C. Wire Thermostat Cable to Unit Terminal Strip
Attach thermostat wires to low-voltage terminal block on left side of
control box in locations indicated in Figure 12.
Figure 17 — Terminal and Switch Location
NOTE: Do not connect any unused thermostat cable wires.
CAUTION: Recheck wiring color code schedule to be certain proper
terminals are connected before applying power. Improper wiring or
installation may damage thermostat.
VIII. CONDENSATE DRAIN LINE
The condensate drain exits the unit just above floor level at the right side
front corner of the unit. The condensate drain line is already internally
trapped therefore, no external condensate trap is required.
Install a condensate drain line of the same size as the drain fitting on the unit.
PVC plastic pipe (3/4 in. I.D.) makes an ideal condensate line (if local codes
allow).
Run condensate drain line from unit to floor drain or outside perimeter of
building per local codes.
The condensate line must have a minimum drop of 1/4" per running foot as
it leaves the unit. When a horizontal run of 15 ft. or longer is required, it may
be necessary to install a vent tee in the drain line near the unit or use a larger
diameter drain line. This is to eliminate air trapping and allow proper
condensate drainage.
Heat pumps generate condensate during both cooling and heating modes.
Condensate drain line must be protected from freezing to prevent condensate
from backing up in unit during freezing outdoor conditions.
IX. REFRIGERANT
The unit is pre-charged at the factory to the correct operating charge and
should not require adjustment. However, should an adjustment be required
or if the unit requires service, adhere to the following precautions.
WARNING: Gage ports are equipped with schrader valves. To prevent
personal injury, wear safety glasses and gloves when handling refrigerant.
CAUTION: Compressor damage may occur if system is overcharged.
See unit serial tag for amount and type of refrigerant.
WARNING: Do not vent refrigerant to atmosphere. Recover all
refrigerant before system repair or final unit disposal to avoid personal injury
or death. Use all service ports and open all flow-control devices.
X. MAINTENANCE
NOTE: It is recommended that the Vert-I-Pak be inspected and serviced
on an annual basis by a qualified technician.
If you perform maintenance on the unit yourself, remember that certain
mechanical and electrical skills, plus specialized tools are required to
properly perform maintenance. Personal injury or death may result if you
are NOT properly trained. You should call your installing dealer if you are
uncertain about your ability to perform maintenance.
WARNING: Electrical shock hazard. Turn OFF power to the system
before performing any maintenance or removing panels. Failure to do so
can result in personal injury and/or death.
A. Filters
NOTE: Dirty filters are the most common cause of inadequate heating and
cooling performance.
•
Inspect filters monthly
•
Replace disposable type filters before they become clogged
•
Use water and mild detergent to clean washable type filters
NOTE: Some filters are marked with an arrow to indicate the proper
direction of air flow through the filter. The arrow MUST point in the
direction of air flow.
XI. INSTALLATION - FINAL CHECKLIST
1.
Check to see if all duct work is sealed to unit for an airtight fit.
2.
Insure that the condensate drain line is installed and run to an
appropriate disposal site.
3.
Make sure the circuit breakers inside the unit are ON.
4.
Insure that the thermostat is level and properly installed. Heat
anticipator indicator is set to the correct setting.
5.
Test run in Heating, Cooling, and Emergency Heat mode as follows:
a.
Set fan control to ON. If fan runs, return control to AUTO setting.
This verifies fan is working properly.
b.
Set system control from OFF to COOL. Lower temperature
selector to 50°F or lower. The compressor should energize and
cool air should flow from room registers. Once cooling test is
complete, return system control to OFF setting. Wait 5 minutes.
c.
Set system control to HEAT and raise temperature selector to 80°F
or higher. Compressor should energize, and warm air should flow
from room registers.
d.
Set system control to EM HEAT (Emergency Heat). Compressor
should turn off and warm air should continue to flow from registers.
NOTE: During EM HEAT operation, temperature of air flowing from room
registers may be slightly warmer than during normal HEAT mode operation.
7.
Leave both Installation Manual and Users Manual with owner or user
of equipment.
8.
After 72 hours of operation, the unit will achieve full rated operating
performance.
