GENERAL INSTRUCTIONS
IMPORTANT
The equipment covered in this manual is to be installed by trained, experienced service and installation technicians. Any heat pump is more critical of proper operating charge and an adequate duct system than a straight air conditioning unit. 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
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 EH3P series (to fit PH1224, PH1230, and PH1236) are available for simple, fast, field installation.
A separate field power circuit is required for the supplementary heaters.
IMPORTANT: Refer to Table 4 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.
