Union Gard 160 Installation Methods:
Pour Method
UnionGARD 160 can be gravity poured into a relatively dry drill hole. However, when more than five feet of water is standing in the drill hole the water should be removed before installing the UnionGARD160. If it is not possible to remove the water first, then the product should be pumped to the bottom of the drill hole. UnionGARD 160 will displace the water from the drill hole into the elevator pit floor where it can be removed by bailing or pumping. We recommend the pump method of installation.
Pump Method
Obtain the Union Gard electrical vertical drum pump from www.uniongard.com. You will need a 1" ID non-collapsing rubber hose, or PVC piping, to extended from the discharge side of the pump to the bottom of the drill hole. Connect the pump to the two inch bung cap on the drum. (Do not prime the pump). If necessary, use a 1" PVC pipe as a dip tube and pump the Union-Gard 160 to the bottom of the hydraulic cylinder hole. Doing this will force any water, oil or other debris to the top of the annulus. Once you have completely filled the casing with UnionGARD 160 you can rinse the pump with water or mineral oil for future use.
Notes:
1) If the pump shuts down during the fill, check the line for kinks, and restart when the motor cools. There is an automatic overheat protection on the motor.
2) The pump will not be damaged if operated dry, however it is not recommended to operate under dry conditions for extended periods of time.
3) Ensure UnionGARD 160 is 50 degrees F before pumping.
4) Pump UnionGARD 160 until the product appears at the pit floor. (We suggest cleaning any spills with a citrus-based cleaner such as D-Limonene.)
Sealing The Annulus
Back fill on the outside of the casing, (PVC, etc) with sand. The sand will provide a vertical column on the outside of the casing. This helps prevent vertical stretching of the PVC piping. It is recommended that the annulus be sealed by using a quick setting hydraulic cement. An orifice should be installed for inspection purposes.
