Machine Room Temperature and Ventilation -

Locate compressor or condensing unit in well ventilated space. Check code requirements. Pro vide forced ventilation thru ductwork when natural ventilation is inadequate.

Protect water-cooled condensers, water lines, and accessories from freezing during winter shutdown periods.

PREPARE FOUNDATION

Fasten compressor to: (a) steel base and vibra tion isolators on floor; (b) steel base and condenser support stand or (c) concrete base.

Floor Foundations - Locate compressors over

joists or beams wherever possible.

Weak floors in old buildings must be reinforced with steel beams or timbers to support the heavy compressors or condensing units. Use care in placing supports to avoid transmitting objection able vibrations to other areas.

Concrete Foundations one to two times the weight

of the machinery they support will absorb vibra tion. See Fig. 8 and Tables 7 and 8 for recom mended dimensions. Let foundation set sufficiently before compressor is installed (approximately 3

days). Allow for 3/8 inch to 1/2 inch grout after compressor is installed.

Heavy aggregate concrete weighs about 150

pounds per cubic foot.

INSPECT UNIT

Inspect shipment for damage or loss. File

claim immediately with shipping company for any loss or damage.

Move and rig unit carefully to prevent damage to gages, mounting brackets, refrigerant piping and connections.

COMPRESSOR INSTALLATION

Compressor on Steel Base and Vibration Isolators on Floor — Install vibration isolators on one end of

unit at a time. See Fig. 9 for typical vibration isolator mounting.

Motor fastening set supplied with all com pressors (except 5F20,30) includes several beveled washers. Washers are installed under heads of

capscrews used to fasten unit base to vibration

isolators or floor.

Position compressor and motor on frame and

check height of vibration isolators. Shim between

vibration isolators and floor to level compressor

base Secure vibration isolators to floor. If beveled washer (Fig. 9) is omitted, end of capscrew may strike the floor and cause vibration isolator to rupture when it is secured to floor.

Condenser and Stand Assembly - Place cast iron

condenser stands in their correct location. Make distance ”C" (Fig. 10) between tapped holes on top of stand equal to holes in lower flange of com pressor unit base. See Table 9 for dimensions.

Shipping caps are soldered to the 5F20,30,40 and 60 condensers at the factory. To remove caps turn condensers upside down. This prevents solder from falling into condensers.

Bolt lower support strap loosely to lower side of each condenser stand.

Place condenser on stands with front water head at compressor end of base. Position con-

CRANKCASE HEATER

Energizing crankcase heater helps prevent oil and refrigerant from mixing and accumulating in crankcase when compressor is off.

Wire heater to relay or set of normally closed contacts in compressor starter so it will be de energized when compressor is operating.

Installation of Heaters- Remove rubber plug from

crankcase heater casing (see Fig, 1 thru 4).

Insert heater element entirely into casing. Element should fit snugly, not loosely.

Wire in accordance with local codes and dia gram (Fig. 11).

Relay Coil voltage is determined by control cir

cuit voltage which must be specified when ordering relays.

Mount relays vertically.

When crankcase heater is installed, system can

operate on a single pumpout cycle as shown in

schematic. Fig. 11.

Crankcase heater packages are given in Table

10 and corresponding relay is in Table 11. When two heaters are usedona 5H80or 120 compressor only one relay is required.

Place Fabrica strips (see Fig. 10), between

condenser and upper straps. Tighten strap bolts

to secure condenser to stand. NOTE; Use lower

straps only for 5F20 and 30 units. Place the two extra strips of Fabrica between top of condenser and base. Assemble discharge line as described

above.

Compressor Bolted to Concrete Base - See Fig. 8.

Set compressor level on foundation bolts. (Level in two directions.) Removal of discharge shut-off valve exposes face of mounting flange on com pressor which can be used as a leveling pad. Lo cate and level motor slide rails. Provide for 3/8 inch to 1/2 inch grout. Tighten foundation bolts handtight. Do not use wrench.

Wet top of concrete, pour grout and tamp to fill all spaces between machinery and concrete. Allow grout to dry slightly then trowel smooth.

Suggested mixture for grout is one part Port

land cement to two or three parts of sharp sand.

Tighten foundation bolts moderately tight when grout has hardened for 24 to 36 hours. Overtight ening bolts may cause compressor misalignment.

COMPRESSOR OPERATION

Motor Rotation - Start motor before connecting to

compressor. Rotation direction must be same as

arrow cast on pump cover or plate attached near

pump end bearing housing. To rotate compressor

in opposite direction the manually reversible oil

pump must be reversed as follows:

5H120 AND 126; ALL 5F COMPRESSORS - Remove 6 capscrews from oil pump cover. Do not damage gasket. Rotate cover 180° and replace. Arrow will now be on top and show new direction of rotation,

5H40,46,60,66,80 AND 86 COMPRESSORS - Drain oil below level of end bell cover. Remove end bell assembly and pump end cover. Rotate cover 180° and replace. Reverse direction of external arrow (shows compressor rotation without removing end bell). Arrow on pump end cover must match arrow on main bearing housing. Replace end bell and

refill with specified oil.

units (except 5F20,30) includes motor blocks and

shims for motor alignment; capscrews, plate washers and lock washers for fastening motor to base; taper dowel pins for securing motor position on base (after alignment); beveled washers for fastening unit base to vibration isolators or floor.

Install and Align Belt Drive — Clean motor and

compressor shafts, flywheel and motor pulley bores with fine emery cloth.

Install motor pulley, flywheel and keys tightly

on shafts.

Slide motor forward on rails to install belt. Line

up flywheel and motor pulley with a straight edge

Fig, 12 - Correct Belt Alignment

or string (Fig. 12) or by placing a round rod in belt grooves. Slide motor pulley on shaft to correct any

parallel misalignment. Loosen motor hold-down bolts and turn motor frame to correct any angular misalignment.

Move motor backward with adjusting bolts to tighten belts. Tighten belts just enough to prevent slippage.

Determine belt tension by (a) loosening belts

until they slip when motor starts (belt squeals),

then tighten enough to eliminate slippage, (b) amount belt is depressed at center of span (heavier belts deflect approximately 1 inch for a 24-inch span; lighter belts or longer span deflect propor

tionately more)

Install Direct Drive — Instructions for installation

are in the coupling package

Securing Motor to Base — Align motor and

compressor. Drill and ream two holes thru motor feet and base. Secure motor to base with two

#6 X 2-1/2 taper dowel pins provided in motor

fastening set. Locate holes diagonally opposite motor feet. Use 9/32-inch diameter drill and #6 taper reamer.

REFRIGERANT PIPING

Refer to Carrier System Design Manual, Part

3 for proper piping techniques.

Venting - Replace vent plugs (front and rear heads)

and drain plug (front head) with nipples and valves

if frequent draining of condenser (water side) is

desired.

Refrigerant Drier - See System Design Manual,

Part 3, Page No. 3-75.

Felt Filter - Install felt filter (supplied with com

pressor) in suction line screen. Remove after 50 hours of compressor operation. If dirty, clean with kerosene or neutral spirits and replace for another

50 hours operation. If filter is clean, leave it out.

Indicate on tag that filter has been cleaned and

reinstalled.

569

Oil Filter should be replaced after 50 hours opera

tion and whenever oil is changed or becomes dirty.

Oil Separator (Optional) - Install separator so its

weight is carried by supports or hangers and not piping.

Connect separator inlet to compressor dis charge and separator outlet to condenser. Con nect oil return line (1/4-inch or 3/8-inch copper tubing) between separator and compressor crank case. Make line long enough to be flexible and free from strain. Connect oil return line to upper oil and gas equalizer line connection (if available) on compressor. When two compressors are installed in parallel, connect oil return line to oil equalizer

line between the two compressors. Install shut

off valve in oil return line to facilitate service and

minimize refrigerant loss.

An additional oil charge is required when an oil separator is used. Watch oil level and check

separator float valve operation during initial compressor operation. Follow instructions fur nished with oil separator.

Compressor Muffler (Optional) - Mufflers are in

cluded in condenser piping packages for all 5H condensing units. They are recommended for all remote installations. Install mufflers either hori zontally or vertically (refrigerant flow downward).

Arrow on muffler indicates flow direction. Place outlet at bottom in horizontal installations to pre vent trapping oil. Locate muffler as close as pos

sible to compressor.

Special Handhole Cover Plates (Optional) have

tapped holes for connecting equalizer lines. When operating compressors in parallel, replace stan dard covers with special covers. See Fig. 13.

5H120 AND 126 - Tapped cover plate is standard on 5H120 and 126 compressors. Use only lower

connection for oil equalization. Connect gas equal-

ization line at flange connection. See Fig. 14. Mating flange for 1-1/8 inch OD is Mueler part no. A-515; gasket no. A-5152.

5F20 AND 30 compressors have no special tapped cover plate. Use opening for oil sight glass with

1-1/8-inch line for gas and oil equalization. For additional equalization, run a 3/8-inch line to oil fill plug. See Fig. 15.

Cooled Heads - When used, install water-cooled

heads and piping as shown in Fig. 16.

5F20,30,40,60; 5H40,46,60,66,80 AND 86 com

pressors have one water circuit piped to flow in

either direction. See Fig. 16. 5H120 AND 126 compressors have two parallel

circuits with two 1/2-inch IPS water inlet con nections and one 1/2-inch IPS water outlet con nection. See Fig. 16.

Install manually operated valve in each water circuit, adjusted for 100 F maximum leaving water temperature.

CONDENSER WATER PIPING

Piping - Use piping for maximum pass operation,

Fig. 17, when ample water pressure is available. Use minimum pass operation. Fig. 18, for low water pressure or when cooling tower is used.

Water Regulating Valve Adjustment - Set shut-off

point at least 10 F below condensing temperature to be maintained at maximum load, but not above

90 F. Select shut-off point high enough to close valve when unit is not operating.

LUBRICATION

Compressors are charged with oil at the fac

tory. Oil quantities are given in Table 12.

Maintain oil level at center of sight glass. When adding oil, use only a dehydrated, wax-

free refrigeration grade oil of suitable viscosity.

Compressors are charged with refrigeration grade oil (Carrier No. PP36) for evaporator tem peratures above -45 F. When evaporator tempera ture is -40 or below, replace oil with Carrier

No. PP33.

REFRIGERANT CHARGING

Refer to 5F,H Start-Up and Service Instructions and Carrier Standard Service Techniques Manual, Chapter 1, for complete charging information.

Pneumatic Control may be connected to capacity control valve

on all 5F,H compressors except 5F20 and 5F30. A 1/4-inch IPS connection is located above the capacity control valve on each compressor.

The capacity control valve is set as described in the Start-Up and Service book.

The pneumatic control, in effect, resets the control point upward by the amount of air pressure applied. Do not apply more than 25 psig. For example, if system suction pressure is 40 psig and the control point setting is 35 psig, an applied air pressure of 5 psig causes first cylinder to unload.
