Initial Assembly
INTRODUCTION
Your Explorer is assembled and tested at the factory. Some components
are then removed to package the unit. When you receive your Explorer, the
following components will need to be put together.
GENERAL NOTES ON ASSEMBLY
1. All O-rings should be lightly lubricated.
2. Inspect all O-rings for cracks and other damage during each assembly.
3. All breathing loop parts should be sanitized before diving. If assembling
for a dive, see the following section "Complete Disassembly and Reassembly" for further instructions.
Step 1. Remove all parts from the split top box (Fig. 2.1).
Step 2. Open the Oxygen sensor and CO2 sensor (optional) boxes. Remove the sensors from their boxes, and open up the airtight bags.
