3.1 Enclosure Installation
Tools Needed:
• Ratchet set with 6” extension
• Vapor Barrier
• Utility Knife
Procedure:
A 25-year continuous vapor barrier must be used between the enclosure and pad to prevent moisture ingress and
possible corrosion caused by metal to concrete contact. The vapor barrier material (such as 30 lb. felt, neoprene pond
liner, or heavy grade tar paper) should initially extend at least six inches in all directions around the perimeter of the
enclosure.
1. Unwrap the enclosure and inspect the contents. If items are missing or damaged, contact Alpha Technologies and
the shipper immediately.
2. Place the vapor barrier material on the pad.
3. Unbolt the enclosure from the shipping pallet.
4. Using an appropriate lifting device, lift the enclosure off the shipping pallet and place over the mounting studs on
the pad.
5. Secure the enclosure to the pad using four (two front, two rear) stainless steel flat washers, lock washers, and
nuts.
6. Trim the vapor barrier material with an appropriate cutting tool.
