OUTDOOR THERMOSTATS

(All installations of this heat pump in Manufactured Homes built
per HUD standards SHALL have an outdoor thermostat installed at
the time of installation by the installer. In accordance with HUD
std. 3280.714 (a) (1) (ii). Outdoor thermostat, Part number 3024-
6881/D or equivalent shall be used and should be ordered at your
nearest UPG Parts Source)

. See last page of these instructions.

Select the proper location for mounting the outdoor thermostat (see
instructions packed with outdoor thermostat).

INDOOR UNITS

Install the indoor coil in the furnace or air handler according to the
installation instructions packed with each component.

REFRIGERANT LINE

1. Refer to the tabular data sheet for the correct line set kit part num-

ber for your unit.

a. Check the size of the pre-charged refrigerant lines to insure that

they are correct for the model being installed.

b. Check the final routing of the tubing, and insure tubing will be of

adequate length, with allowance for connection at the coil and
outdoor unit.

The line set part number, size, and length are shown in the tabular data
sheet. Do not use any line sets other than those shown. Refer to the
appropriate line set Installation Manual.

2. Copper tubing will work-harden (for copper tubing only).

a. The pre-charged tubing should be handled carefully.
b. Do not bend or work the tubing any more than necessary. (The

larger size tubing 3/4" for example, will work-harden rapidly as it
is formed. As the tubing becomes harder, it is more susceptible to
kinking and damage).

3. Forming Copper (for copper tubing only).

a. No attempt should be made to bend the suction line in a shorter

radius than 12". See Figure 2.

4. How to dispose of excess tubing.

a. Tubing may be longer than required. Coil excess tubing nearer

the indoor coil rather than the outdoor unit.

b. Excess tubing must be coiled horizontally so the flow of refriger-

ant is from top to bottom of the coil and toward the outdoor unit.
Another method is to form a horizontal “U” large enough to take
care of excess. See Figure 3.

5. Slope tubing toward outdoor unit.

a. When the coil is above the outdoor unit, the suction line should be

sloped with a fall of a least 1/4" per foot toward the outdoor unit.

b. When the outdoor unit is above the coil, the tubing should be

sloped downward along lateral distance to the bottom, or from the
vertical riser.

6. Insulation of suction line.

a. Standard suction lines come pre-insulated from the factory with 3/

8" closed cell insulation, adequate for average installations.

b. Do not insulate liquid and suction lines together.

c. Liquid lines should not be insulated.

d. Liquid lines should not be in bare contact with suction line. See

Figure 4.

Failure to do so or using a substitute drier or a granular type may
result in damage to the equipment.

All

Do not remove protective caps from couplings until pre-charged lines
are routed and ready for final connection. Protective caps prevent dirt
from entering couplings and contaminating system when connected
together.

Excess Tubing

In regions of extreme temperatures and humidity, additional insula-
tion may be required to prevent excessive condensation and serious
loss of capacity.
