SAFETY CONSIDERATIONS

Installing, starting up, and servicing this equipment can

be hazardous due to system pressures, electrical components

and equipment location (elevated structures, etc.).

Only trained, qualiﬁed installers and service mechanics

should install, start up, and service this equipment.

Untrained personnel can perform basic maintenance func-

tions such as cleaning coils, and cleaning and replacing

ﬁlters. All other operations should be performed by trained

service personnel.

When working on the equipment, observe precautions in

the literature and on tags, stickers, and labels attached to the

equipment.

• Follow all safety codes.

• Wear safety glasses and work gloves.

• Use care in handling, rigging, and setting bulky

equipment.

Be sure all power to equipment is shut off before per-

forming maintenance or service. More than one discon-

nect may be present.

PRE-INSTALLATION

Moving and Storage —

To transfer unit from truck to

storage site, use a fork truck. Do not stack units more than

2 high during storage. If unit is to be stored for more than

2 weeks before installation, choose a level, dry storage site

free from vibration. Do not remove plastic wrap or skid from

unit until ﬁnal installation.

Rigging — All 40RM Series units can be rigged by us-

ing the shipping skid. Units are shipped fully assembled. Do

not remove shipping skids or protective covering until unit

is ready for ﬁnal placement; damage to bottom panels can

result. Use slings and spreader bars as applicable to lift unit.

INSTALLATION

General —

Allow 2

⁄

ft at front and side of unit for

service clearance and airﬂow. For units equipped with an econo-

mizer, refer to the accessory installation instructions for ad-

ditional clearance requirements. Be sure ﬂoor, wall, or ceil-

ing can support unit weight (Tables 1A-1F). See

Fig. 1A-1C for dimensions.

Uncrating — Move unit as near as possible to ﬁnal lo-

cation before removing shipping skid.

Remove metal banding, top skid, and plastic wrap. Ex-

amine unit for shipping damage. If shipping damage is

evident, ﬁle claim with transportation agency. Remove base

skid just prior to actual installation.

Check nameplate information against available power

supply and model number description in Fig. 2.

Accessories — Refer to instructions shipped with each

accessory for speciﬁc information.

Unit Isolation — Where extremely quiet operation is essential, install isolators between floor and base of unit, or between ceiling and top section of unit. Be sure that unit is level and adequately supported. Use channels at front and sides of unit for reference points when leveling. Refrigerant Piping — See Tables 1A, 1B, 1D, 1E for refrigerant pipe connection sizes. For ease in brazing, it is recommended that all internal solder joints be made before unit is placed in final position.

IMPORTANT: Never attach the sensor to the suction manifold. Do NOT mount the sensor on a trapped portion of the suction line. 40RM Series evaporator coils have a face-split design. Ensure that lower circuit of coil is first on/last off when connected to the condensing unit and/or system controls. See Fig. 6. External TXV equalizer connections are provided and factorybrazed into the coil suction manifolds.

Legend and Notes for Tables 10C and 10D Replacing Filters — Filters can be removed and installed from either side of the unit. Install new filters in units that have one fan as follows: 1. Remove the side access panel (retain screws). 2. Remove the filter retainer clip. 3. Remove old filters by tilting them and lifting them out of the filter track. See Fig. 12 and 22. 4. Reverse the procedure to install new filters. LEGEND ESP — External Static Pressure NOTES: 1. Maximum allowable fan speed is 18.
