The size ranges offered by heem allow you to mix or match components to meet actual job requirements, thus eliminating the need to use oversized or undersized equipment. quipment sized to meet the actual load will provide better operating economy, better humidity control, and longer equipment life. With an air cooled system, you have no water or sewer connections to make, and no troublesome and costly water treatment problems. Since the emote Heat Pump unit is located outside the building, and the low profile air handling unit can be installed in the drop ceiling or in the conditioned space, you will not need a separate equipment room which takes up valuable building space. emote mounting of the already quiet heat pump unit keeps the compressor and condenser fan noise outside, and the vertical discharge fans carry the sound up and away from the surrounding area. Because of the simple design of the heem emote Heat Pump unit, installation is quick and simple, and very little maintenance is required. nergy fficiency atings ( s) to 9.6!

The powder coat paint finish is high gloss, durable and capable of withstanding a 1000-hour salt spray test per ASTM B 117. The unit is of the frame and panel type of construction secured by 1000-H screws. This allows all access panels to be opened or removed without affecting the structural strength of the unit. Stamped louvered panels offer 100% protection for the condenser coil. BAS PAN Galvanized steel with powder coat paint finish. SVIC ACCSS Control box with separation between line and control voltages, as well as compressor and other refrigerant controls are accessible through removable panel without affecting normal operation of unit. Condenser fan motors are mounted on removable top panels which bring the motors out to you and expose entire condenser coil for cleaning. CMPSS The Scroll Compressor is hermetically sealed with internal high temperature protection, and durable insulation on motor windings. The entire compressor is mounted on rubber grommets to reduce vibration and noise. CANKCAS HAT Minimizes refrigerant migration to compressor sump. CILS Constructed with copper tubes and aluminum fins mechanically bonded to tubes for maximum heat transfer capabilities. All coil assemblies are leak tested up to 450 PSIG [3100 kpa] internal pressure. FIGANT CNNCTINS All field sweat joints are made external of the unit and are located close to the ground for a neat looking installation. HIGH PSS CNTL Manual reset control deactivates system if abnormally high pressure occurs. HT GAS SNS Control prevents damage to compressor under abnormal conditions; loss of charge protection. SVIC VALV Standard on liquid line, optional on suction line. CNNS FAN MTS irect drive, single-phase permanently lubricated PSC motors with inherent overload protection. TANSFM 75 VA step-down type, from Line to 24 volts. CNTACT The contactor is an electrical switch which operates the compressor and outdoor fans. Its 24 volt coil is activated on a call for cooling or heating. CAPACITS Help provide starting torque necessary to boost the condenser fan motors to operating speed by directing their stored energy to the starter winding in step with the running winding. VSING VALV Sized for maximum capacity and efficiency, 24V coil, energized in heating. TIM TMPAT FST CNTL sed when unit is in heating mode to defrost outdoor coil. TX VALV sed when unit is in heating mode and outdoor coil functions as evaporator. SCTIN LIN ACCMLAT To prevent slugging of compressor. FILT I Installed in liquid line. QIPMNT GN Lug for field connection of ground wire. TSTING All units are run tested at the factory prior to shipment. nits are shipped with a holding charge of nitrogen. 7.5 & 10 TN MLS [26 & 35 kw] CNTL BX CMPSS CMPATMNT heem Manufacturing Company 3

10 GNAL INSTALLATIN The emote Heat Pump unit must be installed outdoors. It should be located as near as possible to the indoor section to keep connecting refrigerant tubing lengths to a minimum. The unit must be installed to allow a free air flow to the outdoor coils. If several units are installed adjacent to each other, care must be taken to avoid recirculation of air from one remote heat pump to another. In all installations, adequate space must be provided for installation and servicing. IGGING 075 & 100 MLS The outdoor unit must not be connected to any duct work. o not locate unit under a roof drip; if necessary, install gutters, etc., to prevent water run-off from hitting the unit. To prevent air recirculation, it is recommended that the unit not be installed under an overhang, but if necessary allow a minimum of 60 inches [1524 mm] above the unit for air discharge. SLAB INSTALLATIN emote Heat Pump units should be set on a solid level foundation. When installed at ground level, the unit should be placed on a 6 inch [152.4 mm] cement slab. If the pad is formed at the installation site, do not pour the pad tight against the structure, otherwise vibration will be transmitted from the unit through the pad. FTP INSTALLATIN If rooftop installation is required, make certain that the building construction is adequate for the weight of the unit. (efer to physical data chart.) Before placing the unit on the roof, make certain that the nylon rigging slings are of sufficient length to maintain equilibrium of the unit when lifting. nder no circumstances should the unit be lifted by only one corner for rooftop installation. 10 heem Manufacturing Company
