UNIT INSTALLATION
LOCATION
Before starting the installation, select and check the suitability
of the location for both the indoor and outdoor unit. Observe
all limitations and clearance requirements.
The outdoor unit must have sufficient clearance for air
entrance to the condenser coil, for air discharge and for ser-
vice access. See Figure 1.
If the unit is to be installed on a hot sun exposed roof or a
black-topped ground area, the unit should be raised suffi-
ciently above the roof or ground to avoid taking the accumu-
lated layer of hot air into the outdoor unit.
Provide an adequate structural support.
GROUND INSTALLATION
The unit may be installed at ground level on a solid base that
will not shift or settle, causing strain on the refrigerant lines
and possible leaks. Maintain the clearances shown in Figure
1 and install the unit in a level position. Isolate the base from
the structure to avoid noise or vibration transmission.
Isolate the unit from rain gutters to avoid any possible wash
out of the foundation.
Normal operating sound levels may be objectionable if the
unit is placed directly under windows of certain rooms (bed-
rooms, study, etc.).
Condensate will drain from beneath the coil of the outdoor
unit during the defrost cycle. Normally this condensate may
be allowed to drain directly on the ground.
Elevate the unit sufficiently to prevent any blockage of the air
entrances by snow in areas where there will be snow accu-
mulation. Check the local weather bureau for the expected
snow accumulation in your area.
ROOF INSTALLATION
When installing units on a roof, the structure must be capable
of supporting the total weight of the unit, including a pad, lin-
tels, rails, etc., which should be used to minimize the trans-
mission of sound or vibration into the conditioned space.
UNIT PLACEMENT
1. Provide a base in the pre-determined location.

2. Remove the shipping carton and inspect for possible
damage.
3. Compressor tie-down bolts should remain tightened.
4. Position the unit on the base provided.
5. Sit unit on the (4) rubber elevating grommets provided
with the unit. These should be positioned as shown in
Figure 2 to reduce noise and allow for proper drainage.
6. Make a hole(s) in the structure wall large enough to
accommodate the insulated vapor line, the liquid line and
the wiring.
DISCHARGE LINE FILTER-DRIER
The E*FD 018 - 042 heat pumps have a solid core filter-drier
located in the discharge line. Due to its location in the refrig-
erant circuit it requires a unique oversize capacity drier. E*FD
048 and 060 have a solid core bi-flow filter/dryer on the liquid
line.
NOTE: Replacement of the discharge line drier must be the
exact same as marked on the original factory drier. See
Source 1 for O.E.M. replacement driers.
PIPING CONNECTIONS
The outdoor condensing unit may be connected to the indoor
evaporator coil using field supplied refrigerant grade copper
tubing that is internally clean and dry. Units should be
installed only with the tubing sizes for approved system com-
binations as specified in Tabular Data Sheet. The charge
given is applicable for total tubing lengths up to 15 feet. See
Application Data Form 690.01-AD1V for installing tubing of
longer lengths and elevation differences.
NOTE: Using a larger than specified line size could result in oil
returnproblems.Usingtoosmallalinewillresultinloss
of capacity and other problems caused by insufficient
refrigerant flow. Slope horizontal vapor lines at least 1"
every20feettowardtheoutdoorunittofacilitateproper
oil return.
PRECAUTIONS DURING LINE INSTALLATION
1. Install the lines with as few bends as possible. Care must
be taken not to damage the couplings or kink the tubing.
Use clean hard drawn copper tubing where no apprecia-
ble amount of bending around obstruction is necessary.
If soft copper must be used, care must be taken to avoid
sharp bends which may cause a restriction.
2. The lines should be installed so that they will not obstruct
service access to the coil, air handling system or filter.
3. Care must also be taken to isolate the refrigerant lines to
minimize noise transmission from the equipment to the
structure.
4. The vapor line must be insulated with a minimum of 1/2"
foam rubber insulation (Arm-A-Flex or equivalent). Liquid
lines that will be exposed to direct sunlight and/or high
temperatures must also be insulated.
Tape and suspend the refrigerant lines as shown. DO NOT
allow metal-to metal contact. See Figure 3.

5. Total line lengths are limited to 75 feet due to the storage
capacity of the accumulator. Systems with total line
lengths over 50 feet must be provided with a low voltage
start kit. Elevation differences are limited to:
Indoor Above Outdoor 50 ft.
Outdoor Above Indoor 50 ft.
6. Use PVC piping as a conduit for all underground installa-
tions as shown in Figure 4. Buried lines should be kept
as short as possible to minimize the build up of liquid
refrigerant in the vapor line during long periods of shut-
down.
7. Pack fiber glass insulation and a sealing material such
as permagum around refrigerant lines where they pen-
etrate a wall to reduce vibration and to retain some
flexibility.
8. See Form 690.01-AD1V for additional piping information.
PRECAUTIONS DURING BRAZING OF LINES
All outdoor unit and evaporator coil connections are copper-
to-copper and should be brazed with a phosphorous-copper
alloy material such as Silfos-5 or equivalent. DO NOT use
soft solder.
The outdoor units have re-usable service valves on both the
liquid and vapor connections. The total system refrigerant
charge is retained within the outdoor unit during shipping and
installation. The re-usable service valves are provided to
evacuate and charge per this instruction.
Serious service problems can be avoided by taking adequate
precautions to assure an internally clean and dry system.
PRECAUTIONS DURING BRAZING ANGLE VALVE
Precautions should be taken to prevent heat damage to
angle valve by wrapping a wet rag around it as shown in Fig-
ure 5. Also, protect all painted surfaces and insulation during
brazing. After brazing - cool joint with wet rag.
Valve can be opened by removing the plunger cap and fully
inserting a hex wrench into the stem and backing out counter-
clockwise until valve stem just touches retaining ring.
Replace plunger cap finger tight, then tighten an additional 1/
12 turn (1/2 hex flat). Cap must be replaced to prevent leaks.
Connect the refrigerant lines using the following procedure:
1. Remove the cap and Schrader core from both the liquid
and vapor angle valve service ports at the outdoor unit.
Connect low pressure nitrogen to the liquid line service
port.

Dry nitrogen should always be supplied through the
tubing while it is being brazed, because thetempera-
ture required is high enoughto cause oxidationof the
copper unless an inert atmosphere is provided. The
flow of dry nitrogen should continue until the joint has
cooled. Always use a pressure regulator and safety
valve to insure that only low pressure dry nitrogen is
introduced into the tubing. Only a small flow is neces-
sary to displace air and prevent oxidation.
This is not a backseating valve. The service access
port has a valve core. Opening or closing valve does
not close service access port.
Ifthevalvestemisbackedoutpasttheretainingring,
the O-ring can be damaged causing leakage or sys-
tem pressure could force the valve stem out of the
valve body possibly causing personal injury. In the
event the retaining ring is missing, do not attempt to
open the valve.
