QTime delay fuses or “HACR” type circuit breakers must be used for 60 and smaller sizes. Standard fuses or circuit breakers are suitable for sizes 70 and larger.

RBased on wire suitable for 75° C. Other wiring materials must be rated for marked “Minimum Circuit Ampacity” or greater.

SBased upon Table 250-95 of N.E.C. 1993. See electrical data for basic heat pump for Circuit A wiring specification requirements.

IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly size fuses and conductor wires in accordance with the National Electrical Code and all existing local codes.

Manual 2100-324

GENERAL INSTRUCTIONS

IMPORTANT

The equipment covered in this manual is to be installed by trained, experienced service and installation technicians. All duct work, supply and return ducts, must be properly sized for the design air flow requirement of the equipment. ACCA is an excellent guide to proper sizing. All duct work or portions thereof not in the conditioned space should be properly insulated in order to both conserve energy and prevent condensation or moisture damage.

SHIPPING DAMAGE

Upon receipt of equipment, the carton should be checked for external signs of shipping damage. If damage is found, the receiving party must contact the last carrier immediately, preferably in writing, requesting inspection by the carrier’s agent.

GENERAL

The refrigerant system is completely assembled and charged. All internal wiring is complete.

The unit is designed for use with or without duct work. Flanges are provided for attaching the supply and return ducts.

These instructions explain the recommended method to install the air cooled self-contained unit and the electrical wiring connections to the unit.

These instructions and any instructions packaged with any separate equipment required to make up the entire heat pump system should be carefully read before beginning the installation. Note particularly “Starting Procedure” and any tags and/or labels attached to the equipment.

While these instructions are intended as a general recommended guide, they do not supersede any national and/or local codes in any way. Authorities having jurisdiction should be consulted before the installation is made.

FIELD INSTALLED HEATER PACKAGES (OPTIONAL)

These packaged heat pumps are manufactured without supplementary electric heaters. Supplementary heaters EH5PB series (to fit P1142A3, P1148A1, and P1160A1) are available for simple, fast, field installation.

A separate field power circuit is required for the supplementary heaters.

IMPORTANT: Refer to Table 4 and 5 when designing duct work for maximum available

static pressure with heater installed.

Refer to the electrical data shown on pages 2 and 3 for proper application information on all available heater combinations and what units they can be used with. It also shows the applicable circuit ampacities, fuse size, and wire size for each heater combination.

Refer to the installation instructions packed with the heater for details on how to insert it into the basic unit.
