COMMON TO All AIR HANdlERS - SEqUENCE OF OpERATION

 

Continued

dRY MOdE OpERATION

 

Dry  mode  will  remove  humidity  from  the  air  while 

maintaining a specific setpoint temperature. This is done 

in cooling along with the electric or hydronic heater. Dry mode 

will not

 maintain a specific humidity level. The unit must be 

equipped with an optional electric heat element or hydronic 

coil.

 

For Dry Mode operation first turn the unit on via the 

On/

off

  button. Select 

Dry 

mode via the 

Mode

 button. The room 

temperature will be displayed. Then by depressing either the 

Up

 or 

Down

 arrow once, the setpoint temperature will appear. 

The setpoint temperature can then be changed with each 

successive press of the 

Up

 or 

Down

 arrow or by holding the 

button in.

 

Place the setpoint temperature at a desired room tem-

perature. Depending on the difference between room tem-

perature and set point temperature cooling and/or heating will 

energize. If the room temperature and setpoint temperature 

are the same the unit will operate in cooling and the electric 

heat source will also energize.

 

Should the room temperature fall below the setpoint 

temperature by two degrees, cooling will stop and heating will 

continue to boost the room temperature back up to stepoint 

temperature. If the room temperature rises above the setpoint 

temperature by two degrees, heating will stop and cooling will 

continue to bring the room temperature back down to stepoint 

temperature. The fan will operate continuously at low speed 

while in Dry Mode.

Important:

 The dip switch 1& 2 must be set to ON

 

For electric heat operation first turn the unit on via the 

On/Off

  button. Select 

heat 

mode via the 

Mode

 button. The 

room temperature will be displayed. Then by depressing 

either the 

Up

 or 

Down

 arrow once, the setpoint temperature 

will appear. The setpoint temperature can then be changed 

with each successive press of the 

Up

 or 

Down

 arrow or 

by holding the button in. Place the setpoint temperature 

above room temperature. The electric heat will energize 

and heating will continue as long as the setpoint remains 

above room temperature. Once the room temperature is 

satisfied the electric heat will cycle off. The fan will operate 

as described in “Fan Operation”

UNITS WITH CONdENSATE pUMpS

   EMI Air handlers are available with an optional con-

densate  pump.  Condensate  pumps  are  recommended 

when  it  is  not  possible  to  gravity  drain  the  condensate 

from the indoor unit. Depending on the pump manufacture 

the maximum lift for the pump will vary. Consult the pump 

instructions  for  the  maximum  lift  for  the  particular  pump 

being used or refer to specific pump kit information and 

instructions as supplied by EMI. 

   Condensate generated by the evaporator will collect in 

the pumps’ reservoir. When the water level is high enough, 

a float switch will close and energize the pump motor clear

-

ing the water from the reservoir. Should for any reason the 

water exceed the maximum preset level, a safety switch 

will open. This will prevent the evaporator from generating 

more condensate and spilling out of the unit.
