GENERAL
This installation
and start-up
instructions
literature
is for
Aquazone
TM
two-stage water source heat pump systems.
Water source heat pumps (WSHPs) are single-package
hori-
zontally and vertically
mounted units with electronic
controls
designed
for year-round
cooling
and heating.
Aquazone
WSHPs are available in the following unit configurations:
•
50PTH unit with horizontal
airflow and right, left or back
discharge
•
50PTV unit with vertical airflow and top discharge
•
50PTD
unit with vertical
airflow
and bottom
discharge
(downflow)
IMPORTANT:
The installation
of water source heat pump
units and all associated
components,
parts, and accessories
which make up the installation
shall be in accordance
with
the regulations
of ALL authorities
having jurisdiction
and
MUST conform to all applicable
codes. It is the responsi-
bility of the installing contractor
to determine
and comply
with ALL applicable codes and regulations.
INSTALLATION
Step I E Check Jobsite E Installation,
operation and
maintenance
instructions
are provided
with each unit. Before
unit start-up,
read all manuals
and become
familiar with the
unit and its operation. Thoroughly
check out the system before
operation.
Complete
the inspections
and instructions
listed
below to prepare a unit for installation.
See Table 1 for unit
physical
data.
IMPORTANT: This equipment is designed for indoor
installation ONLY. Extreme variations in temperature,
humidity and corrosive water or air will adversely affect
the unit performance, reliability and service life.
HORIZONTAL
UNIT (50PTH) -- Horizontal units are design-
ed for indoor installation only. Be sure to allow adequate space
around the unit tbr servicing. See Fig. 1 for overall unit dimen-
sions. Ret_r to Fig. 2 tbr an illustration of a typical horizontal
installation.
VERTICAL AND DOWNFLOW UNITS (50PTV, PTD) --
Vertical units are designed for indoor installations. While verti-
cal units are typically installed in a floo>level closet or a small
mechanical room, the unit access guidelines for these units are
very similar to those described for horizontal units. See Fig. 3
and 4 for overall dimensions. Refer to Fig. 5 for an example of
a typical vertical installation. Refer to Fig. 6 for a sample
downflow installation.
To avoid equipment
damage,
do not use these units as a
source of heating or cooling
during the construction
pro-
cess. The mechanical
components
and filters used in these
units quickly
become
clogged
with construction
dirt and
debris which may cause system damage.
Step
2 _
Check
Unit
_
Upon receipt
of shipment
at
the jobsite,
carefully
check the shipment
against the bill of
lading. Make sure all units have been received. Inspect the car-
ton or crating of each unit, and inspect each unit for damage.
Ensure the shipping
company
makes proper notation
of any
shortages or damage on all copies of the freight bill. Concealed
damage not discovered
during unloading
must be reported to
the shipping company within 15 days of receipt of shipment.
NOTE:
It is the responsibility
of the purchaser
to file all
necessary
claims with the shipping
company.
1. Be sure that the location chosen for unit installation pro-
vides ambient
temperatures
maintained
above freezing.
Well water
applications
are especially
susceptible
to
freezing.
2. Be sure the installation
location is isolated from sleeping
areas,
private
offices
and
other
acoustically
sensitive
spaces.
NOTE: A sound control accessory
package may be used
to help eliminate sound in sensitive spaces.
3. Check local codes to be sure a secondary
drain pan is not
required under the unit.
4. Be sure unit is mounted
at a height sufficient to provide
an adequate slope of the condensate
lines. If an appropri-
ate slope cannot be achieved,
a field-supplied
condensate
pump may be required.
5. Provide
sufficient
space for duct connection.
Do not
allow the weight of the ductwork
to rest on the unit.
6. Provide
adequate
clearance
for filter replacement
and
drain pan cleaning.
Do not allow piping, conduit, etc. to
block filter access.
7. Provide
sufficient
access
to allow
maintenance
and
servicing of the fan and fan motor, compressor
and coils.
Removal of the entire unit from the closet should not be
necessary.
