Step 9 - Install All Accessories - Bryant DuraPac 558F Installation & Service Instructions Manual

2. Locate the minimum position (MIN POS) potentiome-
ter. Turn the potentiometer full CCW to fully close the
outdoor air dampers. Turn the potentiometer gradu-
ally clockwise (CW) to the desired position. See Fig. 17.
3. Replace the filter access panel. See Fig. 19. Ensure
the filter access panel is securely engaged.
4. Calculate the minimum
EconoMi$er.
a. Calculate % of outside air using the following
formula.
% Outdoor air through EconoMi$er
% Outdoor Mixture Temp – Return Air Temp
=
air
Outdoor Temp – Return Air Temp
b. Multiply total CFM by percentage outdoor air,
this gives outdoor air volume in CFM.
WARNING: Personal Injury Hazard. Avoid possi-
ble injury by keeping fingers away from damper blades.
IX. STEP 9 — INSTALL ALL ACCESSORIES
After all the factory-installed options have been adjusted,

See Fig. 26 for baffle details. Use 20-gage, galvanized sheet
metal, or similar corrosion-resistant metal for baffles. Use
field-supplied screws to attach baffles to unit. Screws should

CAUTION: To avoid damage to the refrigerant
the
coils and electrical components, use recommended
screw sizes only. Use care when drilling holes.
Install Motormaster I Controls
One Motormaster I control is required on size 180 and 210
units. The Motormaster I control must be used in conjunction
with the Accessory Fan Motor Sequencing Kit and Winter
Start Kit (purchased separately). The Motormaster I device
controls outdoor fan no. 1 while outdoor fans no. 2 and 3 are
sequenced off by the Accessory Fan Motor Sequencing Kit.
Accessory Fan Motor Sequencing Kit — Install the Accessory
Fan Motor Sequencing Kit per instruction supplied with
accessory (purchased separately).
Winter Start Time Delay Relay Kit — Install the kit per the in-
structions supplied with the accessory (purchased separately).
Sensor Assembly — Install the sensor assembly in the loca-
tion shown in Fig. 27.
Motor Mount — To ensure proper fan height, replace the
existing motor mount with the new motor mount provided
with accessory.
