ZHA SERIES
Service Literature 7.5 to 10 ton
26.3 to 35.2 kW
ZHA092 through 120
The ZHA commercial heat pump is available in 7.5, 8.5 and
10 ton capacities. The refrigerant systems utilize two com
pressors, two reversing valves, two accumulators, and
other parts common to a heat pump. Optional auxiliary
electric heat is factory or field installed. Electric heat oper
ates in single or multiple stages depending on the kW input
size. 7.5kW through 60kW heat sections are available.
Units are designed to accept any of several different energy
management thermostat control systems with minimum field
wiring.
Information contained in this manual is intended for use by
qualified service technicians only. All specifications are sub
ject to change. Procedures outlined in this manual are pre
sented as a recommendation only and do not supersede or
replace local or state codes.
If the unit must be lifted for service, rig unit by attaching four
cables to the holes located in the unit base rail (two holes at
each corner). Refer to the installation instructions for the proper
rigging technique.
WARNING
Improper installation, adjustment, alteration, ser
vice or maintenance can cause property damage,
personal injury or loss of life. Installation and ser
vice must be performed by a licensed professional
HVAC installer or equivalent service agency.
CAUTION
Electrostatic discharge can affect electronic
components. Take precautions during unit instal
lation and service to protect the unit's electronic
controls. Precautions will help to avoid control
exposure to electrostatic discharge by putting
the furnace, the control and the technician at the
same electrostatic potential. Neutralize electro
static charge by touching hand and all tools on an
unpainted unit surface, such as the blower deck,
before performing any service procedure.
ELECTROSTATIC DISCHARGE (ESD)
Precautions and Procedures
CAUTION
As with any mechanical equipment, contact with
sharp sheet metal edges can result in personal in
jury. Take care while handling this equipment and
wear gloves and protective clothing.
WARNING
Electric shock hazard. Can cause injury
or death. Before attempting to perform
any service or maintenance, turn the
electrical power to unit OFF at discon
nect switch(es). Unit may have multiple
power supplies.

102 AND 120S STANDARD EFFICIENCY BELT DRIVE BLOWER − BASE UNIT
BLOWER TABLE INCLUDES RESISTANCE FOR BASE UNIT ONLY (NO HEAT SECTION) WITH DRY INDOOR COIL AND AIR
FILTERS IN PLACE. FOR ALL UNITS ADD:
1 − Wet indoor coil air resistance of selected unit.
2 − Any factory installed options air resistance (heat section, economizer, etc.)
3 − Any eld installed accessories air resistance (duct resistance, diffuser, etc.)
Then determine from blower table blower motor output required.
See page 9 for blower motors and drives.
See page 9 for wet coil and option/accessory air resistance data.

NOTE - Using total air volume and system static pressure requirements determine from blower performance tables rpm and motor output required. Maximum usable
output of motors furnished are shown. In Canada, nominal motor output is also maximum usable motor output. If motors of comparable output are used, be sure to keep
within the service factor limitations outlined on the motor nameplate.
NOTE – Units equipped with MSAV® (Multi-Stage Air Volume) option are limited to a motor service factor of 1.0.
