WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury. Disconnect all electric
power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes.
The following steps were sequenced to aid in the
installation and mating of a water side economizer to a
water-source heat pump (GEH .5 to 5 ton) and (EXH 1.5 to
6 ton).
1. Remove the control side service panel of the water-
source heat pump unit.
2. Remove rubber isolation grommets from the return-air
section. Place them in a convenient location.
3. Attach ducted panel to the water-source heat pump
unit with six factory provided screws.This panel is
shipped loose with the water-source heat pump but
must be field installed to the unit.
