AIR CONDITIONING & HEAT PUMP INDOOR COILS

INTRODUCTION

Please note that HUD Manufactured Home Construction and Safety Standard Section 3280.714, paragraph (a) and subparagraph
(4) and (5) clearly specifies when a cooling or heat pump coil and air conditioner blower are installed with a furnace or heating
appliance they shall be tested and listed in combination for heating and safety performance by a nationally recognized testing
agency(ies). Additionally, the cooling or heat pump systems to be installed in Manufactured Housing shall be certified, listed and
rated based on US Department of Energy test procedures which are listed by AHRI and shall be tested and listed in combination
for heating and safety performance by a nationally recognized testing agency(ies).

Mortex coils are designed specifically for use with various models of manufactured housing gas or electric furnaces in both down-flow
and up-flow applications. A different pan will be required on up flow oil furnaces.

These instructions are primarily intended to assist qualified individuals trained and experienced in the proper installation of this type of
equipment. Some state codes require installation and service personnel to be licensed. Refer to authorities having jurisdiction for
additional guidance. Remember that the Clean Air Act of 1990 requires technician certification for handling refrigerant.

Some Mortex coils have a TXV as the metering

device. However, the sensor bulb is not mounted

due to potential heat damage and / or proper bulb

location. Therefore, after the suction and liquid

line have been properly connected to the coil the

bulb can be mounted on the suction. Many times,

due to space limitations in the manufactured

housing applications it will require the sensor

bulb to be mounted vertically. If that is the case

the bulb should be located at least 6” away from

and bend (elbow) and fastened on the tubing side

opposite the plane of the bend. The bulb should

be insulated using the thermal insulation to

protect it from the effects of the surrounding

ambient temperature. (SEE PAGE 7)

GENERAL COIL INSTALLATION NOTES

1.

On a quick connect coil, test for pressure by pushing
against the diaphragm located inside the quick connect
fitting on the suction manifold. If you are not able to
depress the diaphragm, the coil contains a Nitrogen
holding charge.
To test for pressure on a sweat connect coil, remove
the cap or flare nut on the Schrader fitting and depress
the core valve located on the suction manifold.

2. The blower and duct system must be properly

All Mortex coils are shipped pressurized with
Nitrogen. Coils with sweat or quick connect
fittings are shipped with a nitrogen holding
charge.

ALL COILS SHOULD BE CHECKED FOR
PRESSURE BEFORE LEAVING THE
DISTRIBUTOR OR BEFORE INSTALLATION!
IF THERE IS NO PRESSURE PRESENT, THE
COIL MAY HAVE DEVELOPED A LEAK
DURING SHIPMENT AND SHOULD BE
RETURNED TO THE POINT OF PURCHASE
FOR EXCHANGE.

regulations requiring third party approvals.

Efficiency and capacity ratings as required by

the outdoor units. These coil ratings are based on

air quantities consistent with those that are

condition and heat pump applications.

required CFM needed for rated cooling capacity
or upgrade the blower assembly to attain the
proper CFM. Return air filters of generous size
must be provided, in order to avoid contaminating
the coil, blower and ductwork, or restricting
necessary airflow. Failure to deliver the proper air
flow across the indoor coil will cause system
and/or component problems, i.e. TXV
performance problems.

3. It is essential that the indoor coil and outdoor

unit be properly matched and charged with
the proper amount of refrigerant. Incorrect

charge levels will result in inefficient operation.
See more details in installation instructions for the
outdoor unit.

4. For optimum performance and efficiency of air
conditioning or heat pump coils, adjust system
charge and/or superheat/subcooling as
recommended by outdoor unit manufacturers.
Procedures will differ between manufacturers.

5. It is recommended that the coil be sprayed with
liquid detergent thoroughly and rinsed thoroughly
before installation to assure proper drainage of
condensate from the coil fins to eliminate water
blowoff and to assure maximum coil
performance. If not sprayed, approximately 50
hours of break in time is required to achieve the
same results.
