How To Replace The Heater
Instructions to replace an MC-MP pack heater in the
vertical/side
position.
5• Remove the last remaining nut
retaining the heater and disengage
heater from spa pack.
6• Replace the defective heater with
a new one, and repeat the same
procedure in reverse order to
reconnect replacement heater
to the spa pack.
4• Use a wrench to remove the ground
cable nut and disconnect the ground
cable wire.
3• Use 1/4" wrench to hold steady and
3/8" wrench to loosen nuts to discon-
nect 2 heater wire connections. Be
careful not to damage ceramic by
twisting or bending.
A few helpful hints when reconnecting:
a) Don't turn wing-nut too tightly, just
enough to hold high temperature
sensor in place.
b) When reconnecting wires from
heater to board, it is important to
use two wrenches to hold nuts
steady. Any bending or twisting
may cause damage to ceramic.
Note: We recommend the use of an
adjustable torque wrench (17 lb/in) to
screw the top nut sufficiently. For more
