of your home. Heat is supplied at a lower  
temperature over a longer period of time  
to provide a more constant heat, and it  
may give you the impression that your  
system “never stops running".  
CLEARANCES  
SERVICE CALLS  
The minimum clearances shown below  
must be maintained should any patio or  
yard improvements be done around the  
outdoor unit.  
There are a few instances where you  
can avoid unnecessary service calls.  
(See Troubleshooting Guide above).  
For E*FB systems use the guide but  
disregard the Fault Code column. The  
flashing light on the system thermostat  
of E*FH units is capable of providing you  
with time and money saving information.  
The Fault code numbers listed can be  
handled by taking the corrective action  
indicated. Call qualified serviceman if  
displaying fault code numbers not  
listed.

During the heating cycle, in mild weather  
you may notice water running off the  
outdoor coil. Moisture from the air is  
condensed on the outside surface of the  
coil where it gathers and runs off.

rupt electrical power supply to your

2. Leave on Emergency Heat for at

CHARACTERISTICS  
OF HEAT PUMPS  
3. Switch thermostat back to Heating or  
Auto.  
In order to maintain heating efficiency,  
the system will automatically defrost it-  
self. Steam rising from the outdoor unit  
is normal and is an indication of proper  
operation. The vapor cloud will only last  
for a few minutes. When the defrost  
cycle is completed, the system will auto-  
matically switch back to heating. Electric  
heat is automatically energized to main-  
tain comfort during defrost.  
A CONSTANT HEAT  
COOLING SEASON  
Heat pumps have a noticeably cooler  
supply air temperature than furnaces.  
The common practice of over-sizing fur-  
naces contributes to an “off-and-on-  
again” operation with short blasts of hot  
supply air. The heat pump system is  
1. Switch thermostat to Off position.  
2. Do not switch to Cooling or Auto until  
electrical power has been reestablished  
for 8 hours if the power was off more  
than 8 hours.
