to obtain values of Suction/Discharge pressures and

Superheat/Subcooling.

Note the Superheat value before disconnecting the

system. All EMI systems are designed to operate at

optimum capacity and efficiency when running 10° F

Superheat (+/- 2° F) at ARI rating condition of 80/67°

F indoors and 95° F outdoors. Since most startups are

not done at these exact conditions, it is critical to follow

the superheat chart values for given outdoor conditions

when fine tuning the system charge. The other values

should be close under most conditions.

REMOTE THERMOSTAT PLACEMENT

EMI systems can be installed with remote mounted

(wall) thermostat control (24v Class-II low voltage circuit).

Use a thermostat that will provide a signal to the “G” termi-

nal.

NOTE:

 A signal must be present at the  “G”

terminal to operate the evaporator fan in heat

mode.

The thermostat should be mounted 60 inches from the

floor on a “warm” (i.e., INSIDE) or post away from doors,

drafts, or high traffic areas.

FIELD INSTALLED KITS

EMI provides certain kits to modify your existing unit.

We have kits available for widespread use in EMI systems,

including:

• Low Ambient Kits (cooling only- ALWAYS field in-

stalled)

• Hard Start Kits (ALWAYS field installed)

• Condensate Pump Kits (field installed for certain

evaporator models)

• Specific Control Changeover Kits (i.e., “Unit Mount

to Remote T-stat”) for some older model EMI evapo-

rators.

Consult  factory  technical  service  representative  to

choose the exact kit that you will need for your EMI model

unit. Kits change periodically so a kit that worked in one

model year may not work for a unit manufactured in a dif-

ferent model year.

NOTE:

  EMI  does  not  stock  or  recommend

electric heat add-on kits for field installation.

It is critical that, if you can foresee the need

for electric heat in your EMI evaporator, you

initially order it as a factory installed option.

 Adding an electric heater in the field has proved to be

complicated and difficult due to space constraints and/or

the unit being mounted into position already.

EMI will not accept responsibility for the rework per-

formed. EMI’s safety approval listing (ETL) becomes void

at the time a field rework that involves an electric heater

takes place since several items, including breaker size, wire

size, and unit rating are immediately effected.

SYSTEM DATA

If, after routine inspection and adjustments, the sys-

tem is not performing up to standards, call EMI Customer

Service for assistance.  It is important that the “System Data

Form” (see following page) be completely filled out and, if

possible, FAXED to our service group at 1-800-232-9364.

With this information in hand, we can prepare to help you

and handle the situation in a timely and effective manner.

Complete parts listings are available from your dis-

tributor or from the EMI factory. All parts orders must be

entered with the distributor who supplied the original equip-

ment order. If assistance is needed for identifying a part num-

ber or description, please call EMI Customer Service.

When calling EMI for service assistance and/or parts

orders, you will need to provide the complete unit model

number and serial number as obtained from the rating plate

attached to the equipment.

For your convenience, this space is provided to record

the necessary information specified above. Please complete
