NOTES:

1.Mount the water source heat pump controller in the equipment controls enclosure with at least two #6 x 1 in. self-tapping screws. Allow adequate clearance for wiring.

2.Verify sensor power and wiring requirements prior to making any terminations. Sen- sors requiring a separate isolated 24 vac power source will not utilize WSHP termi- nals J4-1, or 4.
