INFORMATION
Handling
Care must be taken in handling the horizontal unit and other accessories to ensure that this
equipment does not sustain any damage.
The protective shipping and packaging should remain on the unit until it is ready for
installation. During construction, the unit must not be run and shall be sheltered from
contaminants and debris such as drywall dust, wood chips, and paint that could damage the
fan or block the cooling/heating coil which may result in diminished performance.
Storage
The unit must be stored in an upright position at all times.
Failure to maintain the unit in an upright position may result in permanent damage to the unit.
Dropping the unit or exposing it to extreme shock or vibration may also result in permanent
damage to the interior components and piping.
The unit should be stored in a non-corrosive environment sheltered from conditions of
extreme temperature or humidity. Subjecting the unit to conditions of this nature may result in
significantly reduced performance, reliability, and operational life.
The unit is intended for interior use only and should be stored indoors at all times to protect it
from the elements and to help eliminate the potential growth of indoor air quality (IAQ)
contaminants.
If indoor storage is not possible, the equipment may be stored outdoors during the summer
months only, if the following provisions are met:
1. The equipment must be placed on a dry surface, or raised off the ground in a manner
which allows for air-circulation beneath the unit.
2. A waterproof tarp must be used to cover the equipment in order to provide protection
from the elements.
3. Continuous ventilation to the units must be provided to help prevent moisture
accumulation on the interior and exterior surfaces. Moisture buildup on, or within the
unit’s insulation may result in microbial growth that can lead to odors and serious
health-related IAQ problems.
4. The units must be stored in their original packaging.
5. The individual units shall not be stacked on top of one another.
6. If the unit was previously in use, ensure that all water in the coil has been blown out
and that all hose connections are plugged during storage.

LOCATION
1. Determine future horizontal mount
location with clearances shown in the
dimensioned drawings.
2. Locate the unit in an indoor area. The air
temperature surrounding and being
supplied to the unit must be above 45°F
(7°C) at all times. Do not locate the unit
in areas subject to freezing.
PLACEMENT
1. Position the unit and fasten to ceiling
ensuring the unit is leveled. Extension
Rods (not supplied by CGC) and Rubber
isolators are to be used. DO NOT block
access panels with mounting rods.
2. Meet specified clearances to provide
room for removal of all access panels.
3. Provide access to water valves (9&10)
and fittings, as well as screwdriver access
to the unit side panels, discharge air
collar, and all electrical connections.
PIPING
CAUTION: Piping must comply with all applicable
codes and regulations.
1. Install isolation valves (9 &10) at each unit to
permit unit removal for servicing.
2. DO NOT bend or kink supply lines or hoses (If
supplied). Supply and return ultra flex hoses
(7) available from the factory are fitted with
swivel joint fittings at one end to allow
removal for future servicing
NOTE: Insulation of the water piping loop is not required except where piping runs through
unheated areas or areas on the exterior of the building. The normal loop operating
temperature range is 85°F (29°C) to 120°F (49°C).

OPERATION
CAUTION:
To avoid fouled machinery, extensive unit clean up, and void warranty, do not operate units
without air filters in place, and do not operate units during the construction process.
The BULLDOG Heat Pump provides year round cooling and heating as controlled by the unit
thermostat or by a direct digital controller.
The BULLDOG Heat Pump provides cooling with a water-cooled refrigeration circuit, and
provides heating using a hydronic coil. The compressor operates in the cooling mode only and
shuts down during the heating mode providing for quieter operation, extended compressor
life, and a reduction in energy consumption.
To ensure correct operation, centralized equipment located within the building mechanical
room is automatically controlled to provide each heat pump unit with water that is at the
appropriate temperature and flow rate.

The unit circuit board incorporates six relay outputs with the following functions:
K1 –Auxiliary relay for cooling valve on a two-valve unit or heat valve on a dehumidification
unit.
K2 –Heating Relay
K3 –Alarm Relay
K4 –Compressor Relay
K5 –Low Fan or Fan Relay for belt drive units
K6 –High Fan or Compressor #2 on belt drive units
Each of these relays have, in parallel, a green LED indicator that lights up when the relay is
energized.
The circuit board incorporates digital inputs that are opto-coupled to a 24V AC source. These have
amber LED indicators located near the input locations which are lit when the input is closed. The
inputs include:
High Pressure Switch
Low Pressure Switch
Heat Call (W on thermostat terminal)
Cool Call (Y on thermostat terminal)
Fan Call (G on thermostat terminal)
Auxiliary (A on thermostat terminal)
Compressor shutdown (24V AC signal thru O/O). Providing a continuous 24V potential to
O/O will terminate and prevent compressor operation. This can be used for duty-cycling,
minimizing power consumption during an emergency power period or during sufficiently
low outdoor air temperatures which allow for free cooling –all while maintaining the
heating function.
Unit shutdown (24V AC signal thru A/O). Providing a continuous 24V AC potential to A/O
will terminate and prevent unit operation. This can be used for a night shutdown. On both
arrangements a single 24V AC signal can shutdown many units. ¼ VA is required per unit.
Finally, the board has four analog inputs provided via thermistors. These inputs are as follows:
Ta –Discharge Air Temperature
Tr –Refrigerant Temperature
Tw –Outgoing Water Temperature
Co –Condensate Level
Ta, Tr, And Tw are 10k Ohm NTP thermistors, while Co is a 100 Ohm NPT thermistor. These
Inputs do not have LED indicators.

FAN OPERATION
1. A call on “G” for fan on the thermostat terminal strip will cause the fan to operate
continuously on low fan speed through K5 on multi speed units.
2. A call on “W” for heat on the thermostat terminal strip will also cause the fan to
operate on low speed. If the heating call is still present after a 10 minute period, the
multi speed units will switch the fan to high speed through Relay K6.
3. A call on “Y” for cooling on the thermostat terminal strip will cause the fan on multi-
speed units to immediately step up to high speed through Relay K6.
4. Fan operation will terminate whenever all calls are dropped.
5. When the fan is operating at high speed, both relays are energized along with their
associated LED indicators.
HEATING OPERATION
1. A call on “W” for heat will activate the fan at low speed. It will also simultaneously
energize the heat relay K2 and its associated LED. The relay K2 will provide 24V AC fused
power directly to the heat valve.
COOL START UP
1. A call on “Y” for cooling initiates a series of checks prior to the start up of the
compressor. These checks include:
a. Power ON timer –Compressor operation is delayed for approximately 5 minutes
after restoration of power. This prevents all units from coming on line at the
same time when power is restored. It also prevents compressor jolting with
intermittent power.
b. Anti-Recycle timer –There is a 5-minute anti-recycle delay timer that allows the
refrigeration cycle to achieve pressure equalization so that the compressor is
unloaded upon start up.
c. High Pressure Switch –The high refrigerant pressure switch must be closed prior
to start. LED 11 will be ON.
d. Low Pressure Switch –The low pressure switch operates primarily as a loss of
charge protector. It must be closed for compressor start up and its LED 12 will
be ON. The pressure switch has a 5 minute time ignore subsequent to start-up.
In some situations, particularly when the unit is cold, the pressure switch will
open during start-up. If the switch does not remake with the 5 minute ignore
period, the compressor will immediately be stopped.
e. Air temperature sensor Ta –Sensor Ta will prevent compressor operation if the
air flowing through the unit is below 55F (15C).
