PRECAUTIONS

Carefully read and follow instructions.

WARNING: Risk of electrical shock. If your water pipes are used to ground your home’s electrical system, install a No. 8 AWG jumper wire (or larger) around the filter. The jumper wire must be connected at both ends by a pressure wire fitting or other connection that satisfies NEC or CEC and local codes. Consult a building inspector or licensed electrician for more information.

WARNING: Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

Filter must be protected against freezing, which can cause cracking of the filter and water leakage.
The rubber O-ring provides the water-tight seal between the cap and the bottom of the housing. It is important that the O-ring be properly seated in the groove above the threads of the housing or a water leak could occur.
Because of the product’s limited service life and to prevent costly repairs or possible water damage, we strongly recommend that the bottom of all plastic housings be replaced every five years for clear and every ten years for opaque. If the bottom of your housing has been in use for longer than this period, it should be replaced immediately. Date the bottom of any new or replacement housing to indicate the next recommended replacement date.
Do not use electrical heating tape on this unit.
