Safety Instruction
Potential safety hazards are alerted using symbol. The
symbol is used in conjunction with terms that indicate the
intensity of the hazard.
!
WARNING
This symbol indicates a potentially hazardous situation,
which if not avoided, could result in serious injury,
property damage, product damage or death.
!
CAUTION
This symbol indicates a potentially hazardous situation,
which if not avoided, may result in moderate injury or
property damage.
!
WARNING
Certied technicians or those individuals meeting
the requirements specied by NATE may use this
information. Property and product damage or
personal injury hazard may occur without such
background.
!
needed for successful installation of the unit prior to
beginning the installation.
Condensate Drain Preparation
An auxiliary drain pan must be provided by the installer
and placed under the entire unit with a separate drain
line that is properly sloped and terminated in an area
visible to the home owner. The auxiliary pans provide
extra protection to the area under the unit should the
primary and secondary drain plug up and overow. As
expressed in our product warranty; MANUFACTURER
WILL NOT BE BILLED FOR ANY STRUCTURAL
DAMAGES CAUSE BY FAILURE TO FOLLOW THIS
INSTALLATION REQUIRMENT. The drains from the
auxiliary drain pan must be installed according to the local
building codes.
!
CAUTION
The drain lines from the Auxiliary should NOT be
connected to the primary drain line of the coil.
!
WARNING
All power sources should be disconnected prior to
servicing. Failure to do so may cause personal injury or
property damage.
!
WARNING
Product designed and manufactured to permit installation
in accordance with local and national building codes.
It is the installer’s responsibility to ensure that product
is installed in strict compliance with national and local
codes. Manufacturer takes no responsibility for damage
(personal, product or property) caused due to installations
violating regulations.
Inspection
Upon receiving the product, visually inspect it for any
major shipping related damages. Shipping damages are
the carrier’s responsibility. Inspect the product labels to
verify the model number and options are in accordance
with your order. Manufacturer will not accept damage
claims for incorrectly shipped product.
!
WARNING
Do NOT install coils with plastic drain pans on any OIL or
DRUM type furnaces or applications where temperature
of the drain pan might exceed 260±5 ºF (126.6±5 ºC). A
metal pan should be specied in these applications.
Install cased coils with plastic drain pans on a level, at
surface. Incase of coils with metal drain pans slop the coil
¼” towards the drain. No such pitch is necessary in case
of plastic drain pans. Condensate drain lines must be
installed in accordance with local building codes.
The drain lines must be installed with ¼” per foot pitch
to provide free drainage. A condensate trap MUST be
installed on the primary drain line to ensure proper
drainage of the condensate. The trap must be installed in
the drain line below the bottom of the drain pan. Figure 1
illustrates the typical drain trap installation
!
CAUTION
If the drain pan is constructed of nylon or plastic; use
Teon tape to connect the drain lines to the threads in the
drain pan. DO NOT USE SOLVENT BASED PIPE DOPE.
THIS WILL REDUCE THE LIFE OF THE PAN.
Installation Preparation
Read all the instructions in this guideline carefully while
paying special attention to the WARNING and CAUTION
alerts. If any of the instructions are unclear
clarify with certied technicians. Gather all the tools

CAUTION
Some Aspen coils may include a
Schrader valve on the suction manifold. Ensure that the
Schrader valve and valve core (where present) are
protected from heat to prevent leakage.
Metering Device
Aspen coils are available with two kinds of metering
devices a) flowrator or b) TXV. Instructions below are
separated in sections according to the metering device.
Ensure that the applicable section is thoroughly read
and understood.

Figure. 1. Typical drain line trap set up
The drain pan has primary and secondary drain
connections. If a secondary drain line is required it should
be run separately from the primary and should terminate in
a highly visible location. Condensate disposal through the
secondary drain line indicates that the primary drain line is
plugged and needs cleaning. If a secondary drain line will
not be provided plug the secondary drain. The red drain
plugs are NOT to be reused without plumbers tape or putty.
The drain line connectors should be hand tightened to a
torque of approximately 35-40 lb (4-5 turns).
Use of wet rags/quenching cloth is highly recommended
to prevent weld-related damages to the casing and
Schrader valve (if present).
!
CAUTION
Some coils may include a Schrader valve on the suction
manifold. Ensure that the Schrader valve and valve
core (where present) are protected from heat to prevent
leakage.
Metering Device
Coils are available with two kinds of metering devices a)
owrator or b) TXV. Instructions below are separated in
sections according to the metering device. Ensure that the
applicable section is thoroughly read and understood.
Flowrator Coils:
Coil Installation
!
WARNING
The coil was manufactured with dry nitrogen pre-charge.
Release the pressure through the Schrader valve test
port prior to installation. If holding pressure is not present,
return coil to distributor for exchange.
Clean coil ns with degreasing agent or mild detergent
and rinse ns clean prior to installation.
!
CAUTION
Coil should be installed on the discharge side of the furnace
The refrigerant line sizes should be selected according to
the recommendations of the outdoor unit manufacturer.
All connection joints should be burr free and clean. Not
removing burr and cleaning may increase chances of a
leak. It is recommended to use a pipe cutter to remove
the spun closed end of the suction line.
To avoid damage to grommets (where present); remove
these prior to brazing by sliding over the lines. Use a
quenching cloth or allow the lines to cool down before
reinstalling the grommets.

!
CAUTION
Use Piston sizes recommended by the outdoor unit
manufacturer whenever possible. The piston should be
sized according to the capacity of the outdoor unit.
!
WARNING
Failure to install the proper piston can lead to poor system
performance and possible compressor damage.
During some installations a piston change may be
required. If so the installer MUST change the piston.
As stated earlier, use piston sizes recommended by
the outdoor unit manufacturer. If a sizing chart is not
available, use the piston size chart provided below to size
the required piston. The size of the piston is stamped on
the piston body. Use this chart when matching coil with an
outdoor unit with a different nominal capacity than the coil.
