NOTE: This equipment is designed for indoor
installation ONLY.
When the disconnect switch is closed, high voltage is
present in some areas of the electrical panel. Exercise
caution when working with the energized equipment.
1. Adjust all valves to the full open position and turn
on the line power to all heat pump units.
2. Operate each unit first in the cooling mode.
Operate each heat pump in the heating
cycle immediately after checking cooling
cycle operation. A time delay will prevent the
compressor from re-starting for approximately
three minutes. Room temperature should be in
the normal range (i.e., approximately 10-27°C DB.
Loop water temperature entering the heat pumps
should be at least 4°C but not in excess of 43°C.
Refer to Table 3 for more specific information on
the operating parameters of CCE units.
NOTE: Three factors determine the operating
limits of a CCE unit: (1) return air temperature, (2)
water temperature and (3) ambient temperature.
Whenever any one of these factors is at a minimum
or maximum level, the other two factors must be at
normal levels to ensure proper unit operation. Flow
rates must be at ARI rated standards.
3. If units do not operate correctly refer to the
troubleshooting section (pg. 11). If unit cannot
be repaired, record on form on last page of this
manual and continue with start-up procedure.
Unit Start-up / Cooling
4. High Cooling -Turn the unit thermostat to the
coolest position and turn the fan speed switch to
"HI". If the unit has an optional MCO thermostat,
set the selector switch to cool. Both the fan and
compressor should run.
Check for cool air delivery at unit grille 15 minutes
after the unit is operating. List the identification
number of any machines that do not function at
this time.
Check the elevation and cleanliness of the
condensate lines; any dripping could be a sign of
a blocked line.
Operating Limits
Environment: This equipment is designed for indoor
installation ONLY.
Power Supply: A voltage variation of +/- 10% of
nameplate utilization voltage is acceptable.
CCE Unit Starting Conditions: CCE Units start and
operate in an ambient of 10°C with entering air at 10°C,
entering water at 16°C and with both air and water at
the flow rates used in the ARI Standard 13256-1 rating
test for initial start-up in winter.
Table 3 Operating Limits
Unit Start-Up
Note: Minimum air and water conditions can only
be used at ARI flow rates. CCE Units may have up to
two values at maximum or minimum with all other
parameters at normal conditions.
NOTE: These operating limits are not normal for
continuous operating conditions. It is assumed that
such a start-up is for the purpose of bringing the
building space to desired occupancy temperature.
Use the procedure outlined below to initiate proper
unit start-up:
Air Limits Cooling Heating
Min. Ambient Air 10° C 10° C
Rated Ambient Air 27° C 19° C
Max. Ambient Air 38° C 30° C
Min. Entering Air 10° C 10° C
Rated Entering Air db/wb 27/19° C 20° C
Max. Entering Air db/wb 38/28° C 27° C
Water Limits
Min. Entering Water * -1° C * -6° C
Normal Entering Water 30° C 21° C
Max. Entering Water 43° C 32° C
CCE Units
* Requires optional insulation package when operating
below the dew point.
5. Low Cooling - Disregard if your unit has only 1 fan
speed. Select low fan. Airflow should decrease
and compressor should operate.
6. Unit cycles off - Slowly turn thermostat toward
warmer position. Both fan and compressor should
shut off when thermostat set point equals room
temperature. Note: room temperature must be
below 32°C or unit will not cycle off.
