INSTALLING DRIP PIPING
Poorly or improperly installed drip pipes can seriously interfere with the operation of these merchandisers, and result in costly maintenance and product losses. Please follow the recommen- dations listed below when installing drip pipes to ensure proper installation.
1.Never use drip piping smaller than the nominal diameter of the pipe or water seal supplied with the merchandiser.
2.When connecting drip piping, the water seal must be used as part of the drip piping to prevent air leakage or insect entrance. Never use two water seals in series in any one drip pipe. Double water seals in series will cause an air lock and prevent draining.
3.Pitch the drip piping in the direction of flow. There should be a minimum pitch of 1/8 in. per foot (3 mm per 300 mm).
4.Avoid long runs of drip piping. Long runs make it impossible to provide the pitch necessary for good drainage.
5. Provide a suitable air break between flood rim of the floor drain and outlet of drip pipe. To meet code on low base merchandisers, it may be necessary to install a
6.Prevent drip pipes from freezing:
A.Do NOT install drip pipes in contact with uninsulated suction lines. Suction lines should be insulated with a
B.Where drip pipes are located in dead air spaces, such as between merchandisers or between a merchandiser and a store wall, provide means to prevent freezing.
Note: To prevent condensation problems, the water seal should be insulated.
