In-line Power Supply
The in-line version (current) MegaChlor power supply is a high output indoor power supply and the location
must meet the following requirements.
1. 110 or 220 VAC
2. Water protective cover if not indoors or in a protected area. The power cord should be plugged into a
GFCI protected outlet near the spa. The power cord is 9 feet long and needs to reach the location where
the power supply will be located.
3. The power cable should have a routing path to the power supply where the cable is protected from people
tripping on it and lawn mowers.
4. NOT IN DIRECT SUNLIGHT. The power supply will heat up during operation and if in sunlight it may
overheat.
5. The best location for the power supply is behind the spa's skirt. This will protect the power supply from the
elements. If the power supply is located outside it should be located inside a water proof box and not on
the ground.
6. The 12 Vdc cable from the power supply is 2 ½ feet long and connects into the MegaChlor box. The
power supply must be located near the box or an extension cable will need to be added. If located behind
the spa's skirt a hole will be needed below the control box to route the cable to the box.
7. Once the 12 Vdc cable is routed to the box, remove the cover from the box and route the cable into the
box through the open cable grip. The red wire goes to the Vdc In Red terminal and the black (or bare) wire
goes to the Black Gnd terminal. A small standard screwdriver will be needed to tighten the connection.
Make sure the ferrule is inserted properly, sometimes it slips below the post and doesn't make a
connection. If the red and black wire are reversed damage to the circuit may occur if it is turned on.
MegaChlor Cell Installation
The MegaChlor cell will hang over the edge of the pool or spa and hang
down into the water. Find a location where the cell will be at least 1" from
the side of the pool or spa and for best results as deep as possible. The
deeper the cell is the more time the chlorine has to dissolve into the
water before reaching the surface. Placing by a jet is also desirable as
that will help to mix the chlorine.
If the cable is routed on the pool deck put a protective mat over it to
reduce tripping hazards.
Pool Cleaners: Make sure the cell is in a location where the pool cleaner
will not get tangled in the cable.
