nstallation Drawings
Dimension and connection data for this tank can be found on the General
Arrangement drawing supplied with each tank. Additional copies of these
drawings can be purchased from the factory. Please include information
on tank model number, part number, serial number and project number, if
known, in drawing requests.
Rigging Instructions
Vertical tanks are shipped in the horizontal position, secure on permanent
shipping legs (500,900,1,500, and 3,000 gallon) or on temporary wooden
cradles (6,000, 9,000, 11,000 and 13,000 gallon) which must be removed
prior to erection of the tank. Make certain that rigging equipment has
adequate capacity to safety handle the weights involved. Employ experi-
enced personnel for erection of the tank. Re-use the wooden cradles
supplied with the tank if the tank must be stored in the horizontal position.
Caution
To prevent possible tip over, do not leave the tank standing upright unless
it is anchor bolted on its specified foundation or other hard surfaces
capable of supporting its weight. Loading on the tank legs is great enough
to cause them to sink into most surfaces other than reinforced concrete,
and a brisk wind may cause the tank to tip over.
Pre-Installation Inspection
Before erecting the tank, inspect it carefully for possible shipping
damage.Report any damage to the carrier and the factory. In addition,
check thevacuum as follows:
1. These tanks are shipped pressurized with nitrogen gas. Check tank
pressure by connecting a 0-30 psig (0-207 kPa/0-2 bar) pressure
gauge to the outlet tube of the full trycock valve using welding hose
and clamps or using the pressure gauge supplied with the tank. If
pressure is below 3 psig (21 kPa/0.2 bar) and no repairable leaks are
found, contact the factory in accordance with the warranty.
2. Check insulation space vacuum. If “as received” vacuum (tank at
ambient temperature) is above 750 microns, contact the
factory.
