WARNING This Heat-Timer valve is strictly an operating valve; it should never be used as a primary limit or safety control. All equipment must have its own certified limit and safety controls required by local codes. The installer must verify proper operation and correct any safety problems prior to the installation of any Heat-Timer equipment.
HWR Platinum control resets the hot water temperature based on outside temperature. The operation of the actuator allows the hot supply and the cold supply to be interchangeable, allowing additional flexibility in the installation of the valve. HEAT-TIMER CORP. 059700–00 REV. B...
The valve and actuator do not require any formal maintenance to operate. The internal lubrication of the actuator is sufficient for the life of the actuator. Cleaning Any cleaning of the actuator external enclosure should be done with a light detergent with a low level of chemical aggressiveness. 059700–00 REV. B HEAT-TIMER CORP.

General tool kit (screwdrivers, wire strippers, power drill, pipe wrenches, etc.) • 1/2”, 14mm, and adjustable wrenches • 18 AWG cable (Heat-Timer p/n 703001-01 or equivalent #18/2 cable) for actuator wiring • Electrical conduit as required by local or state requirements HEAT-TIMER CORP.
– Use isolation valves to isolate system components. – Use unions to allow for servicing and, if required, removal of the valve and other components. – Include drain valves to assist in servicing the valve. 059700–00 REV. B HEAT-TIMER CORP.
(21.7 - 19.7) x (21.7 - 19.7) Refer to “Valve Specifications” on page 7 and select the valve size where the C v matches or exceeds the 262. In this example, a 6” two-way single or double-seated valve. HEAT-TIMER CORP. 059700–00 REV. B...
SINGLE-SEAT VALVE - 2-WAY OR 3-WAY COVER AND BOLTS Install the valve body while observing the following precautions: • Reference the labeling and casting marks on the valve body to ensure proper direction of flow through the valve body. 059700–00 REV. B HEAT-TIMER CORP.

(see Figure 4). • DO NOT install motorized valves upside down. Doing so can stress the valve stem. FIGURE 4 ACCEPTABLE VALVE BODY AND ACTUATOR ORIENTATION 059700–00 REV. B HEAT-TIMER CORP.
Secure the U-bolt (8) in place with two locking nuts (7), ensuring the locking nuts are tightened evenly. NOTE: If the locking nuts are not tight the actuator could potentially make a grinding noise and potentially damage the actuator. HEAT-TIMER CORP. 059700–00 REV. B...
The mounting surface should be flat and strong enough to hold the weight of the transformer. • DO NOT mount the device in a location where it will be exposed to extreme heat, cold, humidity, or moisture. Secure the transformer(s) to the mounting surface using two screws (not supplied). 059700–00 REV. B HEAT-TIMER CORP.
Run the other transformer wire through one of the actuator wiring entry fittings (3) and connect it to actuator terminal N. Place the actuator faceplate on the actuator and secure it with four screws (1). Restore power to the circuit powering the actuator transformer. HEAT-TIMER CORP. 059700–00 REV. B...
