Carrier 40FS Bedienungsanleitung PDF herunterladen (Seite 3)

Models 28VQ,HQ coils and 40FS heaters are for

use in cooling-only and/or cooling and electric

heating systems. The 28VQ and HQ coils are also

for use in heat pump systems with 38HQ or 40FQ

electric heaters. Model 28TQ coil is for installation

in 38TQ 2-speed heat pump systems. The 28QX coil

is for solar-assisted heat pump systems. The 28VH

coil application is with Model 40FS075 only.

Fan section, coil and electric heater are tested

and approved for installation in unconditioned

space per ARI Standard (80 F db, 75 F wb indoor

temperature; 80 F db outdoor temperature). Insu

late supply and return air ductwork in uncondi

tioned space. If conditions exceed the ARI Stand

ard, additional insulation with vapor barrier may

be required for the unit.

Fan Sections 40FS can be positioned to discharge

air upward (upflow), horizontally, or downward

^(downflow), except for sizes 075, 120 which cannot

be used in downflow applications, and are suitable

for “Attic-Type” installations.

The 28 Series Coils are approved as draw-thru

(airflow) units only with the 40FS fan section. Install

coils in draw-thru position; heater in blow-thru

position. Therefore, coil must be attached to air inlet

end of fan section. As indicated in Table 3, per

missible coil airflow position(s) in system are:

28TQ — upflow, downflow or horizontal; 28VQ —

upflow or downflow; 28HQ — horizontal; 28QX —

upflow or horizontal; 28VH002 — horizontal or

^upflow with 40FS075 only, upflow with 40FS120

only.

Assembly of coils to 40FS fan section, electric

heater and filter section is described in this booklet.

For further coil information, see 28 Series installa

tion data.

COIL CONDENSATE DRAINAGE (for any unit

assembly installed above an occupied or usable

space) — In addition to normal condensate drain

line connection, install an auxiliary condensate pan

under entire unit assembly. Route drain line to any

drain that is visible to occupant. In 28 VH coil appli

cations, only the drain pan needed should be used.

See 28VH Installation Instructions.

Under prolonged high humidity conditions, elimi

nator plates may be required on downflow applica

tions. Horizontal coil installation may also require

special condensate removal methods. See Coil In

stallation Data.

Accessory Electric Heater is used with 40FS,

208/230-volt fan section. See Electrical Data and

Wiring table for fan section/electric heater usage.

Use electric heater as a blow-thru unit only by

attaching heater to air discharge end of 40FS fan

section in any of the 3 positions. Electric heater

has both heating and cooling controls including a

40-va or 60-va control circuit transformer, indoor

fan relay and low-voltage terminal strip.

MODELS 40FS916320 AND 40FS916500EH,

GM AND HV — These heaters are approved for

downflow usage but require the use of adapters

(downflow support angles) to support fan section

weight. See Installation, Heating Unit Assembly.

Filter Section is shipped taped to air inlet end of

fan section. Filter section includes a reversible

filter rack with 5/8-in. duct connection flanges. On

most unit assemblies the filter section can be

attached to unit with flanges exposed or turned over

so flanges are inside unit. The permanent one-in.

filter media pulls out (Fig. 1) for easy removal and

cleaning.

Cooling Control Kit is an accessory for 40FS,

208/230-volt fan sections used in cooling-only in

stallations. The kit contains a 40-va transformer, fan

deck filler panels, indoor fan relay and low-voltage

terminal strip. See Fig. 11, and cooling control kit

installation on page 9. Because accessory electric

heaters come equipped with cooling controls listed

above (plus required heating controls), a cooling

control kit is not required when electric heater is

used. An accessory humidity control kit is required

for use in 28TQ 2-speed installations. See Step 7

and Fig. 12.

INSTALLATION

Step 1 — Inspect Equipment — File claim with

shipping company if shipment is damaged or

incomplete.

Step 2 — Determine Position of Unit by Air

flow Direction — See Table 3 and Fig. 2, 3, 4 and

5. Ensure access panels on all units face front before

and after unit assembly.

Step 3 — Assemble Required Unit — Follow

assembly procedure below for required unit. On

downflow unit assemblies, loosen or remove fan

motor mounting bolts and rotate fan motor so

oiling holes are a minimum of 45° above horizontal

center line of motor.

Fasteners for assembling units are shipped in a

bag inside of fan section or inside electric heater

enclosure. Use the no. 10 serrated hex head sheet

metal screws (or equivalent) provided, where indi

cated in unit assembly instructions below, to ensure

proper electrical ground continuity.

and PA when used with fan sections 40FS075.

-»40FS120. 40FS200 and 40FS220 — Position fan

section for upflow air direction. (Accessory flange

deck40FS900391 or40FS900401 required.) Setelec-

tric heater on air discharge end of fan section.

Attach heater to fan section with 5 no. 8-32 self

threading screws provided. Clearance holes for

screws are provided on each side (2) and hack (1) of

fan section and engagement holes on heater.

Electric Heater Models 40FS916320. 40FS916330

and 40FS9165Q0EH. GM and HV — Position fan

section for upflow air direction. Mount heater on

fan section supply air duct connection flanges, and

attach with 4 sheet metal screws. Four clearance

holes for screws, provided on heater cabinet, can

be used as template for drilling engagement holes

in duct flanges as required. See Fig. 3. Assembly

may be aided by first removing top flange deck

from fan section (2 screws hold flange deck in place).

Assembled heater and flange deck can then be

resecured to fan section. Reposition plug buttons
