Installation Checklist - Whirlpool Residential Electric Heat Pump Installation Instructions And Use & Care Manual

INSTALLATION CHECKLIST

Water Heater Location
□ Centrally located with the water piping system.
□ The flooring beneath the water heater must be able to
support the weight of the water heater when filled with
water (See Table 1).
□ Located indoors (such as a basement or garage)
and in a vertical position. Sheltered from freezing
temperatures.
□ Provisions made to shelter the area from water
damage. Metal drain pan installed and piped to an
adequate drain.
□ Sufficient room to service the water heater.
□ The water heater must have unrestricted airflow and
requires a minimum installation space of 750 cubic feet.
As an example, a room that has an eight foot tall ceiling
and is 10 feet long by 9-1/2 feet wide would contain
760 cubic feet. See The Confined Space Installation
section of this manual for installing the water heater in
spaces of less than 750 cubic feet.
NOTE: This Heat Pump Water Heater may be located
within a required minimum
on the inlet or outlet side, however for future service
considerations a minimum clearance of 3 feet from
any obstruction on the left and right side (air inlet and
outlet) is recommended.
□ The unit cannot be placed into any type of closet or
small enclosure.
□ The site location must be free from any corrosive
elements in the atmosphere such as sulfur, fluorine,
and chlorine. These elements are found in aerosol
sprays, detergents, bleaches, cleaning solvents, air
fresheners, paint, and varnish removers, refrigerants,
and many other commercial and household products.
In addition excessive dust and lint may affect the
operation of the unit and require more frequent
cleaning (See "Cleaning the Heat Pump" section).
□ Ambient air temperature must be above 45°F and
below 109°F. If the ambient air temperature falls
outside these upper and lower limits the electrical
elements will activate to meet the hot water demand.
Water System Piping
□ Temperature and pressure relief valve properly
installed with a discharge pipe run to an adequate drain
and sheltered from freezing (See Figure 5).
□ All piping properly installed and free of leaks.
□ Heater completely filled with water (See "Water Piping
System" section).
□ Closed system pressure buildup precautions installed
(See "Closed System/Thermal Expansion" section).
12
of 6" clearance from a wall
□ Mixing valve (when applicable) installed per
manufacturer's instructions (See "Water Temperature
Regulation" section).
Condensate Drain Line Installation
□ Must be located with access to an adequate drain or
condensate pump.
□ Condensate drain lines installed and piped to an
adequate drain or condensate pump (See Figure 4).
Electrical Connections
□ This water heater requires a 240 VAC single phase 25
amp power supply. DO NOT use a 208 VAC service.
□ Wiring size and connections comply with all applicable
codes or in the absence of local or state codes follow
NFPA-70, the National Electrical Code-current edition.
□ Water heater and electrical supply are properly
grounded.
□ Wiring enclosed in approved conduit (if required by
local codes).
□ Proper overload fuse or circuit breaker protection
installed.
Post Installation Review
□ Understand how to use the User Interface Module to
set the various modes and functions (See "Adjusting
the User Interface Module/Operating Modes" section).
□ Hybrid Mode is the recommended Operating Mode.
Understand the various Operating Modes and which
mode may be best based on season, ambient
temperature, and usage (See "Operating Mode
Description" section).
NOTE: It may be necessary to temporarily change
modes if for example filling a spa or hot tub.
□ Understand the importance of routine inspection/
maintenance of the condensate drain pan and lines
(See "Inspection/Cleaning of the Condensate Drain
Pan & Condensate Drain Lines"
help prevent any possible drain line blockage resulting
in the condensate drain pan overflowing.
IMPORTANT: Water coming from the plastic shroud is
an indicator that both condensation drain lines may be
blocked. Immediate action is required.
□ To maintain optimal operation check, remove and clean
the air filter (See "Air Filter Cleaning/Replacement"
section).
□ The Installation Instructions and Use & Care Guide
should be kept with the water heater for reference.
