3.2 Installation
Sentry/ST Systems are designed to operate in a controlled environment,
which is free from extreme temperatures, high humidity and/or excessive
amounts of airborne particulates, such as dust and smoke.
3.2.1 Mattress Replacement:
1. Remove the current mattress from the bed frame.
2. Unroll the Sentry/ST Mattress Replacement on the frame.
3. Position mattress and hoses so that the:
 CPR hose assembly is to the LEFT of the controller
 LAL hose is to the LEFT of the controller
4. There are two sets of straps with D-rings on each side of the
mattress and one at the head of the mattress. Use these straps
to secure the mattress replacement to the bed frame.
Caution! Verify that the attachment of the mattress does
not interfere with the bed movement or operation. This could
result in damage to the mattress.
