1. Safety Instruction

WARNING

Potential safety hazards are alerted using the following symbols. The symbol is used in conjunction with terms

that indicate the intensity of the hazard.

This symbol indicates a potentially hazardous situation, which if not avoided,

could result in serious injury, property damage, product damage or death.

This symbol indicates a potentially hazardous situation, which if not avoided,

may result in moderate injury or property damage.

CAUTION

2. Inspection

3. Installation Preparation

4. Condensate Drain Preparation

Drain lines from the auxiliary drain pan

should NOT be connected to the primary

drain line of the coil.

CAUTION

Some coils have primary and secondary

drain ports on both sides of the pan to

o󰀨er installation exibility, so ensure all

threaded plugs are in present and tightened in any unused

drain ports. These may be hidden behind the coil casing

access door. Failure to do so may result in property water

damage; it is the contractor’s responsibility to ensure these

plugs are present and tight.

CAUTION

Certied technicians or those individuals

meeting the requirements specied by

NATE may use this information. Property

and product damage or personal injury hazard may occur

without such background.

WARNING

As expressed in our product warranty;

ASPEN WILL NOT BE BILLED FOR ANY

STRUCTURAL DAMAGES CAUSE BY

FAILURE TO FOLLOW THIS INSTALLATION REQUIREMENT.

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. A metal pan should be

installed in these applications.

WARNING

All power sources should be discon-

nected 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 lo-

cal and national building codes. It is the

installer’s responsibility to ensure that product is installed

in strict compliance with the aforementioned codes. Manu-

facturer assumes no responsibility for damage (personal,

product or property) caused due to installations violating

regulations.

WARNING

ü On 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 dam-

age claims for incorrectly shipped product.

ü 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 a certied technician before

proceeding. Gather all tools needed for successful installation of the

unit prior to beginning the installation. Note that absence of pres-

sure/charge does not verify a leak. Check coils for leaks prior

to installation.

ü Aspen recommends an auxiliary drain pan be provided and in-

stalled by the installing contractor, which should be properly sloped,

installed according to code, 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

overow.

ü Install coils with the drain pan and/or casing on a at, level sur-

face. Slope the coil 1/4” towards the drain. Condensate lines must

be installed in accordance with building codes. It is the contractor’s

responsibility to ensure proper condensate drainage at the time of

the installation; Aspen bears no responsibility for damages caused

by improper condensate management.

Fig 4-1. Typical drain line trap set up

ü 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.

Fig. 4-1 illustrates the typical drain trap installation. Prior to instal-

lation, ensure drain pan hole is not obstructed. Additionally, Aspen

recommends the drain lines be insulated to prevent sweating and

dripping.

INSTALLATION GUIDE CA Series - Uncased Upflow/Downflow Coils CC Series - Cased Upflow/Downflow Coils CC Series - Light Commercial Cased Upflow Coils CE Series - Cased Multi-Position Coils CM Series - Uncased Downflow Coils 1. Safety Instruction Potential safety hazards are alerted using the following symbols. The symbol is used in conjunction with terms that indicate the intensity of the hazard.
PAGE 2
Multi-position Coils are shipped from the factory for specific horizontal applications (horizontal right or horizontal left). Installer must ensure that the coil is installed in the orientation for which it was intended (horizontal drain pan side down). Failure to follow these instructions might lead to property and equipment damage. ! Use Teflon 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.
PAGE 3
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. ! CAUTION 1. Ensure suction line connection joints are burr-free and clean. Failure to do so may increase chances of a leak and introduce contaminants to the system. It is recommended to use a pipe cutter to remove the spun closed end of the suction line. 2.

II-1. Evacuate the system as per manufacturer guidelines and recommendations O-ring II-2. Turn the 13/16” nut once to release any residual pressure in the coil. I-2. Replace the Teflon O-ring (located between the halves). Discard Schrader if present. ! CAUTION II-3. After ensuring that the coil is free of any residual pressure, disassemble the flowrator body completely using two wrenches. Take great care not to distort the feeder tubes.
PAGE 5
II-8. Tighten the nut to a torque of approximately 10-30 ft-lbs. Do NOT overtighten the nut. Overtightening will impede the piston movement during operation. It is recommended that the TXV bulb be installed parallel to the ground (on a horizontal plane). The bulb position should be at 2 o’clock or 10 o’clock. Fig. 7B-2 shows the recommended position for the TXV bulb installation in the horizontal plane. II-9. If present, slide the rubber grommet back to position to prevent air leakage. 7B.

III. Field-Installed TXV Retrofit III-7. Slide attachment the nut onto the liquid line stub out (See 7A, I-3) Note: Photos are for basic illustration purposes only. Actual equipment configuration may differ from that shown. III-8. Braze the stub-out portion to the liquid line and let cool. When installing an expansion valve, it is not necessary to slide the coil out of the housing. ! WARNING Do not attempt to touch brazed joints while hot. Severe burns may result. O-ring III-1.
PAGE 7
! CAUTION 10. Coil Cleaning Instructions Using a non-bleed expansion valve may require the use of a hard-start kit. Follow the outdoor unit manufacturer’s guidelines. Aspen cased coils are equipped with a two-piece panel door to allow for cleaning and maintenance access. Remove one or both doors to access the coil for cleaning. For both copper and aluminum tube coils, it is recommended to flush with the coil with water.
