other foreign material. Supply and return hoses should be
connected  together  during  this  process  to  ensure  the
entire  system  is  properly  flushed.  After  the  cleaning  and
flushing has taken place the unit may be connected to the
water loop and should have all valves wide open.

EARTH COUPLED SYSTEMS:

Closed  loop  and  pond  applications  require  specialized
design  knowledge.  No  attempt  at  these  installations
should  be  made  unless  the  contractor  has  received
specialized training.

Anti  freeze  solutions  are  utilized  when  low  evaporating
conditions  are  expected  to  occur  (I.E.:  low  loop
temperatures  in  heating).  Typical  temperatures  are  30°F
fluid temperature in heating and 100°F in cooling.

MAINTENANCE:

1)

Filter  changes  or  cleanings  are  required  at  regular
intervals. The time period between filter changes will
depend  upon  type  of  environment  the  equipment  is
used  in.  In  a  single  family  home,  that  is  not  under
construction, changing or cleaning the filter every 60
days  is  sufficient.  In  other  applications,  such  as
motels,  where  daily  vacuuming  procedures  a  large
amount  of  lint,  filter  changes  may  need  to  be    as
frequent as biweekly.

2)

An  annual  “checkup”  is  recommended  by  a  licensed
refrigeration  mechanic.  Recording  the  performance
measurements  of  volts,amps,  and  water  temperature
differences 

(both 

heating 

and 

cooling) 

is

recommended. This  data  should  be  compared  to  the
information  on  the  unit's  data  plate  and  the  data
taken at the original startup of the equipment.

3)

Lubrication of the blower motor is not required.

4)

The condensate drain should be checked annually by
cleaning or flushing to insure proper drainage.

5)

Periodic  lockouts  almost  always  are  caused  by  air  or
water  flow  problems. The  lockout  (shut  down)  of  the
unit  is  a  normal  protective  measure  in  the  design  of
the  equipment.  If  continual  lockouts  occur  call  a
mechanic  immediately  and  have  them  check  for:
water flow problems, water temperature problems, air
flow  problems  or  air  temperature  problems.  Use  of
the pressure and temperature charts for the unit may
be required to properly determine the cause.

SYSTEM CHECKOUT:

After  completing  the  installation,  and  before
energizing  the  unit,  the  following  system  checks
should be made: 

Verify  that  the  supply  voltage  to  the  heat  pump  is  in
accordance with the nameplate ratings.

Make sure that all electrical connections are tight and
secure.

Check the electrical fusing and wiring for the correct
size.

Verify  that  the  low  voltage  wiring  between  the
thermostat and the unit is correct.

Verify that the water piping is complete and correct.

Check  that  the  water  flow  is  correct,  and  adjust  if
necessary.

Check  the  blower  for  free  rotation,  and  that  it  is
secured to the shaft.

Verify that vibration isolation has been provided.

Unit  is  serviceable.  Be  certain  that  all  access  panels
are secured in place.

UNIT START-UP:

1.

Set the thermostat to the highest setting.

2. 

Set  the  thermostat  system  switch  to  "COOL",  and  the
fan switch to the "AUTO" position. The reversing valve
solenoid  should  energize.  The  compressor  and  fan
should not run.

3.

Reduce  the  thermostat  setting  approximately  5
degrees below the room temperature.

4.

Verify  the  heat  pump  is  operating  in  the  cooling
mode.

5.

Turn  the  thermostat  system  switch  to  the  "OFF"
position.  The  unit  should  stop  running  and  the
reversing valve should deenergize.

6.

Leave  the  unit  off  for  approximately  (5)  minutes  to
allow for system equalization.

7.

Turn the thermostat to the lowest setting.

8.

Set the thermostat switch to "HEAT".

9.

Increase  the  thermostat  setting  approximately  5
degrees above the room temperature.

10. Verify  the  heat  pump  is  operating  in  the  heating

mode.

11. Set  the  thermostat  to  maintain  the  desired  space

temperature.

12. Check for vibrations, leaks, etc...

FREEZE SENSOR 

This is optional and can be set to ignore or monitor a freeze
sensor.There are 2 configurable freeze points, 35°F & 15°F.
The  unit  will  enter  a  soft  lock  out  until  the  temperature
climbs  above  the  set  point  and  the  anti-short  cycle  time
delay  has  expired.  The  freeze  sensor  may  not  provide
protection in the case of loss of flow in the heating mode.
A  flow  switch  or  pressure  differential  switch  is
recommended to prevent unit operation in case of loss of
flow.
