AFFINITY SINGLE STAGE HYDRONIC INSTALLATION MANUAL

Accessories and Options

Earth Loop Pump Kit (Field Installed)
A specially designed one or two-pump module provides all
liquid fl ow, fi ll and connection requirements for independent
single unit systems (230/60/1 only). The one-pump module
is capable of 20 feet of head at 16.0 GPM, while the two-
pump module is capable of 40 feet of head at 16.0 GPM.
Hot Water Generator (Factory Installed, 040, 050,
060, and 075 Only)
An optional heat reclaiming hot water generator coil
constructed of vented double-wall copper construction
suitable for potable water is available. The coil is factory
mounted inside the cabinet. A DPK5 pump kit is required
(fi eld installed), which includes a HWG tank connection and
a temperature limit pump shutoff.
Load-side Pump Kit (Field Installed)
Four (4) load pump kits are available to provide all liquid flow
requirements for independent single unit systems (230/60/1
only). Part number 24S516-10 (Grundfos UPS15-42RU) is a
composite body pump. EWPK2 (Grundfos UP26-64BF) is a
bronze body pump. Bronze or composite body pumps should
be used when water conditions exist that are not compatible
with cast iron or for applications such as domestic water
heating. Part number EWPK1 (1" FPT flange) and EWPK3 (1
1⁄4" FPT flange) come with a cast iron body pump (Grundfos
UP26-99F) that can be used for hydronic heating applications.
Calculate the system pressure drop then refer to the pump
curves to select the proper pump. All four of the pump kits can
be used for hydronic heating applications as long as they meet
the fl ow requirements. If the fl ow requirements are outside the
pump curve, an alternate pump will need to be obtained to
maintain the necessary fl ow.
IntelliStart ®
The optional IntelliStart single phase soft starter will reduce
the normal start current (LRA) by 60-70%. This allows the
heat pump to go off-grid. Using IntelliStart also provides a
substantial reduction in light fl icker, reduces start-up noise,
and improves the compressor's start behavior. IntelliStart
is available in a fi eld retrofi t kit (part number IS60RKL or
IS60RKS) or as a factory installed option.
Water Connection Kits (Field Installed)
Water connection kits are available to facilitate loop side
and load side water connections.
