™ reference shows the overall setup.
Assembly Steps
Step 6: Install Absorber Canister
Unlock canister latches. Remove canister from side of assembly. Fill with absorbent according to specifications on canister label. Reinstall canister and secure latches.
Diagram shows the anesthesia machine's absorber canister area. 'Canister Latches' are highlighted. A separate view shows the 'Canister' itself. The canister has a label indicating 'For Veterinary Use Only' and 'Use Only Isoflurane'. Identifier VA1162 is present.
Leak Test Procedure
Step 7: Connect Oxygen Tank and Perform Leak Test
Equipment Alert: Do not activate the oxygen flush during any part of this leak test.
To perform leak test...
- Close APL (Scavenging /Adjustable Pressure Limiting) valve by turning knob clockwise.
- Place thumb over patient connection of breathing circuit Y.
- Remove breathing bag and cover bag port opening. (Use palm of hand that is covering Y.)
- With oxygen (50-55 PSI [3.4-3.8 Bar]) supplied to anesthesia machine, slowly open flowmeter to register 30cm H2O on anesthesia machine pressure gauge.
- Turn off flowmeter when pressure reaches 30cm H2O. (If pressure holds steady the system is leak free but if pressure drops, proceed to step (F).)
- Slowly open flowmeter until pressure stabilizes at 30cm. H2O setting. (This determines the magnitude of the leak. If leak rate is greater than 300ml/min; proceed to step (G).)
- Refer to "What if machine leaks?".
- Replace reservoir bag. Repeat step (B) and steps (D) through (F). This will determine the integrity of breathing bag.
- Open APL Valve at end of Leak Test Procedure by turning knob counter clockwise.
Diagram shows the anesthesia machine's front panel components relevant to the leak test: APL Valve (Scavenging /Adjustable Pressure Limiting), Pressure Gauge, Occlusion Valve (VMS® only), and Flowmeter. Identifier VA113301 is present.
What if Machine Leaks?
- Breathing Bag: If leak occurs, replace.
- Breathing Circuit: Install new breathing circuit or obstruct inhalation / exhalation openings to determine if leak originates from breathing circuit.
- Vaporizer Fittings: Verify fittings and tubing are securely attached.
- Canister Gaskets: Check for loose absorbent grains between canister housing gaskets.
- Canister: Verify Canister is seated properly.
- Safety Valves: Remove valve and obstruct opening to determine if leak originates from negative pressure relief valve. Check the o-ring under valve for damage.
- APL Valve: Remove valve and obstruct opening to determine if leak originates from APL valve. Check the o-ring under valve for damage.
- Occlusion Valve: Remove valve and obstruct opening to determine if leak originates from Occlusion valve. Check the o-ring, diaphragm and back up ring on valve for damage.
- O-Rings: Check O-Rings under chrome retaining rings for damage.
