Master MWC-E Series Installation And Operation Manual page 14

All MWC-SERIES UV Systems must be grounded! The green 14# copper wire coming
out of the power supply must be grounded to the UV Vessel! Attach the copper wire to
the grounding lug to the upper mounting bracket and tighten the screw.
CAUTION:
NEVER LOOK DIRECTLY AT THE ULTRAVIOLET LIGHT WITH THE NAKED EYE. View through a piece of
ordinary glass or optical glasses. ULTRAVIOLET LIGHT may cause eye irritation if eye is not properly protected.
You should never have to look directly at the ULTRAVIOLET LIGHT when installing or
troubleshooting one of our MWC-E Water Sterilizers.
Pre-Treatment:
A complete water test is recommended to determine if pre-treatment equipment is required before installation of
the UV unit. Water must meet criteria below:
Untreated Water Quality
Chloride
Color
Hardness
Iron
Manganese
pH
Total Dissolved Solids
Turbidity
If untreated water quality exceeds the maximum allowable levels specified, this will result in bacteria
passing through the UV unit and into the piping system.
Unit Location:
The MWC-E unit must be installed after the well tank and any
1.
water pre-treatment equipment (softeners, filter, etc.). You must
install a Cartridge type Dirt Filter before the MWC-E unit to
eliminate the possibility of a dirt build-up inside the stainless
steel sterilization chamber. (SEE PAGE 2, PIPING LAYOUT)
2. Install at least 4 feet from a dedicated electrical outlet.
DO NOT INSTALL NEAR ANY HEATING SYSTEMS WHICH
RAISE THE AIR TEMPERATURE OVER 100 DEGREES.
