INSTALLATION
Step 1—Check Equipment and Jobsite
UNPACK UNIT — Move to final location. Remove carton taking
care not to damage unit.
INSPECT EQUIPMENT — File claim with shipping company,
prior to installation, if shipment is damaged or incomplete. Locate unit rating plate on unit corner panel. (See Fig. 2.) It contains information needed to properly install unit. Check rating plate to be sure unit matches job specifications.
Step 2—Install on a Solid, Level Mounting Pad
If conditions or local codes require the unit be attached to pad,
tie-down bolts should be used and fastened through knockouts provided in unit base pan. Refer to unit mounting pattern in Fig. 2 to determine base pan size and knockout hole location.
When installing, allow sufficient space for airflow clearance,
wiring, refrigerant piping, and service. Allow 30-in. clearance to service end of unit and 48 in. above unit. For proper airflow, a 6-in.
clearance on 1 side of unit and 12 in. on all remaining sides must
be maintained. Maintain a distance of 24 in. between units. Position so snow, ice, and water from roof or eaves cannot fall directly on unit.
On rooftop applications, locate unit at least 6 in. above roof
surface. Place unit above a load-bearing wall and isolate unit and tubing set from structure.
Arrange supporting members to adequately support unit and
minimize transmission of vibration to building. Cms 2.0 user manual cameras for sale. Consult local codes governing rooftop applications.
Step 3—Elevate Unit
For proper drainage the heat pump must be raised off the mounting
surface. Fig. 4 shows unit with accessory support feet installed. Use accessory heat pump snow rack in areas where prolonged subfreezing temperatures or heavy snow occur. Refer to separate Installation Instructions packaged with the accessories.
For proper unit operation and reliability, this unit must be
installed with the field-supplied balance port, hard shut-off TXV. Do not install with evaporator coils having capillary tube metering devices.
Step 4—Remove Indoor AccuRater® Piston and Install
TXV
After removing existing AccuRater from indoor coil, install
field-supplied bi-flow hard shut-off TXV kit. (See Fig. 5 and 6.) For TXV kit part number and charging instruction, refer to TXV label in your unit. If the indoor unit (fan coil) comes factory- equipped with a bi-flow hard shut-off TXV, no TXV change is required.
