Bonding; Bonding And Plumbing Step-By-Step Instructions - Hayward Above-Ground Heat Pump Owner's Manual

Bonding

!
CAUTION
Because all metals have different electrical potentials, all metal and electrical
components of the pool system must be bonded together. This includes the
metal framework of the pool, the light, the pump, the fi lter (if made out of metal),
the heater, any automatic chlorine generator, and any other metal or electrical
equipment. On some older pools, this substructure bond wire may not exist.
In these cases, a 6 to 8 foot solid copper rod must be driven into the ground
near the equipment. All electric and metal components must then be bonded
to each other, and then to the copper rod.
Bonding and Plumbing
step-by-step instructions
1. A 1/3 lb check valve must be installed between
the heater and any automatic chlorine distribution
system (if used).
2. Any kind of automatic chlorine distribution system
must be installed after or downstream of the heat
pump.
3. The fi lter must be placed before or upstream from
the heat pump.
4. A bypass and shut-off should be installed on
all systems for ease of service, maintenance and to
balance the water fl ow. Bypasses must be installed
on any system with over a 3/4 HP pool pump.
