Edwards IH Instruction Manual - Ideal Vacuum Products

Use the following procedure to connect the iH system to your exhaust-extraction system:
refer to Figure 1-1.
1. If the check valve (18) is not required on your application:
• remove the exhaust enclosure (26) by removingthe screws connectingto the rear
bulkhead cover and exhaust enclosure top plate.
• undo and remove the clamp and ‘O’ ring(22 and 21) which secures the check valve to the
elbow (20).
• retain the check valve for possible future use.
2. If neither the check valve (18) nor elbow (20) is required on your application, or if the elbow is
required in a different orientation:
• remove the exhaust enclosure (26) by removingthe screws connectingto the rear
bulkhead cover and exhaust enclosure top plate.
• remove the clamps insulation jacket (24) and retain.
• undo, or remove, the clamped ‘O’ ring that secures the elbow to the exhaust pipe (19).
• reposition, or remove, the elbow (retain both elbow and check valve for possible future
use if removed).
3. Remove the temporary cover or blankingplate from the exhaust outlet. Retain blanking
plate for future use. Retain temporary cover for future use on non-contaminated pumps
only. Use the NW40 trapped 'O' ringand clamp supplied to connect the exhaust outlet on the
check valve (18), or elbow (20), or exhaust pipe (19), to your exhaust extraction system.
4. If the check valve was removed or elbow was removed or reorientated:
• refit the clamps insulation jacket (if removed) on the NW40 joint to your exhaust
extraction system. Use Figure 6-3 as a guide.
• refit the exhaust enclosure (if possible) usingthe screws connectingto the rear bulkhead
cover and exhaust enclosure top plate.
3.11 Connect to your factory extraction system (optional)
As supplied, the temperature control system fitted is sufficient to maintain the iH system at
the correct operating temperature; you do not need to connect an air-extraction system to the
iH system. However, if required you can connect your factory extraction system to the
air-extraction port on the top of the main enclosure (see Figure 2-1).
Note:
The iH system is supplied with a finger guard punched into the top enclosure.
