Overview
Ice Air Vertical Stack Water Source Heat Pumps are quality units, which should only be installed by a trained professional. Please ensure all
sections are read thoroughly before installing the unit.
Application Note
It is important for heating/cooling systems to be properly sized for each application in order to achieve desired temperature and humidity
levels. It is highly recommended that a professional engineer match the WSHP units you are about to install with the building structure and
climate.
Inspection
1. Check the shipment against the Bill of Lading. Ensure all components are intact upon delivery and free from damage. Note any damage on
the delivering carrier’s Bill of Lading*.
2. The Ice Air unit(s) arrive prefabricated with an enclosure. Ensure both the unit and the enclosure are properly attached.
3. Make sure the floor is level in both directions so the unit’s airflow will be aligned. Confirm adequate drainage is available to ensure
adequate and continuous water flow during unit operation.
4. Remove the access panel is BEFORE installing.
5. Verify amperage to the unit(s) is correct and the unit can reach the power supply.
* Purchaser’s responsibility includes filing all claims with the delivering carrier in a timely fashion.

Before You Begin
1. Locate the unit where it can evenly
distribute air throughout the room
without obstructions. Units should be
installed no closer than 12” apart when
two units are side by side. A vertical
clearance of 60” should be maintained
between units.
2. Ensure the wall is structurally sound to
support the weight of the unit.
3. Adequate and continuous water flow
must be maintained for proper and
safe unit operation. Ensure adequate
drainage is also available.
4. Follow all applicable codes for
installation.
5. Dedicated electrical circuitry and power
supply is required to properly energize
the Ice Air unit. Verify the amperage of
the dedicated electrical service to the
unit is correct and the unit can reach the
power supply.
6. Position the unit so the air filter can
be removed easily and required
maintenance can be performed without
interference.
7. A minimum obstructed distance of 36”
should be kept around the unit.
IMPORTANT: To avoid permanent damage
to the unit, DO NOT operate during
construction in an open space or as a
supplemental heating and cooling source
during construction.
Inspection
1. Upon receipt of the equipment, carefully
check the shipment again on the Bill of
Lading.
2. Make sure all units have been received.
3. Inspect the packaging for any damage.
4. Ensure that any damage is noted on the
delivering carrier’s Bill of Lading.

Installation
Casing and Riser Installation Congurations
Riser system design is the responsibility of the building mechanical designer and/or the installing contractor. Because it affects individual unit
performance and efficiency, it is important that the system be properly designed, installed and balanced prior to operation of the equipment.
IMPORTANT: Please do not attempt to install risers without the help of a certified plumber.

Riser Sizing and Insulation
Riser sizing is generally based on the water flow requirements of
each unit and will vary depending on unit location within the building
(units on higher and lower floors that tie into the same riser column
may require different size risers, depending on the piping system
chosen). The riser material, diameter, length and insulation thickness
must be determined for each unit based on its positioning within the
building and the overall system requirements.
IMPORTANT: Please consult an engineer before proceeding with
riser installation.
Riser Expansion
Generally, in medium to high-rise buildings, allowances must be
made for pipe expansion. In applications supplemented with factory-
or field-supplied between floor riser extensions, assemble and install
extensions before installing the unit cabinet.
NOTES: Riser assemblies are designed to accommodate a maximum
of 1-1/8” expansion and contraction up to a total movement of
2-1/4”. If the total calculated rise expansion exceeds 2-1/4”,
expansion devices must be used (field provided).
All riser modification necessitated by variations in floor-to-floor
dimensions, including cutting off or extending risers, or providing
extensions, are the sole responsibility of the installing contractor.
In cases where piping movement is expected to exceed the factory
allowances, additional expansion compensation must be made to
the riser system in the field. The graph below displays the expansion
characteristics of risers compared to water temperature differential.
Assuming a minimum water temperature of 20°F and a maximum
water temperature of 120°F, the temperature difference of 100°F
indicates 90 feet of riser will expand or contract 1”. To eliminate
stress, a riser system must be anchored at least once to the building
structure. Technical information on pipe expansion, contraction and
anchoring can be found in the ASHRAE HVAC Systems and Equip-
ment Handbook. Riser expansion and the anchoring of both the riser
system and each unit is the responsibility of the design engineer and
installing contractor.
Riser Connection
Install cabinet with risers as follows:
1. Move cabinet into position. CAUTION: Keep risers off the floor
while moving the cabinet.
2. Be sure that all the copper fittings are clean and free of dirt.
3. Raise the cabinet upright and lower it so the attached risers
fit into the risers from the unit previously installed on the floor
below.
NOTE: The top of each riser is equipped with a 3” deep swaged
connection. There is sufficient extension at the bottom to allow
insertion of approximately 2” of the riser into the swaged top of
the riser below.
4. Center the risers in the pipe chase and shim the unit cabinet to
a level position. Plumb the risers in two planes to assure proper
unit operation and condensate drainage.
5. Attach the cabinet assembly to the floor and to the building
structure on at least two sides using sheet metal angles (field
provided).
NOTE: A field provided base vibration dampening pad can be
used to help eliminate transfer of any vibration from the unit to
the building structure. If vibration dampening pads are used,
some rough-in dimensional changes will need to be considered
before installation due to the type and thickness of the pads.
Additional anchorage can be provided by installing brackets at
the top of the cabinet (field provided).
6. DO NOT attach drywall studs to the equipment cabinet.
7. When all units on a riser are anchored into place, complete riser
joints as follows:
– Verify that all riser joints are vertically aligned and that risers
penetrate at least 1” into the swaged joint of the riser below.
DO NOT let riser joint bottom out.
– Braze riser joints with a high-temperature alloy using proper
Phos-copper or Silfos. Soft solder 50-50, 60-40, 85-15,
95-5 and low temperature alloys are not suitable riser weld
materials.
– Anchor built-in risers to the building structure with at least
one contact point. To accommodate vertical expansion and
contraction DO NOT fasten risers rigidly within the unit.
– Verify that unit shut-off valves are closed. DO NOT OPEN
VALVES until the system has been cleaned and flushed.
– Flush system, refer to “System Cleaning and Flushing” ection
of this manual for more information.
– Install vents in piping loop as required to bleed the system of
air accumulated during installation.

Installing Modular Risers
Ice Air Modular Riser System is a unique riser system designed
to increase efficiency for the contractor and building mechanical
designer. Each riser set is encased and palletized separately prior to
shipping, allowing minimal installation efforts.
In order to install the Modular Riser System, carefully review the
mechanical plans and place the risers in the designated location.
Once the system is in place, the exposed joints allow for easy
pressure testing. To attach the unit, align the unit’s cabinet to each
riser set and ensure the riser stubs correspond to the unit’s piping
diagram.
NOTE: Riser dimensions vary by floor and project.

Storage
• Ensure all equipment is stored in a clean and dry area.
• Ensure all equipment is properly covered and protected while at
job site. Keep coverings on units until installation is complete.
Precautions must be taken in areas where construction is still
underway to prevent any damage to the equipment.
Casing Pre-Installation
• Ensure all nameplate data is accurate.
• Check that all electrical connections are clean and secure.
• Remove supply air opening knockouts as shown on building
plans.
• Remaining knockouts must remain covered. Do not remove
unused knockouts.
• Remove correct riser knockouts.
• Apply vibration isolation pads to the bottom of the cabinet (if
applicable).
Chassis Pre-Installation
• Ensure refrigerant circuit is free of all damages and kinks.
• Check that all electrical connections are clean and secure.
