“IMPORTANT - This product has been designed and manufactured to meet ENERGY STAR®

criteria for energy efficiency when matched with appropriate coil components. However,

proper refrigerant charge and proper air flow are critical to achieve rated capacity and

efficiency. Installation of this product should follow the manufacturer’s refrigerant charging

and air flow instructions. Failure to confirm proper charge and air flow may reduce energy

efficiency and shorten equipment life.”

TO THE INSTALLER Carefully read all instructions for the installation prior to installing unit. Make sure each step or procedure is understood and any special considerations are taken into account before starting installation. Assemble all tools, hardware and supplies needed to complete the installation. Some items may need to be purchased locally. After deciding where to install unit, closely look the location over - both the inside and outside of home.

CODES AND REGULATIONS The GPH M-Series heat pumps are designed for OUTDOOR USE ONLY. *PH M-Series is available in cooling capacities of 2, 2.5, 3, 3 1/2 and 4 nominal tons of cooling. Optional field installed heat kits are available in 5,8,10,15 and 20 kW. The units can be easily installed in manufactured or modular homes with existing high-static duct work. The units can also be easily converted to accommodate a plenum for normal or low-static applications.
PAGE 6
GROUND LEVEL PRE-INSTALLATION DETAILS The unit should be set on a solid, level foundation - preferably a concrete slab at least 4 inches thick. The slab should be above ground level and surrounded by a graveled area for good drainage. Any slab used as a unit’s foundation should not adjoin the building as it is possible that sound and vibration may be transmitted to the structure. ROOF TOP PRE-INSTALLATION DETAILS Ensure that the roof is weather tight and allows proper drainage of condensation.
PAGE 7
RIGGING DETAILS Rigging IMPORTANT: If using bottom discharge with roof curb, duct work should be attached to the curb prior to installing the unit. Lower unit carefully onto roof mounting curb. While rigging unit, center of gravity will cause condenser end to be lower than supply air end. CIRCULATING AIR AND FILTERS AIR FLOW CONVERSION Units can easily be converted from horizontal to down discharge air flow delivery.

cleaning. When installing filters, ensure the air flow arrows on the filter are pointing toward the circulator blower. Refer to the unit filter size chart below for filter size information. (SQ. FT.) 7 Nominal Filter Area Square Feet NOTE: Filters must have adequate face area for the rated quantity of the unit. See the air delivery table below for recommended filter size. Size the filters in accordance with their manufacturer recommendations.

4. If the outdoor ambient is above 80°F, the unit may trip on its high pressure cut out when on heating. The compressor should stop. The heating cycle must be thoroughly checked, so postpone the test to another day when conditions are more suitable. DO NOT FAIL TO TEST. 5. If the outdoor ambient is low and the unit operates properly on the heating cycle, you may check the pressure cutout operation by blocking off the indoor return air until the unit trips. 6.
PAGE 11
Optional Outdoor Thermostat (kit OTHPPKG-01) This outdoor thermostat is an optional accessory that is pre-set from the factory at 37°F. No other field setting is required. It comes enclosed in a “birdhouse” and should be mounted on the corner panel near the control panel. Once the ambient temperature falls below the set temperature of 37°F during heating operation, the thermostat closes and forces the two-stage compressor to run in high stage.

Suggested Field Testing/Trouble Shooting 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Run unit in the heating mode (room thermostat calling for heat). Check unit for proper charge. NOTE: Bands of frost on the condenser coil indicate low refrigerant charge. Shut off power to unit. Disconnect outdoor fan by removing the outdoor fan motor wire from “DF2” on defrost control. Restart unit and allow frost to accumulate. After a few minutes of operation, the unit’s defrost thermostat should close.

c. If subcooling and superheat are high, adjust TXV valve superheat, then check subcooling. d. If subcooling is high and superheat is low, adjust TXV valve superheat and remove charge to lower the subcooling. NOTE: Do NOT adjust the charge based on suction pressure unless there is a gross undercharge. 4. Disconnect manifold set, installation is complete.

PACKAGE UNITS - HEAT PUMP AND AC UNITS HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS We strongly recommend a bi-annual maintenance checkup be performed by a qualified service agency before the heating and cooling seasons begin. An alternate cleaning method is to use one of the products listed in the technical publication TP-109 (shipped in the literature bag with the unit) to clean the coils. The cleaners listed are the only agents deemed safe and approved for use to clean round tube aluminum coils.
