manual abstract
This heat pump is provided with anchor clamps designed to hold the unit to the equipment pad in high wind conditions. Installation of the anchor clamps are recommended in all installations and are required in Florida (See Florida Building Code 301.13). To install the anchor clamps: 1. Be sure that the heat pump is in its permanent location on the equipment pad. 2. Remove the anchor clamps from the installation and instruction package. Note: Bolts and bolt anchors are not included with the heat pump. The installer must provide 1/4” x 1-3/8” stainless steel anchor bolts NO SPRINKLERSNO SPRINKLERSNO SPRINKLERS WITHIN A 6 FT. RANGE Figure 3. and the appropriate size concrete anchor to mount the clamp to the equipment pad. 3. Place the clamps at the base of the heat pump in the locations indicated in Figure 4, (2 in. undercut [notched area] on either side). HEAT PUMP HEAT PUMP 4. Fit the hook of each clamp over the lip on the base panel of the CLAMPS CLAMPS heat pump. The hook should fit between the lip of the base panel and the evaporator coil guard, see Figure 5. 5. Mark the position of the hole in each clamp on the equipment pad. Figure 4.

Standard Plumbing Layout Anchor Clamp(s) Installation, continued 6. Drill a hole in the cement using a masonry drill bit, with a diameter as determined by the concrete anchor, at each of the marks on the equipment pad. The hole should be approximately 1. in. deep. 7. Insert a bolt anchor into each of the holes. Be sure the anchors are set completely into the holes 8. Position the anchor clamps so that the holes in the clamps are over the bolt anchors. Be sure that the clamp hooks are over the lip of the heat pump base, see Figure 5. 9. Insert an anchor bolt through each clamp into the anchor and tighten to secure the clamp and heat pump to the equipment pad. Water Connections Plumbing layout See Figure 6, illustrating the standard plumbing layout with a single heat pump unit. Following the diagram from right to left, the plumbing sequence is as follows: Pool > Skimmer and Main Drain > Pool Pump > Filter > Heat Pump > Check Valve > Chemical Loop > Chlorinator > Pool NOTE: For normal installations, do not install a shut-off valve or any kind of variable restriction in the water piping between the heat pump outlet and the pool/spa. The heat pump must be protected from back-siphoning of water. If there is any chance of back-siphoning, provide a check valve between the pool and the heat pump outlet. Arrangement of pool system components other than as illustrated in Figure 6. and the following diagrams can affect the operation of the heat pump’s water pressure switch. Location of the heat pump above or below the pool water surface can also affect operation of the switch. In general, the pressure switch can be adjusted to accommodate this effect if the heat pump water connections are no more than six (6) feet below the pool water surface or no more than fifteen 15 feet above it. See instructions for pressure switch adjustment (page 20) in the heat pump start-up section of this manual for more information. If the heat pump is installed outside of this range, an external pressure switch may need to be installed in the plumbing upstream of the heat pump. Call the Pentair Water Heat Pump Technical Service department at (800) 831-7133 for details. Be advised that when pool equipment is located below the pool surface a leak can result in large-scale water loss or flooding. Pentair cannot be responsible for such water loss or flooding or the damage caused by either occurrence. 8 ThermalFlo Installation and User’s Guide Water Connections at the Heat Pump Two inch Quick Connect fittings have been installed on the water inlet and outlet connections, see Figure 7. Filtered cool water is plumbed to the inlet, located on the right side of the heat pump front panel. Heated water flows through the outlet, located on the left side of the heat pump front. Plastic piping (PVC Schedule 40) should be connected to the heat pump. The unions, provided with the unit, accept 2 in. PVC pipe. CAUTION — Make sure that flow requirements and pool water turnover rates can be maintained with the installation of additional heat pumps and plumbing restrictions. Check Valve Installation The heat pump must be protected from back-siphoning of water. If there is any chance of back-siphoning, provide a check valve between the pool and the heat pump outlet. CAUTION — The chlorinator placement, water balance, and where chemicals are added, are very important aspects of the installation. Failure to protect the heat pump un...
